Idle & IAC help for a newbie tuner...

[Jimmyz]

I'm brand new to this "tuning on my own concept". I've paid others $1000's for tuning that just isn't cutting it. The tune AFA performance is pretty good. I don't know if I can get an idea of air/fuel ratio with HPT but I'm sure it's somewhere.

I have a surge/hunting condition w/my 383 LS6 set up. The car has a high kPa at idle and low engine loads (55+ kPa). I think the car needs more air. Is there anywhere y'all can tell me to start?

I know NOTHING about this new tool other than how to scan.

Thanks

Jim

Scan your LTIT's and STIT's and see where they are at. I have a spreadsheet somewhere on here that will plot out a new Running Airflow Table that might help your problem. Also take a look at your IAC counts. Normally you want them to be around the 30-50 range. I just did a car this weekend and he had some bad surging/stalling and the IAC was over 120, lowered it and all is well again.

I can't figure out where to change the IAC counts? :-[
