AFR (Carburation) control gauge from the renowned AEM company. Wideband probe for the most accurate reading possible.

 AEM UEGO Broadband Digital AFR Gauge
 The popular UEGO AEM Wideband O2 meter features a digital LED display and a wide LED “needle” that changes color as the AFR changes from rich to lean.
 A 52mm (2-1/16") gauge housing ensures it will fit most gauge mounts and can be remote mounted virtually anywhere.
 All AEM digital gauges feature a 0-5V analog output for use with data loggers and most engine management features.
 Each gauge features 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).
 The Bosch UEGO probe gives the controller speed and precision.
 The 4.9 LSU sensor has the same fuel compatibility as the 4.2 LSU and NEVER requires free air calibration when used with AEM's 30-4110 UEGO wideband AFR gauge. The 30-4110 4.9 LSU sensor uses a different connector than the connector used with the 4.2 LSU sensors included with the original and discontinued 30-4100 gauge controller.
 The sensors are not interchangeable in any way between the two controllers, including changing the connectors on the meters.
