AEM Electronics inline wideband UEGO controllers give all the benefits of the AEM Electronics 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. With simple wiring and easy installation, the weatherproof controller 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.
