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 […]
