expression pedals

I have a Mission sp1. LG. I Calibrated this pedal. It goes from 0 to 80% in the first few mm I move it and the rest of the movement does the other 20%... Is there a way to adjust / recalibrate this?
I also have a Boss FV 500H. This works fine...

Oh, reversing the polarity did the trick for the Mission!
The Boss, however seems to work better with a normal cable...
