MS3-Pro Evo


The MS3-Pro range consists of the ‘Evo’, ‘Ultimate’ and Plug and Play versions. The wire-in Evo and Ultimate models have drop-on wiring harnesses available from some popular applications such as LS1.

Experience The ULTIMATE.

Developed from the MS3Pro 1st Gen platform, the Ultimate brings NEXT LEVEL capability to MS3Pro’s staggering feature set beginning with a new high quality aluminum IP65 rated, water resistant enclosure.  The Ultimate provides 10 programmable peak and hold injector channels for driving any saturated (high impedance) or peak and hold (low impedance) injectors as well as loads of additional I/O eliminating the need for any other controllers, saving you unneeded complexity and weight.  Out of the box ready for naturally aspirated and boosted applications with on-board 4-bar MAP and barometric pressure sensors, MS3Pro Ultimate was designed to handle your engine combo without breaking a sweat!

No need for a separate data acquisition system, the Ultimate will log up to 32 channels at 200hz. The advanced TunerStudio software provides an intuitive, straight-forward tuning experience for pros and enthusiasts alike with best in class self-learning, self-tuning fuel table strategies to assist you.

The MS3Pro Ultimate is ready to support a wide variety of engines out of the box, with the ability to control anything with up to 10 cylinders with sequential fuel injection, or a four rotor Wankel with separate leading and trailing ignition outputs. Over 50 different ignition modes are supported, from mainstream applications like the GM LS Engines (24x and 58x), Ford Coyote (including VVT), Bosch Motronic, and Chrysler Gen III Hemis!

Experience for yourself why more and more racers and performance enthusiasts are recognizing and choosing MS3Pro over the competition.
