Tuning and dealership issues

[PPV_2018]

1st. You think it's necessary to return your ecm & tcm to GM OE before bringing it to stealership for 'work on it'?
It's yours, NOT theirs. This should go without writing, except you seemed to need to read it again - hopefully this was not the first time you've read this.

2nd. If for whatever reason GM was going to write anything to your ecm and/or tcm,
a dealership would not (ahem) CANNOT read it first.
They would simply overwrite it.
Who inflicted upon you the impression that any dealership even has the ability, much less the prerogative, to read your pcm?Navy Federal is AWESOME.IFF the dealership overwrites your tune -
which they will NEVER read first, gottdamnt -
just read their newer revised update of the GM OE files for your vehicle,
then decide whether or not you want to put in your old tune, or apply your tune to the newer revised update.

Look i totally agree with what you are saying in theory, but how we look at it in the eyes of consumers is not the way a corporation all about a dollar looks at it, particularly a dealership or “warranty company” or insurance racket “company” .

What i am saying is, yes, it is your vehicle, not theirs (though since the name on the registration does not matter, the title does — it may actually be the bank or finance companies vehicle, not yours, depending on the situation) , and that’s all fine and well if you own it outright and are not trying to get warranty work done . . . But if you are trying to get warranty work done, then modifications that alter the manufacturing spec of something will most definitely void that warranty IF you get caught.

It’s the same way for everything else. If you alter the operation of an appliance, a firearm, a cell phone, anything other than manufacturer’s spec, chances are you void the warranty.. don’t matter if you “own” it or not..

That being said, no i have no clue if, how, or why a dealer would be able to detect a tune.. but the whole point of my post is if they suspect something’s up and can prove it, YOYO (you on your own!)

A BlackBear tune is undetectable in this generation truck.

I'd love to believe that, but I don't. Not saying I don't believe YOU, I don't believe BB. If the dealership reads key-cycles since the ECM was written, and it's an unusually low number, they'll generally void a warranty.

Now, if BB has somehow found a way around that, I'd be pleasantly surprised to find out how.

Well, all I can say is that I trust Justin and have never heard of anyone having a warranty issue after being tuned by him. I doubt he'd give away trade secrets but you can always ask! @BlackBearPerf
