Pops & Bangs/ Crackles/ Burble
We have had an increasing number of requests for Pops, Bangs, Crackle and Burble maps on Petrol vehicles.
Pops and bangs are generated when an explosion echoes in the exhaust. This is either fuel touching the hot exhaust before exploding, or an explosion happening earlier in the system and reverberating through the exhaust. The most common way of achieving this is by retarding the ignition timing so the fuel/air mix ignites later in the engine’s cycle. If timed correctly, the exhaust valve will be opening to allow gas, along with pops and bangs to escape. This is what most commonly gives you the effect.
However, it is important to ensure you are aware of the potential consequences as if the vehicle is Stock with all of the catalytic converters present due to the way in which Pops & Bangs are achieved they will be detriment to the CATS and inevitably lead to premature failure (also the results of Pops & Bangs will be somewhat limited should the vehicle still be fitted with CATS).
