If you have a Powerlogger, this can be connected to monitor and datalog air/fuel ratio.
The Inline Wideband UEGO gives all the benefits of the AEM Wideband Air/Fuel Gauges to those who do not require or want an additional gauge in the car. Perfect for datalogging, engine management systems or racing applications where a gauge is not desired. Simple wiring and installation, the controller is weather proof and can be mounted anywhere in or outside the vehicle.
The system features a Bosch sensor with an accuracy of .1 AFR, making it among the fastest and most accurate widebands available. Quick and easy installation and use for applications that do not require a display gauge.
