I've been doing some more looking at the profiler. I have a similar odd situation: in my case the steering lock is correct for each car but the Overall Effects Strength setting in the profiler is ignored. It's not using the Global Default settings either. If I run the logitech profiler (5.10) as Administrator then the Overall Effects Strength works again, but the steering lock stops working in-game and is set back to 900. This sounds very similar to what you have. I tried uninstalling the Profile, deleting the G27 from devices, running 'WheelDriverCleaner.exe', and then re-installing but with the same result as above. 1) Run as admin - I can adjust the wheel strength from the profile but have to manually adjust steering lock 2) Run as normal - can't adjust the wheel strength but game adjusts the steering lock automatically. I can also shut down the profiler and AMS2 will behave exactly the same as 2) above. There must be a setting somewhere that windows is using hidden somewhere. Not sure this helps you but might give you some further options to look at. Have you tried launching AMS from the Profiler instead of from Steam?
