The AEM X-Series OBDII Wideband AFR Gauge is a digital UEGO sensor controller that delivers ultra-fast, high-fidelity air/fuel ratio readouts and OBDII CAN-bus output for modern vehicles. Patented X‑Digital technology minimizes deadtime for precise transient response, and the package includes a Bosch 4.9LSU sensor, wiring, OBD2 cable and bezel. Programmable OBD addressing and 0–5V or RS232 logging outputs make it tuner-friendly for 2008+ OBDII systems.
X-Series Wideband UEGO AFR Sensor Controller Gauge with OBDII Connectivity. Includes: X-Series Wideband Controller Gauge, Bosch LSU 4.9 Sensor, Wiring Harnesses, Black Bezel, Black AFR/Lambda Faceplate, OBD2 Cable & O2 Sensor Bung
OBDII Wideband Gauge for 08+ Vehicles
Features & Benefits
X-Series Wideband UEGO AFR Controllers Gauge were fastest responding wideband air/fuel ratio controllers in an independent test vs. 17 competitors wideband AFR controllers
0-5V & RS232 output for data logging and feedback control, AEMnet (CANbus) for data logging and daisy-chaining multiple controllers up to 16 cylinders

Additional wiring for a 0-5v or RS232 Serial output can be added by the user for outputting to a data logger. This OBDII pass-through capability replaces the traditional AEMnet stream available in the 30-0300 X-Series Wideband AFR Gauge Controller.OBDII CAN-bus OUTPUTThe OBDII output simulates an auxiliary ECU signal when plugged into a vehicle's OBD port, which requires a unique address from the other ECUs already on a vehicle's network.
PATENTED X-DIGITAL TECHNOLOGY - It's The FastestX-Series Widebands are the fastest responding wideband air/fuel ratio controllers in independent testing against 17 other wideband UEGO air/fuel controllers.* The controller's high speed, patented, X-Digital technology (Patent 9,575,030) ensures no loss of signal fidelity and full transient response, making it able to identify the slightest fluctuations in AFR and output them in full value.
AEM's default OBDII CAN address will work with most popular vehicles and adjustments should not be necessary. However, AEM has provided OBDII address programmability through the buttons on the gauge face if a different address other than the default address is required, allowing users to program ECU #, Parameter Identification (PID), Message Identifier, and Bit Rate.
The 30-0334 X-Series OBDII Wideband Gauge is validated to work with DiabloSport in Tune 3, Trinity 2, EFILive, HPTuners and DashDaq software.The X-Series Wideband AFR OBDII Gauge includes an OBDII pass-through connector and 4.9LSU sensor that can be free-air calibrated or used with the factory resistor calibration.
AEM's X-Series OBDII Wideband UEGO AFR Sensor Controller Gauge (PN 30-0334) provides tuners who are using piggyback tuning modules or open source software with the ability to view AFR through the factory CAN-bus stream that is output by the factory ECU, and deliver the most accurate, safe and powerful tune.
WHY RESPONSE TIME MATTERS - Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM's Wideband Controllers with X-Digital technology reduce deadtime and can improve the performance of your vehicle through more accurate AFR tuning.
