AEM Electronics X Series Air Fuel Ratio Gauge (MPN: 30-0300)

Advanced digital gauge for precise air/fuel ratio monitoring and tuning.

The AEM Electronics X Series Air Fuel Ratio Gauge is designed for accurate and rapid monitoring of air/fuel ratios in gasoline engines. Utilizing patent-pending X-Digital technology, this gauge offers the fastest response times in the market, ensuring optimal engine tuning and safety. The high-speed digital implementation guarantees signal fidelity and full transient response, which enhances feedback control for a more powerful and precise engine performance.

Featuring a modern round design with a 2-1/16 inch diameter, the gauge is equipped with a visually striking faceplate and a seven-segment display that is significantly larger than traditional models. This allows for easy reading of critical data at a glance. The gauge supports the Bosch 4.9LSU sensor and offers versatile calibration methods, including factory calibration and free-air calibration.

With a range of 8:1 to 18:1, the AEM X Series gauge includes a 0-5V analog output for data logging and feedback control, as well as an RS232 serial port output. Additionally, it features AEMnet (CANbus) output, enabling daisy chaining of up to 16 X-Series widebands for comprehensive monitoring of air/fuel ratios across multiple cylinders.
