@@fajaradi1223 That too, but it's only really bad in the city. The heat bit is funny though. If you don't have a/c, it's summer, it's raining and you have the top up, you can feel the cabin warming up when passing a truck or going uphill.
I genuinely thought they were going to pitch an idea where you only have a brake pedal and when you let off it accelerates (like those terrible mobile racing games).
Same, would've been weird like if you could tune the ECU to move off at 80% throttle all the time, then you do passive burnouts in bumper to bumper traffic
This is basically opposite of the "one pedal mode" that actually exists on recent Leaf cars and some other electric cars. That mode "defaults" to maximum regenerative braking and stepping on the "torque request" pedal progressively reduces engine braking and then transitions to actually adding power
Jason: "Your car, like every other car in production today, has a by-wire throttle" Me: looks around at my aging fleet of drivers and suddenly feels very dinosaur.
That is why I enjoy my '75 Jeep CJ-6 that has both hard linkage throttle and clutch. I hate chasing sensor related gremlins that infest anything built in the last 30+ years.
Yep I like my dinosaurs I got a 97 and a 62 in the shed both are void of the brain boxes only cables rods and linkages Hell the 97 will run without a battery once it's started
This reminds me of Iain Tyrrell showing how to restore ~30hp from a classic Ferrari - he just corrected the two seperate throttle cables that had extended over the years.
Jason, you're killing it with this unique content. I'm learning way more than I ever would about stuff I've never given two seconds to think about. Please keep it coming.
Not gonna lie, that was a great video 🤐 Never thought of what goes into drive-by-wire, still, would never wanna get rid of my mechanical throttle on my S2000 🤓
Jason please whatever you do don’t stop making these series man, I’ve been around cars for ages but I wouldn’t be able to explain things like drive by wire so well like you did.
If there's anything I've learned from watching MCM and Skid Factory, it's that e-throttle was one of the best developments in engineering that reduced mechanical complexity. I've been having a load of issues with the shitty idle control system and vacuum-operated cruise control device on my 91 Miata. Hunting idle, hard starts, vacuum leaks and coolant leaks from a spaghetti of hoses are all problems e-throttle has solved. Once I go to a standalone ECU setup, I'm definitely going to figure out how to retrofit e-throttle.
Now there is active servo control of the wastegate on turbochargers as well, then a significant portion of the throttle mapping can be selecting boost based on the throttle pedal position while leaving the throttle plate open.
This is the best show ever. I can’t be the only one who wants to see more technical car content thats delivered in a funny way with good production value. Keep it up!
@@anthonyt4981 i'm not stalling, there is a difference. In one of his videos where he passed incorrect information about needing to upgrade existing parts and spending thousands of $$ on a car when you have to add a turbocharger. Talking about how manufacterers have to upgrade this and that and that just to accomondate a turbocharger to an engine which is far from the truth. Many people add turbos to their car and maintain oem parts. He said this is the reason why affordable sports cars are not turbo. Which again is incorrect, you CAN add turbo and not pass that $10k to the customer.
@@ACommenterOnRUclips well that wasn't one of his know it all videos. it was his brz video. I get where you're coming from, but it's kinda reality though. Hard to describe in a short amount of words, but that's how car manufacturers see fit. It's not Jason Cammisa's word and opinion, it's the industry's. he is just relaying it to us viewers.
The problem with these “torque request systems” is the same complexity that makes them so impressive on paper. Because they are constantly recalculating, they are constantly readjusting to produce max efficiency at the expense of predictable (I.e linear) and responsive torque behavior. As a result, when I drive JLR’s new Ingenium engine, modulating speed with the pedal becomes almost impossible. While maintaining steady pressure to the pedal, the car alternates between too much and too little power, making it easier to just stick with cruise control. Meanwhile, when I drive Porsche’s N/A boxer 6C engine there is granular modulation and driver inputs are transmitted more appropriately through the drivetrain. At the risk of sounding way older than I am, high tech isn’t always better.
I like anything-by-wire. I'm even developing a cook-by-wire gas cooktop. Improved fire safety and far more precise temperature control are some of its benefits. 6:10 aaannd that's my jam...
