Interesting. Where there's a will...MCT alleges the anti-hacking encryption written into the electronic control module will block any attempt to "read, write, and/or replace the standard ECU of the C8." If the ECU detects such an effort, and that "programming event fails," the Corvette will enter a "recovery mode" that requires a reboot. The coupe can be reprogrammed, but only by an entity with the proper encryption keys - meaning a trip on a flatbed to the dealer.
