Track map creation troubleshooting
In this paragraph it will be described the possible solutions to the mostly common
map creation troubles encountered.
1. If it appears the following window
please select a “Good lap, labelled as “Lap marker” in the Lap cause
column of the Lap manager dialog box, and deselect the previously used
lap (by double clicking on the lap number).
2. Select a lap without many skids.
3. Verify that it is set the correct vehicle type (2 or 4 wheels) in the “Modify
track map” window.
4. Verify that the values stored in both speed channel and lateral
acceleration one are sensible: lateral acceleration has to be near to 0 in
the straight line, while speed must be greater than 0 and must not have
high or low peaks.
5. If lateral acceleration, or the gyroscope signal, in the straight line is not
quite near to 0, it is probable that the lateral accelerometer, or gyroscope,
has not been autocalibrated. It is possible to solve this problem by
summing or subtracting a fixed value (see “Measure Information” dialog
box) in order to have 0 in the straight line. Please, before starting a new
test run, remember to calibrate the internal lateral accelerometer.
