Speed Density SFI -possible?

[orlin steven jared]

Hi All,


I finally read some info on fuel injection systems (the basics)
in the March issue of Car Craft, and I have a question.

It seems that only MAF based systems use sequential port injection,
and the speed density systems use batch fire injection.   At least,
that's the way the article makes it look.   I was wondering what the
reason for this is, and if you can make up a system (without much
difficulty) for SFI with a speed density system.

For my future project (fuel injected BBC, homemade manifold), it seems
that a speed density system would be the best choice, but SFI instead
of batch fire would also seem to be an added bonus.

BTW, has anyone compiled information on tunability of S-D systems?
I couldn't find anything on the web page.


Thanks,


Steve
