ACE-6XXX User Manual

RPM sensor mounting:

Reed Speed Sensor and Magnet:

1. This sensor is universal sensor for motorcycle, find a rotating part to

     install magnet (for example disk, sprocket or driveshaft) and a location 

     to install the sensor where it can be aligned to the magnet.

2. Align the center of the magnet to either of the sensor marking lines or 

     the side of the sensor. The magnet must not travel down the body of 

     the sensor.

3. Installing the sensor parallel to the vibration direction creates optional 

    anti-vibration effect. 

4. Make sure the gap between the magnet and the sensor is within 8mm.

Speed Sensor Mounting:

ACEWELL has several speed sensors; the unit may include one of them. 

If the model is intended to be connected to a gearbox electronic speed 

output to obtain the speed reading, no speed sensor will be included.  

FUNCTIONS

RPM: Digital Tachometer

1. It displays digital tachometer up to 19,990RPM and displays 19,999

    rpm when tachometer is over 20,000rpm..

2. It has 2 wires to pick up RPM signal, the yellow wire is to connect to 
    Plug,and white wire is for signal from ECU or Ignition coil.

Shift Warning RPM

1. The function enables you to set up a shift warning RPM.
2. A indicator flashes when RPM reaches 500rpm before setting value.
3. Shift warning LED indicator flashes when RPM reaches setting value, and stops
    flashing after you shift gear.

Km/H or MPH: Speedometer

1. Displays speed mete r up to 399.9 Km/H or 248.5 MPH.    

2. The maximum frequency of software divider is 7K Hz.

3. With a small wheel size and large number of pulses per wheel 

     revolution it may not be possible to display very high speeds. 

MAX: Maximum Speed Meter

 

Displays highest speed achieved since last Reset operation

AVG: Average Speed Meter

It calculates average speed from last RESET. The AVG is calculated from 

TRIP1 be divided by RT.

TRIP 1&2: Trip Meter 1&2

TRIP function accumulates trip distance since last RESET as long as bike/

vehicle is moving.

Specific Hall sensors:

Cable drive adaptors for most bikes originally fitted with cable driven 

speedometers or odometers  are available. When using these cables it 

is necessary to divide the circumference setting by the number of 

rotations of the cable per rotation of the wheel.

Thermo Sensor and Sensor Tube:

1. The unit includes a water temperature sensor; you may  have to 

     purchase a suitable water pipe temperature sensor tube to install 

     the sensor on some bikes.  

2. Cut the water pipe, insert the temperature tube into the pipe and

    secure it by attached pipe clamps.

3. Screw the sensor into the tube.  

4. If your vehicle is fitted with a thermostat that stops water flowing to 

    the radiator when the engine is cold, you will not get a reading until 

    the thermostat opens.

5.Custom sensors are available for carburetted bikes to replace the 

   original  sensor. 

Wire Remote Control Switch Installation: 

1. Install the switch arm on handlebar. 

2. Install the switch box to one of 3 fixing holes and adjust switch box to 

     a suitable angle. 

3. Plug the switch box connector into the main unit matching connector.

Hall Effective Speed Sensor and Magnet: 

1. This is universal sensor for ATV or motorcyclefront or rear wheel

     installation or motorcycle front wheel installation. For some fitments 

     an accessory speed sensor holder may need to be purchased.

2. Find a rotating part to install magnet (for example disk, sprocket or 

    driveshaft) and a location to install the sensor where it can be aligned 

    to the magnet 

3. Align the center of the magnet to center of side face of the sensor. 

4. Make sure the gap between the magnet and the sensor is within 5mm.

1.Connect either the yellow or gray wire to sense the  RPM signal.

2.The yellow wire can be wrapped around the spark plug lead.

   a.Signal strength from the ignition coil is dependent on coil type.

   b.Coil 2-5 turns around spark plug lead, the more turns the stronger the signal. A 

       weak signal will not show a reading on the screen whereas a very strong signal 

       will have a reading which is too high or very jittery. If the reading is incorrect 

       then try putting the 1MΩresistor which is included in the box inline in the 

       sensor wire.

3.If the signal is still unstable, please try to connect the gray wire to either the 

   ECU rev counter output or to the primary side of the coil or to the pulse wire on 

   an active spark plug cap.

Digital Voltage and Battery Warnings

 

1. It checks bike’s battery and charging systems health. 
2. It has 3 modes to be set, b-on, b-oFF and b-HI, all 3 modes range is from 11.0V to 15.0V. 
3. The “b-on” means battery warning on voltage, when the voltage falls below this the 
     LED will flash.
4. The “b-off” means battery warning off voltage, b-off voltage must larger than b-on  
     voltage.
5. The “b-HI” means battery high voltage, it comes on to warn that the batter has over 
     charging. 

          : 

Gear Indicator

1. The gear indicator calculates gear by comparing speed and RPM then displays gear 
     position. 
2. User has to train the gear indicator before use it.

SCAN: Scan function

1.The 2nd row of LCD data will be changed automatically every preset number of 
   seconds if the SCAN is selected. The scan period is from 1 to 20 seconds. 
2. All functions will be manual operations when SCAN is switched off. 

          

: Fuel Gauge 

 

1. Has 7 bars to indicate how much fuel remains.

2. To use as a fuel gauge, the user enters the sender ‘empty’ resistance between 10 

    and 990 ohms and the sender ‘full’ resistance between 10 and 990 ohms. The 

    computer produces a linear scale of bars between these two resistances. When less 

    than 10% fuel remains the gauge will flash and the warning LED if fitted will light.

3. To use as a reserve indicator, connect the reserve switch to the input and put into 

    “rEs” mode. When the switch pulls the input to –ve the LED warning will light. On 

     vehicles with temperature based sensors a 68Ω 5W resistor needs to be connected 

     between the input wire and 12v (switched).

4. If the gauge and warning lamp are not required they can be switched off

         

Bar Thermometer*

1.Have 7 bars to indicate engine temperature. 

2.The 4th bar counts from bottom be turned on and over temperature LED flashes when 

   thermometer reaches the preset warning temperature, each +/-15

˚C

 lights on/off a bar 

   base on the 4th bar.

3.The bar-temperature flashes when the measured temperature is higher than the preset  

   warning temperature.

LAP: 

Lap Timer

1.It can keep up to 99 sets of lap timer of each circle. 

2.The function must be operated by an additional wiring remote control

    switch or an accessory IR receiver/transmitter or a magnetic field sensor. 

Freezing Time for Lap timer:

1.The freezing time is designed to avoid additional count signal during the set time. 

2.The set range is from 1 to 20 seconds.
