MS3Pro EVO Standalone ECU

The MegaSquirt MS3Pro EVO is a highly configurable standalone engine management system (EMS) that provides professional-level control for a wide variety of engines. It evolves from the original MS3Pro with enhanced I/O capabilities and integrated sensors, including an on-board 4-bar MAP sensor and a barometric pressure sensor. Key features include VE-based tuning, which simplifies calibration by reducing the need for numerous correction tables, alongside support for Speed Density, Alpha-N, and blended algorithms. It offers up to 12 sequential saturated fuel injector outputs and up to 8 sequential logic-level ignition outputs, supporting various ignition modes like wasted spark and coil-per-plug. The MS3Pro EVO is capable of controlling engines with up to 10 cylinders or even four-rotor rotary engines, with support for over 50 ignition modes and a generic wheel decoder for compatibility with diverse trigger patterns. It also includes advanced features like individual cylinder fuel and spark trim tables, dual fuel support, and 4-channel VVT control. For data logging and diagnostics, the MS3Pro EVO features internal high-speed SD card logging up to 64 channels at 330Hz, eliminating the need for an external datalogger. It also boasts multiple strategies for traction control, boost control, launch control, and advanced engine protection features, including intelligent knock detection and fault mode strategies. The system is equipped with 5 diagnostic LEDs for quick visual feedback. This product is sold for OFF ROAD RACE-ONLY, ground-vehicle use only. Aftermarket EFI/EMS systems are not for sale or use on pollution-controlled vehicles. Alteration of emission-related components constitutes tampering under US EPA guidelines and may lead to substantial fines and penalties.
