I just got the g25 and now whenever I move the wheel a little bit it turns all the way in lfs and force feedback kicks in.

Any ideas?

Make sure that in Options > Controls > Axes/FF, the option "Calibration Lock" is set to "No". Then actually rotate the wheel lock to lock. You might also have to press each pedal fully to calibrate them correctly.

Hmm that kinda fixed the problem
What should the wheel compensation be?

Can someone post a screen of their setup in LFS? and in the Profiler

Wheel turn compensation should be 0, for a profiler screen look here.

be sure that your rotation degree in the game is the same as the control panel

Depends, if you set WTC to 1.0 and the steering lock to 720 degrees in both the profiler and LFS, you will have correct lock in every car, but only get FFB lock stops in the road cars. If the lock stops are important to you, and you can be bothered with the hassle, then you need to change the profiler lock everytime you change car.
