Considering this thread is about lean cruise, not make my car run on exotic fuels at 1 lambda using AFR numbers in the PCM.... you could trick your narrowband to look for a switch point of like 150mv to achieve some form of close loop lean cruise, although it would be a complete mess and probably wouldnt work.
Unless I mis-typed something, I don't see where we disagree.



Whatever that table is set at, plus all active adders/mutipliers is what 1.00 Lambda is equal to.

What Kyne is saying, is that the trims will try to correct it back to 14.7:1, no matter what is commanded, which isn't true.
