I have mentioned this over the past several months. I could easily see the big tuners paying $$$ to be GM Performance Certified (just made that up BTW) or something after they have made agreements and have some equipment purchased by GM to maintain the security built into the car with OTA updates and such.

I believe this was said during the NYC interviews, but I can't seem to find the video. I have not seen it written down. It was discussed when they were talking about the aftermarket and how the new ECU will play with that. I would imagine there will be something in the future that will allow for tuning by aftermarket vendors. GM sells crate motors and all sorts of performance related items. I can see them selling you an ECU that is compatible.

If not, stand-alone ECU's will become popular.

oh yeah, and the orig. owner signs this dumpy deal and sells the car two months later. next owner: the stuck-ee? when s/he goes in for warranty work. oh great idea among the others reasons why not-to do this listed above.

Apparently the OP did not see the video interview from the NCM Bash with Tadge and Harlan where he pretty much said it best. What the heck is the deal with the first 2700 people getting their new vettes which are AMAZING out of the gate, they are essentially base model or base+ cars, and all these Youtubers and bloggers are tearing up their cars, putting super chargers, twin turbos, nitrous, wife bodies and everything else on them within 5 minutes of getting them. Seriously! The man most responsible for this car was beside himself. And I agree. This car was built to be enjoyed as it is. Granted they want to appeal to a younger audience. But those guys do their mods and then 3 months later it’s the next car they have to show themselves ripping apart. I get that there’s a segment of buyers who are all about having all the mods they can get so their virtually one-off car is even more outrageous and unique. But getting mad that a car that has only had 2700 units produced hasn’t had its tuning abilities unlocked for ALL the customers that want it is just nuts.

Either wait for them to unlock it which I’m sure they will when more cars are on the road - and then have at it. Or do what you really should do, and get a 2023 Z06, 2024 ZR1, or if you can afford it, the Zora. Why people want to rip up a brand new car is just beyond me. I get it if you just can’t wait to track the car and want to push the limits of the Z51 on track. Clearly that car is never going to have a long shelf life. But it’s just crazy to me all of the people who are buying this beautiful car and from day one covering it in giant vinyl wraps with Captain America crap on it or, even worse, doing something that voids the warranty on a first year car.

I get it, I’m showing my age (50) finally. And you buy the car, you should do what makes you happy with it. Just frustrating to those of us still waiting to finally own this already legendary car Hearing people complain that they really are pissed GM won’t let them take their new car and mess with something in weeks it took engineers 7-8 years to get just right. But hey, what do I (or Tadge) know.

Took me bit to remember where but I knew I remembered seeing something on 'someone having a way around ecu".
https://www.hagerty.com/media/news/p...nearly-700-hp/

No i dont believe everything, or most, of what I read on internet and the wording would lead me to believe they are not accessing ecu, Still peaked my curiosity.

EPA~ Hello, GM.
GM~ Hello, EPA.
EPA~ We understand that you allow owners to tamper with your certified emission systems.
GM~ Well, they signed a paper absolving GM for what they might do.
EPA~ That is against the Federal law. We fined Harley Davidson $20 million for this. We fined Chrysler $50 million for this. We fined VW a coupla billion for this. What do you think we're gonna do to you?
GM~ Let us "pass"as we have signed papers?
EPA~ Nope. Not just NOPE, but a big, steaming bucket of NOPE!
GM~Well, how much is it going to cost GM? The stockholders are not going to be happy about this. The 'rona really beat up our bottom line this year.
EPA~ We are not concerned with your bottom line.
GM~ Yeah but...Rkreigh said it would be a "win-win" for everybody. And he's on the "CorvetteForum."
EPA~ Well, maybe a "win-win" for the EPA, but not GM.
GM~ How can we rectify this?
EPA~ In the future, DO NOT ALLOW ANY ECM's to be "tamperable" and we just might let you stay in business. Otherwise, see VW...

There you have it, pretty much.

And this is the "good" outcome, when dealing with the EPA...

Whats the premium gonna be on the Z06 over a base car? 30 grand?

Just because someone can afford a c8 doesn't mean they can also affird a Z, ZR1 or whatever.

Red Mist Rulz

It is simply illegal to modify the emissions equipment. Period. That includes the exhaust. Whether it passes the specific tests is immaterial. The fines amount to big bucks, and the EPA is getting more serious about enforcement. GM may, eventually, allow tuners to unlock the ECU. But you can bet the contract will require the tuner to offer their own engine and drivetrain warranty equal to GM's (like Callaway dow now), and perform their own emissions certification and get Fed approval.

Red Mist Rulz

The ZR1 doesn't have Global B nor anywhere near the level of encryption of the communications between modules the C8 does. Assuming that because they cracked the ZR-1 they can crack the C8 is nonsense. It's like saying that if you can crack a 4 digit pin on my phone you can also crack a 128 byte long password encrypted with 256 bit AES encryption on my server.

Red Mist Rulz

By whom? And no, the E99 hack won't work on the C8.
LOL. You really don't understand anything about what you're posting about. Global B is a whole new ballgame, with a whole new level of security and encryption. Every computer module in the car communicates with every other module via an encrypted stream, and there's a handshake each time to validate that the signal is coming from a valid encrypted node. Every car has a unique key. AND that key changes continuously.

Here's a primer that might help you understand why the C8 isn't going to be "cracked" the same way the ZR-1 was:

johnodrake

there is no software that can’t be hacked. All it takes is time and money. The issue is who will take the time and spend the money

Shaka

Or bi passed. Simply loose the un hackable parts. Check this vid that covers hooking up a Haltech ECM that integrates to any other OEM factory control systems. There is an 8 part video of the build of this car for those who are so inclined. There is something for everybody here including hooking up a manual transmission to a mid engine LS engine, turbos and one video covers electronics.

meadowz06

Yep.

RapidC84B

That's false... the E99 ECM in the C7 ZR1 has a work-around, but nobody has figured out how to tune the C8 and still work with Global B.

mschuyler

How many people does this affect? How many C8 owners want to immediately tune their cars? How many C7 owners have tuned their cars? Do we know at all?

shiumai

Typically someone who modifies a car with forced induction, tuning and the supporting drivetrain mods, and also assumes the risk of the factory warranty voided on the affected components (which can be expensive if they blow up the engine etc) has disposable income to do it. If you add all that up, it's going to approach the cost of the next level model. And, if they have the patience to wait for used ones to hit the market, they'll certainly be able to afford them then.

SurfnSun

This is the worst attempt at drawing a parallel that I've seen in a very long time.

K-TownMike

You are talking about a full on FI build. There are plenty of guys who just want to throw on a blower for 8 or 9k and have it tuned and not go crazy. That isn't anywhere near the price of a Z.

Also, there are even more people who just want to go the bolt on route and be able to tune, for less money still.

A quote directly from Mark Reuss.

“(2020 C8 Corvette ECU) is very, very well done in terms of being able to connect,” Ruess continued, “but also to have the capacity and capability for things like Super Cruise, AV and EV. That pipeline that is created with Global B and cybersecurity to be part of that is very, very robust.”
