DiRT Rally 2.0 G27 pedals issue

[XPheco]

Hello i have problem after last patch: my acceleration and brake pedal have only 0% or 100% nothing between this two values it doesnt matter how much i push pedal if i just step on acceleration pedal and move it for like half centimeter it revs rpm to max. Same in calibration when i step on brake or acceleration pedal it moves instantly from 0 to 100. Clutch works fine, in another games like dirt raly 1 it works just fine. Do you guys have some ideas how can i fix this problem ?? thx for answers
