ok so here is what happend,

I have been talking to vince and i got his tune (the switchable tune)
my set up was:

turn on the car- Stock tune
Comp. mode- aggressive tune

I took it to the dealer today to a friend of mine that its a GM certified technician, and he plug in their reader.

he could not see any modifications on the ECU that i have another tune hidden somewhere... it read as if the car has never been tuned or tricked before and he told me that warranty would still on.

So for you guys t hat had to make sure that the dealer would not find out that you have a tune, there you have it.

I have not gotten the "crazy" tune since vince still working on it...

GO GET TUNED NOW SINCE THE DEALER CAN NOT FIND OUT

 

This a breakthrough like no other!!!!!

 

yes siiirr! im so happy i can take my car to the dealer now

 

Thanks for posting with the up-date. I also mad a post after Vince called me. I wasn't sure if you would make it to the forum today or not.

Thanks again.

 

does his reader see it if u go into comp mode?

 

I am a GM certified Technition and i know exactly how to find out if there are any re-calibrations to the ecm! the calibrations and id codes will change and there are only two id and cal numbers gm has for the tc.. stock and stage 1. Also there are gm parameter ranges set in stone to expect as stock and normal for none tampered with ecms.

Gm also posted a bulletin as to exactly where and what to look for when searching for ecm alterations.
Dont get excited haha. get the wrong tech and he/she will find it. not to mention altering boost will void powertrain warrenty and that is easily spotted in parameters and on test drive.

 

Now all gM has to do is put out a TSB and say if suspected of ECU tampering verify performance in Comp mode with test drive lol. Do you honestly think GM doesn't monitor these sites? If there were a way to keep it secret then it might have a shot but not posting it all over the place.

I feel bad for the stock people that have followed GM's warranty to the letter. This is going to make it harder on for GM to figure out who's breaking the warranty and who isn't . The un-modded owners are gunna get caught in the middle.

 

Saweet!

 

soooo if they take it for a test drive and put it in comp mode ur fucked.... i'll stick with my second ecu and tune

 

Well i see it as this way, if they come back and say why that your warranty is voided for a tune in comp mode, I will be asking why in the hell they had it in comp mode. When they say they had it in comp mode i would be bitching saying why the **** they had it in comp mode and running it. Unless you bring it in for the comp mode part then you have nothing to fall back on.

 

I don't see why people try to warranty there modded car. If you can't afford to mod your car, and blow up, then you shouldn't be modding your car.

 

It will be GM's way of testing to see if you have the hidden tune.

 

interesting post...

 

Some 1 question for ya! What if someone uses a secondary ecm or pcm can the tech know if they have been changed out?

 

So are all of Trifecta tunes 2 stage like this now or not? Any ETA on the "crazy" tune?

 

mileage will be wrong.

 

dont display false information

 

how the hell do u figure thats not wrong?

 

Mileage is not stored on the ECM it is stored on the BCM. So therefore switching between ECM's will not display a different mileage.

I believe Vince knew how the Tech II worked and made it impoissible to even find the tune. It will show that it has been flashed but it will show that it has been flashed with a GM tune.

 

well i learned something today. thanks. i coulda sworn that i had heard not to switch ecu based on the mileage differance...good to know.

 

I think it's funny how there are still all the nay-sayers.

Vince has the tune setup to give the Tech 2 scanner your stock ECM calibration codes while still allowing the ECM to self diagnose itself.

So other then the Tech 2 scanner, how are you going to determine a tune?

To the OP:
When they ran the Tech 2 scanner on your car, was it in comp mode?

To the nay-sayers again:
You can choose what button setup you want for your car to switch the tunes. So even IF they read the forums, your car can be different. What are they going to do, issue bulletins telling the tech to press every button in your car and drive it after every button is pressed?

And I really hate all you that want to **** and moan about people wanting to keep their warranty intact. The tune Vince puts out is so safe that EVEN IF you are running the tune and need warrranty work, odds are very high in Trifecta's favor that it didn't cause the problem AS THEY HAVE NOT HAD ONE DOCUMENTED PROBLEM WITH THEIR TUNE HARMING AN ENGINE. So YES, having the stealth is GOOD for ALL customers as now it doesn't give Government Motors the ability to void the warranty on a part that the tune didn't break. So screw your holier then thou crap. I guarantee if something breaks on your car, you are going to try to get it fixed under warranty first, and you would be pissed that they void your warranty for a tune that has NOT cause a single problem...

 

The ECM will return the "stock" CVNs regardless of whether its in comp or normal mode when scanned.

I simply read the dealer's bulletin for checking for aftermarket flashes. Our new tune will pass this test.

 

Your some what on track, but a lot of the members of this forum their parents bought them their car. So they will try to get warranty work on stuff they knew they caused to fail. I've seen it happen. But it would be stupid to void the warranty if you had different bulbs in your car and your tail lights burned out. Dealers are no where near innocent at all, so you shouldn't cut them slack anyways. I've blown 16 map sensors now on my 09 ss with 4k mi with a k&n filter that is all. They have been nothing but try to treat me like ****. They offered to swap my car for a new one since they cant fix the car but wanted me to pay $1,408 to do so. My favorite part is the ***** general manager goes "Even if we gave you a new cobalt, your driving would blow that map sensor too." all I could say was I forgot I bought an aveo and not a cobalt ss. **** Stonebriar Chevy and **** all dealerships. Just claim everything you can :P

 

what a ********. **** all stealerships.

 

What will happen if the dealer reflashes the ECM when the car goes in for service?
