Open your controller case. Look for a 4-pin header labeled:

Some models use a 6-pin JST connector. If unlabeled, trace the pins back to the MCU. Pins PB13 (SWCLK) and PB14 (SWDIO) are common on STM32F103 chips.

Checklist before programming:

Lishui controller programming is a powerful skill that turns a generic, restricted electric scooter into a personalized performance machine. With a $10 ST-Link dongle, a bit of patience, and the guidance above, you can adjust speeds, currents, and throttle feel to your exact liking.

However, respect the hardware. The engineers at Lishui set limits for a reason: thermal dissipation, MOSFET safe operating area (SOA), and battery C-rating. Incremental changes (10–20% over stock) are usually safe. Doubling currents is a recipe for smoke.

If you are a beginner, start by backing up your firmware and simply adjusting the throttle curve or reducing the regenerative braking strength. As you gain experience, move on to speed derestriction and battery upgrades.

The world of PEV modding is exciting, but it begins with understanding the brain of your vehicle. Happy programming—and ride safely.

    Lishui controllers are widely used in ebikes and can be programmed through two primary methods: standard parameter adjustment via the display and deeper firmware flashing using dedicated hardware. 1. Standard Parameter Adjustments (Display)

    Most Lishui-based ebikes (like those using SW900 or KT-LCD displays) allow you to modify basic performance settings through a built-in menu. Common parameters include:

    P01–P03: Screen brightness, units (km/h vs. mph), and battery voltage (24V, 36V, 48V, etc.).

    P06–P08: Wheel diameter, motor magnet count, and the maximum speed limit. P13: Controller amperage setting to adjust power output. 2. Firmware Programming (Advanced)

    For deeper customization (e.g., Field Oriented Control (FOC) tuning or current limits), you must flash the controller directly using a computer.

    Official Tools: Lishui provides a "LSH Programmer" tool and specific .lsh encrypted firmware files. To use these, you typically need a Lishui-specific USB programming stick (FPS2) or a compatible USB-to-UART adapter connected to the display cable's RX/TX pins.

    Open Source Alternatives: Projects like EBiCS_Firmware and the Flexible OpenSource Firmware allow you to bypass factory restrictions. These often require an ST-Link V2 programmer to connect directly to the controller’s internal STM32 pins.

    Custom Settings: By unchecking "Keep Current Settings" in official Lishui tools, you can sometimes manually set new maximum current and low-voltage cutoff values. 3. Necessary Hardware Connection Point Display Buttons Handlebar Display Basic speed and PAS level limits. USB-to-UART Adapter Display Connector Parameter adjustment and .lsh firmware updates. ST-Link V2 Internal PCB Pins Complete open-source firmware replacement.

    Safety Warning: Always use a fuse in your power supply when flashing firmware to prevent permanent damage to the controller or battery if a short circuit occurs.

    Programming a Lishui e-bike controller allows you to unlock higher speeds, adjust current limits, and customize the riding feel through field-oriented control (FOC) or torque simulation

    . While stock programming is often restricted by manufacturers, there are three primary ways to modify these controllers depending on your technical comfort level. 1. Official Manufacturer Tools (Basic Configuration) If you have a

    firmware file provided by a tech team or found online, you can use official software to update parameters like max current and undervoltage limits. : Download the LSH_File_Update_Tools LS_Controller_Update.exe from the official Lishui Controller Download Page

    : You typically need a Lishui-specific USB programmer (like the The "Secret" Menu

    : In some versions of the programmer, clicking "Clear Info" multiple times reveals a "File Conversion" tab used to convert hex files to

    : Connect the programmer to the controller's display connector (RX to TX, TX to RX). You may need to power the controller via the e-bike battery during the process if the USB port doesn't provide enough current. 2. Open Source Firmware (Advanced Customization) For users wanting total control, the EBiCS (E-Bike Controller System)

    project provides a free FOC firmware for Lishui controllers that use the STM32F103 processor. Key Features

    : Supports sinewave driving, throttle, torque-simulation, and torque sensors. Flashing Method : Requires an ST-Link V2

    programmer. For newer controllers, you may need to open the housing and solder wires to the GND, +3.3V, SWDIO, and SWCLK pins. Source Code : Available on the EBiCS GitHub Repository 3. Display-Based Adjustments (Quick Settings)

    If you aren't ready to flash new firmware, many Lishui controllers support "P-settings" through the LCD display (like the : Speed Limit (0–100 km/h).

    : Current Limit (set to match your controller's amp rating).

    : Some manufacturers lock these settings at the factory, in which case flashing (Option 1 or 2) is the only way to override them. Warning: Safety First

    Lishui controllers (LS), manufactured by the Nanjing Lishui Electronics Research Institute, are widely used in e-bikes for their smooth Field-Oriented Control (FOC) performance. Programming these units allows riders to fine-tune torque delivery, adjust current limits, and even install custom open-source firmware. Essential Programming Tools

    To interface with a Lishui controller, you need specific hardware to bridge the gap between your computer and the controller’s display or programming port:

    USB-to-Serial Adapter: A standard FT232RL-based adapter is the industry standard for stable communication.

    Programming Cable: Depending on your controller model, you may need a Julet 5-pin or 4-pin waterproof connector cable that breaks out into RX, TX, GND, and VCC.

    ST-Link V2 (Optional): Required for flashing deep firmware or unbricking controllers that do not have a bootloader accessible via the display port. The Official Programming Process

    Official programming is typically done using the Lishui LSH_File_Update_Tools. This utility allows you to upload .lsh firmware files provided by manufacturers or tech teams.

