Need info on flashing 01 5.7 vortec 0411 to run a LS

[12ramhemi]

I bought a 0411 pcm p01 a few years ago. It came from a 2001 express van 3500 with a 5.7 vortec. I am wanting to use it in my 95 jeep ls swap. I have a 2000 5.7 ls1 short block with 2000 5.3 top end, sensors and stand alone engine harness. With a th400.
What do I need to do for the 0411 pcm to run this setup? I've read it has to be unlocked and registered, that's 2 credits. Then you have to change the vin and upload the LS o/s . That's another 2 credits... I've also read that you only need to license it the first time and there is an option to change it to the ls configuration.

Some one please help me out?

It'll take 4 credits total. You'll use two credits to unlock your PCM, then two more to flash it with your LS1 file. I'd recommend using a 2002 Camaro file. Since you're using a non-electric auto transmission, you can just flash it with a manual transmission file.
