Caterpillar ECU Clone Service
Caterpillar ECU / ECM / PCM cloning at the chip level on the bench. We read the original Caterpillar engine control unit 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. Cloning is the most common alternative to dealer ECU replacement when the original module has failed but is still readable.

Not Sure Which Service to Choose?
If you are unsure which option matches your Caterpillar 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. Send us photos of both module labels (original and donor) before purchasing the donor to confirm compatibility.
What to Ship
- Your original Caterpillar ECU (the failed/locked unit), clearly marked “ORIGINAL”
- A donor ECU of the same hardware family, clearly marked “DONOR”
- 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 overlay where readable.
Do I need to ship both modules? Yes — original plus donor of the same hardware family.
Will my keys still work after the clone? In most clone services we transfer supported VIN and immobilizer data when readable, so existing keys typically continue to work.
How long does it take? Most clones are completed within 1 to 3 business days of receiving both modules.
