AEM’s 4-Channel Wideband UEGO Controller (PN#30-2340) allows users to simultaneously monitor individual cylinder Air/Fuel Ratios (AFR) on up to four cylinders, and can monitor up to 8 individual cylinders with the addition of a second unit. The AEM 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 increase performance and reliability.
UNMATCHED CONTENT AND ACCURACY
AEM has engineered several features into the 4-Channel Wideband UEGO Controller that provide unmatched accuracy and feature content:
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. Sensors can be mounted pre-turbo when used with AEM’s optional Exhaust Back Pressure kit (PN#30-2064). This eliminates the need for averaged post-turbo AFR readings on turbocharged applications and allows users to extract peak performance from their engines.
Designed to Withstand Extreme Temperatures – AEM’s 4-Channel Wideband UEGO Controller uses specially-designed, stainless-steel sensor mounting bungs to withstand the extreme temperatures of pre-turbo exhaust ports. The fins on the bung reduce the temperature of the sensor body to extend sensor life, and the extended bung length allows only the sensor tip to protrude into the exhaust flow to minimize flow restrictions.
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.
Laboratory-Calibrated Sensors –
Bosch 4.2LSU sensors are laboratory calibrated at the factory. They deliver unsurpassed accuracy and NEVER require free-air calibration when used with an AEM controller.
Channel Status and Error Lights –
AEM’s 4-Channel Wideband UEGO Controller includes green and red LED lights for each channel that provide immediate reference to system status or to indicate an error. The LEDS provide immediate confidence that the system is operational and helps eliminate trouble shooting if an error occurs.
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!
