MS3 Pro EVO Setup with 8ft bare ended loom - £1145 inc UK postage (£5 more for EU)

The MS3-Pro is basically a sealed MS3X setup, so it's ready to support a wide variety of engines out of the box, with the ability to anything with one to eight cylinders with sequential fuel injection and sequential 'coil on plug' ignition, a V12 with sequential fuel (An MS3X can go up to a V8 as standard) and wasted spark ignition, 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 LS1, Bosch Motronic, and Chrysler Gen III Hemis to unusual modes like Renix Jeeps and the Suzuki Swift GTI.

The MS3-Pro's packaging is where it differes from the standard MS3X setup. Instead of the industrial looking split aluminum case and D-sub connectors, the MS3-Pro uses a sealed high temperature nylon case for light weight and compact size, and heavy duty AMPSEAL connectors. This provides a compact and sealed enclosure protecting the sensitive internals from the elements. The MS3-Pro's design keeps the heat generated to a minimum, allowing it to use a lighter plastic case instead of a metal heat sink.

This package includes the MS3-Pro EVO, all tuning cables, software and manual on a USB drive, and 8' wiring harnesses.

Note that the MS3-Pro uses an built in 4 BAR MAP sensor as standard.
