Tuning module for the Yamaha PW-X3 and PW-S2 drive system.

Compatible with the PW-X3 and the PW-S2 motor and the displays Sideswitch (Display A), Multiswitch (Display C), Display X and the Interface X. For bikes with other Yamaha drive systems, please refer to the following selection guide.

Not compatible with the Yamaha MORO 07.

Features

• Automatic initialization, immediately ready for operation after installation – plug and ride.
• Tuning can be turned on or off via the arrow keys on the control unit.
• After activation, the speed limit can be freely set in the range 25 – 45km/h (15.5 – 28mph) using the arrow keys. The last set value is saved.
• The tuning is always turned off after the bike is powered on.
• Setting of a smoother “throttling behaviour” possible (dynamic mode). The otherwise very abrupt motor cut-off at the speed limit is thereby significantly softened.

• Individual activation code adjustable (additional display required for Interface X)
• Correct display of speed and distance traveled at all times.
• Residual range calculation from current riding style with active tuning. 
• Correct total mileage reading even after removing the tuning module, because the kilometers in the motor control are corrected by the tuning module.
• Wheel circumference adjustable (+/-10%) to improve the accuracy of the speed display and distance measurement (additional display required for Interface X).

The device is installed invisibly from the outside on the motor. No cables have to be damaged or modified, the module is simply plugged in and is immediately ready for use. 

No PC or smartphone is required. All settings are made via the display control buttons on the bike.

A unique feature is the ability to set both the speed limit, the downshift behavior and the wheel circumference via the display. In contrast to the almost complete elimination of the speed limit with other tuning modules, this module still allows a very sporty riding style with moderate battery consumption by slightly increasing the limit, e.g. to 32km/h. For a more natural riding experience, the dynamic mode spreads the power reduction over a wider speed range, the so-called "wall effect" is significantly reduced.

Notes interface X

With the interface X, the operating states and setting values are displayed via the battery LEDs. Further information on this can be found in the following document:
