TX Ferrari Racing Wheel

I just got Forza and this 458 racing wheel.
My problem: There is about a 30 percent dead zone on the accelerator pedal as I apply throttle, this has been verified by Forza 5 and the Thrustmasters control panel on my PC
What I have tried already: Disconnect reconnect, reinstalled Forza 5, downloaded new firmware, adjusted dead zones in game with Forza 5 settings, looked at control panel on the PC for the wheel to find dead zone adjustments and couldn’t find any.

Any ideas??

Thanks in advance for taking time to read this…

Moved to hardware

Same problem here, did you ever find a fix?