Fantastic explanation. I wish more people would understand these things. Now, speaking from an enthusiast point of view, I’m very thankful I still own my car from 94. The difference between cable and torque request is very noticeable. Absolutely no lag or “I’ll think about your request and raise you slightly less throttle”. Give me cable pedal any day! The only electronics in my 94 is the ecu to manage the engine itself, and the abs on the brakes. That’s it. Everything else is old school. 👏🏻 Driving the 2010 daily, I’ve got to hit the torque request pedal extra hard to give me the proper revs for a downshift. Gotta turn off stupid tsc as well. Every time I fire the car up. Thankfully it’s just 1 button. Give me the good old days any day of the week. 😎
I drove a 32 ford model A the other day ,it sorta drove like a old tractor. But I was controlling everything I could even adjust the spark timing while I was driving.
The comments remind me of all the old people complaining about how kids can't work on stuff, and then complain about how things are too complicated for them to fix themselves 😂 "Kids these days are lazy!" they say on their phone as a 25 year old is fixing their car for them. I'd rather have a simple cable too. But, well, things change. Even my 25 year old vehicle is electronic control (diesel).
Another potential benefit to throttle-by-wire: Cylinder deactivation in a car with individual throttle bodies. Who needs a complicated valvetrain when you can simply keep that cylinder's throttle valve closed? This also allows other cylinders to open the throttle valves further (because this will put a higher load on each of the remaining cylinders), to increase economy. And it's not a toggle. It's not "8 cylinder , 6, or 4 cylinder." It could be any number of cylinders that get deactivated. It could be used by the engine computer to deactivate cylinders that it has detected a misfire in, in order to save the engine, catalytic converter, and environment.
Not always. For example modern Porsches leave it open when driving in sport mode to keep the turbos spinning fast, so you don't have lag when you get on the power again.
The problem w many current manuals is that they come w rev hang and unpredictable torque request pedal response. It’s like getting a steak w a plastic knife and fork.
I was expecting another condescending Cammisa rant about stuff most car-guys already know... but, I actually learned something this time... a whole lot actually!
These videos are brilliant. I'm an automotive engineer with EV and transmission calibration experience. You're spot on with the torque request pedal lol.
Very good video... Even I learned some things! Which... I know you don't know me Jason but if you can teach me something about cars, that's impressive. One thing you neglected to mention is emissions. One of the primary reasons car companies started to do electronic throttles is to make the lambda fuel ratio adjustment PROactive instead of REactive. If you have a cable throttle, and you stab on the accelerator, there is a brief moment where the air flow sensor hasn't noticed the increased airflow yet, and a moment where the mixture leans out before the exhaust makes it to the oxygen sensor and tells the ECU that the mixture is lean. This may only be half a rotation of the engine, but you get a little burst of unwanted emissions. Suddenly lift off, and there is a brief moment of rich mixture. More sophisticated throttle position sensors (not just idle/middle/wot) improved this, as the computer knew what position your throttle was actually in, but at that point you're halfway to drive by wire already. By letting the computer react to the torque request pedal, and do the throttle opening in its own time, it can maintain the appropriate air fuel ratio continuously, regardless of how violently you stab or let off the go pedal.
Jason I agree but I would just like good throttle response and no rev-hang! Haha. I know that is very much possible with a non-cable setup, I would just like it to be tuned that way.
If I wanted the computer to do everything for me, I wouldn’t drive mostly older cars with manual transmissions (and manual transfer cases in some of them). This tech all works in a lot of cases, sure- but part of the fun is doing it yourself. Shifting manually, controlling the throttle, trying to find the limit of braking... it’s hard to do that with a computer holding your hand and saying “now now Timmy, I know you want to go fast, but let’s do this other thing first okay?”
Easiest way to think of it (IMO) is that any resistance in the intake tract (e.g. really dirty air filter, kink in intake tube, or closing of throttle) will definitionally increase pumping losses and therefore hurt volumetric efficiency. Part of the benefit of a diesel engine vs gas is diesel has no throttling losses. Throttling in combination with the energy expended during compression stroke (and general friction + load of valvetrain) results in engine braking off-throttle, which naturally is less strong on a diesel (I understand this is in part why the Jake brake exists, to further improve engine braking via pumping). The effect of compression on engine braking would be greater on a diesel due to high CR, but there’s no throttling losses. At least this is my understanding!
