The instances of Closed Loop and SAS cannot overlap. The narrowband O2 sensor is very sensitive to ANY oxygen.

SAS is incompatible with Autotune.

Although an LC-1 or one of the other solutions could be used on its own, I think that a BoosterPlug and LC-1, etc. are better as a pair.

The fact that the SAS point changes at a lower RPM as you go higher in the gears is indicative of it being tied to throttle-angle/manifold-vacuum. I heard this from a designer too.

Hey, I thought you were going to go a step at a time.

If you want a fresh start put +10 in all the 13.2 cells and put +6 in all the 13.8 cells. That will speed autotune a lot.
