Enrichment Duration
Enrichment Duration sets the duration for which the fuel is added. Through acceleration testing, adjust this parameter until you have reached a satisfactory engine response. You will need to move back and forward between Acceleration Enrichment and Enrichment Duration to get the best response.
Enrichment Duration is the number of power strokes fired with extra fuel being added. Normally set to 30. but can be reduced or increased as needed. For example, setting a value of 30 cause the enrichment to last for 30 power strokes which is equivalent to 10 crank revolutions.
When tuning the fuel maps at steady state, temporarily set this to 0 and don't forget to reset it back afterwards.
