AEM's New X-Series Wideband Now Available with OBDII Connectivity!

AEM's X-Series Wideband UEGO AFR Sensor Controller Gauge with OBDII integration. This 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. It has been verified to work with HPTuners, EFILive and DashDaq, and other systems are being validated.

The X-Series Wideband AFR OBDII Gauge includes an OBDII connector and Bosch 4.9LSU sensor that can be free-air calibrated or used with the factory resistor calibration. 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.

The 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. AEMs 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.

Great tool for tuning

Great tool for knowing exactly what's happening in your engine, the output on the OBD2 line is a fantastic addition to this product, no more soldering and messing about with serial cables. Looking forward to play with it much more :)

These gauges are great. Bought 2 of them. My kooks headers already had access on driver side. Added bung on passenger side to have a more complete read on my log with my 430 cubic Hemi 3rd gen. Very quick readouts and the automatic dim feature is awesome
