looking at a 997-2 system, and how everything is run, I am suprised at how simple it actually is. other manufacturers direct injection systems are much more complicated, with either a mechanical pump setup or high voltage injectors, with a separate driver module, etc.. Porsche seems to have simplified gasoline direct injection quite a bit, compared to others. this setup doesn't seem much different from a normal fuel injection, since the injectors run at 12v fired directly from dme.
