LS2 Edit???
I have a 2005 Pontiac GTO that was Tuned by Pro Auto Tech with LS2 Edit. I want to return the car back to stock and sell it. The dealer tried to reflash my ECM with a stock program from a Tech 2, and that wouldn't work. They then tried doing it with the Pass Thru method, and that also failed.
Pro Auto Tech has been sold to Rev Extreme, so I went to them to get my ECM capable of accepting the stock tune. They were able to find my "stock" tune on Ron's (The former owner of Pro Auto Tech) computer. After loading that I went back to the dealer, and they still cannot Reflash my ECM with a stock GM program. What steps need to be taken, to get a stock GM program installed? The dealer, and REV Extreme tell me I need to buy a new ECM. Is that true?
Thank You,
Tony

Before I had my car tuned by RevXtreme, I did some research and if I remember correctly, i recall reading somewhere on the Forum that once the computer is tuned with LS2 Edit, you can't retune back. I later found out the the current tuner there uses HP Tuners and I would no problem with that if the dealer decided to flash back to the OEM program. However, in my case, I had installed a Chevy 2005 3:42 ratio with my A4 transmission. Chevy doesn't have a program for an A4 with 3:42 gears because that option isn't sold that way originally. I will always need a tune so the car runs correctly. I could change the gears to 3:15 but hey, I'm already thinking of changing to 3:73's! Hmmmmmmmm?
You may need a new computer because of the LS2 Edit.

Make sure the shop has turned off the auto ECM locking feature. It is set by default on LS2 Edit, so flashing it again will result in the same problem.
Cheers,

Bad news. Read post 60 thru 64 on this thread.

I'm getting ready to have my car tuned by Mike Norris who uses LS2 edit, so I'll be in the same boat. I was going to buy HP Tuners and learn myself but after Mike tunes me I'll be locked. Maybe LS2 will change that "feature" in the future.
