RPM sensing wire:
1. Signal intensity from ignion coil is dependent on vehicle type.
FUNCTIONS
BAR RPM: Bar Graphic Tachometer
The bar tachometer has 10,000rpm and 20,000rpm opons.
Km/H or MPH: Speedometer
1. Displays speed meter up to 399.9 Km/H or 248.5 MPH.
2. Decimal of speedometer can be oponed by user.
3. Maximum input frequency 7KHz .
4. If a frequency of 7KHz is reached before the speed reaches 399.9Km/h
then the maximum speed will be lower. With a 1277mm diameter wheel
and the speed input connected to an ABS sensor producing 105 pulses
per revoluon the maximum speed displayed at 7KHz would be 250Km/h.
RPM: Digital Tachometer
1. It displays digital tachometer up to 19,990RPM and displays 19,999rpm
when tachometer is over 20,000rpm..
2. Tachometer signal can pick up from either CDI or Ignion Coil Signal.
: Shift Warning RPM
1. The funcon enables you to set up a shi warning RPM.
2. Shi warning LED indicator flashes when RPM reaches preset value, and
stops flashing aer you shi gear.
MAX RPM: Maximum Tachometer
Displays highest tachometer achieved since last Reset operaon.
MAX SPD: Maximum Speed Meter
Displays highest speed achieved since last Reset operaon.
AVG SPD: Average Speed Meter
It calculates average speed from last RESET. The AVG is calculated from
TRIP be divided by RT.
ODO: Odometer
1. ODO accumulates total distance traveled.
2. ODO data is adjustable when it is less than 30km (18.6 Miles), aer that
it stored in memory and cannot be reset.
RT: Riding Timer
1. Calculates total running me since last RESET.
2. Counter automacally begins with movement.
TT: Total Riding Timer
1. Calculates total running me since last RESET.
2. Counter automacally begins with movement.
HRT: Hour Meter
1. Calculates total engine operaon me since last RESET.
2. Counng automacally begins when revs are detected.
3. HRT data is stored in memory, and cannot be reset.
: 12/24 hour Clock
Displays 12 or 24 hour current me.
: Bar Thermometers
1. Has 7 bars to indicate engine temperature.
2. The 4th bar counng from boom is turned on when thermometer
reaches the preset warning temperature, each 15°C increase lights
another bar.
3. The bar-temperature flashes when the measured temperature is higher
than the preset warning temperature.
4. The over temperature LED flashes when either temperature input 1 or
input 2 exceeds preset warning temperatures or is connected to –ve.
Excellent water resistance, an-vibraon structure and noise immunity
design.
**EM & IR receivers and IR transmier for automated lap ming are
available as accessories.
2. Coil 2-5 turns around spark plug lead, with more turns creang steadily
stronger signal, fewer turns creang weaker signal.
3. The RPM circuit is designed for most bikes, however some bikes’ signal is
too strong if the RPM looks like much more than actual RPM and unstable,
please connect the included 1M Ohm resistor in series to solve it.

Reed Speed Sensor and Magnet:
1. This sensor is universal sensor for motorcycle, find a rotang part to install
magnet (for example disk, sprocket or drivesha) and a locaon 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 vibraon direcon creates oponal
an-vibraon 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.
Specific Hall sensors:
Cable drive adaptors for most bikes originally fied with cable driven
speedometers or milemeters are available. When using these cables it is
necessary to divide the circumference seng by the number of rotaons of
the cable per rotaon of the wheel or enter the number or rotaons into the
“P” screen in setup.
Hall Effec Speed Sensor and Magnet:
1. This is universal sensor for ATV front or rear wheel installaon or
motorcycle front wheel installaon. For some fitments an accessory speed
sensor holder may need to be purchased.
2. Find a rotang part to install magnet (for example disk, sprocket or
drivesha) and a locaon 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.
*Thermo Sensor and Sensor Tube:
1. The unit includes a water temperature sensor; you have to purchase a
suitable water pipe temperature sensor tube to install the sensor easily.
2. Cut the water pipe, insert the temperature tube into the pipe and secure
it by aached pipe clamps.
3. Screw the sensor into the tube.
4. If your vehicle is fied with a thermostat that stops water flowing to the
radiator when the engine is cold, you will not get a reading unl the
thermostat opens.
**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.

value of the 6 values. Press MODE buon to confirm the seng and go
to wheel circumference seng screen.
8. In "SPD cXXXX" display, "c" means "Circumference in mm", following 4
default digits; flashing digit is digit to be set. Follow the item 2 of
buon operaon to finish the wheel circumference seng and jump
to signal divider seng to set the number of pulses from the speed
sensor per turn of the wheel.
9. It displays "SPD P-001" for signals to be divided. Follow item 2 of
buon operaon to finish the seng and jump to unit seng.
10. It displays KM/H or MPH, each press of RESET buon converts unit;
press MODE buon to confirm unit seng and jump to speedometer
decimal point seng.
11. It displays “SPD 99.9Km/H” on or “SPD 99Km/H off”, the decimal
point will not be displayed when “off” is selected. Follow the item 2
of buon operaon to finish the decimal seng and jump to
maintain reminder seng.
12. It displays and RT, TRIP or OFF. RT has default of 100 hours, TRIP
has 1000km (621Miles) default. Follow the item 2 of buon
operaon to finish the maintain reminder seng and jump to
voltage warning seng. The maintain reminder funcon will be
disappear when select “OFF”.
13. It displays “ b-on and a flashing numbers of voltage” to be set,
“b-on” means baery warning on voltage – when the voltage falls
below this the LED will come on, seng range from 11.0 to 14.9V. It
displays “ b-off and a flashing numbers of voltage”, “b-off” means
baery warning off voltage, seng range from 11.0 to 14.9V to, but
b-off voltage must larger than b-on voltage – when this voltage is
exceeded the LED will go off. Follow the item 2 of buon operaon
to finish the voltage warning seng and jump to temperature unit
seng.
14. Thermometer 1 seng It displays " 1 °C , °F or oFF", each press of
RESET buon converts °C , °F or Off, the temperature bars will
disappear when you select oFF mode; press MODE buon to confirm
temperature seng and jump to temperature warning seng.
**LAP review operations:
1. In the LAP mode, press MODE buon to review the 1st storage data, it
displays number of lap and lap mer.
2. Press the LAP buon to switch between lap mer or average speed of
the same LAP; each press of the MODE buon displays data for the next
lap.
3. Press and hold LAP buons for 2 seconds to go out LAP mode and return
to normal mode.

1. The details below have been calculated using following formula: Tire
Diameter (inches) x 25.4(mm/inches) x 3.1416 = wheel circumference
(in mm).
2. Idenfy the re size (not wheel size) of your ATV/Motorcycle when you
need to change different re size and key in the corresponding number
shown in the following chart.
3. These values are approximate and will differ for different brands of re,
we would always recommend that you measure the distance travelled
per revoluon of the wheel in mm and enter this into the computer.
4. The computer calculates the wheel rotang length between 2 passes of
the magnet; use this table to find the sengs when you are using a reed
sensor or an universal hall sensor with magnet to measure your speed.
5. If you are using a cable drive speed sensor then enter the number of
turns of the speedo cable per turn of the wheel into the “p” screen.
6. You can use more magnets, but the number of magnets must be entered
into the “p” screen.
7. The computer has a built-in soware divider (“p” screen) seng from
1 to 199 for different speed signal applicaon, refer to the divider
setup, one means one wheel revoluon creates one signal. You have
to input the number of signal per wheel revoluon to have a correct
speed.
