I searched for a post on the differences in the different wideband O2 sensors on the market but could not find a writeup on the pros and cons of the different sensors and whether or not you need a led display with a MS ecu. I feel it may be hidden in a different subject.

Maybe a o2 sensor section in the wiki since it is an ever changing subject?

Could someone please help me out without flaming me too bad? A link would be fine if it has already been discussed.

Thanks to all!
