PearTune MSO 3.0 for Shimano EP801 & EP6

PearTune MSO 3.0 for Shimano EP801 / EP6

No more speed limit!

This tuning module completely removes the 25 km/h speed limit from e-bikes with Shimano EP 801 & EP 6 motors (whether with or without Di2 gears). Consequently, the abbreviation "MSO" stands for nothing other than "Max Speed Off”.

This means you can ride much faster than 25 km/h with full motor support; the actual achievable speed is ultimately only limited by factors such as cadence, motor power, etc.

The PearTune module does not require its own battery as it is powered by the e-bike battery.

 

Tuning can be switched on and off

The tuning is automatically activated as soon as the E-Bike is switched on (=speed limit lifted).

If the E-Bike has an activated light function, the tuning can be switched off or on again at any time by using the light button.

Important: When tuning is active, the E-Bike display will only show the correct speed up to around 21-25 km/h. At higher speeds, the displayed speed will be "frozen" so that the same value is always displayed.

Tip: To display your real speed on the road, we recommend using GPS-enabled additional devices such as your smartphone. It is best to attach it directly to the handlebars so that you always have all the data in view. You can find practical mounts in stores.

 

Simple Installation

The PearTune 3.0 is a module or chip that must be permanently installed in the motor housing of the e-bike. The connection is made using waterproof plug connections.

Please note that the motor cover must be removed briefly during installation in order to gain access to the corresponding plug connections. If you want to use the option of switching the tuning off and on again via the light function, the red cable must also be connected to the "+" port.

If your e-bike does not have a light function or light button, you can simply ignore the red cable.

After installation, the module configures itself and you don't need to do anything else.

If you wish, you can remove the PearTune at any time if you want to restore the e-bike to its original state.

 

Compatibility

-Compatible with e-bikes with Shimano EP801 & EP6 drive systems.

-Compatible with all displays.

-Compatible with models both with and without Di2 shifting.

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.

Tip: If you have an e-bike with Shimano EP8 / EP8(00) or EP8 RS engine, please choose the "PearTune MSO 3.0 for Shimano EP8".

Important notes:

-Before you install the PearTune in a brand new e-bike, you must have ridden at least 1 km on the bike beforehand.

-We generally advise against software updates on the e-bike, as the tuning may no longer work afterwards.

-The ACC connection must be activated for the tuning to work correctly with EP801 and EP6 drives! Unfortunately, this is not the case with all models. If the ACC connection cannot be activated, the module can alternatively be connected to the light. The disadvantage of this solution is that activation via the light is not possible in this case, and the light must always be switched on.
