<x-charset windows-1252>All cis-e cars had a knock sensor. Even the saab's and porsche's that used
it. Yes your compression should be about 10:5:1. The knock sensor is a
little microphone covered in plastic that detects pinging, and tells the
KE-Jetronic box to retard the timing slightly until the pinging goes away.

1) I've heard that the compression ratio w/my original 16V head will be
anywhere
from 9.5 to 10.5:1.  Can anyone be more exact on this?  Dan Brideau?

2) I don't think the 1988 CIS-E had a knock sensor, right?  Will I need one?
Can this be integrated into CIS-E or must the system be swaped-out for a
later
one?

3) How does a knock sensor work?  Is it some kind of acoustic device?

Bill
