Holy hell, finally someone explained it the way I can understand it. Btw watched it at 5am in bed with wife and kid... because you don't need sound on viperconcept video ;)
viperconcept please excuse me if I'm unclear but I'll try to explain what the center LSD is. The center LSD is just like the front or rear one (just imagine the front is the left and the rear is the right or the other way around), the only difference being the base power repartition. That base value is the most important, as it's the value the LSD will revolve around on both entry and exit. Keep weight transfer in mind, but only the front and rear part (we'll assume front and rear diffs are locked). For the low coast setting on braking the LSD will try to send the power to the rear wheels as there is the least resisting force and the car will OVERsteer as it will act like a hand brake or low brake bias: your car is now RWD. However, on exit with a low power setting, the car will UNDERsteer because the front wheels have the least resisting force and the LSD will send power on them: your car is now FWD. Then, like the other diffs it's inverted for high values (UNDERsteer on entry, OVERsteer on exit). I hope you have understood and if not I'll try to make it short here: for a 50(front)/50(rear) repartition if your center diff is open (low values) it can go from 100/0 to 0/100 and if it is locked (high values) it will stay at 50/50. If your diff is set at 45% power and 70% coast your car will go between 50-(50x30%)/50+(50x30%) on entry (100%-70%=30%) and 50+(50x55%)/50-(50x55%) on exit (100%-45%=55%). By the way I absolutely don't know what preload does on a center diff, but I highly thank you for explaining it on a front/rear diff, I finally understood !
Viperconcept you deserve an award for your videos, I’ve been following your instructional vids for years, you are also the reason I took the step to start racing online and make me become a respectfull, sportive and comptetitive driver. I am the type that watches those videos multiple times and take notes to test it out later, LSD has always been a tricky one, even after watching your first take on iT multiple times, this one is very clear and your efforts pay off more and more every time. Fun is always key. Thanks for everything and keep it up Sir. Carry on :)
This is the best tutorial I've seen on this. I've understood it from others before but this really gives us an intuitive understanding thanks to the focusing on the tyre load graphics live as changes were made. You can just feel how the forces themselves are working.
This is one feature I love with my Audi S4's sport differential. The car is solid when accelerating and turning. It give a new meaning to turning departures from a traffic signal.
Hey Viper, nice video as always! Just wanted to point out 2 quick things on iRacing: 1) You didn’t feel a big difference changing the Drive Ramp Angle because you only had 2 clutch plates (more clutch plates = a more effective differential) and a very low preload setting. With more clutch plates, you’d feel a much bigger difference when adjusting the Ramp Angles. 2) The Cadillac isn’t a GT3 :) Keep up the good work man!
Hi! At 16:13 and 17:15 You wrote that we want to have same amount of TORQUE on different wheels. It's not right. We want to have same GRIP. And the same torque on all whells is only happens with free differential, no LSD. It's the only function of differential - to distribute torque evenly, even when one wheel is free spinning (torque on both wheels is zero)
I'm not sure its accurate to say the same "grip" either. The grip available to each tyre depends only on the instantaneous weight balance which is affected by how harshly the driver is braking/accelerating/cornering. So the LSD is tuned to *react to which tyre already has most grip* by giving it an amount of extra torque (compared to the other wheel) proportional to the extra grip that tyre has.
You are a major help for noobas like me i always thought that preload has to do with some forces on differential part which means when the differential effect will take place faster or later but it is more that this and very coplicated as i see cause there is a difference between small and big cars well very good video it is a must see for many ppl who like to understand how these things works cheers mate
Excellent work viper! Keep it like that. I hope you can make some videos with some basic setups for beginners at sims. Sometimes it is frustrating to change some things and not see some results. Hope you make some more championships because they are litt!
Merci beaucoup pour ces explications! Je connais bien le principe et le fonctionnement du DGL (LSD en anglais) mais je n'ai jamais réussi à faire de bons réglages en jeu. Ta vidéo va bien m'aider (surtout pour Project Cars 2) :)
Very informative video, along with all your other ones. You wouldn't figure that the LSD is part of stability and just as valuable as the suspension setup, but it's crucial for weight distribution for cars that are too light in the rear. Controlling the torque is just as important as distributing it, especially if your car lacks TCS, so at full throttle through a curve the wheelspin is greatly reduced. Pushing the drive tires to the ground using downforce, suspension, and LSD should work fine without the use of a TCS, since games like Forza give bonuses for higher difficulty settings.
