ZR1 cost is also due to a very small market to recover the time to break the ECU. C8 will have a much larger market to spread that cost around.

That's very true. Probably what?, only a few hundred ZR1's if that potentially would be unlocked, where there will be thousands of C8's more then likely if possible to unlock.

True but your forgetting that the C8 is rumored to get OTA updates to the ECU which will make it a PITA.

I would think one would want to disable OTA if they want a custom tune anyway. Either way - it's comparing 3000 LT5s to tens of thousands of C8 LT2s.

It most likely will require modifying the ECU like they did with the E99 but your right I am sure the larger market will be added motivation.

Sure but that don't stop them from using tm to soften the hit of the next gear to A- make things easier on the shift. B- help the driver maintain control. C- more components involved than just the trans so it's only as good as its weakest component. D- axle protection anyone??? Been a staple a timing pulling tq robbing bs since it's inception. And likely one of the main reasons behind me saying you ain't turning it hard enough.

Yes it has steeper gearing. All the more reason for tm to intervene.

I know on the BMW stuff(both front engine), the Manual cars still dyno higher then the DCT. That is because the DCT is a wet clutch system where a Manual car is dry.

The ZR1 took some time to crack with a Global A ECU architecture, the C8 is suppose to get Global B. I am guessing somebody will find a way but if it costs what the ZR1 does to unlock that is going to suck for sure.
If you think the ZR1 is bad the GM diesel's are around twice as expensive to flash, $4000 just to get a reflashable ECM.

I'm sure it has some TM built in...historically though, TM has hindered launch and 0-60 times (6th gen ZL1 might be the worst). That said, the 2.8 sprint to 60 is quite decent given some possible TM on the factory tune.

Guarantee it has a **** ton of TM

and I’m still just not understanding those of you who are disappointed with a 123 trap at over 3800 raceweight and 495 hp. It should actually be a bit lower imo

c8 has exceeded almost all my expectations so far. It is a bit heavy. And I’ve also read they held back on the handling a bit to protect the average consumer. It has a bit of understeer. Supposedly because a mid engine car like this can easily end up with the rear end pointing toward the ditch in the wrong hands. Understandable

Historically the thing that hindered launch was traction. As the c8 is a great example of how traction beats hp/tq in 0-60. Alot of time the tm was there to help one stay in control.......due to the lack of traction.

Tm is no doubt still there....and probably faster reacting to manage the power vs traction better. Just remember the tm is also there to help make is easier on parts to. That boosted camaro chihuahua ran the other week was a great example of tm still intrusive on shifts. .....which is something you'll never see on a dyno. We seen it on phil 1le vs poppa 5br0 to. It's been involved in phils vette till it got turned off. It's a top end killer and greatly hinders momentum from gear to gear.

C8 will probably pick up 5ish mph with just a tune. Maybe more.

It still will most likely end up handling better than any Vette they have built. Just wait till the rumored DOHC motor hits high reving V8.

It can handle better no doubt. They playing it safe with the first base vette

its already almost a full second faster than last z51 with understeer tuned in

At the end of the day one has to use some logic. If GM could get 650hp at the crank from a NA 6.2 engine and pass emissions they would have never put a supercharger on the LT4. 650hp is what a decent Heads/Cam LT1 makes with a cam that has overlap and a exhaust setup that won't pass emissions. The LT2 isnt making that kind of power plain and simple.

I agree but I won't be disappointed or surprised if it makes over 500hp NA

I don't see a LT2 making 80-100hp more then a LT1. There wasn't enough changes to the LT2 to support that much power gain. They share the same bore, stroke, compression, heads, throttle body. The only difference is the Intake manifold, oiling system, slightly different cam, and exhaust.
