There are six weeks until

at an event in Orange County, California, and that is plenty of time for more
. The
latest comes from Muscle Cars & Trucks
, citing sources as saying that “successfully flash-tuning, reprogramming and otherwise altering the engine control unit to increase power output will be next to impossible.” According to the story,
General Motors’ Digital Vehicle Platform
includes provisions to prevent
tuning for the new

MCT
alleges the anti-hacking encryption written into the electronic control module will block any attempt to “read, write, and/or replace the standard
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

Unsurprisingly, folks aren’t sure what to make of this report.
Car and Driver thinks the encryption MCT
speaks of is more about the anti-vehicle-hacking measures in the Digital Vehicle Platform, meant to keep bad actors from taking over a car. That would especially be true of an
, since the new architecture has been designed with the next decade of mobility advances in mind.
The idea of locked-down ECUs isn’t new. European carmakers have inserted code to keep aftermarket fiddlers out of their engine bays for years now. The
was billed as having an unhackable ECU when it launched. Even the current C7 Corvette employs measures to inhibit tuning. We see how things have turned out for all of those examples.
On the other hand, if we look at
ECM encryption from 2017 on its Duramax pickups and the next-order encryption on the 2019 Corvette ZR1, there could be something more substantive to the
MCT
report. GM began installing
on its L5P Duramax trucks in 2017, and in 2018 forums were still calling it uncrackable. Depending on your definition of “cracked,” versus “rebuilt,” Houston-based HP tuners unlocked the L5P, but it didn’t happen until August of last year and there are a ton of asterisks involved
according to a story in Diesel World
magazine. There’s also hefty cost – $1,800 to $2,500 to exchange a stock L5P Duramax ECM for a tuned version, and another
to flash the ECM.
The Corvette ZR1 encryption went even further than on the Duramax trucks, featuring VIN-specific
rolling codes and constantly evolving digital signatures
that can be changed or restored via
when alterations are detected.
John Hennessey said he tried to crack the E99 ECU
for 11 months but couldn’t do it, and
was about to give up on the ZR1

HP Tuners again cracked the code
apparently, but it didn’t happen until April 2019, and the ECU exchange is again spendy, from $2,000 to $2,500.
for the ZR1 came out that same month.
Nothing will stop tuners from trying, of course. But it’s possible the C8 Corvette will make tuning much harder than before.
