Pedal calibration not working

I set my clutch to 50% in calibration. After saving, it does not take effect. Pushing clutch 50% should register as 100% in game. Game setting does not allow max dead zone. Only min dead zone can be applied. Can anyone help?

 

The pedal calibration in-game only checks if the pedal uses a positive or negative value for the axis. It is not meant to allow for calibrating the upper deadzone, you need to do this in your pedal driver/software.
