Figure 38 shows how to use this graph to analyze the time
spent in each gear and how long each shift took.

Figure 38: RPMs vs time — shifts and gears
You can determine how long a gear shift took by doing the
following:
• place the cursor at a peak RPM value for one gear and
make note of the time
• move the cursor to the right just until the RPMs begin
rising again and make note of the time
The difference between these times is the shift time. Your
vehicle actually slows a bit during shifts, so keep this time to a
minimum!
Speed vs time
The “Speed vs time” menu entry provides you with a graph
of speed throughout the run.
You can use this graph to measure things such as:
• time to get from one speed to another speed (e.g., 0-50
MPH, 40-60 MPH, etc.)
• time to accelerate from 0 to a certain speed, and brake
to 0 again (e.g., 0-100-0 test)
• time to brake to a halt from a particular speed (e.g., 60-
0 braking time)
To view the speed vs. time graph for a run, select the menu
choice titled “Speed vs time” and press
:
3rd gear
1st gear
End of shifts (clutch re-engaged, re-apply
throttle, RPMs rise again)
Start of shifts (clutch disengaged, let off
throttle, RPMs drop)
