This is one reason I have been saying to ignore the O2. Tune it to best performance without O2 numbers, as you are trying to find the right numbers. You can tune idle (and other ranges) with no O2 at all, and is actually the preferred method, instead using other indicators such as MAP. Glad to see it's idling well now!
