Wideband Air/Fuel Ratio Gauges

Benefits of a MaxTow Double Vision® Wideband Gauge for Trucks

Monitoring your truck’s air to fuel ratio helps you determine the condition of your truck’s oxygen sensor and also reduces emissions, provides higher fuel economy, and maximizes power and engine performance. A wideband air fuel gauge assists in detecting any issue with your o2 sensor to avoid an increase in fuel consumption or pollutant emissions, while also preventing a decrease in power. Installing a wideband gauge ultimately helps boost engine performance by allowing you to carefully map out your truck’s air to fuel ratios throughout the range of RPM and manifold pressure. In your search for the best wideband air fuel ratio gauge, make sure to add MaxTow’s Wideband Gauge that is built for any truck make and model.

MaxTow Double Vision® Wideband AFR Gauges Made for Trucks

At MaxTow our goal was to create a lineup of gauges specifically designed for trucks. All of our products are made by truck owners, for truck owners. MaxTow Wideband Air/Fuel Ratio Gauges are dedicated to getting the most out of your truck for those long road trips or heavy hauls. These gauges not only get the job done when it comes to providing accurate AFR readings, but they also look great when installed in your cab. The Double Vision® Series features a dual analog and digital LED display with different color combinations. You can select either a black or white gauge dial, with a green or blue display. The illuminated red analog needle sweeps 270° and is driven by stepper motor technology to create extremely smooth needle movement. Programmable Daytime and Nighttime Dimming Modes will adjust the level of brightness in your gauge’s LEDs depending on the time of day or night. When you’re looking for the best wideband gauge, install MaxTow’s Wideband AFR Gauge to your A-pillar, dash, or another area in your truck and experience enhanced monitoring.

How Do I Install a MaxTow Wideband Air Fuel Ratio Gauge for Trucks?

Installation begins with adding the wideband O2 sensor to your exhaust system. We include a weld-in bung that allows you to quickly add the sensor once this adapter is in place. Run the oxygen sensor wire harness to the gauge, and easily attach it to the included gauge controller using the Plug and Play modular connectors. The power harness connects to the battery or fuse panel and also easily clips into the gauge controller. Then run the gauge wiring harness from the controller to the gauge. Find a location for the wideband gauge on the A-pillar, dashboard or another area inside of your truck, and once mounted you’ll be able to view readings. MaxTow makes the process easy with detailed step-by-step instructions that will walk you through this entire process.
