It has combined its single-channel wideband UEGO controller and gauge display into one unit, uniting unsurpassed AFR accuracy and control with an easy-to-read interface. The Gauge-Type Wideband UEGO Controller features a digital LED display and sweeping LED ''needle'' that changes colors as AFR changes from rich to lean. The unit's 52mm (2-1/16'') gauge housing fits in most gauge pods and can be remotely mounted virtually anywhere. Customers say AEM 30-0300 X-Series Wideband UEGO AFR Sensor Controller Gauge The X-Series Wideband UEGO AFR Sensor Controller Gauge (PN 30-0300) measures 2 1/16th-inch (52mm) in diameter and features a modern, visually striking faceplate and new seven-segment center display that is 87% larger than the 30-4110 AEM Wideband Gauges center display. This creates the perception of a larger overall gauge, but in a common 52mm size for easy mounting. Its slim depth (less than one inch overall) and ultra-slim cup depth of .200-inches dramatically increases its application base and potential mounting locations. The X-Series Wideband UEGO AFR Gauge has a user configurable display via buttons on the gauge face that allows you to change AFR values for different fuels, Lambda or O2%, change the center display to three or four digits, perform a free-air calibration if desired as the sensor ages, and change the CAN message ID when linking multiple X-Series Inline Controllers or X-Series Controller Gauges. A black bezel and black dual-faced faceplate for air/fuel and Lambda are included, and an optional silver bezel with white dual-faced air/fuel and Lambda faceplate is available (PN 30-0300-ACC, sold separately). An Auto Dimming feature is included. Locking connectors ensure a positive connection between the harnesses and gauge and a new single board design adds to the new gauges durability. The gauge includes a 0-5v and RS232 Serial Port output for feedback control and data logging, and an AEMnet (CANbus) output for data logging. AEMnet allows additional X-Series Wideband Controllers to be daisy chained together (up to 16 cylinders) for recording AFR in multiple cylinders. It supports vehicle/system voltages up to 16V, and can be used on EFI or carbureted applications, and dynamometers in applications using gasoline, methanol, ethanol, Diesel, propane, and CNG. _x000D_
