PearTune MSO 3.0 tiuningo rinkinys Avinox DJI M2, M2S

The PearTune MSO Avinox DJI M2/M2S tuning chip is an add-on device developed by PearControl for e-bikes with the Avinox drive system. with M2/M2S version motors. It is used to remove the speed limitation of the e-bike pedaling at 25 km/h. The product is designed with minimal dimensions for easy installation in all e-bike models from all manufacturers on the market and for flawless cooperation with the speed sensors in the original Avinox DJI system.

The tuning kit manipulates the speed signal without altering the motor's power relative to pedaling speed. This guarantees a smooth motor control without speed limit interruptions. Depending on a tuning kit, some determine when assistance stops, while others remove the restriction entirely for continuous support. However, the achievable speed mostly depends on the eBike model. Achievable speed can be calculated using a simple formula:

Speed = Cadence [rpm] * Wheel circumference [mm] * Front Chainring Teeth / Rear Chainring Teeth * 60 [min/h] / 1.000.000 [mm/km]

Activation/Deactivation can be done in this way:
• by pressing the – + – + button combination (i.e. 4 presses) , start from the TURBO assistance mode by pressing the MINUS button . Chip activation is indicated by the display of 19 km/h instead of the current speed for 2-3 seconds. Chip deactivation is indicated by the display of 12 km/h instead of the current speed for 2-3 seconds. Calibration is performed completely automatically when the chip is first turned on or off

Displaying values

When riding with the chip on, the e-bike display correctly displays the actual speed up to 22.9 km/h. After exceeding this value, the actual speed is displayed on the last two digits of the display, for example: 23.3 corresponds to a speed of 33 km/h, 24.2 corresponds to a speed of 42 km/h, etc.

The device is fully compatible with the Avinox DJI M2/M2S motor and all displays available on the market for these motors.
