Generally, use AC wheel wizard and let it work its magic. I would suggest adjusting the specific car FFB to avoid clipping (grey bar in pedals app turning red) and that's basically it in AC.
If you want to get more on the advanced side of thing you can try tweaking the ffb effects values and the gamma settings. But I recommend reading what each setting does before tweaking it.
If everything goes wrong, you can just start again from the default preset
