Done 2 runs w the new extension harness, and motor seems to be running real well. Whatever I did worked, including eliminating the O2 sensor signal drop I had on the Right Bank. No loss of signal now. However, I am getting a C/L to O/L to C/L flip flop at times. The hotter the CTS the less it happens but looking at the logs, my best guess is that I am hitting the top or bottom of the C/L O2 window.
That's what seems to be going on. Should I leave them alone or increase the spread? Right now its stock at .698v/.198v. Its seems to be more frequent w cooler MAT/IAT temps.
Maybe run less Prop Gain?
