AS far as I know the D-Jetronic is an analog MAP system built on transistors. Got one my self. It's primarly designed for 4- & 6- cylinders, but is also used on V12's with a booster amplifier for the injetors. It works in batch mode, so it fires a group three injectors three times (?) each cycle.

Those two part num's that you got could be different sets for e.g. a 4-cyl & a 6-cyl engine, but I'm not sure. I sugest that you take a peak inside the box and for instance check how many transistors are mounted on the cooler. This might give a lead (the V12 type has no cooler).

Good Luck :-)
