Well David, as usual you hit it right on the head. I want to be able to
use my Digitool on 3 or 4 different VW FI systems without having to have
a spare modified ECU for each type. The Digitool is a great invention
and I want to apply it's benefits as broadly as possible.  Having a
single "T" adapter with  DB25 pigtails wired for each ECU type would let
me do this easily.
