POP AND BANG OR CRACKLE FOR YOUR CAR

‍

Pops, bangs and flames; everyone likes that, don’t they? Well, hell yes you do, and because of this, ECU remaps that make your exhaust pop, bang, and kick flames from the tailpipe when you lift off the throttle are hugely popular these days.

For those of you who remember some of the supercars of the ’80s, you will recall the amazing sound of liftoff over run burble and popping sounds of the Ferrari F40 along with the pops and bangs of a Sierra Cosworth or Escort Cosworth.

For the younger amongst us, there is YouTube and thousands of hours of these cars making awesome sounds out of the rear of the car.

Moving forward to the present day you will no doubt have heard the F-Type Predator 650hp screaming through tunnels and upsetting most hypercars out there for not only speed and acceleration but also the pure filth of the over-run pop and band and even some crackle.

Through the continual advancement and development of tuning software, Custom Motor Tune is able to offer this supercar level of Pops n Bang to virtually any car.

Whether you have a Ford Fiesta, Focus ST, VW GOLF GTI and R, Megane RS, BMW 1/2/3 series (the list goes on)

What is a pop and bang map?

The exhausts of heavily-tuned cars have naturally popped, banged and flamed since the dawn of time, but have you noticed lately, a lot more cars than ever before have been popping and banging from the exhaust when the driver lets off the gas? Mildly-tuned motors and even quite a few factory production cars now have a cool burbling exhaust on the overrun. This is because lots of tuners and manufacturers have realised that owners love these kinds of noises. And with modern engine management being so damn capable, it means that they are now commonly mapped into the car’s ECU tune.

When you accelerate, your exhaust produces wonderful roaring sounds we are all used to. However, when you decelerate, the sound disappears with the speed. Pops and bangs make deceleration sound even better than acceleration.  As you lift your foot off the throttle, your exhaust starts popping, crackling and gurgling, which adds a whole lot of fun and character to driving segments that used to be devoid of any pleasure.

Similarly, if you have pops and bangs tuning file installed, when you shift gears, you will no longer experience a drop in sound when you shift up. You can mark each shift with a loud pop & bang.

Can pop and bang maps be applied to any engine? 

In a word, no. But it can be done to a hell of a lot more engines today than ever before. In theory, it can be done to any petrol engine – normally aspirated, supercharged, or turbocharged – anything that has an ECU with which the fuel and ignition settings can be heavily modified, which these days means most of them.

Some cars can have their ignition retarded further still, and allow the ability to open the idle valve or open the throttle a little, all of which can provide more extreme pops and bangs, if that’s what you want. So, providing you can find a tuner capable of adjusting your ECU to suit, the vast majority of engines can have this applied to some extent at least.

IS POPS AND BANGS TUNE SAFE?

As an approved Viezu remapping dealer all our ECU files are custom to your vehicle, well tested and not taken too far, which allows pops and bangs completely safe. In fact, many manufacturers offer pop and bang sounds as a stock feature for their cars and they come with regular warranty and safety claims. These include some of the most famous manufacturers such as Mercedes-Benz (especially for AMG cars), BMW and VW and other VAG models. So, yes, pops and bangs, if done right, are completely safe. Otherwise, they would hardly find their place in regular production cars.
