Description

The UEGO gauge will indicate changes in the air/fuel ratio in real time, which is essential when you aim to perform safer, more powerful and accurate engine tuning. Specifications: 52mm(2-1/16") Diameter Mounting Compatible with Vehicle/System Voltages up to 16V 0-5V Analog Output Serial RS-232 Output 20ms Typical Response 8.0:1 to 20.0:1 AFR / 0.55 to 2.00 Lambda Configurable 3 or 4 Digit Precision Display Modes Configurable AFR, Lambda or O2% Display Modes Free Air or Resistor Trim Calibration Modes Auto Dimming Feature Gledewen Wideband UEGO Air Fuel Ratio Gauge Kit Includes: 1 * UEGO Gauge 1 * Wideband Oxygen Sensor 1 * PWR/IO Cable 1 * Sensor Harness 4 * Butt Connectors 1 * Silver Nut 1 * Installation Instruction Usage Steps 1. Connect Harness A to Port A. 2. Connect Harness B to Port B. 3. Connect the other end of Harness B to the sensor. 4. The other end of Harness A has a red wire for the positive terminal and a black wire for the negative terminal. 5. Connect to a 12V power supply. The instrument will start working, with a working voltage of 12V. 6. The dashboard has a setting and selection button, allowing for 8 function switches. 7. In the 4-digit mode, press the left button to switch to the 3-digit mode. Press the select button to confirm, which will change to 3-digit mode. Keep pressing to switch to the initialization mode or air-fuel ratio mode. 8. Change to CAN mode for engine combustion ratio calibration and adjustment. This can increase the combustion ratio and improve engine efficiency.

Features

【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.
【Widely Applications】A wide range of applications is waiting to be explored. The wideband o2 sensor gauge provides 0-5V analog and serial RS-232 output that make it perfectly compatible to get access to read and record data from controllers, meanwhile, it supports vehicle/system voltages up to 16V.
【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
