Hey vince, i'd like to know how your stealth tunes work specifically for the 2009 cobalt ss/tc, I worked at the dealer and they looked at how many times the ecu was flashed and compared it with the times the gm Vis says its been flashed not just weather the tune matched what their files say it should be (those cheating bastards) I am just curious how one would get around that with your stealth tunes.

I know its probably been discussed, I just couldn't find the info I was looking for exactly.

 

I'm guessing you'd have a better chance of getting an answer directly from Vince if you simply contact him dirrectly. People may try to explain it for you, but obviously Vince will be eble to explain it to you best.

Unfortunately for you Vince's shop is closed from January 9th (today!) to January 30th.. Man that's shitty timing!

 

how does he know ur not just a gm tech wanting to know how it works so u can find it and void peoples warrenty. i wouldnt tell u.

 

actually I don't work for them anymore, they let me go when the shop slowed down and I have no intention of returning to the shop. I have argued about warranty **** with that shop on my own cobalt even when I worked there. I just don't feel like tuning my car and then having the stealership steal my warranty because they see something fishy.

 

holly **** tomj77 you nailed it dead on the head with that guess! lol.. either that or you know him... now how about you guess me up some powerball numbers for tonights drawing!

 

ok, so maybe my first post asked for a bit to much info lol, I don't car how it works so much, as weather or not he has taken this into account with the stealth tune. That info is much more valuable to me. How it works would be interesting, but I just want to make sure I have done my homework, so I don't get screwed like I did with my trans when it blew up at 3400 miles...

And tomj, you are right he should probably be careful with that kind of info.

 

its a trade secret. it works I can vouch for that. The flash theory doesn't make sense considering they reflash the ECU's sometimes to try to rule out data corruption. I brought my car in one time after I had the Superchips on it and forgot to flash it back to stock, and it was stock when I got it back..... I Also saw ECU flash was on the work order. (This was after my 2nd blown map sensor.)

 

well i've not had good luck with the dealer i worked for, they know my car to well, i guess i could go to another dealer we have two about the same distance from my house.

 

I am most likely going to be purchasing a Trifecta tune in the near future so I have done alot of research on Trifecta. And if I recalll correctly Vince actually had a GM Tech go through GM's procedure of looking for a tune on his tuned HHR SS and they didn't find anything. But as for how it works exactly I think only Vince knows that.

 

Well before I consider his tune or the stealth tune you can tune for with the hp tuners i would want him to personally state what was said above.

 

The stealth tune is his tune. You cannot replicate it with HP tuners, his tune is a different operating system as well.

 

And if he doesn't tell you,I'm sure your 350 dollars will be missed.

 

Vince isn't going to share this info on "how it works" with anyone... not any other vendors(to keep them from competing): DEFINITELY not ex or current GM techs

so, uhh, good luck, lol

 

just get the tune, its WELL worth it

 

i wanna become a dealer, mainly so i dont have to go to someone else to tune when i need to, how do u become one and how much does the stuff cost?

 

Get the ez flash cable and add yourself to trifectas' dealer list.

 

where from?

The tune is 100% undetectable via CURRENT dealership service departmentprocedures. This has been verified. I can't guarantee the dealers won'tchange their procedures and I can't guarantee the dealer won't send the ECMback to an engineering team at GM if there was a drastic warranty claim,though. - Vince GegliaTrifecta Performance, Inc.Duvall (Seattle), WAPh: 206.595.3061http://www.trifectaperformance.com Shop/Phone hours: Monday - Friday, 9AM - 5PM, PST(we monitor email outside shop/phone hours) Want PCM programming without the hassle of removing and shipping your PCM? http://www.trifectaperformance.com/pcm


i sent vince a message asking if it was undetecable and this is a copy of what he sent me

 

People have found a way to have Vince tune things HPT can't and then tune on top of that with HPT.

AND, you can get stealth with HPT as well. Just had my car serviced and they checked the VCM and found nothing..

 

Yep, a write entire with the stock file will write over the calibrations that were done.

 

Well Vince has dug very deep into our ECM.

He is using the extra available space on the ECM to do some pretty cool things.

It's my understanding that GM has a reference number when they view a Cobalt. That reference number should match for a stock file or a GM stage file.

So Vince re-writes his tune to mimmick the correct GM tune reference number.

Therefore they plug it in at the dealership and they see that it matches a GM tune number and they move on.

Now if they went on a drive and noticed the massive power and increased redline they would fine it to be an aftermarket tune.

So someone please correct me.

 

yeah but they would have to drive it, and activate the tune by pressing the TC button twice or cc buttons, which they would have no reason to do.

 

Yah but you need the HP Tuner or someone who has it to flash you back to stock. Which IMO isn't as good as having a tune that is undetectable in the first place.


I'm pretty sure if you have Vince set up your tune with the Cruise Control button then its:

Cruise Control OFF = Tuned Mode
Cruise Control ON = Stock Mode

So if they drove it they would be driving it in tuned mode.




I think I'm going to be getting the tune + cable in the near future so that if something does go wrong and I need waranty work (knock on wood) I can be extra safe by flashing back to stock even though the tune is un-detectable.

 

None the less, it can be achieved with either is the point.
