Megasquirt 2 V3.57 is a standalone engine management controller.
Compared to the MS2 V3, the V3.57 is a production built unit with surface mount components that are not hand placed. The V3.57 board does not have a prototype area like the V3 so if you are looking for lots of features and functions, the MS3 with Expander may be a better choice for you.
In basic form it is capable of running both fuel and Ignition. With additional options it turns into a very powerful engine performance modifier. Don't be fooled by the affordable nature of these controllers. They are small and powerful. They can run most everything on 4 wheels whether that's your lawn mower, an Air-cooled VW, Water cooled Jetta, Blown V8 or anything in between.
Below is a list of options and extra that can be purchased along with your controller. If you have any question please send me an email and I can build a custom quote or help you decide which options are best for your install.
