Product details
The AEM Wideband X-Series 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.
