AEM’s Universal Programmable Engine Management System adapts to any race 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.

Legal in California only for racing vehicles which may never be used upon a highway.
