    best pcm to use to control 03 LQ4 going to 3bar OS

    As stated Im building a s10 swapped LQ4 and will be going to 3 bar OS and wondering if any pcm will actually be better than another and what they offer thats better than say the original 03 yukon pcm which is what I use a lot of with swaps

    doing a custom harness so I can wire any of them

    I'd use an 0411 PCM, there's more resolution in the VE table when you go to the 3-bar OS if you start with a 12200411 and the 12212156 OS.

    You need to swap the green portions of the PCM plug to red, and there's a minor pin out change, but it's no big deal.
