Adding Tables to a Tradeoff Calibration

The models of torque and NOx are in the current session. You must add the lookup table to calibrate.

Both models have five inputs. The inputs for the torque and NOx models are

• Exhaust gas recycling (EGR)
• Air-fuel ratio (AFR)
• Spark angle
• Speed
• Load

For this tutorial, you are interested in the spark angle over the range of speed and load.

To generate a lookup table for the spark angle:

1. Click . This opens the Add Table to Tradeoff dialog.

   

2. Enter Spark as the Table Name.
3. Enter Speed as the X Name and Load as the Y name.
4. Enter 13 as the size of the speed axis.
5. Enter 10 as the size of the load axis.
6. Fill the Speed axis with N and the Load axis with L.
7. Fill the table with SPK (spark angle).
8. Click OK.

Before you can perform the calibration, you must display the models.
