The term 'backfiring' describes any instance where car fuel is combusting somewhere other than the combustion engine. While this is usually something you'll want to avoid, an explosion in the exhaust or air intake systems will have a pretty impressive effect. With your car roaring, with flames and smoke strutting out its back, you'll be able to get your car looking like a drag racing monster! Keep in mind that backfiring a car can be very dangerous, so it's generally inadvisable unless you really know what you're doing.

  1. Step 4 Access and change the injection rates in the ECU.
    This is where it comes tricky, as it requires you have an existing knowledge of your vehicle's specifications. You want to figure out what engine RPM you want for your car to start backfiring. If you just want the roar and pop of a backfire, choose an RPM to cut all fuel. Input a higher number for a given RPM if you want the flames. It goes without saying that adding extra fuel is more dangerous; if you're relatively new to this, it's recommended you experiment with the safer route first.
    • Although the particulars will vary depending on the model of car and type of ECU kit, generally speaking, you will want to access the input and cut fuel intake at the RPM you'd like your car to pop at. If you're using a Flash Tune Kit, for example, input the given RPM intake as the most negative integer the system will accept. Input these negative integers (e.g. -15 etc.) to encompass the range of a couple hundred RPMs. This will essentially 'trick' your engine into popping.
    • Entering a number incorrectly could inadvertently destroy your car. It is not recommended you even consider doing this without some expertise in motorworks.

Warnings

  • Backfiring engines are incredibly loud, so it's best to do it somewhere where noise isn't a problem.
