To achieve the popping sounds, ignition timing needs to be retarded. This ensures that part of the combustion occurs with opened exhaust valves, producing the characteristic pops and crackles in the exhaust system.

Please note that this effect generates high backpressures and EGT in the exhaust during lift off conditions: if the car is equipped with a stock catalyst it will be necessary to work with low increments on maps otherwise you can damage some engine components (turbocharger, valve seats, etc) or the catalytic converter.

The maps that manage the fuel cut-off during throttle release must be adjusted. This incluedes the overrun fuel cut-off delay maps and its switch.

The maps that manage the base, optimal and minimum spark advance have to be modded to obtain the desired effect.
