I have not heard back from Justin on exactly "what" would have changed the noise, and to be honest, he never knew the noise existed. I was dealing with it by myself while he was doing his thing just basically doing a final tune.

I'm no expert, but I am sure the idle speed, idle timing , injector timing or whatever was setup biased to a random setting by Justin just to get me going with a cam, until he could see a real EfiLive data after the cam install.

Whatever settings he finally applied did the following:

1) Lowered my idle speed, to what I feel is perfect. (Prior to that, it was very fast 700/725 in P/N, 645 D, and it "hunted"). It is now a stable 625.

2) Removed the valvetrain noise SIGNIFICANTLY.

3) Gave the truck more "cam" lope sound. Previous "helper" tune had a real fast idle with ZERO cam lope/stutter sound.

Now realize, my problem was mostly ticking/sewing machine and a loud "Tap" at idle, with valvetrain noise (sewing machine) thru the RPM ranges.

This is gone.

Honestly I don't care what he did, I just thank god it is gone.

The truck also runs like a scalded ape with his tune job.

Just thought this info would help anyone that is going crazy with valvetrain noise

 

Well, we care. The idea that you think that telling us that the noise is in the tune is no help at all if we don't know where to look. I'm sure that you are honestly trying to be helpful, and maybe you don't know that what you are saying is no different than saying "The needle? It's right there in that haystack!"

 

The reason for my interest was because I recently have been wondering if all the additional timing that is in my tune to improve the light throttle drive-ability might have some effect on the valvetrain noise.
I mean, what if the cylinder pressure at light throttle is higher than it is supposed to be, and that puts that much more load on the exhaust valve components, and it is very noticable at cruise speeds?
Just one of those wild thoughts that I usually try to keep to myself, but original post made me share it.

 

Okay, if I get some answers from BlackBear, I will post what the tuner says would have cured the noise.

But understand, I came here immediately to help others that may have this issue, as there are hundreds of posts on the internet on LS type sites that lead to absolutely nothing, a lot of people talking pushrod length, preload, header noise, blah blah blah, with no final results of quiet valvetrain. So I was posting to help save some greif for others.

Realize, noise was there with a false or quicky tuned ECM. Removed said ECM, installed an exactly tuned ECM, noise instantly goes away.

Is that not solid enough data from myself who owns the truck nearly 2000 miles away from the actual ECM tuner?

 

This is starting to sound like an ad for BlackBear. If he knows what quieted your valvetrain, he's not going to tell you. If he doesn't know, he might share some information like "yeah, your blah blahs were pretty weird and I put them back to stock, maybe that did it".

 

I dont give a flying' fawk what you think. I am trying to help people, so what if I happened to use BlackBear. Could have been Nelson, Wait4Me, whoever.

I just realized that in my efforts to help people, I got so lucky enough to run across a live free-range internet douchebag.

Screw this forum.

 

I thought I was being reasonable and trying to get info on what in a tune could possibly help, while also expressing my cynicism. I told you that I found it interesting that I had similar thoughts and your post showed up. My whole point is that your saying it is in the tune isn't any help. You do seem easily upset, I think you might have come undone even if somebody who isn't a douchebag like me was making my point more politely than I can.

 

 

I can see his point about trying to look out for everyone...but it's not like its always going to be in the tune and if your not doing your own tuning who knows what he changed, what he didnt.....it could of been a fueling issue, it could of been a timing issue.....it could have been a million different things. 9 times out of 10 any "noise" coming from vavletrain isnt going to be a tuning issue I dont think...of course unless the tune is severly whacked!
Cant we all play nice?

 

We need a smilie for sticking yout foot in your mouth. We'll call it the MikeGyver smilie. And for everyones information, I'm not an internet douchebag, I'm a real life douchebag. I would say everything to your face that I say here, I don't understand why people are so sensitive to what they read, compared to two buddies having the same conversation face-to-face.
