Throttle Linearity (UPDATED)
Whilst trying to drift(using my Logitech G923 with H-shifter) something struck me: by 25% throttle pedal press the WDT Nissan S15 was redlining. I exited out of the map, picked the Abarth 500, loaded up, and the same thing! I sat for a couple of minutes playing around with the throttle and I was able to fine tune the feeling down to feeling like by 25% press I was at 90% power, so I feel like 90% of my throttle is in 25% of the range and the top 10% is in the remain 75%. Is there a way I can smooth out the throttle so I am getting a realistic response from my throttle pedal?
UPDATE
After re-running the Win10 calibration program AND the calibration programs in AC, ACC, F1 2021, and pCars 2 it feels to me like at 40% throttle pedal press the cars tested are driving like I was at 90% throttle pedal press.

I've asked this my self once before and nobody answered, so I'm commenting here to see if there's an answer here. Also this isn't limited to the G923. it's a lot of the wheels and pedals. I can literally just put my pedal in not even 10% and rather than the RPMs climbing to a certain level it just straight up keep going til red line. Just slower. It's almost like the gas pedal is determining how fast the engine will red line and not actually behaving like a gas pedal.

Interesting. I've noticed this myself in the one month I've been playing. Would be interesting if there was a way or a mod that makes the gad pedal respond more realistically. ie; redline being at the upper end of pedal pressure

Glad to know I'm not the only one. It's been making trying to drift nigh on impossible.

No mod as far as I know to change throttle linearity, it’s not a common issue on forums etc either. Just need to adapt to it I guess, plenty of people successfully drifting in AC out there.

Try going into AC without content manager.
Go through the control setup wizard from start to finish.
See if everything is 1:1.
You can edit sliders to make stuff allign properly with your movements.

If this doesn't work then atleast i bumped the topic :)
Bump.

The issue is that WDT Nissan S15 has completely linear throttle already.

Modern cars have electronic throttles that adjust linearity based on speed and gearbox state so it >feels< more linear to the driver. It is the lack of this system on most (all?) AC cars that makes them feel off.

The redlining at 15-25% pedal travel means linear POWER, while what you probably expect is to have linear RPM response - which only makes sense when you are stationary.

You could technically mod the car to be smoother in neutral, but that would mess up how car handles while driving... i think the game has tools to solve this to some extent but it's a lot of work and with good enough set of pedals it's not a problem at all, so (afaik) nobody really dig into solving this.

So if you want "realistic" just leave it at default, dont mess with throttle, and assume that your car has custom engine tune that throws out all the stupid post processing chips, or has a straight up mechanical throttle linkage.

This problem doesn't exist just in neutral. It exists while driving and it's a problem I discovered that is happening in all my racing games. After re-running the Win10 calibration program AND the calibration programs in AC, ACC, F1 2021, and pCars 2 it feels to me like at 40% throttle pedal press the cars are driving like I was at 90% throttle pedal press.

Oh, that changes things. Open up pedals app and check if the green bar is filling up linearly as you press the pedal back and forth (you can size the app up, or use the one provided in launcher in control options to check with more clarity.

If it's indeed problem with pedals it's gonna be tough as such issues are quite rare, so the more info you provide the better chance of help.

Ok so after reading this thread, and believing what I also perceived to be overly sensitive pedal reaction. I spent a little while today checking a few different cars with the pedal tool showing and and to my surprise whatever pressure I applied to the gas pedal reflected accurately in game too. Just leave the car in N and press the gas pedal, 25%, then 50% then gradually work my way up to 100% and the green bar reflected all my pedal pressure perfectly. Maybe it was just a mental thing where we think the inputs are too sensitive in the heat of a race? idk, but thought I'd share my feedback.

It's not a mental thing, my pedals inputs are fine and game recognizes them fine, the issue I'm having is I can be in N,1st, 2nd, 3rd or 29th, gears be damned, if I press the pedal even 10% the revs will climb and climb and happily slowly climb til red line, the higher the gear the slower they go, but they don't stop, even at red line it just goes to rev out. But there is one things right in this thread, I want more control over the revs, like I have in my regular car. If I'm half gas my RPM's in my AE92 won't just climb to red line, they'll stop at around 4.250 rpm

Yep, that definitely doesn't sound right for the throttle to gradually just climb to redline when you only have 10% pedal pressure applied. Just wanted to share my own personal experience.

Has anyone found a work for this? Man this is killing me, Forza doesn't to this to my pedals, why does AC :(?

Did u find the answer? I’ve got same issue(

It's an issue in Kunos sims, AC Evo has the same: https://www.youtube.com/watch?v=0SlUlENAggE

At least that's what I assume you're referring to..
