Once the instrument is mounted and wired into the vehicle (see preceding page), the instrument should be tested to verify that the electrical con-
nections are working properly. First, watch the instrument’s display as power is applied with the key in the accessory position. The speed display
will show “888” and the tach display will show “8888”. Then the tach display will show “000”, the speed display will show “0”, and the odometer
will show the current miles. This action verifies that power is properly connected to the instrument. Start engine. The Tach display will show the idle
RPM. The vehicle should be driven some distance to verify the Vehicle’s Speed Sender (VSS) is connected properly and that the display indicates
speed. If the display does not indicate speed, verify that the VSS is connected properly and that calibration has been performed.
Testing
Calibration
(Electronic Speedometer calibration made easy!)
To calibrate your electronic speedometer:
1) With the power off, push and hold the trip button. While holding the button, start the vehicle and continue to hold the button until the display shows “PrE”.
You may now release the button.
2) Drive to the beginning of a pre-marked 2 mile (2 km if in km/h mode) distance and come to a stop. It does not matter how far away it is to get to this pre-marked 2 mile
distance. DO NOT SHUT THE ENGINE OFF. Push and release the trip button. The display will show “rdy”.
3) Drive the 2 mile distance. The display will show “CAL” no matter what speed you drive. It will be normal to see the LCD display counting rapidly as it is receiving a
speed signal. If you have to stop during the calibration, that is o.k. The speedometer will simply stop counting pulses during this time.
4) At the end of the 2 mile distance, come to a complete stop and push and release the trip button. The display will show “End”, the odometer will show the calibrated PPM.
and the calibration is stored. Then the display will show “0” and the odometer will show miles. You are now finished.
Remember the accuracy of your 2 mile distance will directly affect the accuracy of your speedometer.
The following list contains factors that can affect speedometer accuracy and how to minimize them during calibration.
1. Tire diameter increases slightly as vehicle speed increases. To minimize this error drive at an average speed of 45 MPH (175 KPH) during calibration.
2. Tire diameter increases slightly as tire air pressure increases. To minimize this error, check the vehicle’s tires to ensure correct air pressure.
3. Tire diameter changes with vehicle load. Minimize this error by having an average load in the vehicle during calibration.
4. Minimize tire slippage error by not breaking traction during calibration.
Note: Always recalibrate your speedometer after any tire size or differential ratio change.
The MODE button allows the user to select between MPH and km/h (kilometers per hour) at any time, even while the vehicle is in motion. When
in MPH mode, the arrow on the lower left side of the LCD odometer will be on. When in km/h mode, the arrow on the lower right side of the LCD
odometer will be on. Changing modes will change the speed on the LCD display, as well as the accumulated odometer and trip values. It is
important to note that this affects field calibration. If in MPH mode, field calibration is done by driving two miles. If in km/h mode, field calibration
is done by driving two kilometers.
mODE
When power is first applied to the gauge, the tach display will show “8888” and the speed display will show “888”. Then it enters normal
operation mode, the speed display will show “0” and the odometer will display the odometer or trip miles, depending on the state of the odometer
(total miles or trip) when it was last turned off. The tach display will show “000” if the engine is off, or the idle RPM if the engine is running.
Operation
Configuration
The tachometer is configured at the factory for 4 PPR. (8 CYL)
To change the PPR, follow the steps below:
3. The display will change every 1.25 seconds to 1.0, then 1.5, 2.0, 2.5,
3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, and back to 0.5. See the table below
to find the display reading that corresponds to the desired PPR.
4. When the display indicates the desired PPR, press and hold
the TRIP button for 1 second, then release. This will
permanently store the settings and exit Configuration mode.
1. With no power applied to the tach, press and hold the TRIP button.

2. While holding the TRIP button, apply power to the tach by turning the
ignition switch to the “Accessory” or “On” position. Do not start the
engine! Release the TRIP button immediately after power is applied.
The display will show 0.5.
