I posted this in Scan And Tune with no answers today, so I'll try it in here?
I just bought a Techline Tech 1 scan tool from E-Bay. It came with 1 cartridge for 86 to 92 GM ECM. I have a 93 Corvette, when I ran the on board diagnostics it came back as a 92 ECM (The diagnostics that read back from the speedo) So can I use this cartridge on my car? If the software is not compatible will I damage anything by hooking it up?
