KOSO DB01 UK PROGRAMMING INSTRUCTIONS
Please read all the way through before starting this procedure
The DB01r is a compact digital gauge with the following functions: Speed (Mph & Kmh), RPM, Fuel Gauge (100ohm, 510 ohm), and 4 warning lights.
Before you start to program please connect the wiring for the gauge as per the manufacturer’s instructions and measure the circumference of the tyre (this is very important) a quick reference wiring guide can be found towards the end of these instructions.
To Enter Menu
Press and hold down both buttons for 3 seconds this is the standard procedure for all settings and you must scroll through the menu every time. If left for more that 30 seconds the screen resets.
MPH or KMH Screen
Press the adjust button once to set the speed setting for MPH or KH
Press select button (this moves you through the setting screens)
You will need the circumference of the tyre at this point please enter your size in millimetres by entering one digit at a time in the flashing position on the gauge screen
For instance if you size is 1800 millimetres, the first flashing light press the adjust button until it displays 1 – after that is set press the select button to move to the next flashing position in the display press adjust button until it reads 8 - after that is set press the select button to move to the next flashing position in the display press adjust button until it reads 0- after that is set press the select button to move to the next flashing position in the display press adjust button until it reads 0. Press select once.
This is where we set up the number of magnets, or if you are using the cable drive converter * the sensor points.
Now you have set the tyre circumference the screen will flash 1P using the adjust button set for the number of magnets (previously fitted to the wheel) any number between 1 – 60.
*Cable drive converter – if you are using the cable drive converter instead of magnets use the following system to determine. the number of sensor points – rotate the wheel once noting how many times your standard cable turns per single rotaion of the wheel for instance 2.5 turns per single rotation....
Every time the standard cable turns its equivalent to six sensor points (magnets) therefore in the instance of the standard cable turning 2.5 times per rotation of the wheel it will be 2.5 x 6 = 15 sensor points (magnets)
Once set press the select button to move on to the next menu position.
Setting the RPM Counter
Once you have determined which position on your vehicle this is to be taken from (see manufacturer’s instructions) you need to tell the gauge the type of engine you are reading the signal from there are three settings to make. Incidentally I get the best results from the negative side of the coil.
Setting One 2 stroke or 4 stroke
Using the adjust button as before set for 2c (2 stroke engine) or 4c (4 stroke engine)
Setting Two The number of pistons.
Before we attempt this procedure, see the examples below which I hope will help you understand this setting a little better.
Coil Connection this is just an example if in doubt try other settings
Engine has 6 pistons and 3 coils set the number of pistons to two
Engine has 4 pistons and 2 coils set the number of pistons to two
Engine has 4 pistons 4 coils set the number of pistons to one
Engine has 2 pistons 2 coils set the number of pistons to one
Engine has 2 pistons one coil set the number of pistons to two
Induction where you wrap around the HT lead do it about 20 times and cover it tightly with tape to hold it in place
In this instance you are only reading the pulses from one of the cylinders therefore on most occasions you will set it for one piston.
Setting Three The Hi Lo setting
If you connect to the negative side of the coil set it to LO
If you connect it to the positive side of the coil set it to HI
Once you have set the RPM gauge press the select button to move onto the next menu setting.
Setting the Fuel Sender Range
Most senders are covered by the following ranges the most important setting is that it reads empty when it is empty. Please connect this wire to the negative side of the fuel sender it is my experience that because the sender is negative switched it will not work from the existing gauge wires.
Using the adjust button select the 100 ohm or 510 ohm range as a general rule of thumb only Honda use the 510 ohm range.
RED +12 volt switched live
Black -12 volt earth/ ground
White -12 volt Neutral lamp (usually switched negative)
Green - 12 volt to negative wire of fuel sender 100 or 510 ohm
Brown RPM wire see instructions for fitting options
Orange +12 volt Left Turn signal /indicator
Yellow Fuel Gauge
Blue + 12 volt Right turn signal / indicator
Gray Oil pressure lamp.
Black white plug Speed sensor
NOTES - Please note sometimes when replacing the bulb in a circuit the LEDs used in this gauge do not have enough resistance to trigger the flasher unit , if this is the case add a ¼ watt 250ohm resistor in parallel (to black earth wire) to the Left and Right indicator wires or fit a flasher unit suitable for LED Indicators.
