MaxTow’s Double Vision™ White & Blue Wideband Air/Fuel Ratio Gauge is essential when you’re tuning any truck with a gas engine. Closely monitor your truck’s air to fuel ratio with analog and digital readouts from 10.0 to 20.0 AFR, accurate to one decimal place. Carefully map out your truck’s air to fuel ratios throughout the range of RPM and manifold pressure. This wideband air fuel ratio gauge delivers benefits like reduced emissions, higher fuel economy and maximized power output and engine performance. Get ready to hit the road and Tow to the Max™
MaxTow’s White & Blue Double Vision™ Gauge Series features a white gauge dial and blue LED display with an illuminated red needle. You get the classic look of an analog gauge combined with a blue digital numerical readout. This 2-1/16” (52mm) gauge outperforms the competition with features like stepper motor technology which allows for all needle movement to be exceptionally smooth and all gauge readings to be extremely accurate. Brightness Recall remembers the previous brightness setting before powering down your truck.
MaxTow’s wideband air fuel ratio gauge kit includes a 10’ sensor harness and 5’ power harness, both with extended lengths for added flexibility during the wideband air fuel gauge install. There is also a 7’ Gauge Harness, and 3’ Data Logging Output Wire so you can connect to virtually any data logging or engine management system for further fine tuning. Easily attach harnesses to the back of the gauge by utilizing seamless Plug and Play connectivity. As you search for the best wideband gauge for your truck, MaxTow’s goal with our wiring kits is to make installation seamless and straightforward. Note: The Wideband Oxygen Sensor includes a 30 day manufacturer’s warranty. MaxTow does not warranty this oxygen sensor after that 30 day time frame.

MaxTow wideband AFR gauges feature innovative Daytime and Nighttime Dimming Modes with three customizable brightness settings (Low, Medium, High) for each mode. This gives you multiple dimming options, allowing you to set your individual preference when hitting the road during the day or later on at night. Adjust for the right amount of brightness as you’re taking readings.
A MaxTow wideband air fuel gauge helps detect any issues with your oxygen sensor to avoid an increase in fuel consumption or pollutant emissions. A stoichiometric AFR is achieved when you have the correct amount of air and fuel. For gas engines, the stoichiometric ratio of 14.7:1 is optimal. A lower AFR number contains less air than the 14.7:1 ratio and is therefore classified as a richer mixture. 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 trucks. Installing the best wideband air fuel ratio gauge will ensure that you’re getting accurate readouts and feedback for your truck.
