As the title says... Completed my most recent tunercats tune, finished loading, said complete, like it has so many times before. Only this time, when I went to start the engine and do a test run, it just sits and turns over. To add to the excitement, when I tried to plug back in again, I get an error that the PCM cannot connect. I need this fixed, or a replacement ASAP.

I have a spare that I keep around, programmed and ready to slap in. Assume you have a known good back up .bin file, if not let us know, what you need. An A4 requires F-body '94 .bin code, M6 can use F-body '94 or '95.
