What is a pop and bang remap? Schubabschaltung deaktivierung
The pops and bangs and crackle mod is also called exhaust crackle deceleration, exhaust popping, burble, car backfire, crackle map, anti-lag system (ALS), schubabschaltung deaktivieren, schubabschaltung knallen, schubabschaltung blubbern, schubblubbern or deceleration map and it results in those beastly bangs and healthy gurgles from the exhaust when the accelerator pedal is released.
Gives a real racing car experience.
Possible for every car and model.
Easy to add (and to remove).
How to make exhaust Pop and Bang
There are 2 modifications that result in pop bangs.
1. After the throttle pedal is released, the fuel delivery is not cut off immediately. It is delayed in order to provide fuel delivery during deceleration as well, schubabschaltung deaktivieren.
2. The next modification is a change in ignition timing which we retard. The ignition causing a flame front happens later than usual – even when the exhaust valve is opening – and this causes the flame front to take place inside the cylinder, but also in the space that connects the valves and the exhaust, thus giving the desired sound.
The main advantage is that during deceleration, the delayed combustion flow will also pass the turbocharger causing the turbo to keep its revs high instead of losing revs due to the lack of exhaust flow which would happen without the modification. Besides the soundtrack benefit, this also means that your car will be faster. This is so because the running turbo means that you waste no time spooling up when you press the pedal again. The reaction time is noticeably shorter and the turbo lag is virtually non-existent, so we also call this mod anti-lag.
Another perk that many of our customers opt for is having the same sound when the car is not moving at all. Pops and bangs are noticeably louder when the car is moving, but the sound at standing still unmistakably gives the hint of what the car is capable of when you finally get going.
Good and Bad side of Pop & Bang
Pop & bang sounds awesome! You can hear them when you lift off the throttle pedal during, deceleration or braking or when releasing the throttle between shifts. It definitely turns a lot of heads, but it also gives you the feeling of driving a hardcore sports car, since these kinds of sounds have usually been reserved for the top notch supercars. Well, now you can have them, too!
Secondly, for turbo engines, it adds another benefit of the mentioned anti-lag system, which greatly improves the reaction time of the turbocharger. After pop & bang modification, your turbocharged car will not only sound meaner, but it will also be faster and offer that amazing feel of continuous acceleration that many turbocharged cars lack.
All of the bad sides are inherent due to the pop and bang mechanism and the most devastating ones come from modifications that are not performed properly. If your pop & bang modification is performed properly, the risks still exist, but they are definitely not that dangerous.
The most devastating side effects for your engine include damage to the valves, turbine, and piston heads due to the explosions which happen at very high temperatures. These components outside the cylinders are not intended to ever get into touch with such high temperatures.
The same feature means that pop & bang Stage 2 is not the best option for cars that have stock exhausts with a catalytic converter. If you want Stage 2 Pop & Bang, you will need to remove the stock catalyst. Stage 1 Pop & Bang can be done on stock parts, including the catalyst and it will result in milder pops and bangs
Many people who understand how engines work think that the late ignition automatically means that performance is hampered, since the best moment for ignition is when the piston is in the top position, or just before that. However, this is not so. Matching delayed ignition with the moments of the low load means that this happens only when you lift your foot off the throttle pedal, so no performance loss occurs. In fact, even with the foot off the throttle pedal, high revs of the turbo after the modification improve the engine response and performance.
Is pop & bang safe?
Even though the mere fact that the explosions happen in the space that is not designed to deal with the resulting temperatures should mean that pop & bang is not safe, if the schubabschaltung modification is properly developed, it is safe.
In fact, many car companies such as VW, BMW, Mercedes-Benz, and Lamborghini offer OEM pop & bang feature and that one is bound to be safe. In most cases, this feature is activated in sports mode.
Being too aggressive with pop & bang modification can result in loss of power and serious damage to the engine, valves, turbo, and exhaust. However, thorough testing and measuring ensure a mod that is completely safe and sounds great.
This is why it is important that you choose your options wisely. We pride ourselves on our well-deserved and long-lasting reputation and we can claim safety on Stage 1 mods. However, due to their aggressive nature and varying levels of modification, we only do Stage 2 mods on your responsibility.
Is it worth it?
We keep getting an increase in orders for schubabschaltung pop & bang software mods and we are working overtime in order to keep our company at the very top of the lot when it comes to both quality and the number of ECUs we provide pop & bang for.
This high number of orders clearly means that our customers are satisfied. And the sound is just too good!
