The AEM X-Series OBD2 Digital Datastream Gauge (PN 30-0311) is a powerful tool for vehicle monitoring, putting a wealth of data directly at your fingertips. By tapping into your car’s OBDII port and reading the CAN bus stream, this gauge displays multiple channels of crucial engine and vehicle information on a bright, easy-to-read digital display. Beyond just displaying data, it also empowers you to read and clear Diagnostic Trouble Codes (DTCs), making it an invaluable asset for both performance enthusiasts and everyday drivers. Installation is incredibly straightforward, requiring just a simple connection to your vehicle’s OBDII port using the included connector. It’s important to note that because this X-Series OBD2 gauge relies on OBDII parameters transmitted via the vehicle’s CAN datastream, it is compatible with 2008 and newer model year vehicles.
Effortless Data Access and User-Friendly Operation
Navigating through the available data channels is intuitive with the ‘Page’ button located on the gauge face. Simply press to scroll through a comprehensive list of parameters broadcast through your vehicle’s OBD port. The specific channels available will depend on what data your vehicle’s manufacturer has programmed to transmit, but commonly accessible channels include Intake Air Temperature (IAT), Exhaust Gas Temperature (EGT), RPM, Ethanol Content (%), Mass Air Flow (MAF), Fuel Pressure, Manifold Pressure, Boost Pressure, Throttle Position Sensor (TPS), Vehicle Speed, Lambda, and many more. This wide range of potential data points allows for a detailed understanding of your vehicle’s performance and health.

Read and Clear Diagnostic Trouble Codes (DTCs)
The AEM X-Series OBD2 Digital Datastream Gauge goes beyond just displaying live data; it also functions as a basic diagnostic tool. With the dedicated ‘DTC’ button, the gauge can scan your vehicle’s computer for stored trouble codes. If any DTCs are present, the gauge will display them, allowing you to research and understand the potential issues affecting your vehicle. Once the underlying problem has been addressed and resolved, the same ‘DTC’ button provides the functionality to clear the stored codes, turning off the check engine light and confirming the repair. This feature saves time and money by allowing users to address minor issues themselves and gain valuable insight into more complex problems before seeking professional help.

Enhanced Visibility and Sleek Design
The X-Series AEM OBD2 Gauge (PN 30-0311) boasts a significantly improved display for optimal readability. The bright four-digit LED display is 87% larger than previous AEM digital gauges, ensuring clear visibility at a glance. Complementing the digital readout is a sweeping LED “needle” that lines the edge of the gauge face, providing a quick visual reference to the monitored parameter’s value. The overall increase in the gauge face display by 33% further enhances readability, making it easier to interpret data even in challenging lighting conditions. Each X-Series Gauge comes standard with a black bezel and faceplate for a stealthy, modern look. For those seeking a different aesthetic, an optional silver bezel/white faceplate accessory kit (PN 30-0311-ACC, sold separately) is available.
Despite the larger and more prominent display, X-Series Gauges maintain a standard 2-1/16th-inch (52mm) diameter housing. This industry-standard size ensures straightforward mounting in virtually any standard gauge pod, offering flexibility in placement within your vehicle’s interior. Thanks to an innovative single board design, X-Series Gauges are remarkably slim, with an overall depth of less than 0.825 inches and a cup depth of only 0.200 inches. This shallow depth allows for mounting in even tight spaces, broadening installation possibilities and ensuring a clean, integrated look.
