- We hear a lot about engine mapping from the drivers and engineers. The driver will change engine maps throughout the race for different reasons, but what do these engine maps do and how do they affect the car?

Couple more of those vids and i am starting an f1 team
Only a small loan of $500 million needed
F1 2020 do be a pretty exciting game
@@drdoomgoat38 Not anymore, $150 million is the limit now.
i guess Im asking the wrong place but does anybody know a way to log back into an Instagram account?
I was stupid forgot the account password. I would love any tips you can give me!
@Alejandro Francis Instablaster =)
Already watched on Autosport but always watching it again! Can you make a video about suspensions and suspensions setups?
Thank you so much for making these awesome videos!!!!!!!!!
Same goes for me.
I watch the video on Autosport but don't bother watching again. Videos are awesome, but not dense enough to require watching twice. I'm not sure they should be.
Money money money but he deserves it
Check donut media
@An0n completely forgot this comment but I guess
f***ing finally
I didn't know that you could tweak the power of the engine aside from fuel mixes. I thought it was just about applying certain pressure on the pedal but there's a lot more to it!
Please continue to make complicated stuff easy for us people. :)
Actually, in order to optimize energy saving against lap time, the ECU can control the torque delivered if maximum torque is requested by the driver (100% throttle). Furthermore, the torque is controlled by deciding on the torque split between MGU-K and ICE. There are several papers on that topic.
So engine mapping is only 1 part of the equation with the current powertrain architecture
I think it's awesome how the illustrations you make help so much to understand everything, yet being so simple and intuitive!! Keep the awesome work coming!!! Would love to see a video about suspensions pleaseeee!!
I rarely understand your videos but I find them utterly compelling. Thanks so much for producing them.
I learnt so much from this 8 min video. You are very underrated and deserve a million subscribers.
I love all the neat stuff that comes from this channel.
I commented a week ago suggesting you slow your narration a bit, and you did. Thank you very much chain bear! :)
I've done my final degree project about this with a real engine. When I get asked about what It consists of, I find it very difficult to explain it without using technical and difficults terms but my god you have done it perfectly.
Awesome vid man, extremely helpful to understand with your explanation and awesome animation as well
Excellent explanation, as usual.
Thanks for sharing.
Finally a RUclips video that jumps right in without the 5 min waffling intro
Could you explain the limit that Renault gave Red Bull for their “Engine mode” on the engine near the end of the race? (Japan GP) It was on radio, when Max was behind Bottas? Is it regulated by the sport, the team, or the engine manufacturer? 🤔
Renault will effectively tell the teams it supplies "you can put this many minutes on this engine on setting 7 and this many on setting 5. More than that and you run the risk of it failing and your race is over". It's advice from the engine manufacturer, but as a team you don't /need/ to adhere to it - it's not a rule that is enforced by anyone - just some advice from the people who build the power unit.
basically ^ this. F1 engines are very precisly engineered for both power and weight saving, and just like your own road cars components will fail faster when driven too hard for long periods of time. This means that the engines reliability across a race weekend can often only be estimated, and the manufacturers give guidelines to the teams using their engines as to how long you can run an aggressively push an engine before it's risk of faliure becomes too high. The current rule limits on how many engines you can use per season as well really push the teams to follow these guidelines and conserve the engines as much as possible.
@@H18136 and the base of the warranty of the parts. Beside Raikkonen did a good job at managing the distance. Even tho Verstappen got into DRS range he couldn't get into position to attack.
Excellently exposited, thank you CB.
Love your work! Amazing!
You're channel is awesome. Great job.
I always watch on autosport channel where it comes out first, but I always come back to like and listen to the Q&A.
Such a brilliant explanation
Excellent presentation...
Thanks
Very Nice video! Definitely a topic to torque about!
You explained it in really excellent way
this video is too good !
great job
This explanation is incredible, and it goes beyond F1. Even our very own street cars ECUs work like this.
Superb video!!
Is "party-mode" an engine mapping setting? Presumably, one that pushes the outputs towards the extreme edges of these maps, without killing the engine, or damaging it too much.
That's what I understand of it.
As I understand it it's more related to the interplay of the Hybrid drive unit, fuel mixes and ignition timing - things more managed by the ECU than necessarily related to throttle response.
What such a mode is will depend on what the ECU is programmed like, but generally speaking, such a mode will push way more fuel through the engine than would be sustainable for an entire race given current fuel limitations, and most likely also completely drain the battery without bothering to charge it up again as you normally would. How exactly it directs the MGU-H I wouldn't know, and it is an interesting one, because there will be a sweet spot in using the electric energy, between driving the turbo to eliminate lag and making the combustion engine work as well as possible, and driving the wheels directly.
