[QUOTE=siffert;1570375953]Yes. Great price.



I see you "changed your tune"



this is the part i was referring to, Of course, if you are concerned about warranty you should discuss it with your dealer or don't mod your ride.

 

Why discuss this with a dealer? You no doubt would get a different opinion from each dealer. Some might "allow" headers, some may not, etc. Its quite obvious from reading this thread, that tuning is a from GM's perspective. Of course, it is also obvious from reading this thread, there are ways around that issue.

Folks who are concerned about warranty should here check first, see what others have to say and their experiences and then form an opinion. I will say your Corvette ecm "odometer counter" and "bookmark" claim has pretty much been proven

 

lets have the guys that sell this equipment come out with a statement "that GM can not tell if you have changed your programing" and we will cover the cost of repairs if GM says you have done this and can prove it if they are so sure about their position. also if this is such a sure thing why are people suggesting you go out a get a different computer to change out.

 

We already have had that statement of "GM cannot tell" and do not need that "cover the cost" . Really, I have yet to see ANY aftermarket vendors on these forums offer any "cover the cost of repair if GM says you have done this" for any kind of modifications on a C6, cosmetic mods included. Do you have any mods of any kind?-since you have zippo for a profile here.

 

Here is a guy on the G8board that did just that (not on purpose) and reprogrammed it back to stock before he took it in.

Touche!

 

if it is so undetectable why even get a extra computer like suggested here ?

 

If you have the ability to flash back to stock then you don't need an extra PCM but if you don't have that ability then an extra PCM might be the way to go. The problem with an extra PCM is that, for those with autos, the TCM is in the tranny and not easy to swap so if you have any tranny tuning done that would still be there.

 

I could only guess that Ford and GM have similar technology as far as pcm's are concerned. My fathers Ford diesel has been programmed with a handheld, and I flash it back to stock everytime he has a problem, which one time was a seized turbo that needed replaced, nothing was ever said about the computer being altered. Again, this was on a Ford and not GM.

 

Actually, I have an extra PCM and it is no problem with tranny tunes. To do that, you put the oem tune back into your oem ecm (which puts the oem tcm tune back in at the same time) and then switch to put your extra ecm in there with the original ecm tune. Even folks with HP Tuner still like to have an extra ecm since they use one for their tunes and another kept original if needed.

 

Well, if it were me getting my car tuned by a tuner, I could see buying an extra ECM and swap out the original (which is proven good/reliable) and pop in the extra, have the work/tuning done, and then *I* can get it back to the original tune (and the original, physical ECM), anytime, without the tuner, computer/software.

 

The reason you will NOT see any after market reprogrammer vendor come out and say that "GM cannot detect our tune-flashback and we'll cover the work if they do detect your tune reprogram" is that:

They are not going to endorse "perceived" fraud... I say "perceived" because all I want to do is get a few extra ponies out of my car, tuning the ECM in MY opinion should be covered by GM. I do think that putting headers/cam/porting/etc and modifying the hardware should void a warranty, but software mods should NOT void warranty.

But that's just my opinion.

 

So if some hack tuner thinks it's a good idea to run 40 degrees of spark advance at WOT with an AFR of 16 and you blow your motor, that shouldn't void your warranty?

 

remember if your tune changes the emission output you are also violating federal law. most installers now will not do any exhaust changes that move the cat converter because they are violating federal law and could be subjects to a big fine,ask katech. the people i know that do engine enhancements will now give you the headers to install and then bring it back for the rest of the changes.

 

Step up to the plate and be a big man. If you decide to tune or modify your car while its still under warranty and something happens. PAY for the repair yourself, simple as that.

 

If my radio, power steeering, oil pan gasket, yada yada goes bad while under warranty and I got a tune, you can bet on me stepping up to the plate to pop back in my oem tune and have GM pay for it.

While you are the of bolt-ons,
you are also an outlaw wanted by the

 

Well, things will be changing in the next couple of years. The EPA will soon mandate that your state be required to check CVN numbers during routing emissions inspections. This means that even if you pass all the IM240 rediness flags, if your CVNs are not correct you will not pass go and collect your registration tags. Now this may not be an issue for the average Joe with minor bolt ons that will pass emissions with a factory flash. Its the guys with heavy mods meaning camshafts, head work etc etc, that will not pass. So big brother is coming down on us in the future, so with some work, perhaps we can all stay one step ahead that big brother

As far as commiting fraud against GM, I for one think its wrong and I think I speak for most of us here. I beleive if you want to play you have to pay. GM shouldn't be responsible for any outsiders tampering or mods. They gave us a decent car to play with and for me that is where it ends. I modded my new Z06 with 1500 miles on it, in fact I went into the engine 3x to find that magic camshaft that I would like, warranty....what warranty. I just sent a brand new LS7 block down to So Cal to have Darton sleeve it with their ductile iron sleeves in preparation for the next round of mods. It will soon get a Turbo Technologies TTiX twin turbo system making around 900 to the wheels I know I can get it though emissions, well semi legally anyways. I can do this by installing stock injectors and carefully driving it down to the test station, with the cam I have going it I am willing to bet it will pass on the stock flash with the correct CVNs It should even pass a visual because the TTiX kit has cast iron manifolds and the turbos are tucked away close to the block, it will also have CATs and a full exhaust

 

^So cheating GM is wrong in your book, but cheating the state of Oregon is ok??
