Are you are suggesting that whatever way they do it will become public knowledge?

ECM Change?
I'm not an expert on tuning so don't go to town on me. I'm assuming most of us who own a C7 ZR1 would love to modify and tune it for their own reasons.
Is it possible to either ask GM/Chevrolet for the code to the ECM in your own ZR1 or, purchase a new ECM that allows you into the ECM in exchange for voiding the warranty?
To me it sounds like an easy question; perhaps it's just wishful thinking.
FYI, I did not see this question posited in this thread/forum, if it was, my apologies for not paying attention to detail.

I've actually heard that the ECU will, via wifi, reflash itself to stock. Supposedly it compares to see if anything is different from the current version from GM every night/week/whatever and flashes to that if it's not identical. Any truth to this?

I highly doubt that. It's too risky, fluctuation in voltage or an owner coming out to get something out of the car or even start and drive somewhere could brick the ECM, how can GM know what random thing a human is going to do?
Type to me slower, I'll try to hang on

We had this happening last night here in Finland with an export delivery ZR1. Might have something to do with russian hackers.

But, changing security keys over the air and encryption methods? Game on... Not only are you changing the locks but the type of vault.
I'm a little drunk right now, hopefully this made sense.

the new duramax uses this same ecu[or a variation of that number] and one of the tuners says they cracked it in the last couple months
and all these people that think they need more power,just turn off all the nannies,and try it that way,[99% of zr1/zo6/07 drivers couldn't keep the cars on the road]
ive been in a few real race cars and ultra exotic cars driven by the best pro drivers ,and they are a handful to drive

Yea they cracked the diesel boys a while ago... Problem if you want to call it that. Is with all the R&D to finally crack the code on these cars.... You're gonna pay some hefty unlocking fees/cost/credits. Compared to "normal" or what you may have in the past.

Supposedly THE hacker of hackers for these aftermarket companies is holding out for a million bucks to do it. Says he can but not for less.
Not enough ZR1s to offset the cost as of now.
But the new pickups use same ecu and I'm sure other gm vehicles are and will so maybe at some point one of the companies will pony up?

Not really. I spoke to RPM in Delaware, whenever someone either breaks the code or GM decides to reveal it, tuning the C7 ZR1 will happen when it happens. Either in a few days or several years.
One could buy a new ECM. I was told that was $15,000. Well, f*ck, if that's the case, why not but a new engine from LME and put it in? I guess that's what I'll have to do. Put in a 427 LME and save the LT5.
