MS3Pro Mini ECU Standalone Engine Management System

The AMP EFI MS3Pro Mini ECU is a compact, palm-sized, wire-in standalone engine management system engineered for performance applications where space is at a premium. It provides the core MS3Pro feature set, including 8 high-impedance saturated injector outputs, 4 logic-level spark outputs, and onboard sensors for 4-bar MAP and barometric pressure. Data logging is handled by an internal SD card, and the system offers CAN/RS232 connectivity for tuning via TunerStudio. This versatile ECU supports a variety of engine configurations, including sequential fuel and ignition for many 4-cylinder engines, sequential fuel with wasted-spark for 6-8 cylinder engines, and separate leading/trailing ignition outputs for 2-rotor Wankel engines. Its flexible I/O set includes 2 conditioned cam/crank inputs, 3 digital inputs (2 high-frequency capable), 4 general-purpose analog inputs, dedicated sensor inputs (CLT, IAT/MAT, TPS), and outputs for fuel pump control and general-purpose PWM control. The MS3Pro Mini is compatible with a wide range of trigger patterns and over 50 OEM and aftermarket ignition systems. Key features include VE-based tuning, speed density/Alpha-N/MAF algorithms, individual cylinder fuel and spark trim tables, staged injection control, boost control, traction control, advanced launch control, and nitrous control strategies. It requires MS Firmware v1.6.0 or later and TunerStudio v3.2.0 or later, with a license for TunerStudio included. The MS3Pro Mini is designed for custom wiring, engine swaps, and motorsports builds, offering a powerful solution for precise engine control.
