• 【EASY INSTALLATION】: Wideband AFR gauge is made of high quality materials and technology and is easy to install thanks to its standard 52mm housing. You can easily install it in almost any location. at the same time, it never requires free-air calibration when used with our wideband O2 UEGO AFR gauge.
• 【Flexibility and Expandability】: The controller box in the kit is highly flexible and expandable. You can adjust and expand the controller box configuration to meet the requirements of different vehicles and applications. The ability to customize the controller box's connections and parameters according to the engine management system's specifications and personal preferences to achieve the best fit and performance optimization.
• 【WIDE COMPATIBILITY】: Our air fuel ratio gauge comes in a standard 52mm (2-1/16 inch) housing that fits in a variety of instrument pods, providing flexible mounting options. Our digital wideband gauge features a 0-5V analog output and is compatible with a wide range of engine management systems and data loggers, providing even broader compatibility.Compatible with vehicle/system voltages up to 16V.
• 【Accurate and Fast Feedback】: The UGEO Air Fuel Ratio Gauge is equipped with a 4.9 LSU sensor that provides real-time feedback with high accuracy and fast response time. It responds instantly to every 0.1 change in air/fuel ratio, giving you more time and accurate information when making adjustments.
• 【Versatile design】: In addition to measuring and displaying the air/fuel ratio, the Air/Fuel Ratio Gauge also features a broadband measurement and digital display. This means you have access to more comprehensive data and insight into your engine's combustion state for precise tuning and optimization.
