adro 1083 Report post Posted September 2, 2020 anyone know if i can update my GM module which is currently a GM3 'low' module to a GM3 'high' module. Does it need coding like the lcm or can I plug it in and use PA soft to change the options? My end game here is i'm wanting to retrofit an M5 steering box but the servotronic unit requires a GM3 high module according to the internet. Cheers, A.
