4x4 Low Range Detection
Low range detection can be enabled if you want the controller to switch to an
alternate calibration table when 4x4 low range is engaged. Configure the
options in Shiftware under the “2WD/4WD Options” and “Table Select” tabs in
the settings window. For example, 4x4 low range detection can be enabled so
that when ground is applied to pin 5 (purple) of the vehicle harness, the
controller will switch to table 2. Another option includes single-clicking the
controller knob to enable 4x4 low range calibration. Up to 3 low range ratios can
be used. When low range is engaged, “LO”, “L2”, or “L3” will display beside
speed on the built-in display. (Firmware 6.0d or higher required.)
Speedometer Output
We have provided an adjustable speed signal output on the tan wire on pin 12 of
the vehicle connector that can be used to drive an electronic speedometer. Use
of this output signal is not necessary, but it can be helpful if your speedometer
can not be driven correctly from another source. This signal can also be
corrected for different gear ratios and tire heights, so it can be very useful in
some applications. The speedometer output signal is provided as a 12 Volt
square wave or 5 Volt AC signal. The speedometer output modes can be
selected via the built-in tuning interface in Setup Menu>SpeedoOut or in the
tuning software. After entering the SpeedoOut menu, the current mode and ratio
will be displayed. Push the knob to configure speedo out options. You can
choose between 5V AC, 12V Pulse, Disable, Replicated, Adjustable, and Reset
SPO. After making your choice, you can then fine tune the speedometer ratio
using the knob. Choosing replicated will provide an amplified and squared
replica of the speed sensor signal on the speedometer output. Reset SPO will
clear all saved data for the speedometer output and revert to using values from
the tune.
The speedometer output is adjustable and is essentially the electronic
equivalent of a ratio corrector gear box for a mechanical speedometer. When
adjusting the speedometer output, the correction factor is entered as a decimal
number. The correction factor is the frequency ratio of the speedometer output
frequency to the speed sensor frequency. This number can be easily adjusted to
synchronize the vehicle speedometer to a GPS or other instrument. If you have
a 4WD transfer case with low range capability and want the speedometer to be
accurate while in low range, you will need to adjust the speedometer ratio in
both high and low range in Shiftware and save a tune for high range and a tune
for low range or multiple low ranges. ResetSPO will allow you to use the tune
values.
