I'm guessing that this is the airflow the IAC shoots for when you initially take your foot off the throttle. Is this correct? And if so, could we help solve post throttle closure stalling by raising the values a little?

Also, are the temps in that table for the intake air temperature?

Yup.

Raising the target IAC is the "other" way of taking care of your idle on a cammed car. It also doesn't require drilling the TB.

The temperature in the x column is the engine coolant temperature.

To reduce the IAC count, increase the table. To increase the IAC count, reduce the table. As with every thing else in LS1 edit, it is backwards.

Good Luck,

You sure about that Kevin? What we're entering in here is the target airflow for the park position, right. Without drilling a hole in the TB or cracking the TB open a little more, the IAC pintel position for a given idle speed should be the same since it takes X amount of air to maintain said idle speed.

And are you sure it's backwards? Let's say at 80 degrees C we set it to shoot for 15 gms/sec rather than 10. For 15 gms/sec to pass through the IAC it would obviously have to be open more. Open more means a higher pintel position. Am I missing something?

So, I would expect that raising these values would mean that upon taking our foot off the gas, the pintel would return to a higher position initially but then at idle would settle into whatever position it needs for wherever the idle speed is set.

Thoughts?

Nope your right, I'm smoking crack. <img border="0" title="" alt="[Embarrassed]" src="gr_emb.gif" />

I just looked at what I typed, it is incorrect.

When you use the tables, admitting more air raises the IAC..... like it should.

I got mixed up with the old fashion way where admitting more air lowers the IAC.

Wow, that's the second mistake that I have ever made <img border="0" alt="[bullshit]" title="" src="graemlins/gr_bs.gif" />

Thanks for catching it. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

LOL! Well, that's what I'm here for. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Thanks for the help though. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
