AEM X-Series OBDII Wideband UEGO AFR Sensor Controller Gauge (PN 30-0334) allows engine tuners to monitor air/fuel ratio (AFR) readings through a vehicle's factory CAN-bus system, for improved tuning accuracy and safety. Compatible with various tuning software including EFILive and HPTuners, the gauge includes an OBDII pass-through connector and a Bosch 4.9LSU sensor for AFR measurement. The sensor can be calibrated freely in open air or by using the vehicle's existing resistor calibration. Users can also add wiring to output data to a data logger.

Unlike the traditional AEMnet output featured in previous models, this gauge utilizes an OBDII CAN-bus output. This simulates an additional ECU signal when connected to the vehicle's OBD-II port. AEM's default OBDII CAN address typically functions with most vehicles. However, the gauge allows users to program a custom ECU address, parameter identification (PID), message identifier, and bit rate if needed.

Employing AEM's patented X-Digital technology, the X-Series gauge boasts the fastest response time among tested wideband AFR controllers. This ensures accurate reading of even the slightest AFR fluctuations due to minimal signal loss. Faster response time translates to improved wideband feedback control, ultimately leading to safer and more precise engine tuning.
