3.6 Activating the km/h to MPH conversion feature
Press SEL until the actual mode ([ C ] or [ - ]) is displayed and keep it depressed for one more
sec, until the value toggles.
When Km/h to MPH conversion is active, indicated speed and distance travelled will be
converted, but the displayed units of measure (km/h and km) won't be changed.
It is possible to toggle on/off the Km/h to MPH conversion only.
If you wish to use MPH to Km/h conversion, you have to program +60.9% (1.609 multiplier)
on top of the calibration value you need. However, keep in mind that your speedometer's
maximum reading will not be changed. E.g. a speedo with 186 MPH highest reading will not
be able to show over 186 Km/h after conversion.
3.7 Top Speed Memory function
Connect the 2-pole plug of the remote button to the unit's TSM socket.
The SH continuously records the highest speed in Flash memory.
-
To recall the top speed, press and release the remote button.
The top speed is shown on the speedometer for a few seconds, and the SH display will count
from [ 5 to 0].
-
To reset the Top Speed memory, press and holdthe remote button for at least 2 seconds.
The speedometer will read 0, and the SH display will indicate [ E ] (Erased).
3.8 Test mode
In Test mode, you can check whether the SH is installed and workind properly.
To initiate test mode:
-
Have the ignition OFF.
-
Press SEL and keep it depressed while you turn ignition ON.
[ t ] (test) is now indicated. Release the button.
The speedo should indicate a number a other than zero. If you wish, you can change the
speed reading in 9 steps by pressing SET repeatedly.
-
Rotate the rear wheel. [ t ] should be blinking as the wheel turns.
-
Press SEL to exit from Test mode. The unit will work normally.
4.Calculations
4.1 Precise method
If you have access to a good speed reference, such as a GPS, radar speed sign, dynamometer
(dyno) or another vehicle with accurate speedo:
Read your indicated speed when the actual (reference) speed is e.g. 60 mph or 100km/h.
Repeat the measurement to make sure you get consistent results. Then use the following formula
to get the calibration value you need:
(
SH
Calibratio
Example:
If your indicated speed was 66 mph at 60.0 mph actual (reference), the calibration value would be:
-9.09% --> -9.1%
4.2 Estimated method
Use this method when speed reference is not available and you have changed you gearing.
The following formula takes into account the standars and new sprocket sizes, as well as 5%
factory speedo error (typical for most bikes).