+ISLAMATRON - I know there's a 100kg/h limit on fuel flow at any moment, but I think you'll find that if you try to push 100kg/h through the engine at all times, you'll get nowhere near the chequered flag in most grands prix, hence why I said fuel flow was higher than would be sustainable for an entire race...
Great video boss.
Pure brilliance!!
Riccardo's engine doesn't need an engine map.
It's treasure is lost forever.
More like an engine post-it note.
It has a map... back to the pits :)
all inputs go to back to pit
Milos
Very useful video, thank you.
Best F1 vids hands down
Great job
Didn't watch this on autosport so i could watch it here. Worth the wait.
Yaaaaay a new video!
Very nice video
Thanks. It is fully clear.
Hey chain bear 👋
Another very interesting video, thank you for your time and effort.
In this video I had a first time of confusion while your explanations.
@0:30 your drawing displays a throttle with arrows from the fuel tank to the engine. The combustion engine in f1 has direct injection, hasn't it? Wouldn't it be more precise if the throttle only controls the input air as the fuel is injected directly into the cylinders?
Even in the audio you state the throttle controls air _and fuel _...?
PS: never mind, you said "way back in time" overheard it, sorry 🙏.
Great videos. How about one on practice and qualifying strategies?
very cool. thanks!
Thanks bear :)
This was another good one ... well worth a second watch.
great content 👍👍 could you do a video on track design and history(why some are loved while others are boring, how they are designed etc.)?
Sathwik Atluri I think you should watch the video’s about race lines and there he explaines what makes a corner a good corner thus an interesting trac. Maybe not Exactly what you ment but there is a beginning.
@@MrFlorianking thx
i was waiting this episode for more than a year, i really couldnt understand enging maping ans start mapping before
Hello Chainbear, great Video. Could you maybe explain some of the setup work done on an f1-weekend and how the team behave with that? Is the setup available to the team-mate for instance?
It is 4 am in the morning, I am watching this video and I don't even have a car
Same ikr
Spot on
Can you please make a video of how teams get the position of thier pit boxes. Is it better to have your pit box at the beginning of the pit lane or at the end.
Great vid again, I'm surprised you're not affiliated with F1 yet!!
Nice!
Does the ECU know about what gear the car is in? Can the maps be tuned for each gear?
You’re a bloody genius! 😂
I saw it on autosport but I resisted watching it and finally made it here
Same here.
Lol, same. 😂😂
can you make a video on quali trim vs race trim, i have not found 1 video explaining this, thanks
Hello, nice video. I have a question. On minute 1:37 you mentioned that the inputs for a simple engine torque maps are throttle percentage and rpm. The output will be torque.
Is there any mathematical relation I can follow to manually calculate this example with your values (rpm=8500)(.83)(212 Nm)?
I swear, the ending music still reminds me of the Grid Autosport theme.
I dont really good at English. But thanks for the video . It's amazing . Do you have an online class about the engine ? I want to learn more .
What are your thoughts on the recently announced W Series?
Would it be beneficial to have dynamic mapping? Where maps change based off the next corner or bend.
Chain bear can u do a video on Ocon and K Mag fuel related DQs
rich/lean at the end... now you get close to piston aircraft engine controls! :)
Does the system also reduce the air intake along with the fuel?
Great again. How do you know all this???
Which driver in the lower formulas do you think could win the WDC one day?? And which drivers from other motorsports could win the WDC. Kinda cheating with 2 questions in one but just curious on your thoughts
Dont know about F1 Cars, but in a normal car it is air Filter > throttle flap > carburetor. This the line to the fuel tank is connected to the carburetor and fuel doesn’t hit the throttle flap, as ist enters the air later.
please do a video on f1 suspensions
Do they switch to a different engine map when they are in the pit lane? Or do they use something else?
I should imagine they do, yes. They could get away with just making the pit lane button a speed limiter, but any engine manufacturer worth their salt will try to incorporate some sort of engine mapping there that finds a balance between using as little fuel as possible while in pit lane, while keeping engine temperatures within the window, and the throttle response sharp enough for a quick getaway from the pit box.
Good video. But I think they don't have a throttle valve anymore as even a fully open one has a drag. I think they control the torque by the MGU-H as a throttle and a very low fuel mixture as they don't have enough fuel to slow down the engine by too much fuel.
CB, do you think tyre wars will happen again within the next 10 years?
can it be remapped to make it more economical?? increase mpg?
