Show original supplier description
The MS3Pro Mini ECU from AMP EFI is a sleek and compact standalone engine management system, designed to fit in the palm of your hand. It can handle sequential fuel and ignition for engines with up to four cylinders, sequential fuel with wasted spark on six or eight-cylinder engines, or power a 2-rotor Wankel with separate leading and trailing ignition outputs. The MS3Pro Mini requires MS Firmware v1.6.0 or later and TunerStudio v3.2.0 or later for operation. Key features include support for VVT control, idle control with multiple strategies, E85 flex fuel sensor input, boost control, internal high-speed SD card datalogging, and advanced launch control. It also offers compatibility with various wideband O2 controllers and includes features like traction control, VE-based tuning, speed density, and Alpha-N tuning algorithms. The Generic Wheel Decoder allows for support of nearly any standard or aftermarket trigger pattern, and it supports over 50 specialty OEM and aftermarket ignition systems. The MS3Pro Mini is compatible with engines such as Honda B-, K-, and F-series; Mazda B6 and BP series; Mazda MZR / Ford Duratec; Toyota 1JZ/2JZ; and BMW M20/30/50. It can manage 1-4 cylinder engines with distributor, wasted spark, or coil-per-plug ignition, and 6/8 cylinder engines with distributor or wasted spark ignition. The TunerStudio software, included with purchase, provides an intuitive tuning experience with self-learning fuel table strategies.
