MS3Pro ULTIMATE Standalone EMS – ECU Only




Experience the MS3Pro ULTIMATE by AMP EFI.

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

No need for a separate data acquisition system, the MS3Pro ULTIMATE by AMP EFI will log up to 64 channels, conservatively, 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 by AMP EFI 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 ULTIMATE by AMP EFI over the competition.
