Since our doors opened in 1987, our goal has been to create innovative new products that set the standard in the performance aftermarket, delivering the highest level of product integrity, and making advanced technologies accessible to the racing masses. We remain true to this mission today. AEM was the first aftermarket company to create a standalone engine management system that plugged into a vehicle’s factory wiring harness, which dramatically simplified the conversion to programmable EFI for racers by mitigating the need for a bespoke wiring harness. We pioneered the Wideband Air/Fuel Ratio Controller Gauge, creating the fastest-responding, most accurate wideband on the market and making this technology affordable for all racers and enthusiasts. We saw a need for better data visualization and logging for racers, so we created the CD Carbon Digital Dash line that will communicate with virtually any CAN-based device regardless of manufacturer, providing racers with the ability to see and log every channel on their vehicle, regardless of where the data is coming from. We don’t rest on our efforts, and we are always looking for ways to provide more horsepower for your dollar. Whether it’s redesigning our wideband technology to make it the fastest responding in the form of our patented X-Series Wideband so you can get the best possible tune, developing new injector technology for our Water/Methanol Injection Systems that provides more efficient cooling while using less fluid, or providing software that is free and fully enabled (no hidden fees), with no cost for updates. We have a deep appreciation for every racer, enthusiast, and distribution partner who chooses to trust our products and always strive to provide an unparalleled customer service experience. We evolve to meet the support needs of our customers and we put our customers first. We will continue to set the standard for service and support in our industry.
