**For use with SCT devices, if using HPTuners look into the X-Series wideband also listed on our site**
A 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 its single-channel wideband UEGO controller and gauge display into one unit, uniting unsurpassed 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.
