AEM X-Series Wideband UEGO OBDII AFR Gauge

AEM Digital Wideband UEGO OBDII AFR Gauge

The World-famous AEM Wideband O2 air/fuel ratio UEGO gauge features a digital LED display and sweeping LED 'needle' that changes colors as AFR changes from rich to lean. A 52mm (2-1/16") gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. All AEM digital gauges feature a 0-5v analog output for use with data loggers and almost any engine management system. Each gauge comes with black and silver bezels and black and white faceplates for multiple color combinations and a custom look (a black Lambda faceplate and black and white Air/Fuel Ratio faceplates).

This X-Series OBDII AFR gauge enables tuners using piggyback modules or open source software to check AFR via the CAN-bus stream that is output by the factory ECU, and to provide the most accurate, safest and powerful tune. It is compatible with DiabloSport in Tune 3, Trinity 2, EFILive, HPTuners and DashDaq software. The gauge includes an OBDII pass-through connector that replaces the traditional AEMnet port fitted into the X-Series 30-0300 gauge.

It comes with a Bosch 4.9LSU sensor, and requires no calibration when fitted, but unlike other models, it can be recalibrated later as the sensor ages. The OBDII output can be used in conjunction with CAN-based OBDII ports (found in 2008 and newer vehicles) to replace (or supplement) a standard O2 sensor with the LSU4.9 sensor for more accurate mixture control. An EFILive Flashscan V2 output is also available via the OBDII connection.

Please note that as the manufacturer cannot control the conditions of installation and use of the sensors, they are not guaranteed.
