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 colors 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 analog output for use with data loggers and virtually any engine management system, such as the AEM EMS or FIC. Instructions for the AEM UEGO 30-4110.
