Installation Instructions
The following steps outline the process for replacing the joystick modules. This procedure requires a professional tool kit, including a soldering iron, desoldering pump/wick, flux, and small screwdrivers (not included).
- Disassemble the Controller: Carefully open your PS5 DualSense or DualSense Edge controller. Refer to specific controller disassembly guides if unfamiliar with the process. Disconnect the battery and any ribbon cables.
- Locate Joystick Modules: Identify the existing joystick modules on the controller's circuit board.
- Desolder Old Modules: Using a soldering iron and desoldering tool (pump or wick), carefully desolder all pins connecting the old joystick modules to the circuit board. Ensure all solder is removed to prevent damage to the PCB pads.
- Remove Old Modules: Once all pins are desoldered, gently remove the old joystick modules from the circuit board.
- Prepare New Modules: Place the new GuliKit TMR Magnetic Joystick Modules into the vacant positions on the circuit board, ensuring correct orientation.
- Solder New Modules: Solder each pin of the new joystick modules to the circuit board. Ensure strong, clean solder joints without bridges.
- Reassemble Controller: Carefully reassemble your controller, reconnecting all cables and the battery.

Calibration
After installing the new TMR joystick modules, calibration is required to ensure optimal performance and accuracy. This step is crucial for eliminating any potential residual drift or incorrect input readings.
- Access Calibration Tool: Visit the official GuliKit website and locate their joystick calibration tool.
- Connect Controller: Connect your PS5 controller to a PC using a USB cable.
- Follow On-Screen Instructions: The calibration tool will guide you through the process, typically involving moving the joysticks through their full range of motion.
- Verify Calibration: After calibration, test the joysticks in a game or a controller testing utility to confirm proper functionality and absence of drift.
For Xbox Series controllers, calibration can be performed via the Xbox console settings or the "Xbox Accessories" software on PC.
Maintenance
The GuliKit TMR Magnetic Joysticks are designed for long-lasting, drift-free performance due to their contact-less nature. Minimal maintenance is required.
- Cleaning: Periodically clean the exterior of your controller and the base of the thumbsticks to prevent dust and debris accumulation.
- Thumbstick Caps: The included GuliKit KK Ring anti-friction stick caps can be easily replaced if they show signs of wear.

Troubleshooting
If you encounter issues after installation, consider the following troubleshooting steps:
- Joystick Not Responding/Incorrect Input:
- Ensure all solder joints are clean and secure. Re-solder any questionable connections.
- Verify that the joystick module is correctly seated on the PCB.
- Perform the calibration process again.
- Check for any damaged traces on the PCB during desoldering/soldering.
- Persistent Drift:
- Re-calibrate the joysticks using the GuliKit calibration tool.
- Ensure no physical obstructions are preventing the joystick from returning to its center position.
- Controller Not Powering On:
- Double-check all ribbon cable connections and the battery connection.
- Ensure no short circuits occurred during soldering.
If issues persist, contact GuliKit customer support for further assistance.
