Getting Started Without an EK1 Device (Pro, Lite, Mini)

Step 1: Purchase an EK1 Device

Step 2: Create an Account on SXTHNKTuning.com

Register on www.sxthnktuning.com and add your VIN and device serial number to your account information.

Step 3: Update Your Device Firmware

Ensure your device is running the latest firmware version.

Step 4: Find Your ECU's Calibration ID

1. Plug the device into your vehicle's OBDII port (left side of the steering wheel under the dash).
2. Choose "Power Mode".
3. Select "Read ECU ID".
4. Select "SIM2K-250".

5. Copy the values under Application Data ID into your account.

   i.e., JSNKKM__R1B

Important: Ensure accurate entry of your calibration ID with only two underscores ('__'). Incorrect ID entry can lead to ECU damage.

Step 5: Patch Your Vehicle's ECU

Download the Patch

• Go to the 'Patch' section on the SXTHNK platform.
• Copy and paste your calibration ID into the search box on the ECU Patch Files page.
• Download the patch file.
• Copy and paste the patch file to the Maps Folder of the SD Card.
