This guide is specifically for vehicles equipped with SIM2K-250 and SIM2K-260 ECUs. Patching is a crucial step before tuning these vehicles and is required only once.

1. Find Your Calibration ID:
   • Follow the steps outlined in the guide to find your ECU's calibration ID.
2. Download the Patch:
   • Go to the 'Patch' area on the SXTHNK platform.
   • Look for a patch that exactly matches your calibration ID.
   • If you do not find a matching patch, submit a ticket for assistance.
3. Flashing the Patch:
   • Follow the same steps as in the tuning guide to prepare your vehicle and EK1 device.
   • When prompted, select the 'BootPatch' file instead of a tune file.
   • Complete the patching process without interruption.
4. Post-Patching Steps:
   • Once the patch is successfully applied, you can flash tunes freely on your vehicle.

Important Notes:

• Patching is a longer process than regular tuning, so ensure your vehicle's battery is adequately charged or connected to a charger.
• The patching process is a one-time requirement and allows for subsequent tune flashes without restrictions.
