AEM Inline Wideband UEGO AFR Controller
AEM’s Inline Wideband UEGO air/fuel ratio controller delivers all the benefits of AEM’s Wideband Air/Fuel Gauges to those who do not require an additional gauge in their vehicle. It’s ideal for Motorcycle and Powersports applications where adding a gauge is not easily accomplished, and for use on dynamometers and with data loggers.
WHAT IS A WIDEBAND UEGO AIR/FUEL CONTROLLER?
AEM's Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced “You-Way-Go”) Controllers are powerful, cost effective tuning tools that allow users to accurately monitor the Air/Fuel Ratio (AFR) of their engine.
WHY USE A WIDEBAND AIR/FUEL CONTROLLER?
Accurate AFR data is critical when tuning an engine. Running rich (very low air/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air/fuel controllers that can help ensure your vehicle is optimally tuned.
WHAT IS FREE-AIR CALIBRATION?
Some of our competitors require that you frequently perform a free-air calibration procedure to calibrate their O2 sensors. This process involves removing the sensor from the bung while still connected to the controller device, then waving the sensor in the air so it can read atmospheric O2 levels. We use Bosch 4.2LSU sensors in our wideband controllers. Our sensors are individually laboratory-calibrated by Bosch and never require free air calibration!
CAN I CHANGE THE AEM UEGO SENSOR’S CONNECTOR?
No. There is a laser-etched, calibrated resistor in the sensor’s connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor’s output.
The Inline Wideband UEGO Air/Fuel Controller is perfect for data logging and O2 feedback when using a programmable engine management systems, when a gauge interface is not required. It has very simple wiring and is easy to install, and includes a 0-5v output for use with data loggers and most programmable engine management systems. The controller body is weather proof and this unit can be mounted anywhere on the vehicle.
AEM's Inline Wideband O2 air/fuel ratio UEGO Controller is a must if you want to maximize your engine's power and safety. When tuning an engine, accurate air/fuel ratio data is critical because running with too rich of an AFR can cause a loss of power, and running a lean AFR can result in serious engine damage. Use the Inline Wideband AFR UEGO Controller for O2 feedback and data logging with almost any engine management system.
The Bosch UEGO sensor gives the controller its speed and accuracy. It is laboratory calibrated at the factory and NEVER requires free-air calibration when used with AEM wideband air/fuel controllers.
