Feature
●【Feature】Upgraded New Air/Fuel Ratio UEGO Gauge wideband O2 AFR Gauge features a digital LED display and LED "needle" that change color as the AFR goes from rich to thin. At the same time, the AFR Gauge can be switched between 3 display modes: air-fuel ratio, lambda, and oxygen percentage, which means that you can monitor your vehicle condition accurately, efficiently and quickly.
●【Widely Compatibility】 The Gauge comes with an carbon fiber shell, which is beautiful and protective. Wideband Air Fuel Gauge has a 52 mm (2-1/16 inch) Gauge Housing, this Digital Wideband Gauge can be easily installed in most instrument pods. Our X Series Wideband UEGO Air Fuel Ratio Gauge have 0-5V & RS232 output, which can be used with data loggers and almost all engine management systems, compatible with vehicle/system voltages up to 16V.
●【High-Quality Products】Accurate A/F Ratio Data is crucial when adjusting the engine. Featuring X-Digital wideband technology, which enables these controllers to read and report values more faster that other controllers cannot, providing more optimized engine tuning and a safer overall operating condition - Display AFR values in hundredsths of %. At the same time, it never requires free-air calibration when used with our wideband O2 UEGO AFR Gauge.
●【TWO Calibration Modes】Resistor Trim Mode(rCAL) or Free Air Mode(ACAL)? It is up to you! The supplied UEGO Sensor is factory calibrated via a trim resistor, integral to the sensor connector, and rCAL is the recommended calibration mode for best accuracy, for most users, there is no further action or calibration required. The gauge features a modern, visually striking faceplate and new seven-segment, center display that is 87% larger than previous generation.
●【Tips】The Air Fuel Ratio Gauge is not water-proof and should not be installed in a location with exposure to water or snow. Wideband meters have a 52mm housing and are supplied with brackets and thumbscrews for easy, plug-and-play mounting to panels or gauge pods. It is recommended that the Gauges need to be securely mounted with the Brackets provided to ensure they do not come loose. Installation instructions are included to assist you with the installation and wiring procedures.

Important Notes on Wiring：
• Route harnesses carefully to avoid chafing or undue strain.
• Secure wiring to vehicle with wire ties. Paying special attention to the sensor harness routing beneath the vehicle and/or in the engine compartment.
• Take care when routing sensor harness near hot exhaust components.
• Apply strain reliefs and wire coverings as necessary.
• Use a 5A inline fuse on the switched 12V power supply line (Pin 1-Power/IO).
• Avoid cutting or extending the sensor harness.
• Use appropriate gauge wire (20 AWG or thicker) when extending wires, especially Pins 1(Switched 12V)or
2(Ground) of the Power/10 harness.
• Ensure all connections are secure and insulated from shorts to adjacent wires and the vehicle structure.
• Utilize proper crimping and solder/heat shrink techniques.
