Idle Steps
Posted: Sun Oct 11, 2009 6:29 am
MSII v.2.89 - GM IAC, SBC 383 with HSR
so i have problem with idle at fully warmed up engine with "Idle Steps" setting were like this: -40* - 160* = 40 - 160 steps.
with this setting my idle was at between 550-750 RPM. Now just to test I set @160* - 100 steps and RPM grew up to about 800-900 and vacuume went beetter.
And so on the less the steps the RPM grow. Now just by cuiorisyty i oppened stock ECM settings for IAC and found that it works like this, -40* - 160* settings are 145 septs down to 45 steps? Now i am confused which one is proper one and why my car acts better with less steps and with 160 steps has problems with idling and dies.
