Hi Ali,
Unless there is something new available on more recent controllers, none of the available settings will alter the direction of the PAS operation:
Dependant upon which pedelec sensor you have, it may work with the magnet ring fitted fitted on the non-drive side.
My MP4 powered "Wheelie Machine"
(the only bike I currently have with a pedal sensor installed) does have the sensor fitted on the non-drive side:
Make sure that the arrow on the magnet ring is pointing in the same direction as you normally pedal and you may well find that the PAS will work regardless of which side of the bottom bracket the sensor is mounted on.
