Jeff, thats 100% Valid in the OS 12212156 I tested. Edit: Per Joecar's reasoning when in closed-loop, PE is enabled..you really stay in closed-loop (+LTFT's applied). Some OS's will say OL-Drive, but its probably never really enters 'classic' Open-Loop..
What about before the car goes into closed loop (when ECTs are lower than the CL threshold)? I know the logs I have would show the commanded AFRs that follow the CFOL table. But, I never really get on the car to find out if PE took over.
Like you, I have never stomped on it while the vehicle is warming up. I guess one could enable TPS for say 1-2% and try it..but like you I found it always follows CFOL when warming up..per Joecar's reasoning, since it is not closed-loop yet..I bet it will always follow CFOL in 'cold'-open-loop..(see attachment)..
I do agree with the other half of what you're saying. When CL is turned off, fueling will follow the CFOL table until PE is enabled, at which point it'll take the richer of the two.
