DIYAutoTune MS3Pro EVO+ HC ECU

The MS3Pro EVO+ HC (High Current) 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+ HC 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+ HC 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.
High Current Spark Outputs
The EVO+ HC model is equipped with built-in ignition drivers, providing High Current (HC) Outputs, also known as “direct drive” outputs. These outputs are specifically tailored for “dumb coils” that lack built-in ignition drivers. By supplying current directly to the coil, high current outputs eliminate the need for external igniters, delivering powerful and consistent spark energy. This configuration is ideal for engines requiring high-energy ignition, as the ECU directly manages spark energy for superior ignition control without additional components.

For applications using Coils with built-in igniters like the IGN1A Smart Coils, GM LS, Toyota 1ZZ, VAG COP, etc. may consider the EVO+ Model, which is optimized for use with 5v logic-level spark outputs.
