AEM 30-0311 – X-Series OBDII Digital Gauge
Product Overview
The AEM 30-0311 is a plug-and-play OBDII display from the X-Series range. It pulls power and data through a single OBDII (ISO 15765 CAN) cable and shows live ECU parameters on a large four-digit LED screen. An integrated DTC function lets you read and clear trouble codes, so one slim unit can replace several traditional gauges.
Key Features
-
One-cable installation – power and data via the supplied OBDII harness; no extra sensors or wiring.

Selectable data pages – cycle through RPM, boost/MAP, EGT, IAT, TPS, speed, AFR, battery voltage, fuel level, and more (availability depends on your ECU).

-
Oversized LED display – central digits are 87% larger than previous AEM gauges; a 24-LED outer ring acts as an analog sweep.