While this basics are correct, the idea that the most torque is being produced at the greatest rpm is not right. Most engines don't work that way. This is why you have a torque/power band graph. The power band will usually cross the torque line twice. Once at the beginning of the power band's optimal low rpm output and again as the power band peaks out and output starts to fall. Usually, the tachometer is calibrated to red line shortly after the power band peaks because now you are over-revving the engine and this can cause damage.
Note to self, a too high of a engine torque results in wheel spin if tire grip cannot handle the force taken.
Chainbear could make a 30 minute video about rocks and I would throw away everything and listen
How did you know what my next video was??
Chain Bear F1 - this video did not cover party modes or expected life of an engine. Given that Red Bull / Honda changed an engine early, can you please cover a manufacturers' best options for the rest of the season! Is it ever worth using an engine for more than 7 races, or is it always better to take an engine penalty?
Already seen this on autosport. Why bother coming back here to watch it again? 😳
Why do these appear twice in my feed all the time?
This would be great for the f1 game .
Cheers CB! Great video. Totally demonstrates another way the driver matters in the end and how Hamilton is totally in the zone with his merc and no one could touch him on the Suzuka track.
I need program for remapping !
who made you that font?

My new motorcycle comes with 3 different mapping plugs. I’m just trying to find out what they do.
#Maldonado2ToroRosso2019
Well, I suppose it would be one solution to make F1 more interesting: Bring back the big crashes! :p
Watch as Toro Rosso uses Maldonado to obstruct the other teams
You should upload here before you post at autosport ...
I don’t want to give the views to Autosport
But I watch here again .....
love your vedios ..
Imagine a control map that made driving the cars like a racing game with a keyboard.
*How do you know all these things mate ??*
Is this basically what the formula e 'throttle mapping' penalties are being given for, or is that a different thing?
Louis Camilleri, the CEO of Ferrari, is also the chairman of Phillip Morris Ltd. So there you go.
8:15 they'll be nuts if they do that
Great videos! Can you make a video about racing tracks design? And what considerations should be made to design a "dream track" that is fun and complex. And if there are some regulations like max cornering angles, or max lenght on a straight line, or total circuit lenght, etc.
Recommended to me the day Leclerc had engine mapping problems haha
I know I would be more popular down the pub if I remapped my engine, but no the engineers know more than me.
How would they incorporate the 'party' mode settings? Is it just exclusive to the top 3 teams xd
I saw the AutoSport video and I said "Nein!!!" Open the Tubetube today and just like a crack addict needing a fix I kept repeating "where is it!!" Till I found.. SMASHED on the screen so hard my nail left a little mark on my plastic screen protector (don't worry it heals itself. It's like a gel coating so it will go away in an hour or so)
multi 21, Seb
Does the video have to go up on your channel after it does on autosport?

Chain bear has seriously enriched my F1 experience to an extent that I don’t think I would have found F1 to be as interesting as I do now if it wasn’t for the knowledge I’ve gained through your Chanel. Thanks Autosport for collaborating with CB for this vid.
How are there day-old comments already
Patrons?
Because this video was first uploded onto Autosport's channel
Patreon is how I got here a few days ago
MULTI MAP 21
Can you tell me about the software’s used for mapping?
Gentlemen, a short view back to the past. Thirty years ago, Niki Lauda told us ‘take a monkey, place him into the cockpit and he is able to drive the car.’ Thirty years later, Sebastian told us ‘I had to start my car like a computer, it’s very complicated.’ And Nico Rosberg said that during the race - I don’t remember what race - he pressed the wrong button on the wheel. Question for you both: is Formula One driving today too complicated with twenty and more buttons on the wheel, are you too much under effort, under pressure? What are your wishes for the future concerning the technical programme during the race? Less buttons, more? Or less and more communication with your engineers?
I actually didn't know about the rule that 100% throttle should amount to 100% torque. Thought they could dial the engine back and run a leaner mixture.
I guess if you have to fuel save, you could put up a map that maxes out at 80% Torque by 100% throttle.
As I understand it, they can do that, and the rule basically just means that the highest point in the torque curve needs to be reached when the throttle is fully down, so it's not "100% torque" as such, it's just to make sure there is a certain linearity in the torque curve, and it doesn't have peaks and dips in places where the teams might otherwise want them. Then again, unlike a diesel engine, which has a massive early torque spike and then drops off, a petrol engine will always tend to have higher torque at higher throttle inputs unless the mapping is messed with very significantly, so this could also just be a way for the FIA to guarantee "natural" behaviour of the engine.
+ISLAMATRON - Could be, which is exactly why I put the words "As I understand it" at the very start of the comment, to make it abundantly obvious that I wasn't saying it with 100% certainty.
Why in my notification it says F1 Bingo instead of this???
