I may try that i was wanting to tinker with the dyn air settings anyways, Thanks.

Being my own truck i dont have much time to work on it but it has been a test mule for anything experimental or educational. Thing puts down 350 on a mustang dyno which is the na 6.0 record in my shop.
Not fixed. Started surging backing out of a driveway and stalled. Im thinking i have a mechanical or electrical issue. It was also hard to start back up. Cam sensor issue?
Just needs to be properly tuned.

I've never seen so many settings changed in the Idle Airflow Tab in my 20+ years of doing this.
I have tried setting everything back to stock under the idle tab and starting over more than once. I have never made so many changes on another vehicle. Something is wrong with the truck and i cannot pinpoint it.
You keep saying that. The tune is jacked.Originally Posted by 04silverado6.0
Meanwhile, you ignore all advice given to you, you don't post any new data logs or tunes file but yet you come back and give a verbal description of what it's doing.

I bet fuel is swinging around with ambient conditions, hence IAT. Goes back to the complex temp model. SD worked well one day and then not the other. VE is the key. Correct idle follows. O2 and complex temp settings, etc to default precede.
Hard to tell without a log of course.
And this guy is supposed to be a "pro".
A bunch of stuff needs put back to stock and start over.
Half the file is jacked up crap that doesn't need to be changed and the other half ain't right.

Id like specifics on "jacked up" and "aint right". Biasing more toward ect brought the cold start and hot start wb error closer together. Still have some lean on cold and rich on hot so probably could go a little further. I did hook the laptop up and data log after and could not reproduce the issues so no data log today.

For sure weather or temp related. My braf seems to change greatly under different conditions.
You're the pro. You should know.
You've gotten to the point of pointless to even reply to your posts.

I dont know what suggestions i havent tried at this point. Everything suggested i have tried in the last 3 years. The ve and maf have been gone over repeatedly with different modifications. Not counting this was at 2 different shops before i bought hpt. All the hacking or whatever was things that changed this for the better. I have copied all stock lm7 and lq9 idle adapt tables, throttle follower tables and reworked them. When the basic tables that need changed dont do the job why not try other options?
Since your a "efi specialist" send me a file to try and i guarantee it will be worse.

Do i need to keep going?
Seriously, you are attacking the wrong tuner. edcmat goes back every bit as long as I've been in the business and has tuned more vehicles not only in this country but all over the world. You've been at it what, 3 years maybe? If you've never had an unhappy customer as a tuner then you've not done much tuning.

I do not appreciate the asshole remarks from Ed. Just trying to figure this thing out and hopefully learn something. Seems thats in his character. Either way there is not much i havent tried in the tune at some point and im just not getting anywhere. I have been in hundreds of gen 3 pcms and the only times ive had this issue it was resolved by ve tuning which doesnt seem to be working here. Cannot say ive had an unhappy customer or something i couldnt make right.
So your answer is to get on a forum and link a few negative reviews about him because you don't like his replies in your thread. OK.
Guy can pick apart my work but cannot tell me what is wrong with it? Just a douche. Probably butthurt because he dont know himself.
This reminds me of a problem a guy was having on here. We tried this and that with throttle cracker/follower. Turned out his aftermarket converter was dragging rpm's down. Happened intermittently. If you look at the log from Post #51 time 5:50 you can see the possibility of the same thing going on. In his case a part helped, but forget what it was. But here, the tune says it should be unlocked. Why is min duty cycle so high, and why is 3rd apply/release disabled?
Log TCC slip. That's how I confirmed the theory and solved the problem.
Yeah. 8:01 it's happening. TCC is locked, it's in 2nd gear at idle transition, and rpm's are dipping to 650.
