IAC Inflection point?
Has anyone ever experienced an inflection point in their IAC valve? That is, when using the idle valve test, in the lower % (say around 10) idle seems low, stays approximately in the 950 range until I get to 30%, then it lowers even more, in the 850 range, then as I increase the % the rpms increas as well.
Anyone ever experienced this? The reason I ask is because when in CL Idle mode, if the steps drop all the way down, my rpms are still high (1200ish) and the controller thinks it has no where to go since the steps are already low (20 steps, 7.8%).
The stock computer handles everything fine, which leads me to believe I have a setting wrong in my .msq. I attached my msq for reference.
The rpms at 20 steps still seem higher than the should be, which is probably what I am really trying to figure out.
Please let me know if you have any ideas. Thanks!

That is exactly what I noticed. Phew. How do I prevent the MS from going so low? I set my Idle Valve Closed Duty to 30, and Open Duty to 65, but the MS will still allow the % duty and steps to go below the 30.
