12200411 PCM swap for 1996 to 2000 GMT400 trucks

[damtruck98]

Since we have a new 96 up Vortec subsection, I thought I would make a new post.

The 12200411 PCM can be installed into the 96 to 2000 GMT400 trucks simply by repining the PCM connector terminals. The wiring is slightly different between the 96, 97, and 98 to 2000 trucks. The 0411 PCM has a much faster processor than the Black Box PCM and has dual timing tables. There is also more support from the tuning software companies for the 0411. EFILive and HPTuners both offer "Custom Operating Systems" for the 0411 to support boost and or nitrous. The swap can be completed in about 2 1/2 hrs and is fairly easy to do. If anyone is interested in the swap just PM me your e-mail address and I will send you a copy. I will not post the files to the web.

I think someone needs to edit the original post. At the top.

I don't know that there would be any higher chance of people reading that considering there is a sticky thread DIRECTLY BELOW THIS ONE that has the answer they seek.

Connect a scan tool, figure out what's wrong.

If you can't troubleshoot the current system, it's not likely you're going to fix it by making things more complicated.

Take the diagnosis one step at a time, and understand that you likely have multiple problems. Being able to connect a scan tool and read data stream is invaluable, and far better than just reading trouble codes. Did you check your sensor outputs, or did you just pull codes?

Has anyone had their cruise control stop working after the 0411 swap?

Not on the 2 I've done. Any other quirks or just that?
