PRODUCT DESCRIPTION
AEM 30-0311
AEM X-Series OBDII Gauge Black Bezel & Faceplate
AEM’s X-Series OBDII Gauge (PN 30-0311) puts multiple channels of data at your fingertips by reading the CAN bus stream from your vehicle’s OBD Port and transmitting those channels to the gauge’s display. It reads Diagnostic Trouble Codes (DTCs) and allows you to clear them. Installation is as simple as plugging the gauge into your vehicle’s OBDII port via the supplied connector! Because the X-Series OBDII gauge reads OBDII parameters transmitted over the vehicle’s CAN data stream, it will only work on 2008+ model year vehicles.
EASY TO USE
Use the “Page” button on the gauge face to scroll through the available data channels transmitted through the OBD port. Possible channels are listed below, which can include IAT, EGT, RPM, Ethanol %, MAF, Fuel Pressure, Manifold Pressure, Boost, TPS, Vehicle Speed, Lambda and more (channel availability is ultimately dependent on channels programmed to broadcast by the vehicle manufacturer).
READ & CLEAR TROUBLE CODES
The “DTC” button tells the gauge to search for trouble codes and will report any stored DTCs, allowing you to research them and determine the course of repair. This button also allows users to clear DTCs once the issue has been resolved.
The X-Series OBDII gauge has a bright four-digit LED display that is 87% larger than our original digital gauges, providing better readability. A sweeping LED 'needle' lines the edge of the gauge face for quick reference. An overall 33% 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 accessory kit is available with a silver bezel and white faceplate (PN 30-0311-ACC, sold separately).
Despite the larger display, X-Series Gauges are housed in a standard 52mm (2-1/16") diameter housing for mounting in a standard gauge pod. Thanks to an advanced single board design, X-Series Gauges have an incredibly shallow overall depth of less than 0.825”, with a cup depth of only 0.200”. This shallow cup depth allows X-Series digital gauges to be mounted practically anywhere.
