It's ok for a couple of races but then it needs to be adjusted again.
Sorry for using this old post but I can not find anyone else with the same problem.
I created a post in the technical support, on the same subject. This has bothered me every time I click the XBOX button to do some activity, when I go back to FM7 several steering wheel items have lost their setting, the acceleration is 95%.
