Nothing?
Searched yet??
I'm sure the question has been asked before, wouldnt hurt to try and find a thread with the same problems as you while you wait for a reponse.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
I have searched and yes i did find some threads on the idle topic but just cant see to comprehend itOriginally Posted by 5FDP
You need to read up on tuning, using a wideband if you have it, narrow bands if not. Your cam will have have your ve table out of wack. Here are some basic tweaks that should have it idling a little better, but you have some reading to do.
Thanks will upload the file onto the PCM tomorrow to test it out, can you explain to me what you did?
Increased idle speed, increased idle airflow, leveled out timing in idle areas so that it would effective with over/underspeed settings, and put your iat timing retard back in. Use the compare feature with file you posted and the one I posted.
Find the Russ K idle config and instructions, you will need it.
There is an idle tuning guide by rinkrat that is decent, or will get you going anyway.
Will update tomorrow, thanks again
Don't load that file onto your car, just do what he said in the previous post and compare them and copy over some numbers.

Managed to get the idle just about right, but now my Air fuel mixture is out of wack, will be logging tomorrow morning. Im new to this so i still dont know how to richen it or lean it out
Simple mistake, didnt see the name of the "file" given at the start, just assumed at the time that you had given him one of your own files for him to compare. Didn't realize you had the ability to open and change his tune for him.
