Filling the Table by Extrapolation
When you have calibrated several key operating points, you can produce a smooth extrapolation of these values across the whole table.
When you apply the value of the spark angle to the lookup table, the selected cell is automatically added to the extrapolation mask. This is why the cell is colored yellow. The extrapolation mask is the set of cells that are used as the basis for filling the table by extrapolation.

The lookup table is filled with values of spark angle.
The following figure displays the view after extrapolation over the table.
Note Not all the points in the lookup table will necessarily fulfill the requirements of maximizing torque and restricting the NOx emissions. |
The calibrator could now take these techniques to further improve the calibration. That is not the purpose of this tutorial.
For a more detailed description of tradeoff calibrations, see Tradeoff Calibrations.
You can now export this calibration for the electronic control unit.
