I was also thinking about how the ECU uses that sensor. It doesn't directly determine anything. So if that sensor has a little bit of variation (not necessarily all of what I am finding) then it won't bother the ECU because it is only looking for major changes. I.e enrichening at WOT.

I need to grease the 2 rear regulators up then hopefully some testing will be done. I still don't have a great road found, but I have 2 that show some promise. The speed limit on one of them is pretty low though. Only 45 mph the other is 55 posted, so "60-65" mph to the general public
