PearTune MSO Tuning for Yamaha PW-X3 and S2

Season:2023

Brand:PearControl

Code:PT-MSO-PW-X3/S2

PearTune for the Yamaha PW-X3 motor is connected to the e-bike system with compatible and original connectors. The MSO does not need to be configured manually. The entire configuration and adaptation to the particular e-bike are done automatically. The MSO is connected in between the magnetic speed sensor and the motor unit, and in between the display and the motor unit. MSO is powered from the display connector. All readings like actual speed, max speed, average speed, distance etc. are correctly displayed. The MSO can be activated or deactivated anytime during the ride by pressing the LIGHT BUTTON or --++. The device state is indicated by a certain element on the display, so the rider always knows whether the device is active or not. Thanks to original connectors the e-bike tuning can be de-installed without any signs and original Yamaha diagnostics (highest level) did not find any signs of the device after removal. The only difference is that from the moment of installation you, not your bike, determine how fast you go. The maximum speed is limited only by the pedalling frequency.

Usage
The MSO can be activated or deactivated anytime by once short-press of the light button (LIGHT) or --++. The original function of this button remains unchanged with a long-press and the walk assist function can be used like before.
