Clone the original ECU onto a replacement

Engine ECU data, donor compatibility and immobiliser adaptation must be considered together. Indicate whether you need a clone of an available original or an alternative for a missing original.

Engine ECU cloning

Cloning requires suitable original data and compatible replacement hardware. A documented cloning method is a starting point, not confirmation that any two units can be paired. The required data and any further vehicle work depend on the exact ECU.

Check the replacement before buying

Provide the original and replacement part numbers, hardware identifiers, vehicle model, year and previous diagnosis. An identical housing or vehicle series alone does not establish compatibility.

Request an assessment

Original unit missing or unreadable?

Tell us whether the original ECU is available and whether communication is possible. Without suitable original data, a clone cannot be promised. We assess whether a different supported procedure is suitable.

What a clone transfers

Which original data can be transferred depends on the exact ECU, supported procedure and condition of the data. A clone is not a promise to copy every memory area. Protected or damaged data can limit or prevent the intended work.

Why the hardware number must match

Identify the part numbers, hardware and software versions of both units before buying a replacement. Similar labels or housings do not establish compatibility. The replacement software version may matter; whether it can be changed depends on the supported procedure.

Tricore processors in EDC17 and MED17

Access methods and protection differ between processor and ECU variants. Damage can prevent recovery of the required data. The processor designation alone does not prove that all data can be recovered or that they are irretrievably lost.

Current Bosch MD1/MG1 generation

MD1 and MG1 include different variants and software levels. A family name or list entry does not establish cloning support for an individual unit. We assess the available data, replacement hardware and possible alternatives for the specific case.
