AEM’s 4-Channel Wideband UEGO Controller is a powerful, cost effective tuning tool that allows users to monitor the Air/Fuel Ratio (AFR) of up to 4 individual cylinders simultaneously. This unique controller features an optional exhaust back pressure compensation* kit to correct AFR readings of Wideband sensors mounted pre-turbo. The system includes stainless steel bungs specially designed for use in individual port applications which feature a finned stand-off design which both cools the sensor body and minimizes exhaust port restriction. The 4-Channel Wideband UEGO controller is ideal for datalogging, engine management systems or racing applications where individual cylinder trims are needed. The system features simple wiring and installation with 0-5v analog outputs for each AFR channel as well as a CAN datastream output. The controller is shock & weather proof and can be mounted anywhere in or outside the vehicle.
