Looks like I lied to you yesterday. My problem came back.
I ended up recalibrating the controller in LFS and the problem seems to be gone for good this time.

JoyToKey did the trick. I can't figure out how to make "Shift-xx" or "Ctrl-xx" work, but I can map enough single keystrokes to do everything I need.
Thanks.

I have a TSW Evolution Analog wheel with a bunch of buttons that I'd like to map to various funtions. As an example, in "Options - Controls", the "Alt-F4" button is described as "/exit" and pressing "Alt-F4" exits the game. Great - I can assign a wheel button to do that.

Is there a way to define one of the spare "Alt-F" or "Ctrl-F" keys to be "Shift-P" and then assign it to a button? I'd like to assign buttons to tire temps, race line, instant pit, etc. Unlike the Logitech wheels, I don't have a Profiler program to do what I want.

I just had my old TSW upgraded to the Evolution Analog USB version. When I first plugged it in I had the same problem. I took the cover off the pedal set, loosened the set screw on the linkage for the throttle pot A LITTLE and turned the pot shaft a VERY small amount in the clockwise direction. Now when the pedal is up, the pot reaches full zero. All fixed.
