AEM Electronics 30-0302 Details
AEM’s 30-0302 X-Series 100-300 F/40-150C Digital Gauge combine incredible looks, increased readability and a multitude of new, easy-to-use features! It is a must for users who want highly accurate water, transmission and/or oil or temperature readouts in their high-performance vehicle.
NOTE: The 30-0302 comes with a black bezel and black water temperature faceplate. You will need to purchase the optional 30-0302-ACC accessory kit to get the silver bezel, white water, transmission and oil temp faceplates, and black transmission and oil temperature faceplates. Each faceplate is double-sided with standard PSI on one side and metric BAR on the other. The calibration for standard or metric display is easily performed using the buttons on the face of the gauge.
EASIER TO READ
Visual improvements include a bright center LED display that is 87% larger than our original digital gauges and provides better readability. A sweeping green 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.
EASIER TO MOUNT
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.
SMARTER INTERFACE
X-Series Digital Gauges include new technological features that make them easier to use. Two buttons on the faceplate deliver programmability for peak/recall, standard or metric center LED readout and sweeping LED needle, and user-selectable threshold warnings. The gauges are AEMnet CAN-bus enabled, so they can be daisy-chained together for use with the Infinity ECU, Series 2 EMS, AQ-1 Data Logger, or 3rd party EMS or logger that accepts AEMnet. 0-5V analog outputs are also included for inputting into data loggers and engine management systems.
