I knew Open Loop didn't mean just WOT, but I guess I WAS confusing the two when I talked about WOT fuel, wasn't I? Sorry bout that!
Isn't there a limit of some sort on the possible adjustment available in the Closed Loop fuel trims? In other words, if things are badly out of adjustment, it may not be possible to achieve the desired A/F ratio? I seem to remember reading this somewhere.
