Calibration - Intellitronix B-9999 Installation Manual

If replacing a cable: screw the provided sender onto the 7/8" male fitting you located previously
for the existing electronic sender. If a two-wire sender, you should hook one of the two wires to the
speedometer signal wire on the speedometer and the other wire to the ground.
If you have a three-wire sender, you will need to contact your vehicle manufacturer to ask exactly
which wire is the signal wire, as the wire colors can vary between manufacturers.
Speedometer
In order to isolate the signal wire from electrical noise, we recommend that you use a shielded
cable to connect the speedometer to the sender. Be sure to run the cable as far away as possible
from the ignition system and any power wires to electric fuel pumps, motors, blowers, etc.,
particularly spark plug wires. For best results, we also recommend the use of resistor-type spark
plugs and spark plug wires that are in good condition.
Note: If using the Intellitronix GPS Sending Unit (not included), the speedometer does not need to be
calibrated.
The speedometer leaves the factory with a pre-set industry standard setting of 8,000 pulses per
mile. Chances are that you may not need to recalibrate your speedometer, unless you have
changed the original tire size or the rear end gear ratio.
Note: Do not attempt to recalibrate your speedometer until after it is working properly and you have
determined that the speed is incorrect. The calibration procedure will NOT correct a faulty installation or
improper wiring. If you attempt to recalibrate your speedometer without making sure the speedometer is
receiving pulses from the sending unit, the speedometer will display 'Err' and default back to the factory
settings.
To calibrate:
1. Locate a measured mile where you can safely start and stop your vehicle. By
running the vehicle over this measured distance, the speedometer will learn the number
of pulses outputted by the speedometer sensor during a specific measured distance. It
will then use this acquired data to calibrate itself for accurate reading. There is a small
recall push-button in the center of the panel used to calibrate and read all of
the data stored in the speedometer. After installing your speedometer according to the
wiring instructions, when the ignition is on it should immediately display the default
screen of 0 MPH, if the vehicle is not moving.
NOTE: You will then need to drive your vehicle to the predetermined measured mile. During this
