I have a turbo 1997 corvette that pretty much has all performance parts in it ( to keep it simple). I can elaborate if needed. Anyway I decided to re pin to a newer style 411 pcm. I now have a cos installed 3bar. If theft is disabled it will run but when I try to do a vats relearn it wont stay running longer then 5 seconds and shut off. Basically what I did was run a check on pcm, then checked vats relearn with 1 ignition cycle. Of course after I changed the theft parameter to class 2 for corvettes. Once flashed it will only run for about 5 seconds again. What am I doing wrong?
