Force Feedback was waayyy too high to drive properly with my DFP. And I came up with another idea: Mapping MouseY for accel/brake and MouseX for steering on my notebook. That was more horrible than I exspected
this was fun i tried to move the wheel with my forehead, but ff was so strong my forehead just slipped off so i had to reduce ff almost totally. the 2nd problem was the screen, since i only managed to read the 'samsung' logo on the bottom of my tft so i ended up holding the wheel in the air. still, when i turned it i saw body of my momo only, so it was kinda fun
edit: also had some difficulties with using my chin to shift :P
Put your forehead a bit right of the center of the top of the wheel. Then tilt your head until you can see the screen.
For shifting map shift up and down to buttons on the front of the wheel. When you need to shift let go of the wheel and give the shift-buttons a Zidane-hit.
Oh, and reduce force feedback to zero.
