4.1 Custom Input Lookup Tables
Many sensors used in cars have a non-linear response curve. This means that their output
voltage does not follow the measured quantity linearly but with some sensor dependent curve.
LogWorks allows you to enter points of that sensor curve (as many as 1024, the more, the better)
to convert the sensor output voltage back into the measured quantity directly. LogWorks
interpolates the sensor measurements between entered points.
Press the Load/Edit Table button in Field 10 of the Channel Configuration Dialog, and you will
be presented with the following dialog box:
Double click on any field in the table to modify it. Click on a field to select it. To delete an entry,
select it and hit the delete key.
If you make changes by editing, click anywhere in the table to make the changes
permanent.
You can import a new lookup table from a text file (extension .txt) or a DIF file created by a
spreadsheet program (extension .dif). A text table must have two columns, separated by spaces
or tabs.
The first line of the left column contains contains the unit of the measured quantity (RPM in our
example). The right column, first line must contain the word “Volt”.
In the succeeding lines contain the individual equivalents of the lookup table. Left column
contains the measured quantity and the right the equivalent voltage.
The slider on the left of the window shifts the entire table voltages up or down to
compensate for ground differences between the MTS device ground and the
