The AEM Digital Wideband UEGO Air/Fuel Ratio (AFR) Gauge (30-4110) is a high-precision tuning tool that combines a wideband controller and a digital display into a single standard 52mm (2-1/16") housing. This unit provides real-time monitoring of air/fuel ratios, allowing tuners to optimize engine parameters for maximum power and efficiency while preventing lean conditions that can lead to engine failure.

Equipped with the Bosch 4.9 LSU wideband sensor, the 30-4110 is laboratory-calibrated to deliver immediate, accurate readings without the need for manual free-air calibration. The gauge features a high-contrast digital LED display flanked by a sweeping LED "needle" that changes color based on the AFR range. For data logging and engine management integration, it includes a 0-5v analog output (10-20 AFR range).
