I'm Looking for any info on how to switch between the modes in a Pro xp but can't find much information. I know Mode 1 is default but I can't figure out how to switch to 2 thru 4. I would like to make a tune with different throttle responses and boost levels. The only thing I can find is the Code 13 plug pin 18 with a resistance value to ground selects the modes but I'm not sure if that's true or what the resistance required for the modes. Any help would be greatly appreciated.
