Pishta,
Your question was interesting, so I tried to find some information about ideal idle AFR. Turns out the first site that came up in Google was very informative. Thought this might be a useful reference for most.

AFR+ Basic Functionality - Understand AFR Values, Wideband O2 Sensors, and Fuel Trim vs. Auto Tune Modes of our Fuel Controller.

I read the idle part but still don't buy it. Idle is no load, no reason to run anything fatter than stoich, buy i suppose they know more than I do about this but have read many thay idle and light cruise should be on the lean side but that may be coming from a mileage attitude. Thanks
