I've got a logitech force feedback wheel but it doesnt centre properly. When the wheel on the screen is straight my wheel is turned slightly left. Is there anything I can do about this? thanks

Calibrate it?

Typical Logitech I think. If you recalibrate it and check mark the option to "Lock calibration" it use to help.
In other games I use to turn my wheel back and forth to the end in resp right and left before the start. It might help here too.
