i've only configured from the control panel of the windows/game controllers /advanced the pedals to be separated... so i can press brake + gas together...and the wheel at 900 degrees.... i haven't touch anything else at the wheel's configuration...after this i only change the game's configuration..
P.S i'm not playing LFS yet,i have just tested it... im playing bmw m3 challenge...but the pedal is the same in all games (GTR 2,bmw m3 chall., lfs , rfactor)
