YOUR OPTIMIZED FILE IN 3 STEPS

  • Schritt 1
    First, read your ECU file using your preferred chiptuning hardware. Use professional tools such as MPPS, KESS, KTM, Galletto, or other common interfaces. Make sure the extracted file is complete and unmodified. Save the original file securely on your computer, as you will need it for the upload process.
    Step 1
    Step 1
  • Schritt 2
