Building a Trackmap
Building a trackmap following download of the first run is of utmost importance. All of the timing
functions (lap and segment) along with data reports are based on the trackmap. If no trackmap is created,
then it is impossible to open laps, overlay and compare data. In a typical inertia and wheelspeed based
data system, the rollout of the tire, combined with wheel rpm provides an approximate distance value, in
order to compute data. Keep in mind this is a GPS based data system. As such, no wheelspeed sensors
are in use, so it is mandatory to build a trackmap in order to obtain distance values. Complete
instructions concerning the building of a trackmap can be found in the G2X Manual. In addition, a demo
run is available in the DatalinkII software, along with instructions for use, in the back of the G2X
Manual. Use the demo run to practice building a trackmap, before going to the track. If a trackmap is not
created following the first run, and subsequent runs are downloaded without a trackmap, the user will
then be forced to manually insert a trackmap in all runs that have previously been saved to the users PC.
Trackmap Tips
1.
At least two completes laps on the track are required, before the software
can construct a trackmap.
2.
In or out laps are not considered a complete lap.
3.
If inside and outside lines are desired, those laps can be made during a run
or at any other time.
Segmenting a Trackmap
Track segmenting is necessary in order to produce all of the segment related reports available in the
DatalinkII software. Segments are created by the use of lateral g data. The start of a corner marker is
defined by the Corner Start number as found in Step 2 of the Add Map Segments Runlog page. The end
of a corner is defined by the Corner End number entered in Step 2 of the Add Map Segments Runlog
page. Complete instructions concerning the segmenting of a trackmap can be found in the G2X manual.
In addition, a demo run is available in the DatalinkII software, along with the instructions for use found
in the back of the G2X Manual. Use the demo run to practice building segmenting trackmap, before
going to the track.
Trackmap Segment Tips
1.
Default Corner Start and Corner End numbers are entered by the
DatalinkII software. These numbers may be changed according to the
needs of the user.
2.
Segments are created from one lap (as used to create the trackmap) and
are not affected by future downloaded data.
3.
Consider the segments markers as GPS plotted points on a virtual
trackmap. Once the trackmap and segments are created and saved, the user
will have that map for use, forever.
4.
If a trackmap is not in view when the Add Map Segment page is open
(after a trackmap is created) a complete lap was not used to create the
trackmap. Create another trackmap, using a different lap.
