Yes, i've send my controller to MGM to update it with the new 3.21 SW but it continue to cut in "cutoff mode"
I'am to download the 3.22sw but not sure if this was fix the problem.
Anyway, i exactly know what i'll do at the track, i'll program it on "race mode", like that i'll don't have any problem with cutoff.
Anyways, at the track i only run 5 or 6 minutes at time, and i re-peak my pack each time.
