AEM X-Series UEGO Wideband Ctrlr 30-0310


AEM Inline Wideband UEGO Controller
with Wideband Air/Fuel Sensor

The AEM Inline 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 AEM Inline Wideband UEGO is a must for anyone using an engine management system and does not want to add another gauge in their car for air/fuel ratio. Air/Fuel ratio is one of the most important things to know when tuning your engine. Running rich can cause you to lose power, running too lean can result in serious engine damage. The Inline UEGO can be easily tied in to almost any engine management system to be used for O2 feedback. AEM no longer sells EMS' with a built in UEGO, and we suggest this as the alternative to those looking to have a UEGO to go along with their EMS. A Bosch 4.9LSU sensor gives the Inline UEGO its speed and accuracy, and is the same base sensor used in many OEM applications today. The unit is enclosed in a weatherproof housing, allowing it to be mounted in the engine bay without worry.
