Is tuning possible, yet?
When the C8 came out there was no way to tune the car. I have seen a few twin turbo kits and supercharger kits. How are they adding additional fuel to not go lean? Is it an external fuel management system? Using an old school adjustable fuel pressure regulator?

For right now, the C8 responds to just bolt ons while naturally aspirated and gains a decent amount of horsepower. It appears that ECU adjusts to the bolt ons without any issues. Other members will chime in with more details on this matter. But with the superchargers or turbos, the shop are using of which they call a "piggyback " of some sort to enable them to tune the force Induction.

They use a piggy back system. But with extra injectors. The stock injector can not add enough fuel to compensate, for turbos of blowers.

The piggyback systems kind of already do that. They're just insanely expensive. Pietz's kit is like $4,000. Not sure if FuelTech has released theirs to the public yet but I'd imagine it would be around the same price.

I mean -- even the C7 ZR1 still isn't tunable natively. Doesn't it still require physical modification of the ECU, or a different ECU all together? If we haven't cracked that one yet and we're already into the next generation, chances are we likely won't crack the c8 any time soon, if at all. We don't even know if OTA would revert the computer back to stock if it's modified yet.

It was never for everything in 96. How'd that go?
It was never again in 05 for CAN. Nope.
Dodge was never in 2011, then again in 2013, didn't work out.

It’s 3 years guys Diablo said it lmfao
On a serious note this has been going for decades from the oems, they tell everyone you can’t tune or hack it and it’s really about warranty worries a lot of the times. They don’t want the hassle of fighting over tuning claims, dodge is well known for being bad about that. But nothing beat the GTR for making the aftermarket mad, Cobb spent almost 10 million dollars hacking the r35 and boy did they get alot of thumbs up for it. I think the primary issue is going to be how much of a market is there for tuning for the c8. Unlike the mustangs, Camaros, Subarus of the world. I don’t see the demand being super super high unless you’re the only one with the keys. I think that’ll be the big bottle neck more than actually getting some white hackers to get into the ecu IMO

Still no tuning for the C7 ZR1, except for complete ECU replacement. That probably won't work for the C8 because of even higher security in the inter car communication between modules, mostly the transmission control unit. The integration with the DCT is very important.

It’s worse than that the dash and HVAC won’t work either, nor will any driving aids. Chevy has said as much which is why nobody is buying blank ecus

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.
