  • Account round

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

    Example CB650 from 1979:

    If it does not work this way (as on the BMW K100 for example), it must be installed as follows:

  • Odometer

  • The probe must be installed on a support (the stirrup for example) and the magnet(s) installed 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 the connections between the permanent + and the + after ignition.


    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? Calculate the perimeter of the wheel.

      Calculation of the perimeter of a circle:

      P = 2x x Radius (in mm)

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

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

      Once calculated, you can fill in 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 save, then enter setting area 2.

      2. The number of cylinder

      In the second level of adjustment.

      It is indicated: "y2".

      2 means the number of engine cylinders is 2.

      3 corresponds to 3 cylinders

      4 is 4 cylinders...

      Press the key to set the number of cylinders.

      Hold the button for 3 seconds to save.


      3. Fuel gauge adjustment

      It is indicated on the right the value 1 or 5.

      1: indicates using 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 don't 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 30-500 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). (about 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. Accumulation of speed

      The basic position is "F03.4"

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

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