Hi Guys,

I have an edge and an S&B intake. The edge was on first and then I installed the intake. The noise the intake made at 1300 - 1500 rpm under any throttle and it is most obvious when it shifts into second gear, is such that the whole truck vibrates and my foot actually tickles and it sounds awful. Now I thought it was the intake so have been tinkering with that for the last few days.

I had a buddy in it last night and he said it almost sounds like the engine noise and wonders if the engine's timing is too aggressive at that point so I may be stuck with it. I had a revelation that the programmer was on level 2, so I went outside turned it back to stock and VOILA the noise is gone. Threw the programmer on level 1 and still no noise. Back to level 2 and the noise is there. Havent tried 3 yet as still have 80 liters of 87 octane to get through.

Now I was planning on getting my edge gryphoned next extended service the truck goes in for (has warranty and a few other things so it seemes like the right time to have the unit out anyways) but am worried that the noise will remain and spending the money to get the engine tuned is useless.

Now my question is two fold:

1.) I am going to call edge today and ask but does anyone know that if retarding the spark a degree or two if this will help the problem?

2.) Will the gryphon suffer from the same issue as the edge does?

 

What level are your running and what octane of fuel? Yes, you can retard the timing a point or so by entering -1.0 or say -1.5 and see what happens. If you are running 87 octane on level 2, you could also put in some 89 and see what the results are. If you are running lean, normally, you hear a pinging sound. You need to keep in mind that the Edge is programmed for a stock intake. However, the 2006 does not usually run lean with an S&B. There are exceptions, though.

As far as custom tuning, this is all info you communicate to Bill at PHP and he adapts your tune accordingly. One other thing, without custom tunes, you do not get full benefit of a CAI. The air/fuel table needs to be modified for the extra air available.

 

I will try and answer your questions as best as I can.

1.) I am running 87 octane, however we are at the same elevation as Denver, Co (1300m) so 87 here is like 89 at the coast.

2.) I dont think it is lean, no codes or anything, just is the strange reverberation sound. BTW I have an 07 (shouldnt change your point though)

3.) I know the edge was programmed for a stock truck as well as the intake was meant for a stock truck, I just didnt expect this.

4.) I will try the 89 on next fill or even 91 first.

5.) I know bill will program for my truck, I guess my concern would be that this noise would still exist (maybe it is something in the design of the S&B and not having the right composition to deal with advanced spark (i.e. spark is advanced so much and the intake valve is still open when the spark fires and sends noise back up the intake at that exact point.

Thank you!

 

Level 2 is richer, that is how it gets more low end power for towing. I may have been looking at the problem backwards, given that it is level 2 and your altitude. If it were mine, I would bump the timing up +1.0 and see what happens. Sounds almost as if you are too rich.

 

good point actually

 

I'm just so used to people throwing a CAI on and wondering why they hear a ping or get the lean code, that I think of that first. You could very well have the opposite. Good luck with it, and keep us posted.

BTY, I thought I was totally satisfied with the Edge canned tunes. After 31,000 miles, I finally said why not, and got the gryphon custom tunes. Now I would hate to go back to the canned tunes. I used to run Level 3 exclusively and now I am happy with an 87 Performance tune. I have a 93 Performance, but seldom feel the need to run it.

 

hmm thanks, sounds like it is worth a shot anyways

 

so called edge, said the programmer is roughly 23 updates behind. WOW

Going to try that first

 

Updating might help.

Level 1 is a transmission only tune, so the engine is effectively at "stock". I'm not surprised the sound went away.

I'd be willing to bet you have what's called an "intake drone". Some intakes seem to be prone to this under certain conditions and Bill has said he can tune this out on the Gryphon. What you have doesn't sound to me like ping at all and I doubt you'd describe it the way you do if it were.

Retarding the spark MAY effect the sound, but it will likely also rob you of power. If you DO play with the spark, move it in 0.25 degree increments, and note the results. And, as Bluejay said, since you're using 87 octane at mile-high elevations, I'd try advancing the spark first, not retarding it - but I'd do it in increments.

thanks the more I think about it hte more I am going to try it after the update. And yes I remember the level 1 is tranny mode only. It eliminated the need to look at the tranny, it is quite clearly the programming for the gryphon.


The best way I can describe it is on the old vehicles that had rubber flexable hoses for the intake, when they used to fail the would collaps in on themselves and make a strange noise and if they closed enough they would make a flapping sound. That is what it sounds like temporarily.


I also dont like the idea of retarding the spark cause then the whole reason I bought the thing is to change the tables for a meaner but stronger engine. If I retard the spark I might as well run it on level 1.


Thanks guys

 

i have an 05 with a volant intake i have the same problem hopefully i get my custom tunes in today and i can let u know if that fixes the problem

 

huh so it seems like it is the way the edge changes the engine. Let me know once you get it up.

 

i think so i have the gryphon right now but with out custom tunes it is basically the edge programmer, now i have had mine for a month now that is the only negative thing about it

 

wow, just got an email from edge regarding my request.


you know Bill is good when he plugs him openly.




Also the update DID take some of the roughness out of it. Now it is just 'drone' as is described. Thanks guys, looks like the Edge is going Gryphon sooner than I had planned.
