How to increase the speed of the Xiaomi M365 scooter: a complete guide to overclocking

The Xiaomi M365 series is deservedly considered a benchmark of reliability in its class, but their standard speed of 25 km / h is often limited by software locks to meet European safety standards. Many users wonder how to unlock the full potential of their device to feel more confident in the flow of urban transport. Owners of the Xiaomi M365 Pro or the regular version of the 1S often face artificial “strangulation” of dynamics, which can be eliminated by software methods.

There are several proven ways to get around factory restrictions, from simply changing the region in the application to completely flashing the controller. It is important to understand that any interference with the program code of the device removes the warranty, so you need to act carefully. In this article, we will look at safe and effective methods that will allow your scooter to reach speeds of 30-32 km / h and even higher, depending on the battery charge and weight of the rider.

Before making modifications, you need to learn the basic principles of the BMS and controller control system: the software speed limit is not a physical barrier, but a software code that prevents the controller from applying voltage to the motor above a certain threshold, removing this restriction opens up access to the real characteristics of the engine, laid down by the manufacturer.

Programmatic limitations and overclocking physics

The factory firmware of the Xiaomi M365 electric scooter severely limits the maximum speed to 25 km / h. This is done to comply with the legislation of the European Union, where this class of transport is equated to bicycles. However, technically, the motor-wheel and battery can produce much more power. The scooter controller receives data from Hall sensors and limits the current, preventing it from developing a higher speed.

The physical speed limit depends on the battery voltage. At full charge (42V), the scooter accelerates faster than at 50% charge (about 36V). The software hack allows the controller to ignore the software limit, but can not overcome the laws of physics. If the battery is discharged, even the modified scooter will not go faster than the stock value.

⚠️ Attention: After removing software restrictions, the braking distance increases. Make sure your brake pads are no more than 50% worn and be prepared for sharper braking at high speeds.

Also, consider the aerodynamic drag, which increases exponentially with increasing speed. Acceleration from 25 to 30 km / h requires much more energy than acceleration from 15 to 20 km / h. So the autonomy after the modification will inevitably decrease if you actively use the maximum speed.

💡

Before making any changes to the firmware, be sure to fully charge the scooter to 100%. Interrupting the process of writing data at a low charge can lead to the "bricking" of the controller.

Change of region in the Mi Home app

The easiest and safest way to increase speed is to change the region in the official Mi Home app, which manufacturers often set different speed limits for different markets, such as China or the United States, which may be milder than in Europe, and which does not require a computer connection or third-party software.

To do this, you'll need to delete the current region in the app settings and select a country with less stringent regulations, often by switching to the "US" or "China" region. After changing the region, you need to re-attach the scooter to your account, in some cases, this immediately removes the 25 km/h limit, allowing you to accelerate to 27-28 km/h.

• 🇺🇸 USA: often allows for acceleration to 28-29 mileage.
• 🇨🇳 China: may require a change of language, but gives access to full functionality.
• 🇪🇺 Europe: strictly limited to 25 km/h (standard mode).
• 🇷🇺 Russia: settings may vary depending on the version of the application.

But this method doesn't work on all firmware versions, and if a vendor upgrades firmware on the server side, simply changing the region may not work, and then you'll have to resort to more radical measures, such as custom firmware.

Installation of custom firmware Dash

The most effective method is to install modified firmware, the most popular of which is Dash. This firmware completely removes software speed limits, allowing the Xiaomi M365 scooter to reach speeds of up to 30-32 km / h on a flat surface.

To install, you'll need an Android smartphone (on iOS, the process is more complicated and requires special adapters) and a Xiaomi Flasher app or the like. The process involves connecting to a scooter via Bluetooth, reading the current version of the BMS and controller, and then writing a new firmware file. It's important not to interrupt the process and keep the phone close to the deck.

Installation process:


1. Download APK firmware file Dash (version for M365 or Pro).




2. Launch the Flasher app.




3. Connect to the scooter.




4. Press Flash and wait for the process to end (about 2-3 minutes).




5. Reset the scooter.

Once you install Dash, you'll have new options in the scooter menu, you'll be able to adjust recovery, trigger sensitivity, and most importantly, speed modes. Some firmware versions allow you to switch between Pedestrian, Standard, and Sport modes with a triple tap on the power button.

⚠️ Note: Installing custom firmware permanently changes the digital signature of the device. You can go back to the original firmware, but this requires a backup (dump) of your original firmware made before installing Dash.

Comparison of stock and modified versions

To understand the difference between factory condition and tuning scooter, it is worth considering the technical parameters in comparison, the modification affects not only the maximum speed, but also the dynamics of acceleration, braking efficiency and available settings.

As you can see from the table, the modified version gives the user full control of the device. The ability to adjust the recovery is especially useful: you can make the braking of the engine softer for comfort or hard for quick stop. You can also start from a place without pushing the foot, which is convenient at traffic lights.

However, it is worth remembering that increased load on the motor-wheel and controller can lead to faster wear of components. When driving at maximum speed, the motor windings and the controller's power keys are warmed up. It is recommended to take breaks on long trips to let the equipment cool down.

Configuring the controller parameters

Once you have custom firmware, you can access the deep controller settings, you can change the engine settings through Dash or M365 Tools, and one of the key settings is Current Limit, which increases the thrust on the rises, but increases the risk of overheating.

Weakness is also available, allowing the motor to spin faster, sacrificing some of the torque at low speeds, which is important for maximum speeds, but in practice, for urban driving, standard values of modified firmware are sufficient.

• 🔋 Low Voltage Protect: Battery shutdown threshold. It is not recommended to lower it below 30V to avoid killing cells.
• ⚡ Regen Current: Braking currents, high values charge the battery faster, but make braking sharp.
• 🚀 Start Mode: Choice between Starting From a Shoot or Starting From a Place.
• 🌡️ Temp Limit: Motor shutdown temperature. 85-90 degrees, but with caution.

Experimenting with current settings should be extremely careful. Too high current can lead to failure. IGBT-If you are not sure of your actions, it is better to leave the factory values of currents that have already been optimized by Xiaomi engineers to balance power and reliability.

💡

The optimal setting for a city is to remove the speed limit without increasing the limit currents, and this gives you a boost without the risk of burning the electronics.

Technical risks and maintenance

The increase in the speed of the Xiaomi M365 scooter inevitably leads to changes in operating conditions, tires suffer first. At high speed, the risk of puncture is higher, and the tread wear is more intense. Tire pressure is recommended and keep it at 50-55 PSI (3.5-3.8 atm) for better roll-back.

The second critical element is the brake system: Stock brakes are designed to quench speeds of up to 25 km/h. At 32+ km/h, their effectiveness may not be enough for an emergency stop. Many enthusiasts install disc brakes instead of drum brakes or change the pads to better quality analogues.

⚠️ Attention: For long driving at maximum speed, monitor the temperature of the motor-wheel. If the deck of the scooter becomes hot to the touch near the axis of the wheel, slow down and let the engine cool down, otherwise it is possible to melt the insulation of the windings.

Also worth mentioning is vibrations. At high speeds, any backlashes in the structure (such as in a folding mechanism or wheel insides) become more noticeable and dangerous. Strip bolts regularly and check the condition of the bearings. Bearing lubrication should be carried out more often than in normal use.
