My plan was to load the stock .tun file for my 1998 Corvette 6sp.. After verifying my operating system was a *****200 type, using the Scan Tool, I downloaded 19980200 file from Holdencrazy.com. I loaded .tun file into EFILive Tune, then mistakenly selected "Program PCM with currently loaded operating system and calibration" instead of "Program PCM with currently loaded calibration". I saw program communicate with PCM, it completed erase PCM cycle, but never started loading any program. It kept saying something, but I can't remember; it was something like retry.
Currently when I try to load either the Calibration or Operating System, EFILive says. "Preparing PCM for reflash", then next line says "PCM may not be secured - did not reply to seed request" It goes through four retry's then gets a "Bootloader rejected" error. "Reason: No response from PCM"
Mistake was mine for selecting to load Operating System and .tun file. I really only wanted the .tun file. Any idea's? Thank you in advance
