Theory Of Testing

Since the system is actually controlling to a factored MPH based on the ratio calculated at the
beginning of the test, the actual RPM setpoints may deviate by a small percentage. However,
small setpoint adjustments by the operator should allow for compensation of any error.
This test is useful for fuel injection mapping at steady throttle positions at incremented RPM points.
8.7.5.7 Steadyst.tpf
This test is only available on eddy current equipped dynamometers.
This RPM Steady State test allows the operator to perform a steady state 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 operator is prompted
for a steady state RPM to control to and a length of time to do so.
The test proceeds to control the vehicle to the desired engine speed (+/-100 rpm) for the desired
time. Since the system is actually controlling to a factored MPH based on the ratio calculated at
the beginning of the test, the actual RPM setpoint may deviate by a small percentage. However,
small setpoint adjustments by the operator should allow for compensation of any error.
This test is useful for fuel injection mapping at a steady RPM for various throttle position settings.
Data is recorded every 0.1 seconds and is saved at the end of each RPM point iteration.
