PearTune MSO 4.0 for Specialized 1.1, 1.2, 1.3, 1.2E & 1.2S engines

PearTune MSO 4.0 for Specialized 1.1, 1.2, 1.3, 1.2E & 1.2S

This tuning module allows you to optimise your Specialized e-bike in many ways. The core function is the removal of the speed limit - you can therefore make your vehicle faster ("MSO" = "Max Speed Off"). With the PearTune MSO 4.0, there is now even the option to individually set the maximum supported speed.

In addition, you benefit from many cool additional features - especially original is the "chip lock" with which you can make the module virtually invisible to others. The e-bike then functions as if no tuning tool had been installed - outsiders can no longer see that the e-bike has been tuned. Only after a certain period of time has elapsed the module can be reactivated by means of a certain key combination.

You don't need a PC or smartphone to operate the module, you can control everything using the control buttons on your e-bike.

The PearTune MSO 4.0 is a module that must be attached to the e-bike with original connectors. It is connected between the display and the motor as well as between the magnetic speed sensor and the motor. Thanks to the "Plug & Play" principle, no complicated configuration is required.

Tuning can be switched on and off

You can activate/deactivate the PearTune module as required. However, there are differences depending on the e-bike model:

-By pressing the WALK button - depending on the model, either a long press (e.g. on the latest VADO 2022) or a short press (e.g. on the old LEVO e-bike) is required.

-Activation by pressing +-+- four times.

-Activation by ++-- or --++ or +-+- or -+-+

When you activate or deactivate the tuning, a short confirmation appears on the display.

PearTune MSO 4.0 for Specialized 1.1, 1.2, 1.3, 1.2E & 1.2S - Functions at a glance

-Removal of the 25 km/h speed limit.

-Maximum speed individually adjustable (in 1 km/h steps using the + and - buttons).

-Tuning can be switched on and off via the bike's control buttons.

-When tuning is active, the correct speed is only displayed up to a speed of approx. 25 km/h. At higher speeds, the displayed speed is "frozen".

-Chip lock ("Lock the Chip"): Here you can make the tuning practically invisible to others. Switch on the chip lock with the control buttons of the bike to lock the module on the software side. The e-bike will then function normally - as if no tuning tool had been installed. The tuning can also temporarily no longer be activated. Only after a certain period of time can the tuning be reactivated with a specific key combination.

-Individual activation code can be set.

-Tuning status when switching on: Specify whether the tuning should be active or inactive when the e-bike is switched on.

-Switch between NORMAL and STILL ON version possible: If your e-bike does not have the control buttons required for activation/deactivation, you can switch to the STILL ON version via the service menu - in this case the tuning is always active as soon as you switch on the bike. Tip: If your Specialized 1.1, 1.2, 1.3, 1.2E or 1.2S e-bike does not have a display with indicator, we recommend the “PearTune MSO for Specialized 1.1 (Gen1), 1.2, 1.3, 1.2E and 1.2S engines” in the STILL ON version.

-Chip reset: If you want to connect the PearTune module to another e-bike or change the speed sensor, you can perform a chip reset. You can keep the chip settings or restore the factory settings.

-Adding the correct kilometres travelled: If the tuning module is switched on, the distance travelled is no longer displayed correctly. With PearTune MSO 4.0, you can now set how the missing kilometres will be recalculated or supplemented - e.g. only when stopping, or also as a supplement while driving and when stopping, etc.

-The tuning module does not need an extra battery, the power is supplied conveniently via the e-bike battery.

-Plug & Play: No annoying configuration necessary.

-Connection via original connectors.

-Since the PearTune module is very small, it is easy to install. The weight of the module is just 12 g.
