Global B is here!

RobZL1 · 06-20-2023, 11:30 AM

Looks like HPTuners figured out global-b (C8/Blackwing, etc)!

Yep, was only a matter of time. I remember people saying this one would never be cracked. This is a C8 and Blackwing post, not a ZL1 post for those that don't know.

RobZL1 · 06-20-2023, 12:10 PM

Yeah, not exactly ZL1 relevant, but figured a lot of people in here might be interested. I saw it on hpt, and thought I'd share.

Its good news for sure, just didn't want anyone new popping in wondering if it affects their ZL1.

certainly makes the ct5 blackwing more attractive especially if you can get a flex fuel sensor on it

CT5 Blackwing doesn't have the LT4 motor?

Same engine but different ECU.

Cool that the ECU is cracked! Wonder if we'll see C8s that are actually fast now. Peitz already had a cammed twin turbo and vengeance racing tt c8 is the show car for this update.

It appears trans tuning hasn't been unlocked yet which to me seems to be the biggest issue holding them back at the moment. Perhaps that too is a matter of time.

That's because HPtuners said themselves it would never be cracked nor had any interest. Said the same about unlocking the T93. I believe Trifecta actually found the exploit to unlock the global b bootloader. This requires sending the ECM in to be bench flashed. If I had to guess HPtuner spent some money for the exploit....could be wrong.

Yep, I remember HPT saying that as well. I’m sure a good chunk of cash or promised royalties are involved lol…

Yea, I remember news many months ago about Trifecta breaking the code but everyone dismissed it because it was Trifecta. I've used Trifecta tunes on my GMC Canyon and I was very impressed for a canned tune. I had never heard of Trifecta prior to that. Trifecta seems to have a decent catalog of tunes for GM vehicles. Either way, money fuels everything so with enough demand and cash, I have no doubt there are people capable of cracking any code.

There must be more to this story. I'm as far from a cybersecurity/encryption expert as it gets, but even I could write uncrackable code, or at least one that's not crackable without powerful quantum computers (that don't yet exist).

In the past the leading argument was that manufacturers didn't want to kill the aftermarket and therefore left backdoors or deliberately used weak protection, but I'm not sure that reasoning would apply anymore in this crazy world. Again, there has to be other good reasons (or rea$on$

)

I’m sure you’re right about the aftermarket…dead aftermarket means no passion for the cars being made. I, for one, have completely avoided the C8 since it wasn’t tunable. I find it interesting that now that C8 production is catching up, the big buzz has died down some along with dealer markups, all of a sudden it’s now tunable…

Writing your own encryption is an easy way to have it broken by others. Manufacturers don't use strong encryption because there is a trade off. Strong encryption uses clock cycles, which requires faster and more powerful cpus. So they go with slightly weaker encryption, that is good enough but faster because it saves them money with scale.

The problem with modern day vehicles is the inter-connectedness, that is probably what is taking the aftermarket longer to decode. They have to figure out how to reprogram the ecu without bricking the other systems.

That is probably true for us that visit these forums, but the vast majority of people don't change a single thing about their car from the time they buy it to the time they get rid of it.

All of my non car friends keep their car stock, hell even a good portion of people that buy these cars keep them stock, right here on this forum. People that mod are the exception, not the rule.
