[XBO] Accelerator to controller input off

Is there a way to balance controller input to the accelerator? Currently it seems the first 90% of the trigger pull only gives 10% of “pushing the pedal”. Then the last 5-10% of the trigger pull pushes the accelerator to the floor.

I’d like 50% trigger pull to be 50% accelerator. I play with drive assists off so maintaining traction with just the end of the trigger pull is extremely hard.

Also, seems to be this way, more so, on the higher end cars. Like 85% throttle = 0-60 in 30 seconds, 95% throttle = never ending burnout.
