I have looked at megasquirt previously but found it confusing as there are so may hardware and software versions floating around.

I want to use megasquirt to control the ignition and fuel on a V6 BOB Cosworth engine. I am thinking about the Megasquirt 3.57 main board with the MS2 daughterboard with the MS3X expansion board running some version of the megasquirt firmware.

I was wondering if anyone more knowledgeable than me on the megasquirt could advise which version would best suit my application.
