First, neat game you got here

I bought it to teach a family member to drive and it seems really useful and realistic.
My Problem:
I am using a Logitech Driving Force GT wheel with City Car Driving. The brake and accelerator are too sensitive (100% when I only press about 33% pressure on the pedals). Logitech's own configuration tool registers the sensitivity as ok. I think the problem is with some configuration in the game.
I tried messing with the pedal sensitivity in-game settings but those are apparently for the keyboard only. I also messed around with linearity/dead zone settings but after spending a lot of time tweaking them I realized that won't solve the problem.
I'm not experienced with driving games/wheel configs, so I'm hoping someone here has a solution. Did some searching but didn't see any answers. Is this a config problem or a fix for a future update?
If there is a way to hack files to make it work i'm ok with that too.
Thanks!
