Tunners Hack C8 ECM

twin turbo c8

Tuners that specialize in modifying the engine control module (ECM) to increase the engines power have been able to “Jailbreak” the unit.

Up to this point, tuners had to use what is called a piggyback system. These systems go between the ECM and the sensors on the car to trick it into making the changes the tuner wants. These systems are very tricky and hard to program. If you have followed Emelia Hartford and her world’s quickest twin-turbo C8, this is the type of system she used to get the ECM to work with the modifications.

Why did tuners need to Jailbreak the ECM? Well, as cars become more and more controlled by onboard computers, cybersecurity has become more important than ever. We don’t want hackers being able to get into your cars computer and apply the gas or brakes for example. So GM designed the ECM to be locked down to unauthorized access. For security reasons GM also locked out long time tuners like Callaway and even Hennessey.

Now that tuners have found a way into the ECM, they can modify almost every aspect of the engine including handling boost pressures if turbos or a supercharger is installed, air/fuel ratio, injector timing, and other parameters. This will open the market to bolt on turbo and supercharger kits over the next year or two.
