Tesla cars are starting to fight owners hacking their cars to unlock the performance-enhancing software lock that the carmaker itself is selling as a software update.
And for a few years now, Tesla has started selling vehicles with upgradeable but software-locked capabilities, such as the 75 kWh battery pack unlocked at 60 kWh or higher power outputs possible through software updates.
The latest example of this is Tesla’s official launch of Acceleration Boost, a $ 2000 over-the-air software upgrade that brings acceleration from 0 to 60 mph for the Model 3 Dual Motor down to 3.9 seconds.
The Acceleration Boost offer enables close to 50 horsepower for the Model 3 Dual Motor’s powertrain and cuts acceleration time from 0 to 60 mph to 3.9 seconds.
And earlier this year, a company called Ingenext launched a device that allowed Tesla owners to unlock the same capacity at half the price.
Model 3 owners have to connect a connector to the MCU, and they will automatically get a 50hp boost in addition to some other features from (Ingenext), such as (Drift mode).
But as was suspected, Tesla cars had begun to resist hacking, and some owners who had purchased the device had received an in-car notification after the latest Tesla software update.
The notice says: Vehicle has detected a modification that is inconsistent with the vehicle, and the modification could present a potential risk of damage or lockout.
The notification appears to remain stuck on the screen, but the car is still drivable.
Guillaume André, founder of Ingenext, said: Tesla has corrected its driver software update that allows unlocking the ability to update the software with version number 2020.32.1.
André explained that they sent a notice to customers warning them of the update and only 3 customers updated their cars before seeing the update.
Ingenext is now working on their patch to enable their customers to update without problems, and it will take a week or two to get the patch.
And Ingenext Company page Lets customers know whether or not an update is secure.
Many owners want a power boost because it is already in the cars they have purchased, and Tesla’s claim that the mod could do damage is odd given that they use the same code the company uses to boost acceleration.
