My actual IAC count is 0 when the car idles and my desired IAC count is 136-138. What dose this mean?

I have a 90mm FAST set up and I've been told by a few that I may have to drill a hole in the blade and back the stop screw all the way out to get the IAC counts to around 35 but the thing that confuses me is when the actual IAC count is "0" doesn't that mean it's already getting to much bypassed air and 0 is the 100% closed IAC position? If that is the case how would drilling a hole in the blade and allowing more bypassed air threw going to help?

 

As mentioned in your other thread, I'm not convinced your IAC motor is even working at this point.

 

see what your tps voltage is. if you have another thread going give us some more info on this. your deisred shoudl match so viper is prob right, its not working or not working right.

 

Ok you guys got me thinkins so I went and did a quick test by putting my IAC in my friends 99 ls1 and it worked fine in his car so it's not an IAC problem it's either the tb is letting to much air by or one of the flow rate tables is off in my edit file.

 

So swap his IAC motor onto yours; what if the connector on your car is bad? Worth a shot.

 

the iac count will be the desired, the car will not make changes to the settings to change the airflow. you have to do that manually in the tune. unplug your iac when the car is running and see what happens
