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.
∙ Once the engine is running, release SW1. SET SPEED should be displayed.
∙ Press and hold the switch until - SPEED is displayed to go into the speed setup menus, release SW1.
∙Now you can press and release the switch to scroll through the
Speed sensor setup (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” signal.
∙When “SENDER” is displayed press and hold SW1 until you get “ - ”
∙Release SW1 and the current sensor selection will be displayed
∙Press and release SW1 to toggle between “NORMAL” and “BUS”
∙When the desired setting is displayed press and hold SW1 until “ - ” “ DONE” is displayed
∙Release the switch to go onto the next sub menu item.
Auto Cal (AUTO)
This menu is used to calibrate the speed signal by driving a measured mile (or kilometer)
∙When “AUTO” is displayed press and hold SW1 until you get “ - ”
∙Release SW1 and the primary speed unit will be displayed
∙Press and release SW1 to toggle between “MPH” for miles per hour or “KMH” for kilometers 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” and the odometer should be reading “ 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.
