After 2 weekends of trying i'm back to square one lol. Ended up back to cheating the system once again during the 20-1mph GM rolling idle thing by increasing the throttle blade angle at idle to blend that seam and keep a solid idle. Unfortunately, 950 is as low as i can go and still keep a few iac counts with no a/c commanded at 0 mph. Got my fingers crossed that there will not be any cold idle flare like before.
Spent a number of hours trying silly things to override that part of the OS to no avail. Spent another number of hours trying to get this engine to idle consistently @ 675rpm to give the pcm what i assume it wants to no avail. Learned a lot. Got confused even more...
There is a tiny tuner/user defined parameter rabbit hole that might help with this. There are manual trans segment swaps that can be done supposedly. I could be overlooking something too.... Maybe reconnecting the evap system might be beneficial....Maybe i should just be happy the way it is, lol.
