Aem 4 Channel Wideband Uego Controller - Nascar 30-2340-n on 2040-parts.com

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.

Features:

• Allows for monitoring of individual cylinder AFRs for maximum engine power and safety
• Two status lights per sensor for error detection and operating status
• Pair multiple units together for use on 6, 8, 10 or 12 cylinders
• Compact (4.8" x 4.55" x 1.44"), weather & shock proof enclosure
• Accurate to 0.1 AFR
• Bosch Wideband UEGO sensor and stainless weld-in bung included
• No free air calibration required—ever
• AEMnet compatible

Capability:

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!

• Four unique differential analog outputs
• CAN output for use with AEMnet-enabled devices
• Exhaust back pressure compensation to correct AFR readings on wideband sensors mounted pre-turbo (sold separately)
• Two status lights per sensor for error detection and operating status
• Stainless-steel bungs are specially designed for use in individual port applications and feature a finned, stand-off design that cools the sensor body and minimizes exhaust port restriction

Specs:

AEM’s 4-Channel Wideband UEGO Controller kit includes one (1) 4-channel wideband UEGO controller, complete wiring harness, installation instructions and one (1) wideband UEGO sensor with stainless-steel, finned stand-off bung. Additional sensor & bung kits are sold separately (PN#30-2063) for two-cylinder and larger engines. Exhaust back pressure kit (PN#30-2064) is also sold separately.

The 4-Channel Wideband Controller can read the following AFR values (values before exhaust backpressure compensation):

• 0-5V Output/AEMnet Gasoline values from 8.5 to 18:1 AFR
• 0-5V Output/AEMnet E85 values from 5.7 to 11.9:1 AFR
• 0-5V Output/AEMnet Ethanol values from 5.2 to 11:1 AFR
• 0-5V Output/AEMnet Methanol values from 3.7 to 7.8: AFR
• 0-5V Output/AEMnet Lambda values from 0.58 to 1.22
