It 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. The 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.
