PearTune MSO 3.0 for Shimano EP8 / EP8 RS / EP800

PearTune MSO 3.0 Normal for Shimano EP8 / EP8 RS / EP800

This tuning tool removes the speed limit of Shimano EP-8 motors - "MSO" stands for nothing else than "Max Speed Off"!

The Shimano STEPS EP-8 motor is the long-awaited successor of the popular E8000 motor. Compared to its predecessor, the EP-8 is not only smaller and lighter, it also has an enormous torque of 85 Nm - and thus over 20 percent more power!

Unfortunately, the enormous power of this drive is limited by the preset 25 km/h speed limit. But this is where the PearTune MSO chip comes into play. This is a tuning module that has to be connected to the EP8 motor. Once this is done, the speed limit can be lifted at any time by pressing a button, so that the engine can actively support you even at much higher speeds. This means you can finally enjoy unlimited driving fun without limits!

With active tuning, the e-bike display shows the correct speed up to a speed of approx. 23 km/h, after that the displayed speed is "frozen". This means that approx. 23-25 km/h will always be displayed, even if you are riding much faster in reality.

Please note: If you have an e-bike WITHOUT display, please choose the StillOn version of this tuning module. In this case, the tuning is always active as soon as you switch on the bike.

Installation

The PearTune MSO 3.0 is a microcontroller-based module that must be connected to the motor using the two black cables between the magnetic speed sensor and the motor. To do this, the motor cover must be temporarily removed. The connection to the motor is made using original connecting plugs. If the light function of your e-bike is enabled and you want to use the option of deactivating / activating the tuning via the light function, you must also connect the red cable to the "+" port.

If you have an e-bike WITHOUT an activated light function or without a display, you can ignore the red cable. You do not have to connect it. In this case, the tuning remains permanently active as long as the e-bike is switched on.

After installation, the module configures itself automatically, you do not need to do anything else.

You can remove the PearTune module at any time if you want to restore the e-bike to its original condition. This will not leave any traces on the e-bike.

Compatibility

This tuning tool is only compatible with the following Shimano STEPS e-bike motors:

-EP8 / EP800

-EP8 RS

Compatible with all displays

ATTENTION: There is a new Shimano software update version 4.30 (approx. July 2024). It is currently NOT yet certain whether this tuning module is compatible with it. We are currently testing this. This means: If your Shimano e-bike is equipped with software version 4.30, you should wait a little longer before ordering until we have been able to confirm compatibility.

ATTENTION: NOT compatible with EP6 and EP801 motors! In this case, please select the "PearTune MSO 3.0 for Shimano EP801/EP6".

Tip: If you have a Shimano EP8 / EP8 RS e-bike without a light function or without a display, you can also choose this tuning tool in the special "StillOn" version - this means that the tuning will be always active as long as the e-bike is switched on (the tuning cannot be deactivated).

Tips:

Before installing the PearTune module in a brand new e-bike, you should first ride the bike for at least 1 km.

The manufacturer expressly advises against software updates, as the tuning may then no longer function properly.
