        The two systems are quite different in their internal bits, but
are closer in their pin outs if I remember correctly. Digifant II was
never
used on the vanagons so I assume you are looking at a Golf/Jetta Bentley
(or the Probst book I suppose)...

        Digifant II performs idle stabilization and includes a knock
sensor. I also believe that Digifant II has OBD... A couple of the pin
outs are different from the Digifant I ECU if I remember correctly. I
don't believe that the digifant II was ever used on a 2.0L engine
and someone had mentioned that its maps were most likely optimized for
a 1.8L engine... Not sure what size AFM it is supposed to be used with
either...
