Does anybody have the auto meter narrow band? I have it and was wondering where on the led the 12/1 A/F light is. It goes from red to green and at WOT mine settles at the first green light. Thanks guys.

I'm pretty sure its hard to pin point where exactly 12:1 is on a narrow band. In fact, I don't even think they can read that low. They're usually good in the 14-15:1 range. The factory O2 is there to keep the engine stoich. for best fuel economy and such. The computer goes into open loop anyway at WOT, so it makes them useless in that respect too.
