Ok i was doing a A4 to M6 swap in a ls1 car, got everything done and the car started and worked great. I went in and started turning off auto DTCs and reflashed and the car wont start just turns over, the fuel pump relay is making a constant buzzing and the fuel pump is constantly running with key on engine off. Shouldnt it just prime and stop running? Anyways I get get the the OBD2 to respond either it keeps saying "make sure cable is conected and key is in run position... All my fuses and wirring look fine anyideas? I have used my hp tuners 100 times or more on this car.. Im stumped I think it has to do with vats but I cant figure out why the fuel pump would be acting this way just from diff tune.

I think you need to find a M6 OS and do a full flash. I know you have to do it the opposite way. Going from M6 to A4. Bill can probably verify here.

Depends on the pcm, there are 3 different LS1 pcm's so it could go either way.

Segmented files don't need a write entire from my knowledge as long as the os id is the same.

Single segment files do.

Its a 2001 trans am ws6 and I cant check for DTCs because the VCM will not respond.. everything is getting power and I know its not my software because it works fine on my truck.. IDk why it wont respond, i really screwed it up.. I have power to the dlc, cig lighter, getting fuel to fuel rails fuel pump is still coming on and running non stop with key on. Im goin to replace the pcm today because I hooked my compuetr on another 01 trans am and it did the same thing.no start, fuel pump constantly runs, fuel pump relay buzzing... what did I do to the pcm?

Try to flash it back with your original tune. It may go into recovery mode and save itself. If it does, go find a stock M6 file for your year, and do a full flash and swap over the vin, and relink VATS. Then you'll have a starting point for your M6 tune.

If you need help, send me your file. edcmat-l1@msn.com is my email.

That was my plan but when I try to reflash it the throws the "make sure the cable is connected and key is on" error.. Everytime. So it won't let me do crap

Check make sure you've got power to the ALDL. Other than that, you may be screwed.
