Description

The AMP EFI MS3Pro Mini is a compact standalone EFI controller engineered to manage a wide range of engines. This versatile ECU supports sequential fuel and ignition on engines up to four cylinders, sequential fuel with wasted spark on six or eight-cylinder engines, and can power a 2-rotor Wankel with separate leading and trailing ignition outputs. It boasts the same core features as larger MS3Pro models, including eight saturated injector outputs that can be repurposed as high-current or PWM outputs, four logic-level spark outputs, an onboard 4-bar MAP sensor, and an onboard barometric pressure sensor. High-speed data logging is available via an internal SD card.
