Channel 80 - TrnRat Default Value 1.000
Channel 80 is used to enter the ratio of the transmission gear used during
the test. Channel 80 is used with Channel 79 and 81 to calculate the
overall gear ratio in Channel 55. Channel 80 is not required for any power
measurements. It is only used when calculating transmission slip.
Channel 81 - DrvRat Default Value 1.000
Channel 81 is used to input the drive ratio between the transmission
output and the rear wheel. Typical values are between 2 and 4. Channel
80 is used with Channel 79 and 81 to calculate the overall gear ratio in
Channel 55. Channel 81 is not required for any power measurements. It is
only used when calculating transmission slip.
Channel 82 - DJCorF Default Value 1.100
Channel 82 is used as an additional multiplier for creating SAEPwr
comparisons to uncalibrated dynamometers in your marketing area. The
factor is used in channel 114 to add 10% more power to Channel 112.
Numbers created using this factor are for speculation only, and
should not be used as a standard of any kind.
Channel 83 - Pul/Rv Default Value 0.500
Channel 83 is typically used to enter the number of spark pulses per
revolution for the engine RPM measurement. If the engine speed appears
to be off by a factor of two, change the number of pulses per revolution to
make the RPM read correctly. The engine frequency, Channel 11, is
combined with the pulses per revolution number in Channel 83 to make
the appropriate engine speed calculation in Channel 125. When using a
direct tach lead or optical tach sensor on channel 9, the value entered in
Channel 83 is used to obtain a correct factor for proper RPM calculation
in channel 125.
