F1 2014 Throttle Settings on Xbox 360 Controller

[M Theory]

I thought CM were going to make it possible to adjust DZ, linearity and saturation on controllers this time. I can't find the ability to do so on the Xbox 360 version of the game.

I'm all assists off and the throttle control in particular is so sensitive, it's almost like an on off switch. Maybe 1 or 2 mm. I've tried two controllers; the wireless is slightly better than my wired controller for the braking. Trouble is, wired is better for the steering. Is there a way to change these settings on the Xbox 360 version?
