Description

The AEM X-Series Wideband UEGO AFR Gauge Kit (PN 30-0300) is designed for tuners and performance enthusiasts seeking precise real-time air-fuel ratio (AFR) readings. This gauge features a modern, visually striking faceplate with a large, 7-segment center display that is 87% larger, offering enhanced readability. With a mounting surface diameter of 2 1/16th-inch (52mm), this gauge is designed to fit into most standard gauge pods and can be mounted virtually anywhere. It boasts an ultra-slim design with a depth of only .200 inches, and comes with black bezels. The gauge offers configurable display options via buttons on its face for changing AFR values and includes a sweeping 24-color-coded LED display for quick visual assessment. For advanced users, the gauge provides essential output options including a 0-5v analog output for data logging or feedback control systems, an RS232 Serial Port, and AEMnet (CANbus) output for seamless integration with data logging systems.
