INSTALLATION & PARTS
Main Unit Installation
![Acewell - CA-085-15X - Main Unit Installation Main Unit Installation]()
RPM sensor mounting
![Acewell - CA-085-15X - RPM sensor mounting RPM sensor mounting]()
- Connect either the yellow or white wire to sense the RPM signal.
- The yellow wire can be wrapped around the spark plug lead.
- Signal strength from the ignition coil is dependent on coil type.
- 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 1MΩ resistor which is included in the box inline in the sensor wire.
- If the signal is still unstable, please try to connect the white 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.
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.
Reed Speed Sensor and Magnet
![Acewell - CA-085-15X - Reed Speed Sensor and Magnet Reed Speed Sensor and Magnet]()
- 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.
- 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
- Installing the sensor parallel to the vibration direction creates optional anti-vibration effect.
- Make sure the gap between the magnet and the sensor is within 8mm.
Hall Effective Speed Sensor and Magnet
- This is universal sensor for ATV or motorcycle front or rear wheel installation or motorcycle front wheel installation. For some fitments an accessory speed sensor holder may need to be purchased.
- 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
- Align the center of the magnet to center of side face of the sensor.
- Make sure the gap between the magnet and the sensor is within 5mm.
![Acewell - CA-085-15X - Hall Effective Speed Sensor and Magnet Hall Effective Speed Sensor and Magnet]()
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
- 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.
- Cut the water pipe, insert the temperature tube into the pipe and secure it by attached pipe clamps.
- Screw the sensor into the tube.
- 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.
- Custom sensors are available for carburetted bikes to replace the original sensor.

- These values are approximate and will differ for different brands of tyre, we would always recommend that you measure the distance travelled per revolution of the wheel in mm and enter this into the computer.
- The computer calculates the wheel rotating length between 2 passes of the magnet; use this table to find the settings when you are using a reed sensor or an universal hall sensor with magnet to measure your speed.
- If you are using a cable drive speed sensor then enter the number of turns of the cable per turn of the wheel into the pulses screen.
- You can use more magnets, enter the number of magnets fitted into the pulses screen.
- If using a sprocket tooth counter speed sensor or internal pulse gearbox speed sensor enter the number of pulses per wheel revolution into the pulses screen.
