AEM Electronics Wideband O2 Air Fuel Ratio Gauge (MPN: 30-4110NS)

Precision digital gauge for accurate air fuel ratio monitoring.

The AEM Electronics Wideband O2 Air Fuel Ratio Gauge is designed to provide precise monitoring of air fuel ratios in gasoline engines. Featuring a digital LED display, this gauge utilizes a sweeping LED 'needle' that visually indicates changes in air fuel ratio from rich to lean, enhancing the driver's ability to optimize engine performance. With a compact 2-1/16 inch round housing, it is suitable for installation in most gauge pods and can be mounted in various locations for convenience.

This gauge operates within a range of 10:1 to 18.5:1, making it versatile for different tuning needs. It includes a 0 to 5 voltage analog output, allowing integration with data loggers and engine management systems for advanced monitoring and analysis. The Bosch UEGO sensor ensures rapid response times and high accuracy, critical for performance tuning.

Included with the gauge are black and silver bezels along with black and white faceplates, providing customization options to match your vehicle's interior. Note that the controller gauge and hardware are sold without the wideband sensor, and no free air sensor calibration is required with approved sensors, simplifying the setup process.
