8.7.5.3 In_Dec_A.tpf
The Inertia Deceleration test is exactly like the Mph_Rpm inertia test but it offers the operator the
option of collecting data during coastdown on subsequent runs after the first acceleration run. The
coastdown data collection termination point is determined by MPH.
Data is collected at 100 times per second during this test, to allow greater analysis of coastdown
data. Data is automatically saved at the end of each test run to a SFD file on the computer disk
drive.
8.7.5.4 Decel_A.tpf
This Deceleration test allows the operator to accelerate to a selected speed in MPH and then
disengage the clutch or shift the vehicle into neutral to process vehicle coastdown parasitic loss
data. This data is available in channel 127, CsDnLs, loss in horsepower. The value will be a
negative value, but represents the amount of parasitic loss power in the drivetrain of the vehicle.
Data is collected at a rate of 10 times per seconds and is automatically saved at the end of each
test run to an .sfd file on the computer disk drive.
8.7.5.5 Eng_Spd.tpf
The Engine Speed test provides a convenient method for setting up the engine speed pickup on
the vehicle you are testing. It prompts the operator through several optional engine speed
methods, and provides input screens for selecting and configuring each RPM method. Although
this can be done via the specifications editor function within WinDyn, this test profile may speed up
that process and can be done while on or in the vehicle.
At the end of the test, be sure to save the new settings to a specification file for the vehicle under
test. Simply load the specifications file the next time that vehicle is tested, foregoing the lengthy
RPM setup process.
8.7.5.6 RpmRamp.tpf
This test is only available on eddy current equipped dynamometers.
This test allows the operator to perform a ramp test using engine speed parameters instead of
MPH. At the beginning of the test, the system compares roll speed to engine speed and calculates
a ratio between the two. Once that ratio is known, the test prompts the user for lower and upper
engine speed (RPM) setpoints and requests a ramp time. From that point forward, the test
functions just like the controlled acceleration test profile, collecting data every 0.1 seconds. Data is
automatically saved after each ramp.
