AEM X-Series Digital Boost Pressure Gauges include technological features that make them easier to use, including two faceplate buttons for peak/recall, standard or metric center LED readout with a sweeping LED needle, and user-selectable threshold warnings. The gauges are AEMnet CANbus-enabled so they can be daisy-chained together for use with the AEM Infinity ECU, Series 2 EMS, AQ-1 Data Logger, or a 3rd party EMS/logger that accepts AEMnet, and they also output 0-5V analog for data loggers and engine management systems.
