01
What 1:1 cloning means
We read EEPROM, flash and internal data of the original unit and write them onto an identical unit.
The cloned unit behaves like the original: same VIN, same key, same learned values.
The car starts without immobiliser sync or a dealer appointment.
02
Engine control unit (ECU)
We clone ECUs with hardware faults, water corrosion or overvoltage damage.
Immobiliser data, injector corrections and learned values are preserved.
Depending on the platform we work on the bench or via OBD with professional equipment.
03
Gearbox control unit (TCU)
In automatic gearboxes the TCU stores clutch and pressure adaptations that cannot be invented.
Cloning keeps those values and avoids harsh shifts or relearning from zero.
The right route when the electronics fail but the gearbox itself is healthy.
04
Process and documentation
Diagnosis first, then a full read and backup before anything is written.
Verification on the car or on the bench, fault memory check and function test.
Documented handover — if anything is unclear we call before continuing.
05
Repair instead of replacement
When the board is recoverable we repair the original unit instead of cloning it.
Repair and cloning are alternatives to a new part — usually faster and cheaper.
We decide with the diagnosis in hand, not from a catalogue.
