Pop & Bangs (Rev Limit Crackle)

Add aggressive crackle and pop sounds to your exhaust on throttle lift for a more exciting, motorsport-inspired driving experience.

What is Pop & Bangs?

Pop & Bangs tuning, also referred to as rev limiter crackle or exhaust overrun tuning, is a performance-oriented ECU modification that creates controlled combustion effects in the exhaust system. These effects generate aggressive sounds—such as pops, bangs, and crackles—when lifting off the throttle at high RPM.

This tuning style is popular among car enthusiasts and motorsport fans who want a more dynamic, race-inspired sound experience from their vehicles.

How Does Pop & Bangs Work?

To create the pop & bangs effect, we modify your ECU software by adjusting ignition timing and fuel cut-off parameters. These adjustments allow a small amount of unburned fuel to ignite in the exhaust manifold under specific conditions, typically when decelerating or engine braking.

At MetaECU AI, we ensure this process is safe, calibrated, and engine-protective, using AI-powered tuning logic to match your vehicle’s characteristics and engine type.

Benefits of Pop & Bangs Tuning

  • Custom exhaust sound on throttle lift

  • Adds motorsport feel and style

  • Fully configurable activation range (e.g., 3,000–6,500 RPM)

  • Safe for turbocharged petrol engines

  • Reversible tuning (can restore to stock anytime)

Who Should Use Pop & Bangs?

This tuning is ideal for:

  • Enthusiasts with performance exhaust systems

  • Petrol-powered, turbocharged cars

  • Show cars or track-day vehicles

  • Drivers seeking more personality in sound

Pop & Bangs is not recommended for diesel vehicles, daily drivers in urban areas, or cars with stock catalytic converters (due to possible damage).
