AEM X-Series Wideband UEGO AFR Gauge with OBDII - 52mm

Real-time air/fuel ratio, read straight off your OBDII port. AEM's X-Series wideband uses patented X-Digital technology - in independent testing against 17 competing controllers, it was the fastest responder in the group, and faster feedback means a safer, more accurate tune.

Ships with a Bosch 4.9LSU sensor that's factory-calibrated out of the box, with free-air calibration available as the sensor ages. The 52mm housing is only 0.825" deep with a 0.200" cup, so it fits pods and dash cutouts that won't take a conventional gauge.

Compatible with EFILive, HPTuners and DashDaq. Includes 0-5V and RS232 outputs for data logging plus AEMnet CAN for daisy-chaining up to 16 cylinders. Black bezel and reversible dual-faced black faceplate included; silver bezel/white faceplate available separately (30-0300-ACC). Auto-dimming, locking connectors, and a configurable display for AFR, Lambda, or O2%.
