VKB-SIM

I've been trying to program the radiator and fuel mixture functions to my En1 and En2 encoder wheels, but they were not taking. Eventually, I did get them to work. Don't know if it was a re-calibration or what, but now the two encoders offer responses in the game. The issue is the responses are too fine. It takes a lot of movement of the wheel to get 5% adjustment in game. Is there a way in the VKB calibration software to make the responses coarser? I've never used the software tool before and it looks pretty intimidating.

Please show screenshot of your encoder settings. Button mapping wizard and axes - physical and logical. My encoders work fine as trimmers, radiators etc.
