AEM 30-4110 Wideband UEGO kit. This kit replaces the classic AEM 30-4100 kit with a new and impRoved LSU4.9 sensor with a faster light-off time and increased efficiency. The AEM wideband UEGO sensor controller accurately monitors Air/Fuel ratios (AFR) during the tuning process to prevent a lean fuel mixture, which could lead to engine damage. AEM has combined a single-channel wideband UEGO controller and gauge display into one unit, providing excellent AFR accuracy and control with an easy-to-read interface. AEM’s Gauge-Type Wideband UEGO 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.