Let's put it to simple terms: the LSD is a great tool to help the handling of your car. It gives you a lot of power to make the car behave the way you like. More acceleration lock gives you more predictability on gas, slightly less lock often gives more acelleration, but the point of losing the back gets harder to predict. The preload gives you mid corner oversteer, it makes the back tighter in faster corners and looser in the slow ones. If you like a kart-like feel you might want to try more preload. In projectCARS2, the stable setups often have less diff preload and acelleration lock to make the cars more neutral and better on the controller.
Nice tutorial man! I have one question. There are many ways to adjust over/under steer. There is springs, anti-rollbars, damping, LSD, downforce balance. But how do I know which one to adjust? Like i feel like my car has oversteer, which should adjust first? Is there a way to know which part do I need to setup?
On setup I have my priority scheme where I start setting up all the elements from the most important to the less important. My personal classification is: 1st) Downforce (when available) 2nd) Anti-roll bars 3rd) Engine 4th) Transmission 5th) LSD 6th) Suspensions/camber 7th) Dampers Generally, when you need to know which setting you have to adjust, you use your knowledge: in some cases you can even detect wrong settings just by watching the values without driving the car.
LSD is just a complicated traction control system. It's just as important as downforce to me. Especially on tight and twisty tracks. You can fix oversteer with LSD very easy. Just open the power locking effect. If you are over steering on corner exit. Corner entry understeer can be fixed by opening the coast differential. If you get your LSD right, you can run much less downforce!!! That's the big secret!!! Oops!
Grazie mille per la spiegazione chiara e ricca di esempi pratici (come in tutti i tuoi video). Rivedendo il video non ho capito bene il precarico, in particolare il fatto per cui se alto l'auto è sovrasterzante in accelerazione. Se il precarico è alto non si ritarda la sua attivazione quindi per più tempo in curva e come se l'auto avesse il differenziale impostato a basso e quindi sottosterzante? Grazie
I tried it in GT Sport on my Porsche (991) RSR '17. I set the values to maximum and minimum and tested both (to see the effects), but I didn't feel any difference in understeer or oversteer. Am I stupid or do I just have a good ability to adapt to the way cars drive? (Sorry, if my english is bad. I'm from Austria.)
*How to tell if the Limited Slip Differential works* 1. Take any car that has an L.S.D. 2. Do a burnout/elevenses (burnout is the car not moving at all, but the wheels are spinning, elevenses is when you suddenly floor it from standstill, and an I I shape will be left behind due to the wheels rotating much faster than the the speed the car is moving at, and also, a burnout works best). 3. If the wheels rotate at the same time, the L.S.D does its job. If not, it needs a rebuild.
You got it the wrong way round on the PCARS2 LSD Accel, higher setting = 90 deg is no locking effect = understeer on RWD cars Lower setting = 20 deg is max locking = oversteer on RWD cars. Check the LSD ramp angle degree pictures online.
the first type of cars uses an open differential (O.D) the O.D problem was that it transfers most of the power to the wheel that lacks grip. For example, when you corner to the right at high speeds the wight will go to the left causing the lack of traction on the right wheel and spin the right wheel. On the other hand, the LSD transfer the power where it finds traction.
Well here is a thing... When you did the coast demonstration, you did it with cars that have a lot of grip on the rear (on the rwd demo), but, for example, what if you take a car with street tires and skinny, like 205-225 on the back, and you put the coast number high, when you engine brake is actually going to create oversteer, the wheel with more weight is going to break traction because the tire doesn't have enough grip been skinny
Before watching your video, I've been having a hard time understanding LSD. People keep saying cars with LSD is good, bla bla bla. Now after watching your video I finally understand what the hell is LSD!! Thanks viperconcept. Now time to turn on GT Sport and tune it lol.
Im learning more and more each time i watch yer videos, i may not be the best driver in game, but now i have a better grasp of it. I thank you for sharing yer knowledge
Is the interpretation of PC2 LSD against the in-game description in the tuning menu? It says lower ramp angels prevent inside tyres from spinning and send power to the tyre with more grip (outside) and 90 deg mean no locking at all, while you say "max setting (highest angle) = power to the outside wheel"
LSD my favorite upgrade behind suspension and brakes its usefull in time attack just try it gives cornering traction braking traction people ignore but dont it helps u catch faster cars set faster lap times
In Project Cars 2 and iRacing the settings are actually the opposite - the smaller the ramp angle the bigger the locking effect and vice versa. 90 degrees = the LSD is actually disabled. And you have that thing written in the hint section on the right on the same screen where you state exactly the opposite...
on PC2 strangely if you set 90 on the power ramp, you feel more oversteer in acceleration. So, I think there's something wrong with the game or the game description...
