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 units 52mm (2-1/16) gauge housing fits in most gauge pods and can be remotely mounted virtually anywhere. WHY YOU NEED ONE AFR: The 30-4110 wideband gauge is easy to read, highly accurate, and controls its data by a digital LED display and LED needle that will change colors as the ratios change from rich to lean. Utilizing a 4.9 0258017025 LSU sensor.
