Pops and bangs is the common term for extra exhaust sound on the overrun from retard ignition and extra fuel injection which burns through the exhaust system.
Parameters
Enabled - enables/disables pops and bangs
Comfort / Sport / R Mode - enables/disables for each mode.
Duration - the duration of the ignition cut / extra fuel in milliseconds.
Tables
Retard comfort / sport / r mode - absolute ignition timing in dgrees after TDC.
Note this is different from the Fl5/DE5 where the table value is subtracted from the ignition table. For the FK8 the ignition timing from the retard table is used. eg If the table values are 25 degrees then the timing will be -25 degrees.
Fuel cutoff delay - the delay before the fuel is cut on overrun, by gear and rpm
A longer delay will give longer pops and bangs but will surge in lower gears and use slightly more fuel.
