When tuning an engine, accurate air/fuel ratio data is critical. Running rich can cause a loss of power, and running too lean can result in serious engine damage.

AEM’s Inline Wideband Air/Fuel UEGO (Universal Exhaust Gas Oxygen, “you-way-go”) Controller is perfect for data logging and O2 feedback for programmable engine management systems when a gauge interface is not desired. Simple wiring The controller body is weather proof and can be mounted anywhere in or outside of the vehicle.

Use the Inline Wideband Air/Fuel UEGO Controller for O2 feedback with almost any engine management system. The Bosch 4.2LSU sensor gives the controller its speed and accuracy. It is calibrated at the factory and never requires free air calibration.
