WHAT IS A POP AND BANG REMAP?
The exhausts of heavily tuned cars have popped, banged, and even produced flames naturally as a by-product of the tuning, but have you noticed lately, a lot of cars that you would not normally expect to pop and bang, are doing just that.
We can add pops and bangs into a performance remap and although it is not an option we push, we realise that some customers do want the pop and bang feature, so it is one we can provide at a customer’s request.
A pop and bang (or burble as commonly referred to by manufacturers) is a calibration feature within the ECU where a specifically targeted, very lean misfire happens as you lift off the throttle.
CAN POP AND BANG MAPS BE APPLIED TO ANY ENGINE?
NO, but in theory, it can be done to most petrol engines, turbocharged, supercharged, or even normally aspirated, that have an ECU in which the fuel and ignition settings can be modified, and providing you can find an experienced tuner capable of adjusting your engine management software correctly, most engines can have this applied with varying degrees of effect.
Because a pop and bang map requires adding more fuel, you can only safely have it with a catalyst-free exhaust.
STANDARD FACTORY TUNED VEHICLE
Previously pop and bang only featured in heavily tuned cars, but with modern engine management capabilities, pop and bang can be mapped into a performance tune for many (but not all) factory standard vehicles.
The feature offers no performance advantages but does offer a sportier feel and noise and results in pop and bang or crackle noise coming from the exhaust system during engine deceleration.
Fire coming from your exhaust tips will turn heads at car shows and of course on the road (although we recommend you only do this on private land or at car shows where permitted)
You may need modifications to allow these (typically de-cat) methods such as adjusting the air to fuel mixture, anti-lag and ECU remapping on ignition parameters should be done with associated parts.
ARE POP AND BANG MAPS SAFE?
This is the most controversial element of pop and bang maps but providing your map has been done by someone who knows what they are doing, it's highly unlikely to cause any real issues.
