Pop & Bang / Crackle Map
Professional ECU file service — delivered within hours
A pop and bang (crackle) map modifies the overrun fuel cut-off and ignition timing tables to allow unburned fuel to ignite in the exhaust system, producing the characteristic crackle and pop sounds. This is especially popular on performance petrol vehicles and can be calibrated from subtle (light crackle) to aggressive (full burbles).
