Lishui Controller Programming !link! 〈SIMPLE ✯〉

Once you've mastered the basics of Lishui controller programming, you can explore advanced techniques to optimize the system's performance. Some advanced techniques include:

Hit "Program (F5)". If the process stops, you may need to briefly toggle the battery power (the "Door" wire) to trigger the bootloader.

Open the Lishui Tool and ensure the correct COM port is recognized. lishui controller programming

Provide:

The official tool is often the FPS2 USB Stick , which includes a voltage boost to power the controller’s logic board during the flash process without needing the main battery connected. Once you've mastered the basics of Lishui controller

Never connect or disconnect programming cables while the controller is powered on. High voltage can damage your USB adapter or PC.

| Parameter | What it does | Typical range | |-----------|--------------|----------------| | | LVC cut-off | 24V/36V/48V/52V/60V | | Current limit | Max battery Amps | 10A – 35A (safe for controller) | | Phase current | Motor torque limit | 40A – 80A | | Speed limit | RPM or wheel speed | 25 km/h – 70+ | | Throttle mode | Voltage start (0.8-4.2V) | Hall / Resistive | | PAS levels | Pedal assist sensitivity | 1–5 or 1–9 | | Regen braking | Strength & activation | Low/Med/High | | Low voltage cutoff | Protects battery | 1.0V – 1.5V below nominal | Open the Lishui Tool and ensure the correct

| Symptom | Likely cause | Fix | |---------|--------------|-----| | Can’t read/write | Wrong TX/RX or locked firmware | Swap wires; try password 1234 or 0000 | | Motor jerky | Phase/hall mismatch | Re-tune hall angle (30°, 60°, 120°) | | Speed limited to 25 km/h | Hard speed limit locked | Some cannot be changed – need unlocked firmware | | Overheating | Current too high for controller | Reduce battery/phase current 10-20% |

Parameters reset after power-off.

Remember: start small, log every change, and prioritize safety over speed. The road to advanced PEV tuning begins with understanding the brain—the Lishui controller.