Hello viperconcept! First od all - sorry for my english, it's not very well becouse I am from Poland 😀 I need to say that your lessons about settings are verry usefull, helpfull and EASY TO UNDERSTAND to a lot of begginer drivers, and let them improve their skills. Keep working, very good job 😉. But i have a question, which of these setups should be done first, and which second/last. What is the sequence? Lsd, camber, anti roll bar, dumpers? Does it matter? Please help, i need Your opinion 😋
If the game allows me to set all the elements, usually I use this sequence: 1) Downforce 2) Anti-roll bars 3) Springs/car height/camber 4) LSD 5) Transmission.
also from what i understand from the high and low coast is that the understeer from high coast happens cause engine brakes takes place slower so the car travels more to outside of the track while cornering its a time effect yes ?
Nope, the engine brake is always the same on both high and low coast. The difference is when you put low, the inside wheel to the corner decelerates more than the outside one, creating oversteer while decelerating. The contrary if you set it to high.
please do an explanation video(similar to this one) on all the car tuning setting and how to setup for all the sim racing games ; assetto corsa, project cars, iracing, raceroom experience, etc....
Hey man, great video as usual. I'm wondering if you have any tips on being able to set consistent lap times because my driving style makes me fast but inconsistent which often screws up my strategy. Thanks
don't push 100% unless it's a flying lap. only 80-90% but consistent is good. your experience will help you know the car and track better, and your race lap time will faster. I experience myself in AC online several times, I just drive smoothly with the softest tyre available and avoid any stupid accident, while the others just push hard their car ended up struggling with their tyres several laps prior to the finish line. I can make it through the finish line, and sealed the podium easily.
LSD doesn't send more power to the outside wheel, it simply locks the driven axle. You're adjusting the LSD's propensity to lock the axles under different conditions
13:37 ... so low coast and high power lsd transfer grip to the outside wheel and high coast and low power lsd transfer grip to the inside wheel. Is that correct?
From the video, I'm no expert : First part is correct, but second part is bit fishy to me. I'd say it doesn't transfer as much as it should to the outer wheels with low power LSD Or inside wheel would have more torque doesn't mean it'll have more grip Bcz weight transfer Need expert review here!
Sorry I’m a bit late to the party, but I’ll clarify this for you, and for anyone else stumbling upon this comment. In short high coast and low power does not transfer traction to the inside wheels. It locks the inside wheel more, causing the inside wheel to travel at a speed relatively more close to the outside wheel. It does give the inside wheels more wheel speed, in theory giving it more traction to the inside wheel. But it doesn’t transfer it to the inside. The outside wheel will always have the most traction, since it is bearing most of the weight of the car, because of load transfer. But I’ll break down all of the differential settings as easily as I can. This will be kind of long. While cornering the outside wheel will always travel at whatever speed is shown on speedometer. The INSIDE wheel will always travel at a LOWER speed than the OUTSIDE wheel, so that it can corner more easily. This is due to the fact that while cornering, the outside wheel must travel a greater distance than the inside wheels. The differential allows the inside wheel to “slip” allowing the inside wheels to move at a different speed than the outside wheels. Hence the name limited slip differential When you adjust the coast setting on the differential, you are adjusting how much that INSIDE wheel can “SLIP” while off throttle. Key word OFF THROTTLE. Hence the name “coast”. Adjusting the coast setting, determines how much slower the inside wheel will go while off throttle, relative to the outside wheel. Having a low coast setting allows the car to be very agile in tight corners that require you to be off of the throttle. This setting has great performance in sharp corners. Having a high coast setting causes the car to be more hesitant to turn off throttle, but allows for more traction. This is useful for tracks that have a lot of high speed corners, where you are off of the gas pedal for majority of the time. When you have a High coast setting, you are adjusting the inside wheel to travel at a similar speed to that of the outside wheel. Keyword similar, the inside wheel will never travel faster than the outside wheel, it just isn’t possible. The same principles I explained can be applied to the power setting of the LSD. The power setting is a term for when you are on the accelerator. If you have the power preset set low, it will give majority of the power to the outside wheels, allowing the inside wheels to “slip” and travel at a lower speed. While if you have the power preset high, it will evenly distribute the power to both wheels. Low preset on power, will give you great maneuverability while on the throttle. This is good for tight, consecutive corners where you are on throttle more most of the time. A higher preset on power evenly distributes power to both wheels. This is good for high speed, sweeping corners where you are on partial or full throttle most of the time. This is IMPORTANT, note that you never want to be at the