DIYAutoTune MS3Pro EVO+ ECU

The MS3Pro EVO+ by AMP|EFI represents the latest in next-generation engine management, delivering a powerful suite of tuning and control features for high-performance applications.

Built on the proven MS3Pro platform, the EVO+ is equipped with three AMPSEAL automotive connectors, totaling 92 Pins (31 Inputs and 33 Outputs), an onboard 4-bar MAP Sensor, barometric pressure sensor, and 5 diagnostic LEDs for enhanced monitoring. Engineered for tuners seeking flexibility, precision, and high-speed data logging, the EVO+ offers a robust upgrade path, making it ideal for projects that demand comprehensive control over fuel injection, ignition, and auxiliary systems.
Whether fine-tuning a racing engine or configuring a custom build, the MS3Pro EVO+ combines intuitive TunerStudio Software, self-learning fuel tables, and user-configurable controls to provide a streamlined yet powerful tuning experience. This ECU is designed to grow with your project, delivering professional-grade capabilities and compatibility with an extensive array of engines.

Logic-Level Spark Outputs

The EVO+ model is optimized for use with external ignition modules or “smart coils” equipped with built-in igniters, such as our IGN1A Smart Coils. It provides a logic-level 0-5V signal, offering precise control without generating high heat. This setup is ideal for applications where the coils or ignition components include an integrated ignition driver, such as GM LS, Toyota 1ZZ, VAG COP, etc. It ensures efficient operation without requiring additional heat management.

For those seeking an ECU with built-in ignition drivers, the EVO+ HC model is the perfect choice. This version is designed to deliver high current directly to “dumb” coils, providing powerful spark energy. Ideal for applications where ignition modules lack internal drivers, the EVO+ HC Model ensures maximum spark output for performance and reliability.
