As far as I know, there's a PDLCAL setting in the latest Factor software. (And if it's not in the one you have, it will be in the coming release.) If you're having trouble getting any expression pedal to map correctly across its range with the H9, what you should do is turn off the expression pedal auto-calibration feature and then turn it back on; this will reset the calibration. Then, you should move your expression pedal from heel to toe until you get the H9 to recognize the range your expression pedal moves across. Then, you should turn auto calibration off again to lock out any further changes to the mapping.
