Unfortunately we just figured out we have to upload a different firmware to get our 10.5, 13.5 and 1 cell to work correctly.
First is this indeed the case and second what do I need to update the firmware?
I do have the new Revington Pro 1.1 programmer if there is a way to use that?
Unfortunately you'll need the old Pro LCD box and the proper update software installed on your computer to change the software on the GT series speed controls. Maybe try asking around your club, if there's anyone who's ran Speed Passion there, they're bound to have one around.
