ECU/TCU/BCM Cloning

Got a shock when the dealer told you the price for a new ECU/TCU/BCM?

Modern automotive computer systems are not simple things to replace, with security keys, handshakes, parametrization and coding. If you need to replace a damaged ECU/TCU/BCM our cloning services may be just what you need.

Description

Modern vehicles rely on electronic control modules to manage critical functions such as engine performance, transmission behavior, and body control features. When these modules fail, replacement units must be programmed correctly to match the vehicle’s existing system. Our ECU, TCU, and BCM Cloning Service provides a cost-effective solution by transferring all necessary data from the original module to a compatible replacement, ensuring seamless operation without the need for expensive dealer programming.

What's Included in our services portfolio:

ECU (Engine Control Unit) Cloning – Transfers vital engine management data, immobilizer settings, and VIN information to a new or used ECU.

TCU (Transmission Control Unit) Cloning – Ensures proper shifting and communication by copying transmission parameters and security data.

BCM (Body Control Module) Cloning – Retains all vehicle settings, including lighting, central locking, and security functions.

EEPROM & Flash Data Transfer – Copies all critical memory sectors, including immobilizer codes, sensor calibrations, and adaptations.

Checksum Correction & VIN Programming – Ensures the replacement module is recognized and functions correctly in your vehicle.

Bench or On-Vehicle Cloning – Depending on the module and vehicle, we offer cloning on our workbench or directly in the vehicle.

Testing & Verification – We verify the cloned module’s functionality to ensure a perfect match before installation.

How Our ECU/TCU/BCM Cloning Service Works

When you call us with an ECU, TCU, or BCM issue, here’s exactly what happens:

Value Adds:

1. Module Identification & Assessment

🔹 Determine the Module Type – Identify whether the unit is an ECU, TCU, or BCM and verify its make, model, and part number.
🔹 Assess the Original Module – Check for physical damage, water intrusion, burnt components, or corrupted data.
🔹 Verify the Replacement Module – Ensure the replacement module is compatible with the vehicle in terms of hardware and software version.

Step 2: Reading Data from the Original Module

🔹 Connect to the Module – The original module is connected to a specialized programmer via OBD, bench mode, or boot mode (direct chip access).
🔹 Extract EEPROM & Flash Data – Read and back up the vital data stored in the module, including:

VIN (Vehicle Identification Number)
Immobilizer & Security Data
Engine/Transmission Configuration
Calibration & Adaptation Values

🔹 Verify Data Integrity – Check the extracted files to ensure they are not corrupted or incomplete.

Step 3: Writing Data to the Replacement Module

🔹 Prepare the Replacement Module – Some modules require unlocking or resetting before programming.
🔹 Transfer EEPROM & Flash Data – Write the saved data from the original module onto the replacement unit.
🔹 Checksum Correction & VIN Matching – Ensure the replacement module’s software is properly aligned with the vehicle’s configuration.
🔹 Adaptation for Immobilizer & Security System – If necessary, sync the module with the vehicle’s immobilizer to prevent key programming issues.

Step 4: Testing & Verification

🔹 Bench Testing (If Applicable) – Before installation, some modules can be tested on a bench setup to confirm communication.
🔹 Install the Cloned Module in the Vehicle – Connect the replacement module and power up the vehicle.
🔹 Check for Fault Codes – Scan the vehicle with a diagnostic tool to ensure the new module is recognized and there are no errors.
🔹 Perform Functionality Tests – Verify engine start, transmission shifting, lighting, central locking, or other relevant module functions.
🔹 Drive Test (For ECU/TCU) – In cases of engine or transmission modules, a road test may be necessary to confirm proper operation.

Step 5: Finalization & Support

🔹 Provide Backup Files – Save a copy of the original module’s data for future reference if needed.
🔹 Customer Support – Offer guidance on installation or post-installation troubleshooting.
🔹 Optional Customization – If requested, performance tuning or coding modifications can be applied.
