Switching
Long press on the title ‘Burble’ or ‘Pop & Bang’ to activate the mode.
Injection Amount
Higher values make the sound richer.
Lower values significantly reduce fuel consumption and thermal load on the engine and exhaust system.
If the value exceeds the recommended level, its color will change to red.
Tip: Do not activate Pop and Bang repeatedly (10 times or more) on a stationary vehicle, especially at the maximum injection level.
Ignition Angle
Ignition timing offset.
Move the slider to the right to make the sound louder, with pops and even flames.
If the value exceeds the recommended level, its color will change to red.
Torque Compensation
Torque caused by the delay in fuel cutoff will be automatically compensated by the ignition angle.
You can achieve an OEM-like sound by enabling this toggle in Burble, setting the ignition angle to 0, injection to 50% and duration to 300-500ms.
Duration
The duration of the Burble / Pop and Bang effect.
Shorter durations reduce the thermal load on the exhaust system.
You can adjust the value from 50 ms to over 3 seconds or disable this limit entirely.
Random Activation
The function will activate randomly instead of triggering on every throttle release.
Maximum Speed
The maximum vehicle speed after which Pop and Bang is disabled.
At high speeds, the exhaust sound may be hard to hear, so it makes sense to disable Pop and Bang to reduce fuel consumption and thermal load.
Setting the maximum value disables the limit.
Minimum Engine RPM
The function activates when the engine speed is above the set value.
PRESETS
You can save a preset to easily select your favorite settings next time.
Built-In Protections
If the catalytic converter temperature exceeds 900°C, the function will be disabled. However, the mode will remain active and ready to resume operation once the temperature normalizes. Keep in mind that on the vast majority of vehicles, the temperature is modeled rather than measured, as actual exhaust gas temperature sensors are not installed. As a result, if any component of the exhaust system is non-stock or a different type of fuel is used, the calculation may be inaccurate. For this reason, the protection can be disabled if needed.
Just like with mode selection, Pop and Bang settings provide feedback from the vehicle. If the setting value is not accepted by the vehicle for any reason, it will not change in the app.
If two control units are installed and one of them does not accept the value (for example, due to low battery voltage or if one unit is disconnected from the vehicle), the app will attempt to synchronize the settings across both units.
