AEM Digital Wideband UEGO Air-Fuel Ratio Gauge.

Is your car running a bit rich and generally down on power? Or maybe you fitted new injectors and you just can’t get the air-fuel ratio right, or maybe you just want to keep an eye on your air fuel ratio while you roam the streets or are racing on the track. If you answered yes to any of these you need the AEM UEGO wideband gauge installed in your car.

Installation is super simple, the sensor needs to find its home in your exhaust (check the AEM link below for sensor placement and angle advice) and the gauge comes with a wire harness that is plug an play – minus the handful of wires that need to be wired up for power. This gauge also supports data logging of the fuel ratio – see the AEM link below for how (requires RS232 data plug for connection). If you have a tunable ECU with datalogging already this gauge can be wired to be datalogged through your ECU. https://www.aemelectronics.com/files/instructions/30-4110%20Digital%20Wideband%20UEGO%20Gauge.pdf

The sensor’s sensitivity comes from the Bosch 4.9 LSU sensor. This sensor does not require air to air calibration pre-use unlike other wideband sensors due to factory-based free air calibration. Sensor read performance is also high on the list of “the best wideband” sensors – check this video for a performance comparison: https://www.fordmuscle.com/archives/2007/06/WidebandShootout/index2.php
