trifecta tune and issues
OK so I bought a 2007 cobalt ss /sc 2 weeks ago. Worked great , lots or power never an issue.
This week installed zzp stage 3 kit with 2.8inch pulley and had it trifecta tuned. NOW I am having a small issue with bogging from time to time on take off and have asked Vince at Trifecta to help me with the issue.
THIS is his response after seeing logs :
On tip in, something is causing noise that the PCM thinks is knock so it
pulls a bunch of timing back out, causing the bog. There's no tuning
related issues, though, so I suspect mechanical noise or something else.
This is very common with solid mounts.
- Vince Geglia
The car was perfect before the tune , this only came to be after putting the tune on and driving the car. I don't have any more power now with the trifecta tune and stage 3 kit than i did from the car lot factory. The mounts on the car are all factory mounts....anyone have some experience with this or is it the tune....thoughts appreciated

I have a header and high flow cat along with the stage 3 kit with stage 3 heat exchanger. My iat's are 127 degrees....
I have Vince from trifecta already remote tuning me and he says I have a phantom knock throwing my timing off and I need to find the source....so i am wondering where to start ? I retorqued my header bolts , regapped my plugs , do i really need to replace all my mounts on the engine ?

Thats a common place for the LSJ's to knock but it can be tuned out and adjusted for.
Look into borrowing or buying a HP Tuners, if you plan to keep modding the car it isn't a bad investment to make honestly!

Well I spent 400.00 on trifecta tune and the programmer , if it wasnt for that I would agree with you about HP tuners. I just emailed vince and asked him to tune out that knock sensor and adjust around it and I am awaiting his reply. If he doesnt do it , I will try for my money back and go with hptuners.

Its not false knock, I honestly don't agree with that..
You can easily resell that cable and you will have to eat the tune fee unfortunately. Find someone with a HPT and Ill help you out

I mean im not bashing but Having KR on a lsj is easy but with just the pulley size you have and ect i dont see a kr issueunless the tune is off. Now if there is somthing loose and causing kr then yes i can see a bog. But to me id check your ic pump because if the iat2s get to high then the car will pull timing and it will bog... Also with the lsj there is a ton of timing maps to work with. And if they are not taken out of the tune they have the ability to take timing. If ther is a way to view a datalog please do. Cuz i myself say either its the ic pump/ Or the sc coolant flow like laminovas and ect or its the tune.....
One other thing if its raining out, or humid the lsjs like to stumble because of the maf getting some type of moisture on it so look at this as well!!

Its not weather related, and he says my iat' temps are around 127 degrees while driving so its not my ic pump bogging me down .... he says its some false knock from something on the car pulling timing and making it bog , but i think there is NO issue at all with my car and he isnt taking the time to do his tunes....$$$$$$$$$$$$$$$$$$$$$$$

What can I ask Vince to do with my tune to get rid of the issue ?
Again , this was his statement :

I see the problem.
On tip in, something is causing noise that the PCM thinks is knock so it
pulls a bunch of timing back out, causing the bog. There's no tuning
related issues, though, so I suspect mechanical noise or something else.
This is very common with solid mounts.
Your IAT2s are around 127*F now, which are decent.
I can't do anything about false knock.

and than....
Oh, no matter what I'll do whatever it takes to help you solve it. I was
just saying that the issues that are causing the bogging aren't anything
that need to be (or can be) fixed in the tune. Sorry if I came off the
wrong way.

That cannot be true , my car was fine before the stage 3 kit and tune!

BYT is a competing vendor he can't tell Vince how to tune your car. If I wasn't within driving distance from BYT I'd purchase hp tuners and have him send me tunes through email. If Vince doesn't want to provide you with the best customer service then go with BYT and be blown away at how nice he is and spot on his tunes are.

Ok now if say you go from a wot pull and just stop you will get heat soak. the heat soak is one big bad KR maker on the low end if you say were to tap the throttle.. I mean its not gonna be like you tap it and the kr is crazy its more or less after wot pulls cruise a little forsaftey. If your bogs down alot all the time everywhere and ect id say check every thing before saying (its the tune) Look at your maf sensor, fuel pressure, air filter, t.b, and spark plugs. If you use copper core plugs id say go with iridiums because most of the time its got a finer eaiser burn and its good with heat. So you need to look at everthing and let us know what you find!!

It most certainly is tuning related IMHO. Those cars take some work to get that knock to go away when pulling away from a stop or blipping the throttle, its common and something I usually work on the whole time we are logging to clear up. There are def things to do to cure it and it should NOT be there.. I disagree with it being something loose in the engine bay. Your best bet is to sell your cable and look for a used HPT.

Lmao. Bwfore u do this op please look dor another issue that can be related to this...... What i am telling you is true. I mean it can be related to the tune but you cant just say oh yep its the tune when theres contributing factors.... What happens whwn u have a dirty maf or air filter or ect. (itll skew readings so therefore be incorrect ive been tuning these.lsj since shot hptuners came out with the software for them so i know what to look for before saying its the tune.. So please look at my point op then go buy ureself hptuners and pick ureself a tuner.
