please inform me about pro's/con's of dsmlink

[FattyBoomBatty]

I am going to use a 1G fwd manual trans wiring harness and install multiport FI on my car. I have decided this will be easier than using megasquirt, which i'll sell to a volkswagen buddy of mine.

I'd like to know a few things:

What year/type of ecu will I need?

What exactly is a DSMLink?

How does it "plug in" or whatever it does when you install it?

I will use a GM maft setup - I've seen it used with that and it's easy.

Are there any other good things to know when I do this? like What will I do for the CAS? is that just a hall sensor? Should I mate a CAS to a stock dist. and make that work? I'm sure it could be done. And What should I do for coils, can I make coil on plug work or single coil?

Thanks!
Andrew
