READ BEFORE INSTALLATION:
Be sure to update the firmware of the Rapid Bike Evo / Racing module with the
latest version available in the Rapid Bike Master software ver. 2.0.6.8 and further
In case one or more My Tuning Bike devices are installed on the bike, proceed with
its firmware upgrade too (refer to the software manual for both procedures).
NOTE: software advises automatically to proceed with upgrade if it is opened with
bike’s ignition ON.
WARNING

Button (+) increases the
value displayed. Pressed
together with button (-)

brightness
Six LEDs indicating the selected feature:
TC => Traction Control
EB => Engine Braking
QS => Electronic Quick Shifter
AFR => Air Fuel Ratio
LC => Launch Control
RPM => Revolutions per Minute
Button MODE selects the
feature and saves new
settings (memorizing new
default feature)
Installation
1. Fasten the device, using the provided Velcro, in a position easy to
look at and reach (see pictures).
2. Route the wiring harness up to the
Rapid Bike module and fasten it to
the OEM harness using cable ties.
3. Connect the three connectors of the
Youtune harness to the Rapid Bike
harness.
Turn ignition on.
4. The device must light up all the LEDs as well as the display; then it
should set to RPM position showing 0 rpm.
The device is ready.
WARNING
The device flashes continuously in case a communication problem is detected:
1. Update the Rapid Bike module’s firmware as mentioned previously.
2. Youtune harness may have been damaged during installation. Check it and
repair.
