Alright, I have been playing around with this I got the Idle Airflow values to match my MAF gm/sec. LT Fuel trims are -6 Bank 1 and -2 Bank 2. And desired airflow is like 6.7 gm/sec and MAF airflow is 12.5 gm/sec. You have to move the IAC effective area table over about 12 spots to get these values to match up at 12.5/12.5 gm/sec and IAC trims are 0. And the car seems to run worse with them matched up as if you don't touch them. Looks like what changes the most is with all that changing the IAC position at start 192 when real cold but on warm starts it is like 72 and it has a real bad cruise control effect. I am trying to figure out what I am misunderstang to getting everything lined up correctly. And what is the proper way to get correct gm/sec values for the IAC Park position vs. IAT I have moved them up and down and it doesn't seem to make a difference where you have them so I have left them at 21 gm/sec? Thanks.
