I hear all this talk about Megasquirt, and I assume it's an alternative to the D-Jet system, but I don't know anything about it. I have a 1975 164 (a 49-state, non-catalyst version), and it could use a better alternative F.I. system (for quicker starts, better fuel mileage, more power, etc.).
Is there a book or manual that explains Megasquirt, describes what it can do, and/or how I could design it's mapping (what it would require). I'm pretty handy with tools and electrical fabrication (even a little "descrete component" electronics a la Heathkit projects of the '60's and '70's), but I don't have access to a dynamometer or anything "big bucks" like that.

Even some introductory remarks to tell me exactly what this system can replace in my car would be appreciated.

Thanks.
