Logitech G27 Problems

I've been trying to adjust the degree of rotation on my Logitech G27 wheel to make steering a bit more realistic since my wheel doesn't usually use full rotation. Only half. After I adjusted the rotation degree steering worked fine but my clutch was messed up. The clutch seems to slip. In any gear if you use full throttle the engine goes to red line and the car won't move until the throttle is released. Then once I stop even if the clutch pedal is down the car still stalls as if the clutch didn't work. Can anyone help me?

 

I've never had this problem with mine, but do you have the Logitech driver software installed correctly? (I believe it's the Logitech Profiler)

 

Perhaps you have the clutch AND the throttle assigned to the same pedal? There's not much else I can think of that would cause this.

Edit: Come to think of it, that shouldn't be possible, but it's worth checking.

 

I have just bought a Logitech G29, with pedals and shifter and I had the same problem. I just recalibrated it in the windows control panel and now it works
