I guess I should have done some research first. Thanks anyways bro! So a narrow band guage only reads properly when its in the stoich range 14.7?

At part throttle, a narrow band gauge just flips back and forth if it is fast enough, or it just sits at stoich if it isn't. It shows rich at WOT and lean on decel.

Basically, it is a light show.

Oh I see. I guess I will invest in somthing else, although flashing lights tends to be a good conversation starter.
