Xiaomi Tuning for all software versions, Mi 3 S1 S2 Pro

SpeedChip once the tuning is connected, you can turn on and use the scooter as normal. The tuning is only activated after quickly pressing the scooter's power button 6 times. Then, instead of 20 km/h, the scooter reaches speeds of up to 31–36 km/h.
After turning the scooter off, the tuning automatically deactivates. Every time it is switched on, the scooter starts in normal mode — the 20 km/h limit is active.
If you press the power button 6 times quickly, the tuning reactivates until the scooter is turned off again. This allows you to conveniently decide when the limit is active and when it is disabled. The tuning is invisible from the outside.
The original display correctly shows higher speeds

Important information: in Poland, according to regulations, the maximum permitted speed for an electric scooter in public traffic is 20 km/h. Modifications that increase speed may lead to loss of road legality, voiding of the warranty, and insurance issues in the event of an accident. Therefore, any changes should be used only on private property and at your own risk.
