AEM’s X-Series Inline Wideband UEGO Air/Fuel Ratio Controllers are built upon unique, patent-pending X-Series digital technology that makes them the fastest responding wideband air/fuel ratio controllers in independent testing against 17 other wideband UEGO air/fuel controllers*. The X-Series Wideband UEGO Air/Fuel Ratio Controller replaces the popular 30-2310 Inline Controller.

X-Series Inline Wideband UEGO Controller features a weather-resistant, low-profile enclosure with status LEDs. It is ideal for users who do not need a gauge display and want the fastest response time when data logging or for feedback control when tuning with an engine management system.

The X-Series Inline Controller includes a 0-5v and RS232 Serial Port output for feedback control and data logging, and an AEMnet (CANbus) output for data logging and daisy chaining multiple X-Series Controllers together (up to 16 cylinders) for recording AFR in multiple cylinders. It supports vehicle/system voltages up to 16V, and can be used on EFI or carbureted applications, and dynamometers in applications using gasoline, methanol, ethanol, Diesel, propane and CNG..
