AEM Electronics Tuning Accessories

Tuning Accessories are parts that are optional or needed to be used with different types of tuning platforms.  These may be in the form of AFR cords, ECU cables, fittings, dongles, etc.  Also can be handheld scanners or other equipment that is needed when tuning a vehicle.


When racers and enthusiasts buy AEM performance parts, they are getting the finest engineering, highest quality and best value our industry has to offer. Look no further than our products for proof. AEM created the first stand-alone programmable engine management system that uses a factory wiring harness, and was the first to introduce a gauge with a built-in wideband UEGO controller and gauge readout in one unit! More recent innovations include our Water/Methanol Injection Systems, which provide the ultimate combination of performance, quality and value for gas and diesel race vehicles, a complete line of digital and analog display gauges, and the X-WiFi module, which allows users to view critical exhaust data wirelessly on virtually any WiFi enabled device. In addition, the recent release of AEM’s Series 2 EMS with AEMTuner interface software represents a major evolution in features and ease of use from the original.
