With increasing complexity of engines, calibration effort is increasing which is reflected in the number of calibration labels in an ECU.
The goals of the new calibration methods are
Performance increase to reduce calibration times
Moving from steady state experiments to transient calibration
Better reproducibility of test runs

The rapid calibration access enables us to increase the number of intermediate calibration steps, thus reducing the required set time
The increased number of intermediate calibration steps leads to a faster stabilization time
The overall calibration task can be reduced by ~30%
