Add Map Segments - Closed Course Tracks Only
Now that we have created a GPS track map, the next step is to create track segments. In order
for the DataLink II software to provide segment data, it is necessary to break the track into
corners. Each corner will represent the start and end of a timing segment. However, in this
instance, we will use Lateral G forces to create the segments for us. By doing so, it automates
the process and eliminates the necessity of manually assigning segments.
Open the Add Map Segments Runlog page. Next, graph the Lateral G channel. Review the data
and determine the approximate Lateral G value obtained upon entry to most of the corners.
Next, determine the approximate Lateral G value upon exiting most corners. At high speed,
high lateral g force tracks, it is recommended to attempt to maintain at least .5 G difference
between the maximum and minimum values. Following this:
Step 1: Open Lap
To generate segments, it is necessary to open a lap. Use the same lap as previously selected to
generate the track map.
Step 2: Generate Segments
1. Insert the desire maximum Lateral G value in the Corner Start input box
2. Insert the desired minimum Lateral G value in the Corner End input box
3. Select the Generate Segments button.
Following this action, the DataLink II software will segment the GPS track map, and assign
names to each corner. Often times, a road course will assign a variety of names, to the same
corner. For example, the DataLink II software will assign a Turn 7 and Turn 8 to the track map.
However, the “official” name for the turn could be shown as Turn 7a and Turn 7b and Turn 7c.
In this case, the user may insert a variety of Lateral G values to create the approximate correct
number of turns. When creating circle track segments, the system will automatically create only
two turns. In order to divide the track into four corners, it will be necessary to manually edit the
segments, as reviewed in the following section.
Note: The factory default setting for Corner start is 1, while Corner End is .5. These
values are just a starting point and should be adjusted by the user, depending on the
cornering forces of the vehicle.
