HyperTech Hyper Screwed me
Think... What does the HPP lock to? The VIN.
What does the PCM have in it? The VIN.
What can a dealership Tech2 with the GM SPS program? The VIN.
Using a Tech2, program the offending VIN in to a PCM. Then hook up the HPP, "Return To Stock", then use the Tech2 to restore the *real* VIN and stock program.
If you have a tuner program in the PCM, it will be erased by this method. The Tech2 can only reflash to stock.
You must also have the right PCM model year to do this.
Err, you also gotta have a Tech2 with the SPS, or the Ease programming package (at $1800). Which is my problem. I don't have either of them.
Last price I heard from Hypertech to do this was in the $350 range.
