Not sure if this is where to come to, but here we go. I currently bought a Jet DTS for my '96 corvette. It has been tuned before by the PO. And I wanted to "back up" the tune before making the swap to obd1. When I try to read the PCM, I keep getting the same error. I tried using windows XP, 10, and 11, to no avail. I've come across a few articles stating that the pcm is fried, but possibly locked. Any ideas? Thanks
I believe that the PCM you have is essentially the same as the one I have been working through. So far I have not used 3rd party software so issues relating to Jet DTS are nothing I can comment on. If you have an ELM327 cable OR are willing to build the cable I wrote up, I can give you a series of commands to find out the problem with your PCM. Additionally, I will soon post on software I created to read both E and TSides of your PCM. Anyone with a tune installed is dependent on the software the tuner wrote/changed. This can include subtle changes that can prevent reading.
Worst case if your PCM has lost it's FLASH content, I posted a method to recover. Look for posts referencing '97 Camaro in the GM EFI section.
Do you plan on installing OBD1 software on your OBD2 PCM?

since it's a commercial product you paid money for, and it's not working, why not ask the people you bought it from? if i paid money for something that was brand new, whether it was software or a toaster, that's what i'd doQuote:

Is this still something you are working through?Quote:

Have a look at

I posted an app which might work for you.
