AEM Digital Wideband UEGO AFR Gauge (Without Sensor)The World-famous AEM Wideband O2 air/fuel ratio UEGO gauge features a digital LED display and sweeping LED 'needle' that changes colors as AFR changes from rich to lean. A 52mm (2-1/16) gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. All AEM digital gauges feature a 0-5v analog output for use with data loggers and almost any engine management system. Each gauge comes with black and silver bezels and black and white faceplates for multiple color combinations and a custom look (a black Lambda faceplate and black and white Air/Fuel Ratio faceplates).AEM co-developed the new sensor with global automotive supplier FAE culminating in a new sensor design that has a faster response time than the Bosch 4.9 LSU and is less prone to failure in high performance vehiclesPlease note that the gauge is supplied here without a wideband sensor so you can save money with this product if you already have the required FAE 30-2404 sensor.Kit Contents52mm AEM gaugeWeld-in bung52mm (2-1/16”) gauge housingWiring harness and cablingInstallation instructionsFuels compatibility :Gauge Display/0-5V OutputGasolineE85EthanolMethanolLambda values from 0.68 to 1.36Whatever the fuel you will be running the AFR values will always be displayed in gasoline mode (Lambda 1 = 14.7). Got a question?
