PearTune MSO 4.0 for Specialized 1.1 / 1.2 SL with Original Speed Sensor

PearTune MSO 4.0 for Specialized 1.1 / 1.2 SL with Original Speed Sensor

This tuning tool for Specialized 1.1 SL e-bike drives offers numerous optimisation options. The core function is, of course, the unlocking of the e-bike, which means nothing other than the removal of the 25 km/h speed limit (MSO = "Max Speed Off"). In addition, the maximum speed can even be set to an individual value.

Tuning can be switched on and off at any time using the control buttons on the e-bike. Even when tuning is active, the e-bike display shows the correct speed.

This version of the PearTune 4.0 tuning module comes with a high-quality original speed sensor. The module must be installed in the engine compartment and connected to the corresponding plug connections.

As the power is supplied via the e-bike, the module does not need its own battery.

PearTune 4.0 for Specialized 1.1 / 1.2 SL with Original Speed Sensor - Features at a glance

-25 km/h speed limit is removed.

-E-bike display shows correct values, even with active tuning (current speed).

-Max. Speed adjustable: The maximum supported speed can be set to an individual value by pressing the + and - buttons (from 26 km/h upwards). After 10 seconds of inactivity, the last selected speed is automatically saved.

-Chip activation: By default, tuning can be switched on and off at any time by briefly pressing the WALK button or using the + and - buttons.

-Chip activation: Selection of the buttons with which the tuning can be activated/deactivated (e.g. by means of the LIGHT button, WALK button or + & - buttons).

-Chip lock: When the chip lock is activated, the tuning cannot be activated with any button. This can prevent unauthorised access to the tuning.

-Start of the chip: You can specify whether the Tuning Chip should initially be INACTIVE or automatically ACTIVE when the e-bike is switched on (permanent or deactivable).

-Addition of the correct kilometres travelled: When riding with the tuning chip activated, the distance travelled no longer matches the distance actually travelled. However, you can add the correct kilometres, whereby you can determine the calculation method yourself, e.g. by adding kilometres while driving and standing still or only when stopping, etc.

-Chip reset: If you want to install the tuning chip in another e-bike or when replacing the speed sensor, a chip reset must be carried out. The old settings can be retained; alternatively, the chip can also be reset to the default settings.

-Chip software version information: The current software version of the chip can be shown on the display.

Reset

A reset can be carried out if required. Proceed as follows:

-Set the highest support level.

Press the following buttons 19 times: - + - + - + - + - + - + - + - + - + - + -

-The number 19 should now appear on the display.

-And a few seconds later the number 1 or 11 will appear.

-Immediately at this moment, press ONE more time on the - button.

-This press changes the number 1 or 11 to either number 2 or 12.

-Now wait briefly until 0 (zero) appears - this completes the reset!