    Driver Setup: Install the appropriate USB serial drivers. If the software shows a COM port number, the connection is successful.

    Connection: Connect the adapter to the controller's display port. Most modern controllers can be "self-powered" by the USB port, but older versions require the e-bike battery to be connected and switched on during the process.

    Loading Firmware: Use the "Local File" button to load your .lsh file.

    Adjusting Basic Settings: By unchecking the "Keep Current Settings" box, users can often manually adjust the maximum current and undervoltage cutoff limits before flashing.

    Flashing: Press Program (F5) and wait for the "Write successful" confirmation. Third-Party & Open-Source Options

    For advanced users, the official software can be restrictive. Several community-driven alternatives exist:

    EggRider V2 Display: A popular aftermarket display that allows you to configure Lishui settings directly from a smartphone app via Bluetooth.

    EBiCS Open Source Firmware: A community project on GitHub that provides free FOC firmware for Lishui controllers, offering features like regenerative braking and customized torque sensing.

    XPD (Extended Parameter Designer): Older software used for some sine wave controllers to adjust ramp times and PAS (Pedal Assist) sensitivity. I have a Lishui Controller .lsh firmware file lets mod it

    PAS type (left/right mounting), number of magnets, and assist pulse delay. Riding Strategy

    Selection between "Normal" or "Current Simulation" modes to change how power is delivered. Hardware Requirements Program Downloader

    Lishui controllers are typically "OEM-locked," meaning they are programmed at the factory for specific bike models and aren't as easily customizable as KT (Kunteng) controllers. However, you can modify them using specialized hardware, manufacturer tools, or community-developed open-source firmware. 🛠️ Programming Methods 1. Official Lishui Programming Tool

    This is the standard "manufacturer" way to update firmware or change basic limits.

    Hardware Needed: You require a specific Lishui USB Stick FPS2 and matching adapter cables.

    Software: The Lishui Controller LSH Programmer allows you to upload .lsh firmware files and adjust max current or undervoltage limits.

    Limitation: These tools are difficult for individual consumers to find and are mostly sold to retailers or manufacturers. 2. Open Source Firmware (OSF)

    The CloneYCRS project on GitHub is the most popular way to "unlock" these controllers.

    What it does: Replaces the factory software with Field Oriented Control (FOC) firmware that is fully customizable.

    Features: Includes a user-friendly GUI to adjust throttle response, torque simulation, and sensor settings.

    Hardware: You typically need an ST-Link V2 programmer to flash the firmware directly to the controller's internal chip. 3. Display-Based "Hidden" Menus

    For minor adjustments like speed limits or wheel size, you can sometimes use the LCD display.

    Access: On many models, holding the Up and Down arrows simultaneously enters the settings mode.

    Parameters: Settings are often unlabelled (e.g., #1 to #20). For example, setting #18 often adjusts the speed reading/limit between 50% and 150%. ⚠️ Key Challenges

    Potting Material: Many Lishui controllers are filled with a thick "glue" or wax-like potting to protect against water, which can make accessing the internal pins for a programmer nearly impossible.

    Hardware Variants: Different models use different processors (like the STM32 series). You must verify your specific chip before trying to flash custom firmware to avoid "bricking" the unit.

    Baud Rate: If using a PC tool, the default baud rate is typically 38400. If you'd like to proceed, let me know: Your controller model number (e.g., LSW1207)

    What specific change you want to make (e.g., increase speed, change PAS levels)

    If you are comfortable with soldering or using an ST-Link device

    I can then provide a more specific step-by-step guide for your setup.

    Lishui controllers are typically "OEM-locked," meaning they are programmed at the factory for specific bike models and aren't as easily customizable as KT (Kunteng) controllers. However, you can modify them using specialized hardware, manufacturer tools, or community-developed open-source firmware. 🛠️ Programming Methods 1. Official Lishui Programming Tool

    This is the standard "manufacturer" way to update firmware or change basic limits.

    Hardware Needed: You require a specific Lishui USB Stick FPS2 and matching adapter cables.

    Software: The Lishui Controller LSH Programmer allows you to upload .lsh firmware files and adjust max current or undervoltage limits.

    Limitation: These tools are difficult for individual consumers to find and are mostly sold to retailers or manufacturers. 2. Open Source Firmware (OSF)

    The CloneYCRS project on GitHub is the most popular way to "unlock" these controllers.

    What it does: Replaces the factory software with Field Oriented Control (FOC) firmware that is fully customizable. Open your controller case

    Features: Includes a user-friendly GUI to adjust throttle response, torque simulation, and sensor settings.

    Hardware: You typically need an ST-Link V2 programmer to flash the firmware directly to the controller's internal chip. 3. Display-Based "Hidden" Menus

    For minor adjustments like speed limits or wheel size, you can sometimes use the LCD display.

    Access: On many models, holding the Up and Down arrows simultaneously enters the settings mode.

    Parameters: Settings are often unlabelled (e.g., #1 to #20). For example, setting #18 often adjusts the speed reading/limit between 50% and 150%. ⚠️ Key Challenges

    Potting Material: Many Lishui controllers are filled with a thick "glue" or wax-like potting to protect against water, which can make accessing the internal pins for a programmer nearly impossible.

    Hardware Variants: Different models use different processors (like the STM32 series). You must verify your specific chip before trying to flash custom firmware to avoid "bricking" the unit.

    Baud Rate: If using a PC tool, the default baud rate is typically 38400. If you'd like to proceed, let me know: Your controller model number (e.g., LSW1207)

    What specific change you want to make (e.g., increase speed, change PAS levels)

    If you are comfortable with soldering or using an ST-Link device
