Features, Description, Q&A, Specs & Installation
Product Overview. The Analog Wideband Air/Fuel Ratio Gauge with a white dial and 7 color backlighting is designed to provide precise and immediate monitoring of engine air-to-fuel ratios, covering a range from 10 to 20 AFR. It is widely used by performance enthusiasts and tuners to optimize engine performance and fuel efficiency by observing real-time air/fuel ratios across varying RPMs and manifold pressures.
Construction and Appearance. This 52mm gauge features a clear flat lens and white dial, complemented by an illuminated red needle that smoothly sweeps through a 270° arc using advanced stepper motor technology for accurate readings. The housing includes seven selectable LED backlighting colors with both solid color and color cycle modes, ensuring vivid, clear visibility in all lighting conditions, including a nighttime dimming function that reduces brightness by 30% when headlights are activated.
Installation. Installation requires welding the included mild steel sensor bung onto the exhaust pipe to mount the LSU 4.9 wideband oxygen sensor. Multiple wiring harnesses must be connected to the controller and gauge for sensor power and data logging functionality. Moderate mechanical skills, including welding, are necessary; drilling is generally not required.
Warranty. The oxygen sensor includes a 30-day manufacturer warranty, while the entire gauge kit is covered by a one-year limited warranty.
Application. This gauge kit is universally compatible with vehicles running unleaded fuel. Some adaptation may be needed depending on the specific exhaust configuration and installation location of individual vehicles.
