PearTune MSO 4.0 for Yamaha PW-X, PW-SE, PW-TE, PW-X2, PW-ST, PW-CE (2019-2022)

PearTune MSO 4.0 for Yamaha with Displays A / C

This version of the popular PearTune tuning module offers far more functions than the previous models. The core function is and remains, of course, the removal of the 25 km/h speed limit - accordingly, "MSO" also stands for "Max Speed Off". Even with active tuning there is a correct speed indication in the display.

But the PearTune 4.0 can do much more: For example, for the first time there is the option to set the maximum speed to an individually desired value using the control buttons of the e-bike. A real special feature is the so-called "chip lock" function. Thanks to this feature, the tuning module can be made "invisible", so that outsiders can no longer recognise that a tuning tool has been installed (e.g. the e-bike and display will then function normally, and the tuning cannot simply be activated).

The PearTune MSO 4.0 module must be connected to the motor between the motor and the display and between the motor and the magnetic speed sensor. To facilitate installation, the tool is equipped with matching original connectors ("Plug & Play" principle). The tuning can be switched on and off at any time using the operating buttons.

PearTune MSO 4.0 for Yamaha - Functions at a glance

-25 km/h speed limit is completely removed.

-Maximum speed individually adjustable: The maximum speed can be individually adjusted using the + and - control buttons, in 1 km/h steps.

-Correct speed indication in the display, even when tuning is activated.

-Chip lock ("Lock the Chip" feature): With this function, the tuning module can be made virtually invisible. If the chip lock is switched on using the control buttons on the e-bike, the tuning chip is locked on the software side so that no one can recognise that a tuning tool has been installed. In this case, the e-bike and display function normally and the tuning cannot be switched on. Unlocking again is only possible with a certain key combination.

-Chip activation: The tuning chip can be switched on or off at any time by briefly pressing the light button twice. When switching on and off, the display briefly shows whether the tuning has actually been activated or deactivated for confirmation.

-Tuning status when switching on: With PearTune 4.0, you can set whether the tuning should automatically be ON or OFF when the e-bike is switched on.

-Chip reset: You can perform a chip reset, e.g. if you want to replace the speed sensor or use the tuning chip on another e-bike. The factory settings can be restored during the reset. Alternatively, you can keep the chip settings.

-Adding the correct kilometres travelled: When the tuning is switched on, the actual distance travelled is no longer displayed during the ride. Now you can set how the missing kilometres are to be recalculated or supplemented - for example, only when stopping, or also as a supplement while driving and when stopping, etc.

-Switch between Normal and Still On version possible (with the Still On version, the tuning is always active as soon as the e-bike is switched on / suitable for e-bikes without the necessary control buttons).

-The module does not require its own battery (power is supplied via the display plug).

-Plug & Play: For easy installation, the tuning module is equipped with original connectors.

-Small, compact & light: The module is very small and therefore easy to install. The weight is just 12g.
