AEM UEGO Replacement Sensor w/ Connector for Bosch LSU 4.9

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. * Ideal AFR monitoring tool for EFI and carbureted applications, and engine dynamometers * Does not oscillate AFR reading like narrow band sensors * No laptop required for monitoring! * Bosch sensor included * Accurate to 0.1 AFR * Reads in AFR or Lambda via a switch in back of gauge housing * 24 Color-coded LED display lights provide immediate reference to engine?s air/fuel ratio (AFR) or Lambda ratio * Integrated three-digit display reveals AFR or Lambda in real time * User-programmable 0-5v analog output included for use with data loggers and virtually any engine management system * Serial data stream included for output of AFR (RS 232)
