Overrun Crackles

Overrun crackles, also known as “crackle maps” or “pop and bang” tuning, is a method of reprogramming a vehicle’s engine control unit (ECU) to create a more aggressive exhaust sound during overrun or deceleration. This is achieved by altering the engine’s ignition timing, fuel injection, and boost control settings, which causes unburned fuel to combust in the exhaust system, creating the crackling or popping sound.

Overrun crackles tuning is popular among car enthusiasts and those looking to improve the sound and performance of their vehicles. It’s important to understand that this type of tuning is more for aesthetics and does not increase the power of the vehicle. It’s important to be aware that this type of tuning may not be legal in some countries and can void the warranty on your vehicle.
