GlowShift’s Wideband Air/Fuel Ratio Gauges are an essential accessory when tuning your performance vehicle. We offer a variety of 52mm Wideband Air / Fuel Ratio Gauges in both digital and analog gauge models that allow you to closely monitor and tune your vehicle’s air to fuel ratio with the included data logging capability (data logging not available for Tinted Gauge Series). Doing this gives multiple benefits to your vehicle including reduced emissions, higher fuel economy, as well as maximized power output of engine performance by allowing you to carefully map out your vehicle’s air to fuel ratios throughout the range of RPM and manifold pressure.

Digital Wideband Air/Fuel Gauges:

Our Digital Wideband Air Fuel Gauges are available in our Black 7 Color, Tinted 7 Color, and White 7 Color Gauge Series, as well as Blue Digital, Red Digital and Tinted Gauge Series. Each digital Wideband Air to Fuel Ratio Gauge features an easy to read blue digital readout (except for Red Digital Series) that displays your vehicle’s air/fuel ratio from 20.0 to 10.0 AFR down to the decimal place. The featured three color LED ring surrounding the digital display indicates Lean (Red), Optimal (Yellow), and Rich (Green) values so you can optimally tune your vehicle for your needs. The three color LED ring is only featured with the Black 7 Color, Tinted 7 Color, White 7 Color, and Tinted Gauge Series, but NOT with the Blue Digital and Red Digital Gauge Series.

Analog Wideband Air/Fuel Gauges:

GlowShift’s Analog Wideband Air/Fuel Gauges are available in both Elite and White Elite Gauge Series that read from 10 to 20 AFR and include a peak recall function, programmable high and low warnings, and stepper motor technology which allows for extremely smooth and accurate movement of the illuminated red needle. The programmable high and low warnings will send alerts visually and/or audibly with a tone that notifies you that your vehicle’s air/fuel mixture is at optimal levels. Users can select from 10 different LED colors to illuminate their gauge to match their vehicle’s interior or to add a custom, aftermarket style.

Data Logging Capability:

This data logging function allows you to send output signals to an aftermarket data logger. There is a 0-1V output, 0-5V output, and ground output for the connection to the data logger. Again, the data logging output capability is NOT available for the Tinted Series Wideband Air/Fuel Ratio Gauge.

Included Components:

What sets GlowShift’s Wideband Air Fuel Gauges apart from the competition are the vital components that come included with each gauge such as the Bosch LSU 4.9 Wideband Oxygen Sensor and Digital Wideband Controller Unit with Data Logging Output. The Bosch O2 Sensor installs directly to your vehicle’s exhaust with the included Weld-In Bung and relays statistics to the Wideband Controller for precise readings from the source. Other gauge components that are included with your GlowShift Wideband Air/Fuel Gauge to ensure you have everything you’ll need for a seamless installation are the 13 ft. Sensor Wire Harness, 6 ft. Controller to Gauge Wire Harness and 5 ft. Power Wire Harness. GlowShift Gauges includes a one year limited warranty and free lifetime technical support with every Wideband Air/Fuel Gauge purchased.
