01 LB7 Locked pcm

If are using EfiLive, There should be an option in the V8 software to override the lock and flash over the current tune. I think you have to full flash it and it will pop up a message to permanently erase the current tune and put yours on it
$200 shipped back. Shoot me a text to my number in my signature if you wanted to have that done.
No clue until I have my hands on it. There's always some quick diag that goes into them before flashing like ensuring the serial comes back as a normal state etc.
I've only had 2 total that required repair/were junk.
(dumb) Question: 'back in the day', the only way to lock the LS1/LB7 ECMs was to change the seed/key pair to something custom... Did they change something to keep the factory seed/key pair but still disallow reading?

They put out an update that can override the lock and flash another tune over the current one. This was in response to many of the tuners leaving the business and people getting stuck. It allowed them to get their tune updated or restored to stock even though they didn't have the password (or seed). It doesn't allow reading. Only flashing over the old tune
FWIW, HPT hacked EFI Live code so it can read EFI's custom operating systems. I think Sometimes it can read EFI locked tunes as well, at least on the LS1B PCM.
They lock tuning from read access. You can lock the controller with a custom key overall but there are overrides for that in terms of flashing.
