McLaren ECU Clone Service
McLaren ECU / ECM / PCM cloning at the chip level on the bench. We read the original McLaren 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 McLaren 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 and hardware revision before you order and ship.
Compatibility Warning
ECU cloning works between a failed original and a compatible donor of the same generation, part number family, and hardware revision. Different generations are not cross-compatible. Always send label photos before ordering so we can confirm the donor matches.
