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.

Does repining vortec truck harness terminals into 0411 c1 & c2 work with an Ls motor?? Do you just change the ls connector pigtails?

@Lextech can I get the spreadsheet for a 96 2 door tahoe 4x4 with the 4l60e?

Jeff or any one
Have you used HPtuners with after doing a coil over plug swap , Used the Cam offset PID to set your cam sensor.

Tech support @ HP tuners is telling me once you go COP you cant see the cam offset Pid . I find it hard to believe the ecm knows the difference between you adding those 10 extra wires for the coils or using a distributor cap.

Sorry. I don't own HPTuners

Correct me if I'm wrong but isn't the camshaft position sensor on the distributor housing? So when you go COP, the distributor gets removed, so the CPS is no longer available, unless you leave the housing back there, in which case the PID should still be available to log (it is on my HPTuners but I don't know what to do with it lol - but I'm also not COP).
