I won't be able to get back to tinkering with my car until Monday after work so I thought I'd post these questions here in lieu of some trial and error experimenting. I have my car idling pretty good at 700rpm when warmed up (starts right up cold (~45*F) as well), and have the IAC set with the warm up(with the MS2 2.89). The throttle body is 1,000cfm and I have the throttle plates pretty much closed up and it's idling through the air bypass and whistling pretty good, like sucking through a straw :P. Now I figure I can open up the throttle blades a bit with the idle adjustment screw and pull some of the air out of the IAC, does anyone know for sure if this will quiet it up? Checking one of the data logs shows it idles at 650rpm (I've bumped it up since then) and a MAP reading of 40kpa.
Now when I adjust the idle screw should I re-calibrate the TPS sensor? Is there an option on MS2 v2.89 to have it target an rpm with the IAC so when I go from 7000' down to sea level my idle stays the same?
Thanks.
