Figure 40: Graph of Gs vs time
Some things to note about this graph:
• As with other graphs, you can use and to move
the cursor. The G-reading and timestamp always reflect
their respective readings at the current cursor position.
• Each tic mark on the horizontal axis marks 1 second
• Each tic mark on the vertical axis marks 0.1G of acceler-
ation
Figure 41 highlights some other useful information on the
graph.
Figure 41: Braking and accelerating
• When the G plot is above the horizontal axis, it means
the vehicle is accelerating.
• When the G plot is below the horizontal axis, it means
the vehicle is decelerating (e.g. coasting, braking).
• The brief dips you see in the graph are shift points.
When you shift, you temporarily remove power, and
this causes the vehicle to decelerate briefly, until you re-
engage the next gear.
• In a very powerful vehicle, or a traction-limited vehicle,
you may also spot dips in acceleration that are not due
to shifts.
