G27 and degrees!

I'm having a trouble at DTM-Experience. When I turn the wheel, looks like the there are to much sensibility.

It's weird to turn.

The G27 and the car's wheel does not sync. I changed the degrees, sensibility but no satisfied result. Please, what is wrong??

When I turn, the steering stops but the wheel continues turning..... ??
Try change your Logitech Profiler settings to 360 or 540 degrees.

In-game, change the steering rotation to 360 or 540 to match whatever you used in the Logitech Profiler. Some prefer 540 degrees in this game, I prefer 360. Change the steering lock to 26 degrees. Make sure speed sensitive steering is set to 0. Set steering sensitivity to 50%.
