2L 16v engine work ok with (base) CIS?

[raveracer77 at yahoo.ca (Rave Racer 77)]

    Just fixed my internet temporarily so I haven't been lurking for a few 
days.  Just rebuilt my GLI and still have some bugs to work out.  The PL 
head on the 9A block is nice but not what I was expecting.  I still haven't 
put the knock sensors back on because they were totally rotted so I have to 
pull the ones off of two of my parts cars.  The 8V's only have one sensor so 
I'm going to have to pull them from two cars.  I'll then dip them and the 
old ones from the 9A in that tool rubberizer stuff and put the two best ones 
on my GLI and the crappy ones on my 8V's.  As for right now I'm running 
without them.  From what I understand they're only used to retard the timing 
to keep it in the right territory and aren't that intrusive otherwise.  I 
might be wrong about that but I'm not really an engine electrics guru.  Did 
you say your block is a 9A or ABA?  The PL head is rumored to flow better 
unmodified then an unmodified 9A head.  As for the CIS, I don't actually 
know as I haven't worked on 8V CIS much.  I might have a spare around here 
as I've parted out a couple of cars and I'll take a look to see what's 
different but I've been messing around with this stupid Fox and I think I've 
tried swapping in all the different modules in there so they're probably all 
useless at this point.  I'd be curious to know what happens in your 
situation but I figure that most logically the newer engine would have more 
sensors on it but the old computer wouldn't need them all.  Basically as 
long as the block fits in the car the computer should find all the sensors 
it's set up to use and the block shouldn't care either way as long as the 
computer is happy.  That's a guess.
