Ok, getting my but kicked on my vats issue I had on a 06 Saab 97x with the gm drivetrain, I could not get it to crank and I wrote the entire ecm and tcm, it showed being disabled, but still no crank and the security light is staying on, I tried and re wrote the file with tcs patch enabled and disabled a couple of times, but now, after I did a re write entire and disconnected the mpvi2 and reconnected, it showed no vin, so I closed the software and shut off the key, and re opened and the same, it did see the tcm, and when it opens, there is nothing in OS or the Engine info. If I open up the stock file and try to upload it, I get unlicensed vehicle. Please help if anyone else has had this problem or did the write go bad and pcm is now screwed? I also noticed there is no longer a check engine light during ignition on.
