The AEM X-Series Wideband UEGO AFR Sensor Controller Gauge Accessory Kit provides advanced air/fuel ratio monitoring with customizable features for precise tuning. This 52mm gauge features a slim profile with a depth of only 0.825 inches, making it suitable for tight installation spaces. It includes a Bosch 4.9LSU wideband UEGO sensor and offers fast response times, verified through independent testing against 17 competitors. The gauge’s user-configurable display allows you to switch AFR values for different fuels, toggle between Lambda or O2%, and select a 3- or 4-digit center display for optimal readability.
Connectivity options include 0-5V and RS232 outputs for data logging and feedback control, as well as AEMnet (CANbus) for daisy-chaining multiple controllers up to 16 cylinders. The factory calibration resistor eliminates the need for free-air calibration over sensor lifespan, although calibration can be performed if needed. An auto-dimming feature enhances visibility in various lighting conditions, and locking connectors ensure a secure connection between the harness and gauge.

The accessory kit comes with a sleek silver bezel and dual-faced faceplate for air/fuel and Lambda readings.
