When you buy AEM electronics, you are getting the finest engineering, highest quality and best value the industry has to offer. The proof is in every product we make. We saw a need for making stand-alone programmable engine management both affordable and available to more racers 15 years ago, and introduced the first plug & play EMS that uses a factory wiring harness and sensors. But as vehicle technology has advanced so has the need for more powerful and capable engine management. Our solution? The Infinity ECU as it delivers all of the features of high-end Motor sports engine management systems on state-of-the-art hardware. It’s powerful enough for professional race teams and affordable enough for privateer racers.
