You are confusing the Digifant system vs the Digifant II system that is
found in the Golfs and Jettas - my mistake - sorry!

This is part of the reason (the 15 degree thing) and the other reason is
for some people, the less electronics means the less things that can go
wrong. I take my Syncro 4 to 5 hours into *no where* i.e. if it breaks
down, I'm walking - for days - before I see anyone! In my parts box there
is a spare fuel pump, alternator, motor cycle battery and a points
distributor - with these parts and CIS fuel injection I can get home if
need be! With CIS-E, Digifant-II or Motronic yer stuck if something vital
to the fuel injection system dies. For those of you with AAA and never
stray from populated areas this isn't so critical - for some people it is a
problem. I have a couple of customers who are planning on going to South
Americia - they want simple and bullet proof stuff under the engine cover -
I don't blame them!
