Hello. I got problem with this wheel. When i'm driving it just jumps to left side a bit,and it happens time after time. Is this technical problem or I need drivers or some sort of settings?
I can confirm that this will not be a calibration issue. Many people have complained about the same problem and their wheels have been calibrated.
The Logitech Formula Force EX is a relatively old wheel now and as far as I can tell, the drivers haven't been updated for Windows 7 meaning that with force feedback on, the wheel jumps from left to right with some of the FFEX wheels.
In order to help counter this, I turned my wheel turn compensation up to about 0.40. Or just don't use force feedback for now if it annoys you.
