DIGITAL METER INSTALLATION

1. Connecting the wires

Model V1:

There are 4 connectors.

On the 9 terminal connector, the correspondence is as follows:
light blue: right indicator
orange: left indicator
dark blue: full beam/high beam
white and brown: crossing/night light
yellow and black: rev counter
green: negative/ground
black: positive after contact
red: permanent positive
blue and white: fuel gauge.

On the 6 terminal connector, the correspondence is as follows:
green and red: neutral
pink: 1
blue/red: 2
green/black: 3
yellow/red: 4
yellow/white: 5

On the 1 terminal connector, the correspondence is as follows:

green/white: 6

On the 3 terminal connector, the correspondence is as follows:

Model V2:

9-pin connector:
light blue: right indicator
orange: left indicator 
black: positive after contact 
blue and white: fuel gauge. 
purple and black: rev counter 
brown: crossover/night light 
red: permanent positive 
green: negative/ground 
dark blue: full beam/high beam

3-pin connector:
White: + speed sensor
Green: - speed sensor
Black and White: speed sensor signal

1 terminal connector:
Green and Red: 6

2.Installation

Account round

The rev counter (black and yellow wire) is to be installed at the negative output of the coil.

Example CB650 from 1979:

If it doesn't work this way (like on the BMW K100 for example),It must be installed as follows:

You must install the probe on a support (the caliper for example) and install the magnet(s) on the disc. It is preferable to install the magnets as close as possible to the sensor (+/- 2 mm).

3. Settings

Go to menu

To reach the settings menu, you must lock the button for 3 to 5 seconds then switch on the ignition.

Try longer if unsuccessful.

If the problem persists, check the assembly and connections between the permanent + and the + after contact.

The menus 

There are 4 menus. The speed display tells you what level you are in.

Menu videos:

1. Circumference adjustment:

In the first level of adjustment.

the mileage shows “CCC---”. 

XXX means the default wheel circumference.

How to define the circumference? You need to calculate the perimeter of the wheel.

Calculating the perimeter of a circle:

P = 2x x Radius (in mm)

Radius = Axle of the wheel at the end of the tire.

Note: If during the test the meter has an error of 5 to 10%, add 5% (P*1.05) to this result.

Once calculated, you can enter the data.

The thousands number will flash at this time, short press to change the current number.

After a few seconds, the device automatically switches to the hundreds setting, then the tens setting.

Its range is 50~2600mm.

Hold the button for 3 seconds to record, then enter setting area 2.

2. The number of cylinders

In the second level of adjustment.

It says: "y2".

2 means that the number of engine cylinders is 2.

3 corresponds to 3 cylinders

4 corresponds to 4 cylinders...

Pressing the key allows you to adjust the number of cylinders.

Hold the button for 3 seconds to record.

3. Fuel gauge adjustment

The value 1 or 5 is indicated on the right.

1: indicates the use of a 2-wire sensor.

5: indicates the use of a 3-wire sensor.

Hold the button for 3 seconds to save, then enter the allowable mileage setting area.

To be chosen according to the resistance model of your motorcycle.

If you do not have a fuel gauge sensor, grounding the fuel gauge wire (blue and white) will cause the fuel gauge to stop flashing.

For others, you need to ground it through a 30 to 500 ohm resistor.

Anything more or less common has no effect. 500 ohms displays 1 bar (out of 8) or almost empty. 30 ohm 8 bar display (full screen). (around 330 ohms is half full, etc.) So if grounding the fuel wire doesn't work for you, try grounding it through a resistor between 30 and 500 ohms.

Fuel gauge sensor (example: Royal Enfield):

4. Speed ​​accumulation

The basic position is "F03.4"

F = the frequency, which is used to change the speed

Once the counter setting is finished, long press the button to save and exit the menu.
