I agree with you regarding digifant.  Watch your terminology, though.
Digijet was used on the older vans, was introduced as an upgrade to AFC.
The important thing to distinquish is that AFC, digijet, and digifant are
all pulsed systems, meaning the injectors are electric soleniods which turn
on and off, while CIS, CIS-E and CIS motronic are all continous systems.
CIS systems are not pulsed and spray fuel continously.  Digijet is NOT
CIS-E, not even close.
