Pear Tune chip for e-bike MSO 4.0 Bafang M500/510/200/410

Description

PearTune is easily integrated into the e-bike system using compatible original connectors.

No need to set up or use diagnostics during installation – everything happens automatically and adjusts to the specific e-bike.

PearTune is connected between the speedometer sensor and the motor unit, and between the display and the motor unit. It is powered by the display. All data such as current, average, and maximum speed or distance traveled are accurately displayed.

PearTune MSO can be turned on or off at any time while riding by pressing the light button twice long, or by pressing the + and - buttons four times short.

The main advantage is that after installation, the maximum speed of the e-bike is no longer restricted – it is determined only by the pedaling frequency.

Installation:

Unscrew the plastic cover on the side of the motor where there is no chainring to access the necessary cables and connectors between the motor and the bike frame.
Disconnect the 8-pin connectors between the display and the motor and between the speed sensor and the motor.
Connect the PearTune connectors in place of the original connectors to the motor unit. PearTune connectors are marked in red and must be connected precisely in their place.
Position the chip in a suitable place, such as in the bike frame, ideally with the chip body facing up, and secure the cables. Then replace the plastic cover and tighten the screws.

Usage:

PearTune MSO can be activated/deactivated at any time while riding by pressing the LIGHT button twice LONG or by briefly pressing the + button and then immediately the - button.

The original functions of these buttons remain unchanged. PearTune MSO activity is indicated on the display with a value of 9.9 km/h or 6.2 mph (PearTune is activated) and 2.5 km/h or 1.6 mph (PearTune is deactivated) for a few seconds after activation/deactivation. If you have the "Still ON" version, you do not need to do anything for activation = the chip is activated/deactivated automatically when the bike is turned on/off. If you have the 4.0 SMART version, you can change the activation buttons in the CHIP SERVICE MENU as desired.

If you plan to install PearTune MSO on a new e-bike, make sure you ride at least 1 km on it before installing PearTune MSO. It's possible that during prolonged riding at speeds over 25 km/h with motor assistance, some data on the display may not immediately respond to their actual values. After some time without motor assistance or at speeds below 25 km/h, these values should always adjust. After a longer ride at higher speed, we recommend not turning off the e-bike immediately. The simplest way is to let the e-bike turn off automatically or keep the bike ON after the ride until the display shows a value of 0.0 km/h or 0.0 mph.

Do not perform bike software updates after installation to avoid functionality issues with the chip.
