I'm trying to diagnose a sketchy idle on my Eaton blown 2v. It was stalling out with the weather being really hot and humid but never had an issue before but weather was different. I did a long hot idle datalog and noticed that the spark source was mainly 8 (idle feedback minimum clip) but at times a few blips going to 9 (idle feedback). Spark advance was 8 degrees when at spark source 8 (despite "lowest spark value for idle control" being set at 10) and jumped up to as high as 11.5 when it went to spark source 9.
Should a healthy idle sit at spark source 9 the whole time??
