Product details
The AEMnet CAN bus gauge connects to AEMnet-equipped devices through a 4-pin DTM connector and displays data in either US or Metric units. View multiple data channels from an Infinity ECU, Series 2 or EMS-4 standalone, view AFR or Lambda from X-Series Wideband Controllers or 4-Channel Wideband Controllers, or view vehicle speed and acceleration from a Vehicle Dynamics Module (see available Channels List). Users can program which available channels they want to see on the display, choose between displaying Lambda or AFR and clear peak values for channels by using the buttons on the faceplate. The X-Series AEMnet CAN bus Gauge has a bright four-digit LED display that is 87% larger than our original digital gauges and provides better readability. A sweeping LED "needle" lines the edge of the gauge face for quick reference. A 33% overall increase in the gauge face display makes it easier to see at a glance. X-Series Gauges come with a black bezel and faceplate, and an optional silver bezel/white faceplate accessory kit is available (PN 30-0312-ACC, sold separately). Despite the larger display, X-Series Gauges are contained in a standard 2-1/16th-inch (52mm) diameter housing for mounting in a standard gauge pod. Thanks to an advanced single board design, X-Series Gauges have an incredibly slim overall depth of under 0.825", with a cup depth of only 0.200." This shallow cup depth allows X-Series Digital Gauges to be mounted practically anywhere. AEM's X-Series AEMnet CAN bus gauge (PN 30-0312) displays multiple channels of data from AEMnet CAN bus equipped devices-it's like having multiple gauges in one display!
