Yes, not concerned about mixture, just interested in how open, as a percentage of completely open, the OEM ECU holds the idle control motor during cold cranking. Currently have it set to 50%, with a post start up rpm target of 1200rpm at 0C sliding linearly to 850rpm at 80C.

It sounds like you're asking about the desired mixture but the IAC only controls the air ... and thus the idle rpm. So it should be set to whatever you need to achieve ~1200 rpm when the mixture is burning well. ----- Original Message ----- From: "Steve Willington" <[email protected]> To: <[email protected]> Sent: Thursday, July 23, 2009 7:44 AM Subject: IAC choke setting for cold start. Does anyone know the stock IAC choke setting (for '99 VICs, but not essential) for cold start? As a percentage of the full IAC 'door' swing would be good.
