What is a AEM Engine Managment System or EMS?

AEM’s Universal Programmable Engine Management System adapts to any vehicle using the company’s flying lead wiring harness and sensors (sold separately). In addition to the features found in our Plug & Play EMS, AEM’s Universal EMS also includes 10 independent, built-in peak & hold injector driver channels, direct drive ignition and dual wideband UEGO controllers. Peak & Hold injector drivers enable users to utilize low impedance injectors with a true 4/1 Peak & Hold injector drive circuit. The Direct Drive ignition feature allows users to drive a coil directly from the ECU without the need for an igniter or ignition module, and a wideband UEGO controller is an essential tuning tool that provides a 0-5 signal for monitoring and tuning air/fuel ratios (AFR) on heavily modified high-performance engines.
