The reseting seems random to me as it stands which is fustrating.

Also fustrating: my previous ROM was a rock star for months pegged at 0.9ish - 1.0 all the time. Then at 4:30 am on my way to the road course all excited to try out the tune... my IAM drops to 0.28-0.33 cruising there. So now my ecu doesn't like the calibration?

I figure ok maybe it is low rpm stuff that it doesn't like so I add half a can of Torco octane booster (brings it to ~95 octane) and drive it around the road course (high load / high rpm) 7 laps. IAM is still at 0.33 even with the higher octane...

It was time to re-flash the ecu with the same tune and start from a IAM of 1.0. Guess what? 7 or so laps later and it is 0.96. Happy again...
