GlowShift’s Elite 10 Color Series Wideband Air/Fuel Ratio Gauge is an ultra-high performance gauge that monitors your vehicle’s air/fuel ratio from 10.0 to 20.0, as well as allowing you to tune your vehicle’s air to fuel ratio, resulting in multiple benefits. These benefits include maximized power and engine performance by allowing you to carefully map out your vehicle’s air to fuel ratios throughout the range of RPM and manifold pressure. <br /> <br /> This Elite 10 Color Series Wideband Air/Fuel Ratio Gauge includes a Bosch LSU 4.9 wideband oxygen sensor, unlike many other wideband air/fuel gauges that utilize the older LSU 4.2 sensor. This 4.9 LSU wideband o2 sensor is installed to your vehicle’s exhaust with the included weld in bung, and the 13 foot sensor wire utilizes a modular connector to securely connect to the included wideband control box. The included power wires and wire harnesses are completely plug and play, and securely snap into the wideband control box, as well as the back of the gauge. <br /> <br /> GlowShift’s 2 1/16th inch (52mm) Wideband Air/Fuel Ratio Gauge includes an easy to read analog readout, a peak recall function, programmable high and low warning functions, stepper motor technology, as well as 10 color through dial LED lighting, a self-calibration mode. The adjustable high and low warning functions will alert you visually or with an optional audible tone, ensuring your vehicle’s air/fuel mixture is running at optimum levels. The included stepper motor ensures all needle movement is incredibly smooth and all gauge readings are extremely accurate. GlowShift’s 10 color through dial lighting lets you match your stock gauges or add a unique look to your vehicle’s interior. <br /> <br /> GlowShift gives you a 0 to 5 volt digital output with this Wideband Air/Fuel Gauge’s controller, allowing you to connect it to virtually any data logging or engine management system.
