Muscle Cars & Trucks reported a few days ago on the advanced encryption written into the ECU in the 2020 Chevrolet Corvette. The condensed version is that, according to the outlet's source, "successfully flash-tuning, reprogramming and otherwise altering the engine control unit to increase power output will be next to impossible." During the reveal event for the Cadillac CT4-V and CT5-V, MCT asked GM President Mark Reuss about the Corvette's new Global B electrical architecture, which is shared with the new Cadillacs, and about that ECU.
The context is that the Global B system has been designed to serve the next decade of GM vehicles, capable of supporting advanced driver aids like Super Cruise, full autonomy, far greater and constant connectivity that enables features such as over-the-air updates, the growing importance of cloud computing, and electric vehicles. Reuss' comments have to do with the primary threat to such a system: hacking. Calling the cybersecurity component "very, very robust," Reuss told MCT, "Global B I think is going to be the standard of the industry in terms of the encrypted messaging that travels on our bus between modules. There's a clean side and dirty side to that.

The above was discussed at length in another thread. Bottom line is that the Global B System is a completely different ball game than just hacking the ECU that was in the C7 ZR1. Find and read the thread. Those that think they are going to buy the base car and do a lot of performance mods need to educate themselves concerning this massive change in the C8 and all new GM vehicles going forward. The days of just hacking a Corvette ECU have ended and going forward, performance mods, if even possible at all, will be outrageously expensive.

I can't wait for this... Imagine a 600hp Cammed Mid engine exotic looking car... It's never been done before.
