Show original supplier description
The MS3Pro Mini by AMP EFI is a compact standalone engine management system, small enough to fit in the palm of your hand, yet packed with features. Key features include eight saturated injector outputs, four logic-level spark outputs, an integrated 4-Bar MAP sensor, and onboard SD card datalogging, all offered at a significantly lower price point than the MS3Pro EVO+. The MS3Pro Mini is engineered for versatility, effortlessly supporting a diverse range of engine configurations. It can manage sequential fuel and ignition for up to four cylinders, sequential fuel with wasted spark for six or eight-cylinder engines, or power a 2-rotor Wankel engine with dedicated leading and trailing ignition outputs. The system requires MS Firmware v1.6.0 or later and TunerStudio v3.2.0 or later for operation. The ECU is ideally suited for popular engines such as Honda B-, K-, and F-series; Mazda B6 and BP series (including VVT); Mazda MZR / Ford Duratec; Toyota 1JZ/2JZ; and BMW M20/30/50. It also supports 1/2/3/4 cylinder engines with distributor, wasted spark, or coil-per-plug ignition, and 6/8 cylinder engines with distributor or wasted spark ignition. The purchase includes a TunerStudio registration code, with options for an 8ft flying lead harness, USB adapter, and tuning cable. Purchases of the ECU-ONLY version do not include these accessories.
