Table Properties

Table properties allow you to edit the precision of selected tables and normalizers according to the way tables are implemented in the electronic control unit (ECU). The ECU designer chooses the type of precision for each element to make best use of available memory or processor power.

To edit the precision of a table or normalizer:

1. Select Edit Precision in the Calibration Manager dialog box.

1. Alternatively, if you highlight a table in a feature calibration, display the table properties by selecting Table -> Properties.

2. Decide whether you want the precision to be writable, then either select or clear the Properties Read-only check box.
3. Decide the type of precision you require for the table:
• Floating Point (See Floating-Point Precision.)
• Polynomial Ratio, Fixed Point (See Polynomial Ratio, Fixed Point.)
• Lookup Table, Fixed Point (See Lookup Table, Fixed Point.)

The following sections describe these types of precision in detail.
