Hi, newbiehere.... I have a 96 sierra I want to do the 411 swap, I have a ecm from an 04 yukon. Will it work? Thanks

Not with the distributored Vortec engine. I would work a Gen3 engine.

Hey Lextech I have a 96 that had a 4.3 in it will this repin method work for it as well? I need the spreadsheet if possible email [email protected]

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.

Jeff, the '02 0411, 5.3L and IPC into my 99 Denali L31 is well underway but I have questions:
On your instructions you say to omit/not use C1-59 YEL 710 Serial Data to BCM. If I go this route, will something not work correctly? Can I connect this circuit to Class 2 Serial Data on the DLC, BCM or IPC? Please advise...

I have a dumb question.

Is the 411 repin different if your running the factory 350 vs doing an LS swap? Meaning would the pins be relocated to different positions depending on engine used?
