Well I finally solved it.
You have to go into the SST profiler and pick the key you want for the wheel. Make sure to use the advanced command. For keypress, press the key, but press it a bit longer than a tap, I have .2 seconds in the profiler. Mark it as a macro.
This way the sim in game will pick it up. The ingame profiler will pick up the normal keypress, but ingame it won't register. A slightly longer key press will.
Hope this will help anyone that runs into the same issue.
