Compatible data transfer for a plug-and-play replacement.
ECU and vehicle-module cloning can transfer supported flash, EEPROM, coding, calibration, VIN and immobiliser-related data from an original control unit to a verified compatible replacement. We check the vehicle, module manufacturer, part number, hardware and software references before choosing OBD, bench or boot programming.
Where a full clone is supported, the donor can be prepared as a plug-and-play replacement that retains the required vehicle-specific information. Some vehicles still require diagnostic fault clearing, adaptation, calibration or component-protection procedures after installation.

ABS & ESP module data transfer
Selected brake control modules can be cloned, coded or configured after exact hydraulic-unit and electronic-controller compatibility checks.
SRS airbag module cloning
Compatible replacement airbag controllers may require data transfer, VIN coding or programming after all physical restraint-system repairs are completed.
Instrument cluster & dashboard modules
Lawful replacement-cluster programming and supported data synchronisation after verified failure, repair or module replacement.
Other electronic control modules
Selected gateway, FRM, lighting, parking-brake, steering and comfort modules are assessed by part number, hardware, software and available original data.
Compatibility note: “Plug and play” applies only where a complete supported clone can be produced from readable original data and a compatible donor. Diagnostic setup or calibration may still be required on some vehicles.
Replacement ECU data transfer
ECU cloning that preserves supported vehicle data.
When an engine ECU is damaged or no longer communicates correctly, a compatible donor unit may require data from the original controller before it can operate with the vehicle. Depending on the ECU, cloning may involve flash memory, EEPROM, coding, calibration and immobiliser or security-related information.
Cloning is not possible for every controller or every type of failure. We confirm the ECU manufacturer, family, part number, hardware number, software identification, processor and available original data before approving the work.
ECU cloning and programming services
From replacement modules to damaged ECU recovery.
Professional programming tools use different access methods according to the controller. OBD works through the vehicle diagnostic connection; bench connects to the removed ECU without necessarily opening it; boot mode accesses the control unit at circuit-board level where supported.
ECU cloning
Supported data is read from the original ECU and transferred to a compatible donor so the replacement can retain the required vehicle-specific information.
Replacement ECU programming
A replacement controller may require software, coding, adaptations, immobiliser matching or configuration rather than a direct one-to-one clone.
EEPROM and flash transfer
Internal memory areas are handled according to the exact ECU architecture. A complete backup is retained where the read method permits it.
TCU and gearbox cloning
Selected automatic transmission controllers can be cloned or programmed after hardware, software and compatibility checks.
Bricked ECU recovery
Interrupted programming, corrupted software or loss of communication may be recoverable by bench or boot access, subject to ECU condition.
Immobiliser data transfer
Supported security and synchronisation data can be transferred or programmed so compatible modules communicate correctly with the vehicle.
Body and access module cloning
BCM, BSI, GEM, SAM, UCH, FRM, CAS & KVM cloning.
Replacement body and security controllers may require EEPROM or flash transfer, VIN and variant configuration, software programming, immobiliser synchronisation or authorised key data. Original and donor module labels must be checked before removal or shipping.
BCM cloning
Transfer supported body configuration, VIN, flash, EEPROM and security data to a verified compatible Body Control Module.
BSI cloning
Supported Peugeot, Citroën and DS BSI data transfer, virgin preparation, configuration and ECU or immobiliser matching.
GEM cloning
Ford Generic Electronic Module replacement setup and supported original-data transfer for compatible hardware and software versions.
SAM cloning & programming

UCH cloning
Renault UCH body and security data transfer, coding and authorised synchronisation for supported donor modules.
FRM cloning & recovery
BMW and MINI Footwell Module coding, software recovery and supported data transfer following failure or replacement.
CAS cloning & ISN service

KVM cloning & programming
Jaguar Land Rover Keyless Vehicle Module replacement programming and authorised security-data transfer where compatible.
Professional programming methods
OBD, bench and boot-mode ECU programming.
The safest suitable method is selected from the controller protocol, condition and required operation. Stable voltage and verified connections are essential during every read and write.
In-vehicle programming
Reading, programming, coding or adaptation through the diagnostic port where the vehicle and controller support the required operation.
Connector-level access
The ECU is removed and connected directly on a controlled bench, commonly without opening the housing where the protocol supports it.
Circuit-board access
Direct processor-level access may support full backups, recovery or protected controllers, but requires specialist handling of the opened ECU.

Important ECU cloning conditions
What ECU Cloning Covers
ECU cloning transfers supported data to a compatible donor/replacement module. A cloning-only service does not provide an SGTM commercial warranty on customer-supplied ECU hardware, nor on unrelated mechanical or electrical faults in the vehicle. If SGTM supplies the replacement ECU/module, the selected parts option carries a 3-month commercial warranty for used/reconditioned parts or a 12-month commercial warranty for new parts, subject to the full warranty conditions and statutory rights.

Frequently asked questions
Does ECU cloning include a warranty on the original or donor ECU hardware?
A cloning-only service covers the agreed programming/data-transfer work, not the physical condition or remaining life of customer-supplied ECU hardware. Mechanical and electrical vehicle faults are also outside the cloning scope. If SGTM supplies the replacement ECU/module, the applicable SGTM commercial parts warranty is 3 months for used/reconditioned parts or 12 months for new parts, subject to the full Terms & Conditions and statutory rights.
What information is copied during ECU cloning?
Depending on the controller, a clone may transfer supported flash, EEPROM, calibration, coding and immobiliser-related data. Some ECUs require programming or adaptation instead of a direct clone, so the exact hardware and software references must be checked first.
Will the cloned ECU, TCM or BCM be plug and play?
Where the original data is readable and the donor is fully compatible, a complete clone can often be prepared as a plug-and-play replacement. Some vehicles still require fault clearing, adaptation, calibration, coding or component-protection procedures after installation. We confirm the expected fitting process before proceeding.
Does the replacement ECU need the same part number?
The safest donor is normally an exact or officially compatible hardware and software version. Similar-looking ECUs are not automatically interchangeable. Send clear label photographs of both units before purchasing or posting a donor.
Can you clone an ECU if the original is completely dead?
Possibly, but not always. Bench or boot access may recover data from some non-communicating units. Physical processor, memory, water or fire damage can make the original data unreadable, in which case another replacement and programming route may be required.
Is mobile ECU cloning available in Birmingham and the West Midlands?
Mobile service may be available for technically suitable vehicles in Birmingham, Stourbridge, Dudley, Halesowen, Wolverhampton, Walsall, Solihull and surrounding areas. ECU opening, circuit-board repair or controlled boot work may require workshop or postal service.
Can I send an ECU by post from Ireland, Scotland, Wales or Europe?
Yes, approved modules can be sent from across the UK, Republic of Ireland and Europe. Worldwide enquiries are also accepted. Contact us before shipping with the VIN, engine code and clear photographs of the original and donor ECU labels so compatibility, address, courier and customs requirements can be confirmed.
How should I package an ECU for postal programming?
Protect the module from static, moisture and impact; cover the connector pins, wrap original and donor units separately, and use a strong outer box with sufficient padding. Use tracked and appropriately insured delivery and retain the tracking number.
