Am I supposed to be seeing something in cells besides just 16, 17 and 18 in closed loop performance? Don't see anything in the VE MAF analysis. I think I have to start over with the whole trim and analyzer thing. This "learning by doing" exercise is interesting but exasperating.

This would be very, very strange—unless your car never ever goes into any cells that aren’t 16, 17 and 18.

Or if there wasn’t enough data for the other cells, but that would be pretty rare to have enough data for those three but not any of the others.

to get into the normal 'driving range' BLM cells, the car has to be moving, and the CCP (evap duty cycle) must be functional. see http://fbodytech.com/tutorials/charcoal-canister-purge-evap/

Thank you. That explains it. The engine is on a run stand with no transmission attached to it and no CCP or much else on it. I'm going to have to get the engine in some sort of car one day. I'll put a 4L60E behind it. I'll stop asking questions until then.
