>Has anyone done any research on the Delco fuel inject..? Also known as DFI.
Seems like it would be simular to a standard TBI setup. The reason I ask is
these setups found on most mid to
late 80's Caddi's are VERY common, I see them on their HT4100 motors, the
little 4.1L V8... Any input...
Thanks

The caddie division uses ecms that carry a gm part no ie, like
the 1227730 they used is the same as a Delco AC GM Buick
Olds Pont 1227730.  Caddie has used several of the ones that
we'll be (hopefully) talking about in the 101 series.

DFI is getting to be rather generic.  Accel is using for their name,
there was an outfit in FL that used it.  Then there was another
in MI, so on+off when ya say DFI depending on who your talking
to might be thinking of something other than delco.

What seems to be an accepted way of decribing a ecm here, is
by saying gm 730.  Once ya get the ecms learned it rather easy
since there are less than half a dozen that can be used for most
any application.

747 TBI v-6-8
730 MAP (some MAF) v-6-8 TPI (some DIS)
165 MAF/MAP 4-6-8  (4cyl TBI, others TPI)
148 MAF buick turbo 6+some NA TPI DIS
749 Syclone MAP (some 4 cyl applications)
6870 MAF 6-8
808 Aussie version of 165 used MAP TPI 4-6-8
And then there are some mix and matchs of others.
