G-TECH / Pro Competition User Guide, Release 3.1

You will notice a few things about the graph screen:

•

The horsepower curve is drawn with a thick line; the 

torque curve is drawn with a thin line.

•

The peak horsepower and torque values are marked on 

the graph with vertical bars.

•

The peak horsepower and torque markers correspond 

to the values seen on the Horsepower/Torque sum-

mary screen (Figure 32).

•

The graph has moveable cursors for HP and TQ. The 

cursors move left and right using 

 and 

.

•

The HP cursor rides along the HP curve, and the TQ 

cursor rides along the TQ curve.

•

As the cursor moves, the “RPM,” “HP,” and “TQ” val-

ues are updated to reflect the current cursor position.

HP vs time

The “HP vs time” menu entry provides you with a graph of 

horsepower throughout the run.

This is not the optimal graph for analyzing horsepower. It will 

show artifacts around shiftpoints that are due to factors other 

than engine horsepower. The graph will also show the 

increasing effect of aerodynamic drag on the vehicle and the 

corresponding lower “net horsepower” as the speed 

increases.

To view the horsepower (HP) vs. time graph for a run, select 

the menu choice titled “HP vs time” and press 

:

You will see a graph such the one shown in Figure 34. Of 

course the shape of the curve, as well as the numbers and 

ranges, will be different for your vehicle.
