You shouldn't have a BRF setting at all if you don't have a load cell pedal.

Thanks @timekiller001. Just after posting I just questioned myself - what would be limited in potentiometer based pedal. On the other hand I started to have issues with calibration/working of pedals since I played with BRF.
But most likely it is a RJ cable related.
My gas pedal is sometimes not working or being calibrated only downto ca. 50% of the range.
So far different/random actions solved this - different each time: reconnect, reboot, recalibrate, etc.
So still looking for ultimate diagnose.
