Wideband Air/Fuel Ratio Gauges
GlowShift Wideband Air/Fuel Ratio Gauges are essential for anyone driving a performance vehicle running on gas or Ethanol 85, giving you the ability to closely monitor and fine-tune air to fuel ratios or to view Lambda readouts. Choose between several different analog and digital wideband air fuel gauges indicating Rich, Optimal and Lean levels. Benefits will include stronger engine performance and better fuel efficiency. This gauge also comes complete with everything required for installation including Wideband O2 Sensors, Sensor and Power Wiring Harnesses and more.

Benefits Of Installing An Air To Fuel Ratio Gauge
Monitoring your car or truck’s air to fuel ratio helps you determine the condition of your vehicle’s oxygen sensor and also reduces emissions, provides higher fuel economy, and maximizes power and engine performance. A Gas Air Fuel Gauge or E85 Wideband Gauge assists in detecting an issue with your oxygen sensor to avoid an increase in fuel consumption or pollutant emissions, while also preventing a decrease in power. A stoichiometric AFR is achieved when you have the correct amount of air and fuel to produce a chemically complete combustion event. For gasoline engines, the stoichiometric ratio of 14.7:1 allows the catalytic converter to operate at maximum efficiency, resulting in reduced emissions. A lower AFR number contains less air than the 14.7:1 ratio and is therefore classified as a richer mixture. For E85 engines, the stoichiometric ratio of 9.7:1 is recommended for producing peak performance results. An air/fuel mixture that is leaner than the stoichiometric ratio will have a higher AFR number, which results in more air being present and can be dangerous in turbocharged vehicles. Installing an AFR gauge can also help boost engine performance by allowing you to carefully map out your car or truck’s air to fuel ratios throughout the range of RPM and manifold pressure, leading to maximized power output.
What’s In Each Wideband AFR Gauge Kit?
GlowShift’s Wideband Air Fuel Ratio Gauges have you covered with a full set of parts for the install. Both digital and analog wideband gauges include an LSU 4.9 Wideband Oxygen Sensor; 12 Volt Wideband Controller with Data Logging Output; Mild Steel Weld-In Sensor Bung with Plug; 13’ Sensor Wire Harness; 6’ Controller-to-Gauge Wire Harness; 5’ Power Wire Harness; 3’ Data Logging Harness; and Mounting Hardware. Each digital dual wideband gauge includes (2) LSU 4.9 Wideband O2 Sensors; (2) Digital 12 Volt Wideband Controller Units with Data Logging Output; (2) 10’ Sensor Wire Harnesses; (2) 3’ Controller Unit to Gauge Wire Harnesses; (1) 7’ Gauge Y-Harness; (1) 5’ Power Y-Harness; (2) Mild Steel Weld-In Bungs; (2) Stainless Steel Weld-In Bungs; (2) Bung Plugs; and Mounting Hardware.
A Wideband AFR Gauge provides a precise numerical reading down to the decimal place of your vehicle’s air/fuel mixture. Each 2-1/16” Wideband Gauge utilizes the included LSU 4.9 wideband oxygen sensor to attain accurate readings directly from your vehicle’s exhaust manifold. This gauge also comes standard with a 0 to 5 volt digital output that allows you to connect it to virtually any data logging or engine management system. For high performance vehicles looking to really tune their engine, we recommend a Wideband AFR Gauge as a more accurate monitoring tool.
GlowShift Digital Wideband Gauges: Gas AFR, E85 AFR, or Lambda Readings
With GlowShift’s Digital Wideband Air Fuel Gauge you can select either Gasoline AFR readings from 10.01 to 20.00 AFR, E85 readings from 6.66 to 13.31 AFR, or LAMBDA readings from 0.683 to 1.365. Each digital wideband gauge features the option of a single or dual display with multiple color settings and ultra-bright LED readouts. With this gauge you’ll be able to carefully map out your vehicle’s Air to Fuel Ratio through the range of engine RPM. Take accurate 4-digit readings that are precise down to one decimal point so you can tune your vehicle for optimal performance.
Single Wideband AFR Gauges Versus Dual Wideband Gauges
With Single Wideband Air Fuel Ratio Gauges and Dual Wideband AFR Gauges, the primary difference is that you’ll have one O2 sensor installed in comparison to two for Dual Wideband. The dual wideband air/fuel ratio gauge monitors the left and right banks of a vehicle’s exhaust system. Doing so allows you to quickly and accurately diagnose which side of the engine is either underperforming or causing an issue so that it can be adjusted to prevent engine damage. A single wideband gauge gives you those same readings and diagnosis, but you cannot pinpoint which bank is underperforming versus the other due to only one oxygen sensor being installed.
