  Modern combustion engines incorporate a number of actuators and sensors that
can be used to control and optimize the performance and emissions. We describe
a semi-automatic method to simultaneously measure and calibrate the actuator
settings and the resulting behavior of the engine. The method includes an
adaptive process for refining the measurements, a data cleaning step, and an
optimization procedure. The optimization works in a discretized space and
incorporates the conditions to describe the dependence between the actuators
and the engine behavior as well as emission bounds. We demonstrate our method
on practical examples.
