Control unit cloning
Module Cloning
We clone ECU, BCM, TCM and IMMO. All software, calibration and immobilizer data is transferred to a working donor unit — no dealer required.
What's included
- Complete data transfer to donor unit
- Immobiliser synchronisation always included
- VIN and OEM matching if required
- Plug & play — no extra programming needed
- 12-month warranty on completed work
Common clone jobs
Every module has its fingerprint.
Module cloning is rarely generic. The control unit type, generation and immobilizer architecture determine what data must move and which symptoms the driver experiences.
Body Electronics
VOLVO · CEM P2 / P3 / SPA
Volvo CEM
Volvo's central module across the P2, P3 and SPA platforms. Controls comfort functions, the CAN gateway and key system. Common faults: immobiliser activation, battery drain and intermittent electrical dropouts.

BMW · MINI · EWS / CAS1–4
BMW & Mini CAS
Covers all generations from EWS1–4 and CAS1–4. Manages key recognition, start authorisation and steering lock logic. Cloning requires synchronisation with the DME/DDE and instrument cluster.

FORD · BCM / GEM / BJB
Ford BCM & GEM
Shared control module across Ford platforms managing power distribution, ignition logic and multi-function systems. Cloning must correctly handle VIN binding and the immobiliser profile.

FIAT · CITROËN · PEUGEOT · BSI
BSI — Built-in Systems Interface
The master body module on PSA and Fiat platforms. Manages ignition, alarm, lighting and network communication. Requires pairing with keys and, where fitted, the audio system and display.

ECU · ENGINE CONTROL UNIT
Engine Control Unit (ECU)
The ECU governs fuel injection, ignition timing, turbocharger control and emissions management. Cloning preserves the VIN, OBD calibration and all learned adaptation values — regardless of make, supplier or generation.
Search ECU families
TCM · TRANSMISSION CONTROL
Transmission Control Unit (TCM)
The TCM manages shift points, torque limits and adaptive gear-change learning. Typical fault symptoms include harsh or missed shifts, gearbox emergency mode and P0700-family fault codes.

VOLVO · DIM · DRIVER INFORMATION MODULE
Volvo DIM
Driver Information Module on P2 and P3 platforms. Cloning transfers odometer, VIN, immobiliser binding, and configuration data to a functional used unit in case of pixel fade or total failure.

FORD · IPC · INSTRUMENT PANEL CLUSTER
Ford Focus IPC
Ford instrument panel stores odometer, VIN and immobiliser key data. In case of pixel loss or power failure, we clone all data to a new or used unit for plug & play operation.

MERCEDES-BENZ · IPC · INSTRUMENT CLUSTER
Mercedes Sprinter IPC
The Sprinter (W906 etc.) cluster stores mileage synced with the EZS/EIS. We perform cloning and pairing to restore mileage and VIN on a replacement unit without sync issues.

AUDI · IPC · VIRTUAL COCKPIT
Audi A6 IPC
Digital clusters (Virtual Cockpit etc.) are protected via Component Protection. Cloning transfers mileage, VIN and CS security keys directly to bypass dealer lock during swapping.

Three steps. No guesswork.
Diagnosis & read-out
We check communication on the bench where possible. For component-level cloning we visually inspect the donor unit — looking for signs of previous overheating, oxidation on connection points or damage to the circuit board before proceeding.
Donor match & cloning
The customer is responsible for sourcing the correct donor unit — OEM number, hardware revision and generation must match. If the unit is rare or hard to find, we can help identify the correct part before you order.
Test & return
We measure power draw and verify that the programming is correct. Communication is checked on the bench one final time before the unit is packed and returned. In-vehicle verification takes place when the unit is reinstalled by you or your workshop.
Unlocking & virginisation
Unlocked for installation in another vehicle.
Control units in modern vehicles are linked to the vehicle's immobiliser system and cannot be installed directly in another vehicle. We perform unlocking and virginisation so the unit can be paired to a new vehicle — without a donor vehicle.
Mercedes-Benz
Control units are paired to the vehicle's authorisation system (FBS). FBS3 can in most cases be unlocked via dump-based processing — FBS4 is cryptographically stronger and requires more advanced handling.
ECU · ME / CDI / PLD
ECU
The engine control unit is paired to the vehicle's authorisation system (FBS3/FBS4). We unlock the unit via dump-based processing and clear the pairing data — required before installation in another vehicle and reprogramming via Star Diagnosis.
EGS · VGS · TCU · 7G-TRONIC / FDCT
EGS / VGS
The gearbox module is bound to the FBS system and cannot be swapped directly with a second-hand unit. VGS2 and FDCT2 variants can be unlocked, removing existing pairing and enabling re-pairing to a new vehicle without donor data.
ISM · DSM · INTEGRATED STARTER
ISM / DSM
The ISM and DSM are hardware-bound to the vehicle's FBS key data and will block starting if installed in the wrong vehicle. Dump-based unlocking clears the active pairing and allows re-pairing with the receiving vehicle.
INSTRUMENT CLUSTER · DIM · IC177
Instrument Cluster
The instrument cluster stores odometer data, VIN and SSID and communicates with the EZS and SAM. We handle SSID repair and unit unlocking — required when swapping a second-hand cluster before re-pairing with a new vehicle.
AIRBAG · SRS · CRASH CONTROL UNIT
Airbag / SRS
When an airbag system has deployed, crash dumps and a VIN lock are stored in the SRS module. We clear crash dumps and repair the VIN binding — enabling reuse of the unit and a cost-effective alternative to purchasing a new SRS unit.
What customers say
Real results. Real customers.
“Sent in a Volvo CEM P3 that was completely dead after water damage. Got back a cloned unit that worked straight away — no dealer, no coding session. Done within two days.”
Marcus L.
Independent workshop, Gothenburg
“My BMW CAS3 had an immobiliser fault and the car would not start. OBD Tuning cloned a donor unit and synchronised it with my DME. The car starts fine now and the cost was a fraction of the dealer quote.”
Anna K.
Private customer, Stockholm
“I work with second-hand control units and regularly send units here for cloning and virginisation. Fast handling, clear communication on donor selection, and always a correct result. Highly recommended.”
Tobias R.
Vehicle technician, Malmö

Prices are indicative and apply to the cloning work itself. A final price is always confirmed once we have assessed the module type, hardware revision and fault pattern.
In many cases we hold used donor units in stock — we help you match the correct OEM number and hardware generation at no additional charge.
