What do I need to lookup and research as far as additional stuff I'd need to add to a pre-assembled ms2 board... Are all the injector drivers and coil stuff onboard and just need to wire it up?

I dont mind doing the research at all, I am confident in my soldering as far as that stuff goes, just need to know what I am researching.

That being said I will go read megamanual and msextra manual. I think thats the problem with megasquirt, its not real obvious what I am going to need, what firmware, what is extra, etc. MS3 looks pretty impressive, but with its release date pretty much TBA, I dont know if I can wait around =)
