The ECU cloning process involves copying software and data from one engine control unit (ECU) to another. The steps include:
Reading the original ECU – Connect the original ECU to a diagnostic scanner to read its software and data.
Saving the original ECU data – Dumping the ECU software and data to a storage device.
Preparing the replacement ECU – Erasing the existing data from the replacement ECU and making any necessary modifications.
Writing data to the replacement ECU – Transferring data from the original ECU to the replacement unit, known as “flashing.”
Verifying the replacement ECU – Checking the replacement ECU with a diagnostic scanner to ensure it matches the data from the original.
Installing the replacement ECU – Installing the replacement ECU into the vehicle, connecting it to the engine management system and verifying proper operation.
