Has anybody gotten the pinout?

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.

Can the 0411 operate as a speed-density system, or does it have to use the maf? Does the 8.1 use a larger maf and throttle?

411 can run in speed density mode. Not sure on maf, but there have been larger maf and throttle bodies installed using 411 ecu. Will need to tune appropriately