LOWEST, or HIGHEST preset for any of these settings ever. You want to try and find a happy medium for whatever kind of tracks you are driving on. If you go too low or too high, you are losing out on potential time. A perfect medium is something where you have a decently neutral coast setting, so that you have a decent amount of traction and speed in both wheels, but you still maintain maneuverability. The same goes for the power setting, you want something where you have good amounts of traction to accelerate in the corner, but not something too much where you start under steering when you press on the accelerator. And one last setting to explain. The initial torque setting. This setting is how much throttle you can apply before you change from coasting, to power (aka lock). This is kind of confusing to some, but let me try to better explain this while trying to paint a picture in your head. You are going into a corner, you are off of the throttle (coasting). You are gently applying gas, not yet fully throttle. You finally pass the apex of the corner, and can apply full throttle (locking the differential now). Now that I’ve painted that picture in your head, to explain, INITIAL TORQUE, is essentially how much force, aka how much throttle it takes, until you fully lock the differential. Adjusting this is critical to maintain a good amount of speed throughout a corner. If you set it too low, the differential will lock very easily, causing your car to potentially under steer with very little throttle through the corner. Setting it too high, and you will not have enough traction in both wheels to accelerate once you have reached a straight away after you leave the corner. I hope this was helpful, I might have missed out or forgot a few details, but this is just a brief overview. For certain games they might have different names, but the general settings apply the same. I know in Gran Turismo, the differential settings are flipped, the lower the higher, and the higher the lower. I know it was a bit long, but it’s hard to condense this information into a very short summary. I suggest you guys go watch Donut Media’s video on LSD’s. It’s pretty informative, but doesn’t go very into depth.
I think when we maximizing the amount of the power LSD both wheels will have the same amount of power just like a welded differential not just powering the outside wheel like you said on the video. please enlighten me if I'm wrong
great job as always i'm wondering if you think these games are getting too detailed or complex in their settings for the majority of their players? is there such a thing as "too real" in that it makes it too hard for the average player to understand how to take advantage of them? and have you seen any games that have unnecessary settings or ineffectual ones?
Sim games have to generalize car physics without being too precise on the exact details of every car. Every single car ever produced has a different drivetrain and suspension setup, so it's kind of 'unsimulating' when you can buy a clutch for a stock 4 speed automatic, or set final drive ratio because you bought a racing transmission, even though the final drive gear is in the differential. Adjusting the suspension is going to assume the vehicle is independent all around, when in fact it has a live rear axle, which performs VERY differently than a swing axle. If we're gonna talk about simulation, then developers would have to implement every single stock option for every single vehicle, from engine, transmission, and rear end selection, to stock paint codes and performance brake options as well.
thanks Man . you deserve a like button now i understand something on the setup because i'm beginner on that. Please make a video about how to setup FFB and calibrate the wheel cause i have my first wheel racing the T150 ps4 pc . That's gonna help me a lot of.
Nice vid. Thanks. Although I do wonder why you don't just use your voice to narrate/explain. Would be quicker no ? But I like the chilled out style though 😋
You don't want to know his voice. I have my own picture of him in my mind and I don't want to spoil it with The truth 😀 you don't want to meet your heroes 😀
chill_doctor There was an episode about Direct drive wheel when I saw he has curly hair. Because of that I landed in hospital for 2 weeks. 100000% true
Since the power L.S.D. has an inverted result with the coast L.S.D, what would happen if both power and coast L.S.D. are high? Will the setup has the same effrct as the one has low power L.S.D. and low coast L.S.D?
Tiantian Zhang they don't work at the same time, power LSD works when you're accelerating, while coast works while you're, that's right, coasting. You can't accelerate and coast at the same time, so they don't nullify each other
Tiantian Zhang high on both would make your car understeer on entry (like crazy boat/muscle car amounts) and oversteer on exit (like crazy ice/muscle car amounts) while a low on both would make your car oversteer on entry (like crazy skid plates/FWD lift off amounts) and understeer on exit (like crazy ice/FWD all in amounts).
I really like some of your advice. But you are wrong about the LSD on Project Cars 2. A lower power ramp angle of 20° means more oversteer, on throttle. Especially when you add more clutches. A higher 90° Ramp angle will turn it off 100%. It also makes it much harder to power oversteer if you have an open differential (90° power ramp angle) on a rear wheel drive car. Maybe it's just the language barrier? I feel bad for saying this because you have helped me in the past. Maybe you could update the video?
