And most non-performance set ups don't use it either - at wide open throttle. They drop back to open loop.

no computer, whether factory or aftermarket, or person generally would want closed loop at WOT.

Even if I had a wideband system and no transient delay with a failsafe boundary condition I would still avoid using it for multiple reasons, but mainly because it is useless... for most applications.

Discussion helpful on all fronts....actually, just read an article --- processing speeds and sophistication of algorithms is getting to/at the point where controlling via feedback under all conditions is possible and/or right around the corner. All that being driven by (like it or not) increasing pressure on reducing emissions and fuel consumption.

Well, who knows, but capability exists now. Certainly OEM's -- but I doubt the aftermarket stuff will get there soon, but you never know. Hell, Mazda just released compression ignition gasoline engine - 16:1 CR - runs much of the time without/with minimal spark. Go figure.
