Zmanco Posted July 11, 2008 Share Posted July 11, 2008 MSII Extra is supposed to have a feature shown in this screen capture where you can set the cranking PW for the IAC and then set how many seconds will be used to taper it down to the normal idle setting. But for me, it doesn't matter what value I enter in that field: within about 1 second after the engine starts, the idle just drops. It turns out that on a cold start, this isn't an issue, but for a warm start, the engine stumbles for a second or two until the PID takes over. Is anyone successfully using this feature?