Not language barrier (I switched the game language in english for this video). The thing is the car should behave like you said. But strangely, when I change the settings I experience the contrary: When I put 20° on the power ramp I get understeer, when I put 90° I get oversteer.
@@viperconcept Maybe it's the size of the rear tyres that grip too much? High grip rear tyres can cause understeer. Or maybe it's weight balance? I will try it out when I get time. Not all of the cars have realistic physics, in PC's 2, unfortunately. Some cars feel like they have been rushed with the physics. Maybe you should have tried adding more clutches? Or some other part of the differential was effecting it? Preload maybe?
Tbh i've never experienced any downside putting the power diff. to min. in every situation in AC (unless you want to drift). Perhaps it's just my crappy sensibility.

Nice tutorial man! I have one question. There are many ways to adjust over/under steer. There is springs, anti-rollbars, damping, LSD, downforce balance. But how do I know which one to adjust? Like i feel like my car has oversteer, which should adjust first? Is there a way to know which part do I need to setup?
I would say rear dampers first. Most softness is signal of more grip.
On setup I have my priority scheme where I start setting up all the elements from the most important to the less important. My personal classification is:
1st) Downforce (when available)
2nd) Anti-roll bars
3rd) Engine
4th) Transmission
5th) LSD
6th) Suspensions/camber
7th) Dampers
Generally, when you need to know which setting you have to adjust, you use your knowledge: in some cases you can even detect wrong settings just by watching the values without driving the car.
thx
how to adjust the chamber and dampers?
LSD is just a complicated traction control system.
It's just as important as downforce to me. Especially on tight and twisty tracks.
You can fix oversteer with LSD very easy. Just open the power locking effect. If you are over steering on corner exit.
Corner entry understeer can be fixed by opening the coast differential.
If you get your LSD right, you can run much less downforce!!!
That's the big secret!!! Oops!

I tried it in GT Sport on my Porsche (991) RSR '17. I set the values to maximum and minimum and tested both (to see the effects), but I didn't feel any difference in understeer or oversteer. Am I stupid or do I just have a good ability to adapt to the way cars drive? (Sorry, if my english is bad. I'm from Austria.)
*How to tell if the Limited Slip Differential works*
1. Take any car that has an L.S.D.
2. Do a burnout/elevenses (burnout is the car not moving at all, but the wheels are spinning, elevenses is when you suddenly floor it from standstill, and an I I shape will be left behind due to the wheels rotating much faster than the the speed the car is moving at, and also, a burnout works best).
3. If the wheels rotate at the same time, the L.S.D does its job. If not, it needs a rebuild.
You got it the wrong way round on the PCARS2 LSD Accel, higher setting = 90 deg is no locking effect = understeer on RWD cars
Lower setting = 20 deg is max locking = oversteer on RWD cars.
Check the LSD ramp angle degree pictures online.
Your video about setting is very useful.. I hope u can make more video about setting car 👍👍👍
We are taking a more in depth look at LSD?
cool now i have all the knowlege that i need to setup my LSD -farm-
13:12 rip earphones
Great video! Thanks viperconcept. Teach us more about different setup nuances! 😀
the first type of cars uses an open differential (O.D) the O.D problem was that it transfers most of the power to the wheel that lacks grip. For example, when you corner to the right at high speeds the wight will go to the left causing the lack of traction on the right wheel and spin the right wheel. On the other hand, the LSD transfer the power where it finds traction.
These videos are educational as muvh as they are satisfying
Well here is a thing... When you did the coast demonstration, you did it with cars that have a lot of grip on the rear (on the rwd demo), but, for example, what if you take a car with street tires and skinny, like 205-225 on the back, and you put the coast number high, when you engine brake is actually going to create oversteer, the wheel with more weight is going to break traction because the tire doesn't have enough grip been skinny
Before watching your video, I've been having a hard time understanding LSD. People keep saying cars with LSD is good, bla bla bla. Now after watching your video I finally understand what the hell is LSD!!
Thanks viperconcept. Now time to turn on GT Sport and tune it lol.
Im learning more and more each time i watch yer videos, i may not be the best driver in game, but now i have a better grasp of it. I thank you for sharing yer knowledge
Thank U very much for that lesson . I really learned alot & it made a big difference in my setups & lap times . . .
