I didn't have any problems at all. Did he have a battery charger hooked up during the flash! You have to use a 10 amp battery charger set on manual during the flash otherwise you could brick the DME. There was a guy over on the M3 Forum that had this happen trying to flash the TTFS SMG tune and Frank was able to help him out. If thats what it is call Frank and don't keep trying to flash it.
What exactly is it doing anyway?
