## Overview

The AEM 30-0300 X-Series Wideband UEGO AFR Sensor Controller Gauge is a race-only, high-performance air-fuel ratio meter featuring an 87% larger seven-segment display, ultra-fast response times, and multiple output options including 0-5V, RS232, and CANbus for advanced data logging and feedback control. Designed for professional motorsport environments, it delivers unmatched AFR measurement range and accuracy.

## Description

The X-Series Wideband UEGO AFR Sensor Controller Gauge (PN 30-0300) measures 2 1/16th-inch (52mm) in diameter, and features a modern, visually striking faceplate and new seven-segment center display that is 87% larger than the 30-4110AEM Wideband Gauge's center display. This creates the perception of a larger overall gauge, but in a common 52 mm size for easy mounting. Its slim depth (less than one inch overall) and ultra slim cup depth of .200-inches dramatically increases its application base and potential mounting locations. Note: No warranty for the Lambda Sensor
