Ok guys, I have been searching and reading threads on lowering your IAC count when tuning the Idle. But yet I have come across one that explains how you accomplish this. Well I have come across one but it just tells you to raise the 40C mark up to 21. Here is the link:

What are you guys doing in order to lower the IAC count. The truck Idles ok but I think it can do much better. My IAC counts are around 180 and people are talking about getting them down to 40-60. Someone post me in the right direction please.

Oh and is the RAF also known as the Base Running Airflow?

 

easiest way is to chop off the first five cells with data and shift the entire graph to the left.

Edit: In the IAC steps vs effective area table

 

So I would go under IAC park position Airflow, clear the data for the first five cells (that means -40 to 104F). And copy the next five cells (140 to 284) and past them in the -40 to 104 position. But then... what values would I use in the last five cells since I shifted them over. Thanks.

 

Cmon where are the tuning brains at
