How the Unlock Process Works

1. Prepare and Package the ECU
   • Remove the ECU from the vehicle according to proper procedures.
   • Pack it securely with ample padding; the ECU must be well protected.
   • We do not accept any ECU that has been previously opened.
2. Ship to AMT TuningShip your ECU to:AMT Tuning Ltd

   • All shipping costs, including any import tax, are the sender’s responsibility
3. Unlock & Inspection
   • Our team physically opens and unlocks the ECU using professional tooling.
   • The ECU is thoroughly inspected for tampering:
     • We do not accept ECUs previously opened or modified.
     • If any non-authorized UART/CAN/FlexRay bus analyzers or devices are detected, the ECU will not be unlocked and no refund is possible (fraud detection policy).
4. Tuning & Programming
   • Once unlocked, we program the requested Stage 1, Stage 2, or custom calibration matched to your hardware.
   • Bench programming and calibration usually take 3–4 hours once the ECU is in our queue.
   • Typical unlock turnaround is about 1–2 weeks, but please allow up to 3 weeks depending on workload and shipping times.
5. Return Shipping & Reinstallation
   • The ECU is re-sealed, tested, and shipped back via the agreed carrier.
