Hmm. I've used a Logitech Momo and a G25 with LFS, and all I did was
install the drivers, calibrate it in Windows, then go the to the game
and set it up.
Other than making sure (in windows) that Gas and Brake are set up as seperate axis, all should have to do is go into LFS controls setup, assign
the gas, brakes, shift functions, and set the Force Feedback to your liking.
Depending on how many buttons are on the wheel, condering setting up two for the left / right view, maybe one for reset and one for pit limiter.
