Do you mean Idle Airflow or IAC Effective Area?

This is what I am looking for.

"THROTTLE BODY
If you have a bigger throttle body (FAST 90, or Nick Williams) you want to multiply your Effective Airflow Area by 48%. (put in 1.48, select the whole row, hit 'multiply')"

Thanks,

B4403. Did you get the Fast 90/90? Multiplying never worked for me. Most people say to move it down (or right if you use HPTuners) 6 places. I ended up having to move mine 9. LMK if you need help or don't understand what I'm talking about. Afterall, I am a crazy loon.

Whats B4403? I looked in Tuners and could not find it. Is it in Idle RPM? I got a ported stock TB. The idle shoots way up upon start up, and stays there for about 10 seconds or so. Yeah, your help would be greatly appricated!

It's the IAC Effective Area table. It should be in your idle section somewhere. I've never used HPTuners before. B4403 is the table number. Can you do a search for it in HPTuners?

B4403 is for EFILive and HPTuners doesnt search by table identifiers.

HP Tuners-> Engine-> Idle-> Idle Airflow-> General - scroll down to "ETC Area Scalar".

Stock value is .0255. With a NW 90mmTB 0.0320 seems to work best for many of us. See this thread ->http://www.efiforum.iqd.co.nz/showth...1344#post11344

I didn't catch that he has a Vette. I just saw his username and remembered that he had an F-body before. I had forgotten that he got a Vette.
