Ok, I am bound and determined to do this with 98-00 vortec. In other threads guys have said they did it. But I can't figure how. I've put a lot of time into it with failure. Ended up doing it the old way and spreadsheets... Have done it on other engines by working with available tutorials.
With all the excellent help here I'm sure I can come up with a Tutorial. Biggest issue right now with available tutorials is missing PIDS. Have the calc_pids.txt installed from one of the tutorials. I do have a Wide Band but would also like to do one without. So 2 tutorials, actually they could mirro what is there but work for the Vortec.
From another thread.
So do I have an issue? Or where to start if these PIDS are not available in the Vortec PCM?
