Possible corrupt PCM?

[darky82]

I don't what I've done wrong and how to fix it.

I was running a EFI live tune 1290005 and editing it in tuner pro and things were fine.

I tried to change to Ls1 boost OS V2.1 and wrote it to the PCM and here is where my starting issues came about so I swapped back doing a full clone rewrite but PCM hammer could not unlock so i had to ground the pad to get into recovery mode.

The issue I'm having is that the car will start and than stall instantly, fuel pump does a short prime or does a short prime twice, sometimes does not prime at all.
But if I keep trying 10+ times to start the car it eventually starts and runs fine till next start up.

I have tried changing the seed, key, bcm code in tuner pro thinking I have stuffed that up but I doubled check from the untouched base EFI live tune and it was the same values.

I'm thinking somehow I have corrupt the PCM?

No idea, if I were you i'd look at the initial backup of the base tune bin file in universal patcher and make sure you see the vin number which means the paramater block is in it, which also contains security data, and then do a clone write back in to the pcm. And then see where you are. If you are not back where you started then you have a new problem.
