AEM – Digital Wideband Gauge – 30-4110

AEM – Digital Wideband Gauge

The AEM Digital Wideband UEGO Gauge is a tool that measures your engine’s air/fuel ratio (AFR) accurately and quickly. It has a clear digital LED display and a color-changing LED needle that shows if your engine is running rich (too much fuel) or lean (too little fuel).

What is a Wideband UEGO Air/Fuel Controller?

It’s a device that helps you monitor the air-to-fuel mix in your engine for better tuning and performance.

Why Use It?

• Keeps your engine safe and powerful by showing if the fuel mix is right.

• Running too rich wastes fuel and reduces power.

• Running too lean can damage your engine.

• This gauge helps you tune your engine to the best air/fuel ratio.

No Need for “Free-Air” Calibration

Some sensors need you to wave them in the air to recalibrate often. The Bosch 4.9 LSU sensor in this gauge is pre-calibrated and never needs this.

Key Features:

• Clear digital display with color-changing needle (shows rich to lean)

• Fits standard 52mm (2-1/16”) gauge pods or can be mounted remotely

• Comes with black and silver bezels, plus black and white faceplates to match your style

• Bosch 4.9 LSU sensor included for fast and accurate readings

• No free-air calibration needed, ever

• 0-5V analog output for data logging or engine management systems

• Weld-in bung included for sensor installation
