MS3Pro Mini ECU

Description

Introducing the MS3Pro Mini by AMP EFI

MS3Pro Mini by AMP EFI, the sleek and compact addition to our MS3Pro Wire-In ECU product line. This new ECU is designed to fit in the palm of your hand! Tailored for engines with up to eight cylinders, it boasts the same high-quality features as its larger counterpart, the MS3Pro EVO, including eight saturated injectors, four spark drivers, an on-board 4-Bar MAP sensor, barometric pressure sensor, and on-board SD card datalogging – all at approximately half the price of the Evo!

The MS3Pro Mini by AMP EFI is engineered to effortlessly support a diverse range of engines straight out of the box. Whether running sequential fuel and ignition on engines with up to four cylinders, sequential fuel with wasted spark on six or eight-cylinder engines, or powering a 2-rotor Wankel with separate leading and trailing ignition outputs, this versatile ECU is up to the task.

MS3Pro Mini Requires MS Firmware v1.6.0 or later and TunerStudio v3.2.0 or later.
