A used 0411 GM PCM is ordered and coming, with connectors. Dongle to connect ODB2 port to laptop is ordered and on the way. I ordered a female ODB2 port connector in order to make up a bench harness, a bench DC power supply, some mini-boxes and toggle switches, all of which have arrived already.
I've got PC Hammer (the PCM reader/programmer) running in WINE on Linux, and also TunerPro (PCM editor) and Universal Patcher (PCM Editor) also seemingly running in useful fashion on WINE. If they do have problems there, I can alternatively run them in a Win7 Qemu virtual machine.
I also ordered a scrap "black box" PCM, like the one in my Silverado now. My idea is to cut its ports off, and make up an adapter harness using the 0411 connectors that just plugs the new 0411 PCM into the existing truck's harness.
Usually in a swap people re-pin the 0411 connectors using the existing truck harness -- very involved. That's more of a permanent swap. I'd like to test the swap first before committing, and making an adapter cable would let me switch back to the old PCM easily, if I wanted. I haven't heard of anybody doing that, but I thought it was worth a try since the scrap blackbox pcm was cheap enough to give it a shot.
So I'm pretty close to wreaking havoc.......
