Mazda ECU Clone Service

Mazda ECU cloning at the chip level on the bench. We read the original ECU Flash and EEPROM and write every byte onto a compatible donor of the same hardware family — including VIN, immobilizer pairing data, and customer parameters where readable.

Not Sure Which Service to Choose?

If you are unsure which option matches your Mazda module, the safest path is to email or text us photos before ordering: full label of the original module, full label of the donor module if you already have one, the part number, hardware revision, and software/calibration sticker. We will confirm whether the service is supported for your specific part number before you order and ship.

Compatibility Warning

Cloning requires a donor ECU of the same hardware family — same part number prefix, same processor, same hardware revision. Mismatched donors will not clone successfully.

What to Ship

• Your original Mazda module (the failed/locked unit), clearly marked “ORIGINAL”
• If applicable: a donor module, clearly marked “DONOR” — same part number family and hardware revision as the original
• Your order receipt printed, or order number written on a slip in the box
• Your return shipping address
• Ship to the address shown on your order receipt at checkout

FAQ

What does the clone preserve? Flash and EEPROM copied 1:1 — including VIN, immobilizer pairing data, customer parameters, and any aftermarket tune overlay where readable.

How long does it take? Most clones are completed within 1 to 3 business days of receiving both modules.