Is the interpretation of PC2 LSD against the in-game description in the tuning menu? It says lower ramp angels prevent inside tyres from spinning and send power to the tyre with more grip (outside) and 90 deg mean no locking at all, while you say "max setting (highest angle) = power to the outside wheel"
Great video viper explained perfectly. Thanks
Good video. I found that for accel 10-15 were good ranges for control and optimum traction on RWD cars. 18-23 on FWD
Finally someone explained it well thanks dude
LSD my favorite upgrade behind suspension and brakes its usefull in time attack just try it gives cornering traction braking traction people ignore but dont it helps u catch faster cars set faster lap times
In Project Cars 2 and iRacing the settings are actually the opposite - the smaller the ramp angle the bigger the locking effect and vice versa. 90 degrees = the LSD is actually disabled. And you have that thing written in the hint section on the right on the same screen where you state exactly the opposite...
on PC2 strangely if you set 90 on the power ramp, you feel more oversteer in acceleration.
So, I think there's something wrong with the game or the game description...
Hello viperconcept!
First od all - sorry for my english, it's not very well becouse I am from Poland 😀
I need to say that your lessons about settings are verry usefull, helpfull and EASY TO UNDERSTAND to a lot of begginer drivers, and let them improve their skills. Keep working, very good job 😉. But i have a question, which of these setups should be done first, and which second/last. What is the sequence? Lsd, camber, anti roll bar, dumpers? Does it matter? Please help, i need Your opinion 😋
If the game allows me to set all the elements, usually I use this sequence:
1) Downforce
2) Anti-roll bars
3) Springs/car height/camber
4) LSD
5) Transmission.
viperconcept thanks
great vid!
just a tip: hold shift while moving in free cam in assetto to move slowly :D
also from what i understand from the high and low coast is that the understeer from high coast happens cause engine brakes takes place slower so the car travels more to outside of the track while cornering
its a time effect yes ?
Nope, the engine brake is always the same on both high and low coast.
The difference is when you put low, the inside wheel to the corner decelerates more than the outside one, creating oversteer while decelerating.
The contrary if you set it to high.
Thanks for answer mate :)
please do an explanation video(similar to this one) on all the car tuning setting and how to setup for all the sim racing games ; assetto corsa, project cars, iracing, raceroom experience, etc....
Thanks a lot for all your lessons, it helped me so much!
LSD = the most important tuning adjustment you will ever make for racing games.
Hey man, great video as usual. I'm wondering if you have any tips on being able to set consistent lap times because my driving style makes me fast but inconsistent which often screws up my strategy.
Thanks
TheHitlist72 drive safer
don't push 100% unless it's a flying lap.
only 80-90% but consistent is good. your experience will help you know the car and track better, and your race lap time will faster.
I experience myself in AC online several times, I just drive smoothly with the softest tyre available and avoid any stupid accident,
while the others just push hard their car ended up struggling with their tyres several laps prior to the finish line. I can make it through the finish line, and sealed the podium easily.
Cat Car Just started doing this on PC2 and F1 2017 and it's started to get better. Each lap is within around 0.1 of the last. Thanks man
LSD doesn't send more power to the outside wheel, it simply locks the driven axle. You're adjusting the LSD's propensity to lock the axles under different conditions
13:37 ... so low coast and high power lsd transfer grip to the outside wheel and high coast and low power lsd transfer grip to the inside wheel. Is that correct?
From the video, I'm no expert :
First part is correct, but second part is bit fishy to me. I'd say it doesn't transfer as much as it should to the outer wheels with low power LSD
Or inside wheel would have more torque doesn't mean it'll have more grip Bcz weight transfer
Need expert review here!
Sorry I’m a bit late to the party, but I’ll clarify this for you, and for anyone else stumbling upon this comment. In short high coast and low power does not transfer traction to the inside wheels. It locks the inside wheel more, causing the inside wheel to travel at a speed relatively more close to the outside wheel. It does give the inside wheels more wheel speed, in theory giving it more traction to the inside wheel. But it doesn’t transfer it to the inside. The outside wheel will always have the most traction, since it is bearing most of the weight of the car, because of load transfer.
But I’ll break down all of the differential settings as easily as I can. This will be kind of long.
While cornering the outside wheel will always travel at whatever speed is shown on speedometer. The INSIDE wheel will always travel at a LOWER speed than the OUTSIDE wheel, so that it can corner more easily. This is due to the fact that while cornering, the outside wheel must travel a greater distance than the inside wheels. The differential allows the inside wheel to “slip” allowing the inside wheels to move at a different speed than the outside wheels. Hence the name limited slip differential
When you adjust the coast setting on the differential, you are adjusting how much that INSIDE wheel can “SLIP” while off throttle. Key word OFF THROTTLE. Hence the name “coast”. Adjusting the coast setting, determines how much slower the inside wheel will go while off throttle, relative to the outside wheel.
