Monitor the Left & Right Banks of Your Engine
GlowShift’s 10 Color Digital Dual Wideband Air/Fuel Ratio Gauge allows you to closely monitor and fine tune the left and right banks of your engine from a single gauge! This wideband air/fuel ratio gauge is electronically driven and reads air to fuel ratios from 10.0 to 20.0 AFR. Featuring 2 customizable displays with bold, easy to read, quick glance digital readouts, users have the ability to set each of the displays a different color to quickly identify which reading is which bank of the exhaust. Each wideband gauge kit comes included with everything needed for a complete installation such as (2) wideband oxygen sensors, (2) digital 12 volt wideband controllers with data logging output, (2) sensor harnesses, (2) data logging harnesses, (1) gauge y-splitter harness, (1) power y-splitter harness, (2) mild steel weld-in bungs, (2) stainless steel weld-in bungs, (2) bung plugs, and a step-by-step installation guide to walk to you the installation process.

Benefits for Your Vehicle
Installing wideband air/fuel ratio gauges to high performance cars featuring a V6, V8 or V10 engine offers numerous benefits such as reduced emissions, higher fuel economy and maximized power and engine performance. This allows you to carefully map out your vehicle’s air fuel ratios through the range of RPM and manifold pressure which results in maximized power output. The 0 to 5 volt digital output allows you to connect the gauge to any data logging or engine management system to log real time data for more precise tuning. This gauge can be used on any vehicle that runs unleaded gasoline.

Dual Wideband vs. Single Wideband
Dual wideband air fuel gauges allow you to quickly and accurately identify which side of the engine is underperforming or causing an issue that can be adjusted to prevent engine damage. A wideband gauge with a single display will give you the same accurate readings and diagnosis, but you will not be able to specify which of the 2 banks is performing optimally or underperforming.

10 Color Digital Series Features
Each digital gauge features 10 different LED color options that include blue, green, red, yellow, white, teal, purple, pink, amber and orange by pressing the button on the gauge face. After the color orange, there are 2 additional modes that you can set your gauge to: the color fade and color cycle mode that utilizes each of the 10 featured colors. This 10 Color Digital Gauge features a diameter of 2-1/16” (52mm) with a flat gauge face and an ultra-thin design. The 2 digital displays measure at 0.66” x 0.36”. At startup, the gauge performs a self-calibration sequence that ensures it is functioning properly. For an easier viewing experience when driving at night, connecting the orange wire from the power harness to the headlight switch source dims the brightness of the gauge 50% when the headlights are on for a more subtle glow.

  • Great Product for a great price

    Posted by Stephan Manley on May 15, 2020

    I love my new gauges. The price couldn't be beat and the quality is awesome. The only thing I would have liked to see was more options for the Power harness length and power daisy chain harness length. I did purchase the optional 3' length daisy chain harness and it seemed to be JUST long enough. I do love having the daisy chain as an option over running multiple sets of power/accessory/ground/dimmer wires. That definitely made life easier and the install cleaner. I installed the 10 color Elite series Black 30PSI Boost/Vacuum, 0-100PSI Oil Pressure, 0-100 fuel pressure and the 10 Color Digital Dual Wideband AFR gauges.

    I installed the kit with no issues what so ever. Turned it on calibrated both units and the started tuning on the carburetor. I cant believe I've gone all these years without one. It is an absolute must have for fine tuning data logging. Thanks glowshift for making life simpler
