CALIBRATION
The Digital Performance Speedometer leaves the factory with a factory pre-set industry
standard setting of 8,000 pulses per mile. You should not have to recalibrate your
speedometer, unless you have changed the original tire size or the rear end gear ratio.
Also, if using the Intellitronix GPS Sending Unit, (S9021 – not included) the speedometer does
not need to be calibrated.
NOTE: DO NOT attempt to recalibrate your speedometer until after it is working properly, and
you have determined that the speed is consistently incorrect. The calibration procedure will
NOT correct a faulty installation or improper wiring.
WARNING: If, while in 'CAL' mode, you do not move the vehicle but press the button
again, the microprocessor will NOT have received any data and the unit will display
'Err' and will revert to the factory settings. At a minimum, drive some distance and return
to the start if necessary. If you miss stopping the display at' CAL', simply repeat the steps.
To calibrate:
1. Locate a measured mile or KPM 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 pushbutton 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 trip, the speedometer should read something other than 0 MPH. If it does
not change, return and locate the problem before continuing. Otherwise, proceed
with the calibration.
2. Stop at the beginning of the measured mile with your vehicle running and in
odometer mode (NOT trip mode), press and hold the push-button until the odometer
displays 'HI- SP'. On its own, the gauge will then cycle through the recorded
performance in the following order: '0 – 60', '1/4', 'ODO', and 'CAL'.
3. While 'CAL' is displayed, quickly tap the push-button once. This will put the
speedometer in Program Mode. If you did not tap while 'CAL' is displayed, the pulses
per mile will be displayed on the odometer and the display will go back to MPH mode.
Otherwise, you will now see 'CAL' displayed along with the number '0'. This
indicates that the microprocessor is now ready for calibration.
4. When you are ready, begin driving on the metered mile. You will notice that the reading
will start counting up. The odometer will begin to display the incoming pulse count. Drive
the vehicle through the measured mile (speed is not important, only the distance
traveled).
5. At the end of the mile, stop and press the push-button again. The odometer will now display
the new number of speedometer pulses that were registered over the distance. The
odometer will continue to display the pulse reading for a few seconds. Once it reverts to
the default mode, you have successfully calibrated your speedometer.
