Just as the title says - can anyone explain the sequence of events and feedback that occurs once we enter PE mode?
I have been testing by adjusting up and down commanded AFR in PE. I have allowed plenty of time to learn. Whatever I set commanded to does nothing to change actual AFR. So what's the deal? Is it only MAF that is commanding AFR?
Also, does the narrowband signal come into play at all in PE? I would guess that it is being ignored, but I want to make sure.
Thanks for any info.
