Product Details
✓【What A Easy Helper!】 Featuring sweeping 24-color-coded LED display and four-digit central readout, the faceplate of wideband gauge is two-sided and reversible. Thanks to it, the afr gauge can switch between 3 display modes of air-fuel-ratio, lambda, oxygen percentage at will, by that means you are able to effectively but quickly monitor your vehicle's conditions.
✓【Core Technology】 To maximize your engine's power while stay safe, an air fuel ratio gauge kit is must-have! The Gledewen AFR gauge helps to identify sensitively every slight fluctuations of air-fuel ratio and report precise and reliable reference to the car engine in real-time, and in particular it matches with LSU4.9 UEGO, ensuring its faster and more precise response(20ms typical).
✓【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.
✓【Installation Instructions】Mount the 52mm gauge, connect power and ground wires, and install the LSU 4.9 sensor into the exhaust bung for quick setup.
✓【12-MONTH WARRANTY】If the wideband AFR sensor controller gauge kit fails, stops working or any other problems, you can rely on our service of carefree REPLACEMENT or REFUND
