AEM‘s X-Series Wideband UEGO Air/Fuel Ratio Sensor Controllers are built upon unique, patent-pending X-Digital technology that makes them the fastest responding wideband air/fuel ratio controllers.

X-Digital wideband technology gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating condition. The controller’s high speed digital implementation ensures no loss of signal fidelity and full transient response, making it able to identify the slightest fluctuations in AFR and output them in full value.

Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM’s Wideband Controllers with X-Digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning.

The X-Series Wideband UEGO AFR Sensor Controller Gauge (PN 30-0300) measures 2 1/16 inches (52mm) in diameter, and features a modern, visually striking faceplate and new seven-segment center display that is 87% larger than previous AEM gauges. The user can 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 fuel and Lambda are included, and an optional silver faceplate with white dual-faced fuel/Lambda faceplate is available. 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.
