Not specifically, no. I can tell you that this game has a few control issues, and the FXT wrapper fixes... some of them. if you can, only plug in you G29, no other controllers. I would then try different combinations of rebinding controls in-game and in the wrapper, calibrating the wheel both in-game and in windows, and enabling or disabling the FXT control override - i never wanted to use it as it won't let you gear-drift.
While this mod is awesome, i prefer OR2 SP SDX in Teknoparrot, myself.
