Is there any way to have a variable parking brake? The only thing I've been able to do in game is either a hundred percent on or completely off. I'd like to use the right stick on my controller as the parking brake for drifting and other purposes. I have the dead zones set so when the stick is centered the parking brake is off and when pulled fully down it's 100%. However pulling the stick down seems only to toggle it. I was looking at xidevice.diff in input maps but can decipher it. How do I set the right stick to variably apply the parking brake?
