If it has wheels and an engine then yes, it is suited. Every ACEWELL is a stand-alone unit and can be fitted to any vehicle. Different models offer different features so you may choose one model over another depending on your purpose.

ACEWELL have a couple of options for vehicles with no onboard battery. The ACE-1500 and ACE-1600 models both have an internal battery but have the most basic features of the range. To get the other models going off an AC power source like a stator you will need the ACE-F351 power filter to convert the power to DC.

The ACEWELL range comes standard with a magnetic reed sensor kit, which includes a button magnet and a M6 magnetic bolt. A speedometer cable accessory for motorbikes that converts the mechanical drive out of the wheel Hub or gearbox to a digital signal for the ACEWELL gauge is sold separately. Check the website for fitting.

The ACEWELL range comes with a tachometer sensor lead (Yellow) that is designed to wrap around any one of the spark plug leads, this can also be hard wired to the negative of the ignition coil. The ACEWELL gauge can be calibrated to most engine types.

Each ACEWELL comes with a mounting bracket for a single mounting point, but that does not mean you have to use it as the ACEWELL also has two mounting bolts on the back of the body.

A bracket designed for triple clamps on a motorcycle can be bought separately, some uses will be make their own bracket to suit a specific custom fitment.

The spark signal from the engine is either too strong or too weak for the ACEWELL to tolerate. Reduce or increase the amount of times you have wrapped your yellow tachometer cable around the spark lead or add the supplied resistor to the tachometer sensor in line. Either or both of these steps will aid in reducing or increasing the spark signal strength and will allow the ACEWELL to tolerate the signal.

Check that your ACEWELL is set to the right “revolution per spark” setting for your engine. If you are unsure of the spark signature of your engine you can use trial and error and cycle through the different options until the tachometer gauge is reading correctly, this will not damage the bike or Acewell. The spark signature settings of your ACEWELL can be found in the instruction manual.

This is an issue caused by an incorrect calibration. The speedo runs off a signal produced the magnetic sensor which is triggered by the passing magnet on the wheel. This signal is divided by the wheel circumference inputted by the user in millimeters ( cXXXX on the calibration menu).

Measure the circumference by marking a point on the tyre and the ground and rolling the bike forward a full revolution mark a second mark on the ground. This distance in millimeters is entered into the calibration menu.

This is usually caused by an incorrect mounting of the sensor compared to the magnetic bolt. The sensor has two notches on its barrel, one at the top and the bottom. The magnet must pass along either the top or bottom notch at a distance no more than 8mm.  If the set up is incorrect the magnet may pass both notches at once and cause a spike in the signal, this will cause the speedometer to read inconsistently.

A standard cable drive Hub will complete more than one revolution per full turn of the wheel. Most common ratios are 3:1 or 4:1 (turns of the cable drive : turn of the wheel). When you input the data you can divide the circumference of the wheel by how many rotations the cable does for 1 turn of the wheel. Eg 3:1 cable drive ratio – tyre circumference of 1200mm divided by 3 = 400 (adjusted calibration number). Calibration should be c0400 in the menu.
