Black box to 0411 Swap

[GM Dude]

I have a 1996 GMC w / 4L60E looking to re-pin to 411 PCM. The 411 PCM is from a 2001 Chevrolet Astro Van with 4.3L and 4L60E. What are the steps I need to do when I start the re-programing process? The 411 PCM has an OS with 12202088, the credits for the 411 PCM has been purchased and benched tuned to disable the VATS. See attached for 0411 Astro van stock tune.


Any help would be appreciated.
Thanks for your help.

It might help to say what engine is in the 96 GMC.

youd start just like anything. Fnd a compare file for your whatever engine, and make sure the egine size, firing order are correct, then get it to run.
Follow the RUSSK idle conifg and you should be good.
after that, VE, MAF, and the PE with wideband.

If he put a stock L31 van tune in it, runs flawlessly like a stock L31 van does on an 0411 or a GMT800 L31 truck runs on a P59.
