Hi, when you say setup according to the manual, do you mean the wheel's manual or the LFS Manual?
Especially this in order to set up the axes properly.
If none of that is helpful, take a screenshot (ctrl + s - it'll be saved in /lfs/data/shots) of your options > controls > axes screen (when your wheel is at 12 o'clock position) and upload it here, so someone could spot if something was wrong.
