vw 1.8t ISC (Idle Speed Control

Postby yotamhks on Fri Feb 12, 2010 8:18 am

anyone knows how to activate Idle Speed Control in VW Golf Mk4 1.8t AGU?
this throttle body has 8 wires conected into it, 2 wires are dedicated into idle control in this engine.
i checked with autodata, the negative wire of this actuator gets a clear signal that is clearly used by VW
to control idle speed of this engine.
but i am in no clue to how setting this up in MOTEC.

anyone succeeded with stabilising idle in this engine using this actuator?

It is not DBW.
I used a Bosch 3 wire idle valve on this engine last time.

i know it isn't DBW ;)
but in this throttle body there is and actuator that opens this throttle about 5% when it's triggered,
and i wonder if there is a methood to control the movment to a certain point by duty cycle.
i am sure there is a way since vw use that and that only on this engine to make this engine idle!
