As you probably already know, the 6.2-liter supercharged LT5 V8 engine found in the 2019 Corvette ZR1 ships with an encrypted ECU, locking tuning companies out of the vehicle’s software. Experts were finally able to crack the vehicle’s super secure ECU (almost a year after its debut..) and allow companies like Hennessey to truly set to work on the 755 horsepower engine, but they may face similar roadblocks tuning General Motors products in the future.
Speaking to Muscle Cars and Trucks, GM president Mark Reuss said the mid engine Corvette C8 will feature the automaker’s new ‘Global B’ digital architecture. This advanced new electrical system, detailed by GM earlier this year, will allow the automaker’s future products to talk and communicate with each other. It will also enable the various systems on GM’s upcoming electric and autonomous vehicles, so it must be secure and safe against cyberattacks. That means the ECU will be encrypted like the 2019 Corvette ZR1’s, except with an even harder-to-crack code.
“(the mid engine Corvette C8 ECU) is very, very well done in terms of being able to connect,” Ruess told MC&T. “But also to have the capacity and capability for things like Super Cruise, AV and EV. That pipeline that is created with Global B and cybersecurity to be part of that is very, very robust.”
Does that mean tuners will have absolutely no access to the Corvette C8’s ECU? Reuss seems to think not, although it doesn’t sound like GM wants just anyone to have the keys to controls.
“I don’t wanna cut anybody out from an aftermarket standpoint, but we have to pick and choose who are the good guys,” Reuss said.
The 2020 mid engine Corvette C8 is slated to make its debut on July 18th, 2019. Stay tuned for all the official details.
