Re: Wideband A/F and A/F gauges
A typical production vehicle uses oxygen sensors that have a very narrow resolution. When you are cruising / idling (closed loop), the vehicle is concerned with maintaining an A/F ratio of 14.7 (stoich). When you put your foot on the floor and go into power enrichment (open loop), the factory sensors do not have enough resolution to tell you an exact A/F ratio. Any system that ties in to the factory oxygen sensors can only tell you if you are richer or leaner than 14.7. The wideband sensor, will tell you exactly what A/F ratio you are running. The Wideband comes with a plug you have to weld into the exhaust to be able to screw in the sensor supplied with the guage.
