Tradeoff Calibrations

A tradeoff calibration is the process of calibrating lookup tables by adjusting the control variables to result in table values that achieve some desired aim.

For example, you might want to set the spark angle and the air-fuel ratio (AFR) to achieve the following objectives:

• Maximize torque
• Restricting CO emissions

The data in tradeoff is presented in such a way as to aid the calibrator in making the correct choices. For example, sometimes the model is such that only a slight reduction in torque results in a dramatic reduction in CO emissions.

This section on tradeoff calibrations includes the following:
