SPEEDOMETER SETUP/CALIBRATION
There are two main methods for calibrating the speedometer, auto cal and adjust. Auto
cal requires that you have one measured mile marked out (1 km for metric). Adjust requires you
to follow another vehicle going at a set speed, using a handheld GPS with speedometer
function, or timing yourself over a mile to determine your speed.
* Dakota Digital recommends you start with the Auto Cal method to get the speedometer
close. If you find it’s reading too fast/slow after the Auto Cal, then attempt the Adjust
mode.
• Press and hold SW1, then turn the key on and start the engine.

Speed sensor setup (SENDER
SENDERSENDER
SENDER)
This menu is used to set the speed sensor input type. You can use the supplied pulse
generator or existing speed sensor for most applications. You can also read the speed signal
with the use of a future product called the bus interface module (BIM). Dakota Digital also offers
BIM that will allow you to read the speed signal from an ECU if you are installing the system in a
vehicle equipped with the OBDII port or a drivetrain from a newer vehicle, most 1996 and newer
vehicles have this.
If you are using a Dakota Digital pulse generator or feeding an ECU signal into the SPD
SND terminal, this is considered a “normal

per hour. The setting saved here will be what the speedometer reads as well as the
units used to calculate odometer mileage.
• When the desired unit is displayed press and hold SW1 until you see the “ - ” then release
SW1.
The speedometer will display “CAL

CAL” and the odometer should be reading “000000
000000000000
000000”, the
other displays should be lit and display normally(fuel, volt, water, and oil). Begin driving the
measured mile. The odometer reading should start incrementing as you travel, indicating the
pulses received from the speed sensor or VSS. This is known as the pulses per mile (PPM).
Once you reach the end of the marked mile, or are passing the marker, press and release SW1.
The displays will flash off, then everything should light up and the speedometer should now be
displaying your speed. Auto Cal is now complete and your speedometer should be reading
correctly.