Having a low coast setting allows the car to be very agile in tight corners that require you to be off of the throttle. This setting has great performance in sharp corners.
Having a high coast setting causes the car to be more hesitant to turn off throttle, but allows for more traction. This is useful for tracks that have a lot of high speed corners, where you are off of the gas pedal for majority of the time.
When you have a High coast setting, you are adjusting the inside wheel to travel at a similar speed to that of the outside wheel. Keyword similar, the inside wheel will never travel faster than the outside wheel, it just isn’t possible.
The same principles I explained can be applied to the power setting of the LSD. The power setting is a term for when you are on the accelerator. If you have the power preset set low, it will give majority of the power to the outside wheels, allowing the inside wheels to “slip” and travel at a lower speed. While if you have the power preset high, it will evenly distribute the power to both wheels.
Low preset on power, will give you great maneuverability while on the throttle. This is good for tight, consecutive corners where you are on throttle more most of the time.
A higher preset on power evenly distributes power to both wheels. This is good for high speed, sweeping corners where you are on partial or full throttle most of the time.
This is IMPORTANT, note that you never want to be at the LOWEST, or HIGHEST preset for any of these settings ever. You want to try and find a happy medium for whatever kind of tracks you are driving on. If you go too low or too high, you are losing out on potential time.
A perfect medium is something where you have a decently neutral coast setting, so that you have a decent amount of traction and speed in both wheels, but you still maintain maneuverability. The same goes for the power setting, you want something where you have good amounts of traction to accelerate in the corner, but not something too much where you start under steering when you press on the accelerator.
And one last setting to explain. The initial torque setting. This setting is how much throttle you can apply before you change from coasting, to power (aka lock). This is kind of confusing to some, but let me try to better explain this while trying to paint a picture in your head.
You are going into a corner, you are off of the throttle (coasting). You are gently applying gas, not yet fully throttle. You finally pass the apex of the corner, and can apply full throttle (locking the differential now).
Now that I’ve painted that picture in your head, to explain, INITIAL TORQUE, is essentially how much force, aka how much throttle it takes, until you fully lock the differential. Adjusting this is critical to maintain a good amount of speed throughout a corner. If you set it too low, the differential will lock very easily, causing your car to potentially under steer with very little throttle through the corner. Setting it too high, and you will not have enough traction in both wheels to accelerate once you have reached a straight away after you leave the corner.
I hope this was helpful, I might have missed out or forgot a few details, but this is just a brief overview. For certain games they might have different names, but the general settings apply the same. I know in Gran Turismo, the differential settings are flipped, the lower the higher, and the higher the lower. I know it was a bit long, but it’s hard to condense this information into a very short summary. I suggest you guys go watch Donut Media’s video on LSD’s. It’s pretty informative, but doesn’t go very into depth.
@@whosleng genuinely perfect
I think when we maximizing the amount of the power LSD both wheels will have the same amount of power just like a welded differential not just powering the outside wheel like you said on the video. please enlighten me if I'm wrong
great job as always
i'm wondering if you think these games are getting too detailed or complex in their settings for the majority of their players? is there such a thing as "too real" in that it makes it too hard for the average player to understand how to take advantage of them? and have you seen any games that have unnecessary settings or ineffectual ones?
Sim games have to generalize car physics without being too precise on the exact details of every car. Every single car ever produced has a different drivetrain and suspension setup, so it's kind of 'unsimulating' when you can buy a clutch for a stock 4 speed automatic, or set final drive ratio because you bought a racing transmission, even though the final drive gear is in the differential. Adjusting the suspension is going to assume the vehicle is independent all around, when in fact it has a live rear axle, which performs VERY differently than a swing axle. If we're gonna talk about simulation, then developers would have to implement every single stock option for every single vehicle, from engine, transmission, and rear end selection, to stock paint codes and performance brake options as well.
Awesome video. Would love to see you explain LSD on Forza 7. Makes me wonder if LSD in F7 is broken or not.
This lesson is a bookmark
Enjoyable and informative.
Nice lesson Viper, thank you!
Great video, info and music as usual...what is the music ???
Really useful, with my compliments! Good job.
Viper will you do another epic online championship on gt sport?
