Hello.
I know that megatune has an menu to change the Idle speed. But what about the screw?

I start my engine and the Idle speed is 1300 rpm. I want to low it at 1050 (JRSC). I change in megatune and the car doesn´t move. still in 1300. If i move the screw i can get up the rpm, but not low.

What can i do?

Sorry for my english, is not my native idiom.

 

maybe you have a vacume leak some where

 

I have the same problem and have never been able to figure it out. I also idle at like 800 cold and then it rises to 1100-1200 when warm.

 

You may need to adjust the minimum and closed idle DC values.

 

i try that as you told me but didn´t result. i have a idle at 1400 rpm. i need help
Matt i will send you another log and the msq and try to see that. Thanks.

 

What are your minimum and closed DC set to now?
