Channel 89 - RWD
Default Value 1
Used only on AWD systems
Channel 89 is used to select whether the rear rollset power calculations
are to be used on the AWD system. A zero in this channel disables the
rear rollset power calculations in the final wheel power calculation. This
channel is not used on the 2WD or
AD-11
systems. See Table 9-2: for
the various modes available on the AWD system.
Channel 90 - IntFw
Default Value 0
Used only on AWD systems
Channel 90 is used in channel 39 to add an approximate front wheel
assembly inertia to the inertia power calculation for the front wheels on
AWD systems. The value is equivalent rotating mass in pounds. It is
recommended to use the default value unless you have a more accurate
number from the vehicle manufacturer or have an accurate way to
measure the rolling inertia of the front wheel assembly. Leaving the value
at zero will allow the inertia power channel to calculate the actual power
imparted to the roll, without being influenced by the front wheel assembly
inertia. In this mode, tests run at varying rates of acceleration will produce
slightly different power results. If you do apply an accurate front wheel
assembly inertia value, then the inertia power numbers will generally
match regardless of the rate of acceleration. This number is not used on
2WD systems or when running only 2 wheels on an AWD system.
Channel 91 - IntRw
Default Value 0
Channel 91 is used in channel 43 to add an approximate rear wheel
assembly inertia to the inertia power calculation for the rear wheels on all
systems. The value is equivalent rotating mass in pounds. It is
recommended to use the default value unless you have a more accurate
number from the vehicle manufacturer or have an accurate way to
measure the rolling inertia of the rear wheel assembly. Leaving the value
at zero will allow the inertia power channel to calculate the actual power
imparted to the roll, without being influenced by the rear wheel assembly
inertia. In this mode, tests run at varying rates of acceleration will produce
slightly different power results. If you do apply an accurate rear wheel
assembly inertia value, then the inertia power numbers will generally
match regardless of the rate of acceleration.
Channel 93 - Recpcl
Default Value 1.000
Channel 93 is a reciprocal value used by the Pro Filter feature to properly
calculate engine speed increments when using the optical tach or
calculated RPM methods. This value is controlled and computed by the
acceleration test profiles. It should not be altered by the user.
Channel 94 - RpmRat
Default Value 1.000
Channel 94 is the ratio used by channel 125 for calculating engine speed
when using the optical tach or calculated engine speed methods. This
ratio is computed automatically when the
EngSpd
test profile is run to
select the engine speed method. Unless the exact ratio is known, it is
recommended to run the
EngSpd
test profile and allow the system to set
this ratio.
