Overview

The AEM Wideband UEGO Air/Fuel Ratio Gauge is a performance tuning tool that integrates a wideband O2 controller and gauge into one 52mm (2-1/16") unit. It features an easy-to-read digital LED display and a sweeping LED needle that shifts color to indicate real-time AFR changes.

It uses a Bosch 4.9 LSU sensor, which provides fast light-off times and is individually laboratory-calibrated, requiring no free-air calibration.
Show original supplier description
The AEM Wideband UEGO Air/Fuel Ratio Gauge serves as an essential monitoring and tuning tool for high-performance engines. By combining a wideband controller and display into a compact 52mm housing, it allows users to precisely track air/fuel ratios to prevent engine damage from lean conditions or power loss from rich conditions. The unit provides a 0-5v analog output for integration with data loggers and most engine management systems. Technical performance is driven by the included Bosch 4.9 LSU sensor. This sensor is factory laboratory-calibrated and eliminates the need for manual free-air calibration. The gauge face features a digital LED readout and an outer ring that acts as a sweeping needle, changing colors as the mixture shifts. Users can customize the look using the included black and white faceplates along with black and silver bezels. This product is designated for closed-course competition use only and is not intended for street use. Installation and use of this product may be illegal nationwide under the Federal Clean Air Act. Modifying the sensor connector is strictly prohibited, as each sensor includes a laser-etched resistor calibrated specifically to its individual sensor body; altering this will invalidate the output. The gauge is a universal-fit component for performance tuning applications. Buyers should be aware that this unit is a dedicated tool for engine diagnostics and optimization, and it is not street legal in many jurisdictions.
