What
is an "idle up" valve?
Looking over a CIS-E system (O2 box, no knock sensor box that =
the
GTI/GLI/16V has) there is nothing attached to a AC module to control the =
idle
like there is in the Digifant and Motronic systems. You are also =
right, a
idle stabilizer valve is a function of CIS-E. There is the idle
stabilizer which is controlled by the O2 computer and the idle =
stabilizer relay
that gets a pulsed signal from the tachometer signal. If you turn =
the AC
on or any other load it will simply allow more air to by-pass the valve =
and the
idle will remain the same. I have omitted the idle stabilizer =
valve for
customers who can't afford the big price tag for a new one. I =
replaced it
with the warm up valve from the CIS system and adjusted the idle for a =
nice
900RPM.
From
the sounds of things I really don't think you have a CIS-E system. =
I think
you have a CIS-Lambda system. There are a few quick ways to tell =
by
looking at your fuel distributor. What color is it black or shiny =
silver -
if it is silver it is CIS-E, also is there one or two electrical =
connections to
it? If there is two it is CIS-E.
If
there is an idle stabilizer - don't worry about it. If it is doing =
it's
job the idle will remain the same when the AC is on.
If you
have a CIS-Lambda system. I have some diagrams here that will help =
you set
it up.

OK, here's one for the record books. I'm getting =

on the =
installation
of my 1.8L inline VW engine, in to my SS Syncro. I have one item left
to
figure out where it gets wired =
in. The
Idle up solenoid valves. There were two in the VW
Fox system, one been used obviously for the AC . =
The problem
is I need to establish what controlled the
second valve. Now this is interesting. I =
can't seem to
find a wiring diagram that shows the CIS-E system running this =
valve.
The Wiring diagrams I have showing the CIS-E Systems all have a =
idle
stabilizer valve.
This valve (the =
idle up
solenoid valve) came with the Fox motor. It is the same solenoid =
valve
that is used on the CIS system with a O2 =
sensor. A
simple valve. I have the wiring diagrams for several Golf , Jetta, Fox =
CIS-E
fuel injection systems. They all show a idle stabilizer. Anyone have
any
info. on its wiring? I must =
be missing
something here? Any info. would be appreciated