It also helps to have a steady percentage at throttle which improves fuel consumption like the ability of no engine braking. Much greater than a cable but i still and always will prefer the cable lol.
I guess that's what Infiniti calls the intelligent transmission in my car because it supposedly learns your driving habits based on multiple data points and usually hands you the correct gear based on speed, the amount of "gas pedal" requested along with how fast you requested it.
Thank you so much for creating and sharing this content! Ironically my degree taught me none of this. Kudos to Jason for explaining it all with such flair. 💯
You only need to fix a ecu controlled fly by wire car to learn why wire throttle controlled cars are still so hot in the market. Cost of ownership. More electronics = money pit.
Lots of cool additional info that even some of us "gearheads" didn't think about before 👍 Keep up the great content. P.S. "E-throttles" can also help with packaging, since you don't have to route a cable and worry about bend radii.
@@mry82 no, a 20 year old vehicle does not have steer by wire. In fact, no Prius has had steer by wire. All Prii have had brake by wire, though, so I guess you could call the brake pedal a braking request pedal
@@aspecreviews p.s. thanks for correcting me. I know some people are sensitive about these things, but I would rather know the truth! (also, if you already saw my last response, I edited it a bit, lol)
Except cruise control you can do all of the stuff (mentioned at 1:30) on a traditional cable controlled throttle by controling ignition. Have a look at motobikes. Most of them have cable throttle and still have traction control, rev limiter, idle speed control etc.
Ok, Jason. Thx. I always knew that I feel how our N/A cars "get lazy" after me wife is driving them. Now it makes sense because she is just rolling in high gear and then when I get them they are all ECO and Priusy and I swear for two straight minutes they are lazy....then adapting to the maniac behind the wheel waking up
Another great video. As high tech as all this new stuff is. And as cool as it is. I prefer my linkage of my 67 390GT Cougar or the cable of my daily driven 86 Bronco. (Which its only issue is pathetically low horsepower)
I must admit, I didn't really understand what Jeson Cammisa was explaining in the first half of this video. But by the end, I understand why having a Porsche 996 with a throttle cable, makes it one of the last analog Porsche 911's.
Every single driver controlled operation on a car is not ( and hasn't been for some time) switched on or even controlled by the driver . We request and the subsequent control unit decides if we can have it.
Drive by wire is nice and all, but what about that nasty rev hang? even if I lift before shifting it takes seemingly an eternity for the revs to come down when shifting my 07 tacoma.
I've always hated on throttle by wire but I admit, I never once considered most of the points you made. I can definitely see the overall benefit now but it would be nice if you also included a few of the things you lose when ditching the physical connection with the throttle.
I have a little Fiat 1.4 8v for a daily, and when I ask for the torque resquest pedal I can hear the car ECU mocking me “you are wasting your time bambino mio”

You don't request torque. You request rpm and then you move on those little engines 😁

Entertaining, straight to the point, and I learned a few things.
3:30 that is really fascinating and definitely deserves a separate video!
Easiest way to think of it (IMO) is that any resistance in the intake tract (e.g. really dirty air filter, kink in intake tube, or closing of throttle) will definitionally increase pumping losses and therefore hurt volumetric efficiency. Part of the benefit of a diesel engine vs gas is diesel has no throttling losses. Throttling in combination with the energy expended during compression stroke (and general friction + load of valvetrain) results in engine braking off-throttle, which naturally is less strong on a diesel (I understand this is in part why the Jake brake exists, to further improve engine braking via pumping). The effect of compression on engine braking would be greater on a diesel due to high CR, but there’s no throttling losses. At least this is my understanding!
What an education on fly by wire torque request pedal! I had no idea on the benefits.
Makes sense now considering Cobb’s Accesstuner software maps the throttle pedal as requested torque. Never knew that before.
It also helps to have a steady percentage at throttle which improves fuel consumption like the ability of no engine braking.
Much greater than a cable but i still and always will prefer the cable lol.
Torque pedal is catchy and works for EVs, too. Nice!
