Default What are my options with a locked PCM?
Here is the deal I have a tune from allen nelson on my 02 scsb, I Just bought EFIlive. I to start working with the PCM but it is locked. I can log alll day long I just cant back up the file or make changes. I have a stock pcm for a 01 2500 hd with 6.0 and 4l80, and I also have a 02 5.3 4l60 pcm. The truck has a LQ9 with heads and cam, and a 4l80 with a kit and verter. wHAT should I do to start working with the truck swap pcms? Which one? This tunning thing is new to me but I think I will pick it up just fine.

A full write "Should" work, though I'm not 100% with efi... Another option would be to buy another 02 PCM

you have to take it to the deal to have it reflashed with a tech 2 only way, or send it back to nelson to unlock it and set it back to stock.

All I did was have Allen send me an unlocked pcm. Still had his tune on it.

New pcm or have it unlocked by your original tuner are the only ways.

Tech2 nor a write entire will be able to unlock a pcm.
