AEM Digital Wideband UEGO AFR Gauge - Without Sensor

AEM Digital Wideband UEGO air/fuel ratio (AFR) controller and gauge in one, sold without the wideband sensor for users who already have one. The digital LED display and sweeping LED needle change color as AFR moves from rich to lean, giving accurate tuning feedback. A 0-5V analog output (2010-2020 AFR range) feeds data loggers and engine management, and the sensor never requires free-air calibration. 52mm (2-1/16in) housing.
