Is tuning possible, yet?

it will never happen without GM's help. You are talking 64bit encryption technology to today's 512bit encryption along with the CANBUS secure network. As said you still cant tune a C7 ZR1 E99 ECM (same ECM the C8 uses) natively, you can only tune it with a hacked ECM that costs $4500 to be able to tune. No many are going to spend $4500 to tune their C8 for bolt ons.
Right now I can name 10 of my customers that will pay $5k to be able to tune the C8. Me included,would love to be able to forge,boost this motor if we could tune the factory pcm.

i agree......the fastest bolt-on N/A posted a 10.33@129 down in Florida. The same car is now trapping 131s enhanced with a airbox mod. Makes you wonder how much more a tune would do.

Must be an AFE or Green air filter then? The AttackBlue and K&N filters retain the partition similar to the OEM filter. In dyno testing, it appears the partition really doesn't matter though since the AFE filters show higher peak power than the AttackBlue. Maybe at speed it makes a difference with increased air turbulence? I'd like to see AFE vs. K&N eventually...

If that doesn't convince you, just look around at how many manufacturers are expecting to derive revenue from subscription based software services. They're gonna lock that **** down if for no other reason than to insure they get their monthly tithe from the cars'

And the encryption is VERY heavy duty. Not really breakable by any reasonable means. It would take literally hundreds of years to crack using readily available supercomputers. Now then, if someone comes up with a truly useful quantum computer, than easy-peasy.
Not if you understand anything about modern encryption techniques.
And please, no one start comparing the C8 to the ZR-1. Many orders of magnitude difference in the encryption.

Good opportunity for the factory tuning team to learn a few things as the model years progress then sell us a Chevy Performance tune at the dealership. They sold updated suspension tuning for the C7 so might as well sell engine tuning too. My guess is we'd line up to pay $500 for an update that offered a little hotter tune for additional power, etc.

As you said, that won't work on the C8 because of the inter-module security routines. They'd reject it like a failed organ transplant.

And apparently nothing was given to Callaway regarding their latest C8 Equipment GROUP package.....only the ported intake manifold and their Honker Intake. So that could be a sign right there that nothing from GM is forthcoming anytime soon.

If you need more evidence that this isn't like before, GM is looking to monetize the car's digital infrastructure.

Safety and security are the buzzwords they're using to explain why everything is being locked down, but the real reason is revenue.
It's the same thing with the electric car push. They want a piece of the charging network revenue.

I have been following this along since the C8 was introduced and I hate it but I will just not ever be a C8 owner until I can modify and tune. That may mean I will never have a C8 and that is fine. There are plenty of other performance cars out there to play with. Since the C8 was still locked down, I ended up buying an AMG and have been having some fun lately.
