Double-click on the Mapped Core Engine block to view the editable predefined speed and torque breakpoints, and corresponding look-up tables and output port names for the power, airflow, temperature, efficiency, etc.
The Mapped Core Engine block models only the engine. The throttle dynamics that result in the input TrqCmd to the Mapped Core Engine must be done outside the block.
For more information on the mapped Core Engine block, refer to the example here. Also check out this video on the powertrain blockset. It covers mapped blocks.
