ENGINE DISPLACEMENT

    Engine Displacement

Defines the cubic inch displacement of the engine. This parameter us important because is defines how load is calculated. The VE(Load) is calculated by the airflow, the RPM and the ENGINE_DISPLACEMENT. Engine_displacement/(Airflow/RPM) = VE(load)

Increasing ENGINE_DISPLACEMENT typically causes increased ignition advance and leaner mixtures. This parameter is closely coupled with the MAF_FUNCTION. Double this value, and you halve the calculated load value—that means leaner fuel mixtures and more timing. Be careful here!
