looks like it maybe electronic but not computercontrolled.. as we think of it today
"Analog fuel injection. The 'D' is an abbreviation from German: "Druck", which means pressure. The depression (vacuum) is measured using a pressure sensor located in the intake manifold, in order to calculate the duration of the fuel injection pulses. Originally, this system was just called Jetronic, but the name D-Jetronic was later created as a retronym to distinguish it from the newer versions."
