"Downgrade" the Engine to LS3/LS7?
1. Rumormill indicates GM has made the new ECU damn-near impossible to hack, and by extension, tune.
2. The LT1 adds a bunch of electronic "features" that increase both weight and potential maintenance requirements.
Solution:
Pull the LT1 engine and sell it ($$$$), drop in an LS3 or LS7 with basic bolt-ons to make up the lost power/torque, and an appropriate tuneable ECU.
Result:
Reduced weight, reduced complexity, similar performance, possibly small net cost (I'm assuming the LT1 will be in high demand and therefore comparatively expensive).
Requests for Information:
1. Did GM change how the engine bolts to the transmission? I'd love to keep the new 7-speed. What about engine mounts? Other engine accessories?
2. What sort of issues might affect how a C6's ECU interacts with things like the C7 digital dash, and the rest of the cars electronics in general?
Putting in an LS engine would require an ridiculous amount of work. Block won't likely bolt to the torque tube, direct injection fuel system is entirely different...by far, you'd lose countless systems in the process...
What is wrong with the people in this forum...jesus.
Back when OBD2 came out in 1996 people whined we wouldn't be able to tune cars (I owned a dyno tuning shop for many years). They'll figure it out...calm down....

Wait til someone hacks the flight systems of the 30k drones Obama wants flying 24/7 over our country, then uses them as guided missiles....party time...

The Best of Corvette for Corvette Enthusiasts
Risk averse? I'll be leaving my cushy military career and plan to start a business about 6 months from now. Given the economic climate that's one of the riskiest endeavors you can engage in these days...
Moving the industry forward? I'm eager to get my hands on some 3D models of the C7. I want to use my knowledge of CAD software (self-taught) + 3d printing + Carbon fiber to rapid prototype and manufacture bespoke aftermarket car parts (largely as a side-hobby, that's not my business interest). As much as I love computers, I'm always looking to simplify and streamline the electronics used in vehicles, which is why I've read up heavily on ISIS Multiplexing and Nvidia's new automotive Tegra chips.
So far the only worthwhile answers anyone has given are "block won't likely bolt to the torque tube" and "the ECU WILL get cracked, just wait". Ok. That was useful. Thankyou.
There's a lot more upside to the LT1 than downside. An engine that has taken lessons from the Gen IV engines and improved on them probably more than we will know for awhile.
I don't think people were trying to put LT1/5's from C4's in their C5's were they? Sh*t, what am I talking about, of course they were. The idea was dumb then too.
GM makes money and followers in the aftermarket. there is no reason they wouldn't want people to mod the car

I'd TOTALLY rip out that crappy LT1 and drop in a Duramax 6.6L!
Older audience? I just turned 30...

Sure, I can run an LS7 on ISIS on a wooden pallet, but that's not the point. The time that would be invested, in order to install an inferior powerplant, would be beyond wasteful. If you're starting a business, you may want to choose your ventures wisely.
Having been a shop for many years that installed swaps that didn't belong in certain cars, the immediate issues that come to mind are:
1. Mounts aren't going to work...forget that...need custom
2. Fuel system will need modified. Direct injection operates at pressures FAR beyond that of rail injection systems
3. The torque tube issue...need custom bellhousing
4. AC, PS, emissions systems, lines all need to be custom made
5. Biggest problem is management and system integration into the car. Like the racecars I've put LS7's in, there is no use of the EBCM, or any other module, because implanting all the necessary systems in another car would be nothing short of a nightmare. As a result there are workarounds...
6. Engine bay fitment wouldn't likely be a problem, but all these cars are going to be dry sump, therefore you may need a thin oil pan engine to fit, i.e. a dry sump type setup, which means you'd be looking at trying to convert an LSx to dry sump.
All this is speculative, having not seen or dealt with a C7, but it's likely that electronically speaking, you could have potential dash issues with certain readouts and things that are fed specific information via the pcm.
Essentially you'd take a C7, with a far more advanced engine, and slap in a dated powerplant, with far less of a usable power curve (due to vct), spend thousands upon thousands of dollars to do it, and devalue the car tremendously....
Go build a GTM or RCR SL-C, stick in your LS7, prototype all the little stuff you want, and spend 45k or so doing it (75k for SLC). Yes, they'll say less, but unless you're running a junkyard LS1 and beat bushing suspension...no.

All the naysayers just need to relax, take a deep breath and wait to see what the package offers.
You sound like a pretty smart cat.....here is a link to some of the encoding going on with the ECM.

As a mathematician that knows the ins and outs of the RSA algorithm used here, it is pretty impossible to crack, it is the same system used in internet commerce. But, like with most hacking deals with commerce someone will find a way to get inside the host computer and get the vitals.......interesting application of the best encryption methods we currently have though.
For those that are interested, the whole public private key method starts with two numbers that are 200-300 digits long, then goes from there. Ouch.
