Focussing on manufacturing reliable, affordable and unique products that truly deliver on their promises, AEM is a company that is constantly looking to change the status quo when it comes to automotive electronics. From their boost gauges to their fuel pumps, AEM products are among some of the most sought after electronics, trusted by street enthusiasts and race teams alike.

AEM’s legendary Wideband O2 Air/Fuel UEGO Gauge unites unsurpassed accuracy, speed and control with an easy to read, digital interface. This gauge-type controller features a digital LED display and sweeping LED “needle” that changes colours as AFR changes from rich to lean.

The unit’s 52mm (2-1/16”) gauge housing fits in most gauge pods and can be remotely mounted virtually anywhere. All AEM digital gauges feature a 0-5v analogue output for use with data loggers and virtually any engine management system, such as the AEM EMS or FIC. The Bosch 4.9 LSU sensor has a faster light off time and draws less current than the 4.2 LSU sensor used with AEM’s 30-4100 Wideband UEGO Controller Gauge.

The 4.9 LSU sensors feature the same fuel compatibility as the 4.2 LSU and NEVER require free-air calibration when used with AEM’s 30-4110 Wideband UEGO AFR Gauge.

AEM's World-famous Wideband O2 Air/Fuel UEGO (Universal Exhaust Gas Oxygen, “you-way-go”) Gauge is a must for anyone looking to maximize engine power and safety. When tuning an engine, accurate air/fuel ratio data is critical. Running rich can cause a loss in power, while running too lean may result in serious engine damage. The AEM Wideband O2 Air/Fuel UEGO Gauge features large LED numerals that can quickly alert the user to even a .1 change in air/fuel ratio, providing time to shut down an engine before damage occurs.
