Hey guys I got a fanatec csr wheel and I have a few game breaking problems

1) the game seem to think that down shift and up shift is the same button so i can only either down shift or shift up not both

2) the steering is really weird, like it turn really fast with just a little twitch of a rotation I want the full 900 degrees steering

3) the center position isn't the center position of the wheel

I play other games just fine with the wheel like assetto corsa but this game just doesn't work well

1 - Are they the same button in LFS controls mapping?
2 & 3 - Calibrate your axes inside LFS, probably you have them locked, so it can't update the center to its real position.
