rdoactive,
I am using the MSII on my 565" motor. Took a bit of a learnig curve but it is working quite nicely. I did modify the driver circuits for the Low Z injectors, to a more reliable setup. The Megasquirt works much better than the Culter system I ran for years!!
Cost is low, but then you have to figure in the hardware that I already had.

That system has no real advantage over a carb. You are still running a "wet" manifold and not taking advantage of the fuel injectors atomizing cababilities. A multiport setup is the better way to go without question.

Why complicate the issue?

What issue? Or are you saying to just run a carb and be done with it?

Frank

Keep it simple. I just don't see the benefit in complicating things by using that set up except for the fact that it looks cool. It's really not that different in functionality from a holley system out of a Summit catalog as far as I can tell.

I don't see it making any more power than a carburator, when used in a boat.
