Well, wait Scott... There are 2 Motronic systems used by VW... one is 
K-Motronic and one is L-Motronic.  The 16V cars were first CIS-E, or 
K-Jetronic.  K-Motronic (on the 2.0s) integrated the system into one 
computer, and it could therefore also control timing... and it was based on 
CIS-E.

The later Motronic cars (ABA, VR6, etc), use L-Motronic, which is "full 
efi".  The difference is that the K stands for Konstant in German, meaning 
of course constant -- or continuous... i.e. CIS.  The L systems use pulsed 
injectors which open and close to deliver more or less fuel.

So, the ABA uses L-Motronic; the 9A uses K-Motronic.

Digifant was VW's attempt at an FI system; and seeing that they switched 
back to Bosch systems, it's clear that they agree with everyone else -- it 
sucked.

PS: I'm too lazy to run downstairs for my Bosch FI Book -- but if anyone 
has any questions lemme know and I'll get up. :)
