AEM X-Series Wideband Gauge 52mm 2 1/16" O2 UEGO Air Fuel AFR Controller 30-0300 Description>>>>BRAND NEW IN BOX X-SERIES WIDEBAND UEGO CONTROLLER FEATURES: X-Series Wideband UEGO AFR Controller Gauge were fastest responding wideband air/fuel ratio controllers in an independent test vs. 17 competitor AFR controllers Includes Bosch 4.9LSU wideband UEGO sensor Factory calibrated resistor does not require free-air calibration, but technology allows for free-air calibration as sensor ages if user desires Compatible with vehicle/system voltages up to 16V 0-5V & RS232 output for data logging and feedback control, AEMnet (CANbus) for data logging and daisy-chaining multiple controllers up to 16 cylinders Can display AFR values in hundredths of % 52mm gauge diameter and slim 0.825” gauge depth Gauge cup depth only .200” deep! Auto dimming feature User configurable display via buttons on the gauge face for changing AFR values, Lambda and O2%, and 3- or 4-digit display Locking connectors Black bezel and black dual faced faceplate included (gauge only, silver bezel/white gauge option sold separately)Buy together with the white faceplate, save $15 https://www.ebay.com/itm/254265875140 MANUFACTURER PRODUCT SPECIFICATIONS AEM’s X-Series Wideband UEGO Air/Fuel Ratio Sensor Controller Gauges are built upon unique, patent-pending X-Digital technology that makes them the fastest responding wideband air/fuel ratio controllers in independent testing against 17 other wideband UEGO air/fuel controllers*. 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 Gauge’s 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 allow 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 gauge’s 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.
