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. Adjust requires you to follow another
vehicle going at a set speed, use a handheld GPS with speedometer function, or time 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

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 bus interface module (BIM). Dakota Digital offers a 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
