i recently got a g25 wheel and when i want to set it up for lfs the wheel turning degrees does not want to work, in game i set it to 900* and in the profiler i set it to 900*, but when i go to i barely move the wheel and the ingame wheel/car goes flying the same way (i turn the g25 a couple degrees and in game it is already locked and i can still move my g25)

Happens sometimes to me, but when I alt tab and go back to LFS again it's fixed.
Also, go to 720 degrees since road cars are 720.
And why 2 posts?

Have a look here.-->> http://en.lfsmanual.net/wiki/Options#Controls

Read "controls" section...All you need to know

I have tried alt-tabing out but didn't help, this also happens to me every time has not once worked properly.

(im new to the forums and i didn't know what to put this thread under)

Have you configured the axis properly in the game first? If not, do so in the options, then it should work normally...
