CMP retard pid

[[email protected]]

Im sorry if this has been already discussed but in searching I found nothing newer than 2018 on the subject. I have a GM based PCM that I would like to look at the CMP retard value on but cant find the PID in the scanner. Am I overlooking it or is it just not there? I read several posts on where to find it and add it but I am unable to find it anywhere. If it is not there, could it be added? Ive got a brand new Blueprint 383 MPI sitting in my truck that wont run right and I have a hunch that the cam retard is not right. Any help would be greatly appreciated!

CMP has nothing to do with spark timing, it is only for determining #1 TDC compression from #1 TDC exhaust, since both those look identical from the CKP's perspective. Spark timing is solely taken from the crank position sensor.
