AEM’s 4-Channel Wideband UEGO Controller is a must for anyone using an engine management system or data logger to monitor and/or tune individual cylinder AFR to for maximum engine performance and reliability. It allows users to simultaneously monitor individual cylinder Air/Fuel Ratios (AFR) on up to four cylinders, and can monitor 8 individual cylinders with the addition of a second unit (up to 12 cylinders by daisy chaining three units together). If you want the absolute best tune and most accurate engine air/fuel ratios there is no substitute for using the 4-Channel Wideband UEGO AFR Controller.
CAN-BUS or Analog Outputs for Datalogging:
Since not all programmable engine management systems can accept four separate inputs, AEM's 4-Channel Wideband UEGO Controller includes a CAN-BUS datastream output that provides users with the ability to datalog for each individual cylinder without tying up all of the ECU's channels. The unit also includes four 0-5v analog outputs for each AFR channel.
Weather-proof/Shock-proof Housing, Harness, and Communication Connections:
The 4-Channel Wideband UEGO Controller is housed in a weather-proof housing that repels dirt, dust and debris, and is vibration resistant. Mount it virtually anywhere!
Back Pressure Compensation for Accurate, Pre-Turbo, Individual-Runner AFR Readings:
By monitoring exhaust backpressure, AEM's 4-Channel Wideband UEGO Controller is able to consistently deliver accurate AFR readings that are unaffected by pre-turbo back pressure. This eliminates the need for averaged post-turbo AFR readings on turbocharged applications and allows users to extract peak performance from their engines.