I support this but PC2.
Damn, was just about to go schleep...
So High power and low coast are the ideal settings for a FWD car?
Woah, this is a great guide, thanks....!
This guide will be great for me as controller user.....
Nice, using Daisuke's gran turismo 5 jazz menu music
Amazing as always
I am voting for adding Polish subtitles with using such words like:
Wzdłużny balans obciążenia, Blokada wiskotyczna LSD,
Szpula
:D
thanks Man . you deserve a like button now i understand something on the setup because i'm beginner on that. Please make a video about how to setup FFB and calibrate the wheel cause i have my first wheel racing the T150 ps4 pc . That's gonna help me a lot of.
Older games like Gt 2 which the game im currently playing on doesn't have this LSD, it works very differently
I have one question: can the LSD be considered somewhat of an assistance? I mean, those settings can really solve some big problems while cornering...
Nice vid. Thanks. Although I do wonder why you don't just use your voice to narrate/explain. Would be quicker no ? But I like the chilled out style though 😋
Everything with his respective style, in this rhythm you can understood the explication.
You don't want to know his voice. I have my own picture of him in my mind and I don't want to spoil it with The truth 😀 you don't want to meet your heroes 😀
KubaMCCU lol. You have a point. I was kinda hoping it was a she tbh lol.
chill_doctor There was an episode about Direct drive wheel when I saw he has curly hair. Because of that I landed in hospital for 2 weeks.
100000% true
KubaMCCU lmfao
This video explains it so well. Thanks!
Great video, very informative!!!
9:13 Max setting in degrees is 90º or 0º??? I'm confused
I mean. Which one is locked and which one not???
This analyses videos are great
Next lesson: how to Viperconcept setup his AWD cars more in depth
is that first music from Metropolis Street Racer?
its only a game... by that theory you should care about wheel size/tyres diam. too...it gives diferent momentum/balance chasis force
How do you pause and "roam" around the car like that in AC?
Isn't an LSD's job is to distribute even power to BOTH wheels? Why does viperconcept say it transfers all power to the outside wheel?
I didn't say that.
You just said that lsd preload helps maneuver, but what actually is it? Not just what it does?
Damn, I need to sit down with notebook and take notes. But I feel it’s worth it 😃
Me encanta tu canal bro
Tiene videos muy interesantes
Saludos desde México
To know what this or that does, you need to maxed or lowered your settings one by one
Another great video, it will help me a lot.. Thanks ;)
Now that you've known about LSD, how about DMT?
Joe Rogan has entered the chat
Excellent video!
Since the power L.S.D. has an inverted result with the coast L.S.D, what would happen if both power and coast L.S.D. are high? Will the setup has the same effrct as the one has low power L.S.D. and low coast L.S.D?
Tiantian Zhang they don't work at the same time, power LSD works when you're accelerating, while coast works while you're, that's right, coasting. You can't accelerate and coast at the same time, so they don't nullify each other
Tiantian Zhang high on both would make your car understeer on entry (like crazy boat/muscle car amounts) and oversteer on exit (like crazy ice/muscle car amounts) while a low on both would make your car oversteer on entry (like crazy skid plates/FWD lift off amounts) and understeer on exit (like crazy ice/FWD all in amounts).
you will ended up being on grass or gravel
this video helped me a lotttt
I really like some of your advice.
But you are wrong about the LSD on Project Cars 2.
A lower power ramp angle of 20° means more oversteer, on throttle. Especially when you add more clutches.
A higher 90° Ramp angle will turn it off 100%. It also makes it much harder to power oversteer if you have an open differential (90° power ramp angle) on a rear wheel drive car.
Maybe it's just the language barrier?
I feel bad for saying this because you have helped me in the past.
Maybe you could update the video?
Not language barrier (I switched the game language in english for this video).
The thing is the car should behave like you said.
But strangely, when I change the settings I experience the contrary:
When I put 20° on the power ramp I get understeer, when I put 90° I get oversteer.
@@viperconcept
Maybe it's the size of the rear tyres that grip too much? High grip rear tyres can cause understeer. Or maybe it's weight balance?
I will try it out when I get time.
Not all of the cars have realistic physics, in PC's 2, unfortunately.
Some cars feel like they have been rushed with the physics.
Maybe you should have tried adding more clutches? Or some other part of the differential was effecting it?
Preload maybe?
Perfect video
Tbh i've never experienced any downside putting the power diff. to min. in every situation in AC (unless you want to drift). Perhaps it's just my crappy sensibility.
