AEM Digital Serial Data Stream Gauge for EMS V1 & V2 (30-4300)


SKU: AEM-30-4300

AEM’s Serial Gauge plugs into a Series 2 or Series 1 EMS and has the ability to read up to 19 channels simultaneously. Read boost, AFR, EGT, H20 Temp, IAT, RPM, MPH and more on one gauge with an easy to read, digital LED interface! Users can link multiple Serial Gauges together to divide channel monitoring across several gauges.

The Serial Gauge includes a user-selectable LED display allowing users to set vehicle specific limits, warnings, display ranges and operating ranges. This unit runs the standard EMS datastream by default, and includes 12 preset channels and seven user-selectable channels that are custom-configurable through the PC interface, allowing you to monitor practically anything attached to a sensor. AEM’s Serial Gauge includes user-programmable MIN/MAX storage for EVERY channel and records MIN/MAX values even if you are not using the function—if it’s in the stream the gauge records it. Red, yellow and green LEDs and the center three-digit display are fully user-programmable as well, making this a truly custom configurable unit. Users can set alarms for each channel so that when the signal exceeds a value the Gauge notifies you by flashing all LEDs and switching to the channel where the value was exceeded. User-selectable qualifiers eliminate false warning lights, and the unit includes two outputs to trigger ancillary warning lights based on user selectable conditions. The Serial Gauge also includes user-selectable alarm priority in the event multiple alarms sound, allowing you to set alarm readouts in your order of priority.

AEM’s Serial Gauge includes interchangeable silver and black bezels and pin guides, and black and white faces for a customizable look. Quick-Connect technology allows you to install the gauge and connect the wiring separately for easy installation and less chance of damage to the circuit board. The Serial Gauge includes a harness, wiring to connect to the EMS, a daisy-chain adapter for linking multiple gauges to one EMS and software for a trouble-free installation.
