digifant (there is a T at the end)  and digijet are both bosch fuel injection
systems that vw used. digijet was used 85 down, and digifant was used 86 up.
presumably the digifant gets better fuel economy, but its not much. the
digifant seems to be more tempermental and the ECU's can be problematic, but i
wouldnt bother swapping your entire fuel injection system over..  that would be a
huge job, not worth the gain.
