ECU and ECM replacement
Supported engine-control modules can be reviewed for data transfer or cloning. The original module's condition and ability to read the required data are important; a damaged or unreadable unit may limit the options.

ECU & Automotive Module Cloning
Module cloning transfers supported data from an original control module to a compatible replacement. It can help preserve vehicle-specific information when replacing a failed ECU, ECM, BCM or other supported module.
- Original and replacement module identification is checked before work is accepted.
- Available data, hardware and software compatibility determine whether cloning is possible.
- Local service or Canada-wide mail-in handling is confirmed for the exact job before shipment.
When module cloning may help
A replacement module may need information held in the original unit, such as configuration or other vehicle-specific data. A used module with a similar label is not automatically a suitable replacement. We review the original fault, both part numbers and the intended replacement before recommending data transfer, programming or repair.
BCM and other modules
Body-control and other data-dependent modules are assessed individually. Hardware revisions, software and vehicle systems can affect compatibility even when the units look alike.
Cloning versus programming
Cloning copies supported original data; programming or configuration may follow a different process. Some jobs still require vehicle-side setup, keys or related modules. We confirm what is included and what remains to be done.
Information for a compatibility review
- Vehicle year, make, model and VIN
- Original and replacement module part numbers
- Clear photographs of both module labels and connectors
- The fault, diagnostic codes and previous programming attempts
- Whether the original module communicates and is available
- Any relevant replacement history or vehicle modifications
Repair and tuning are separate service paths
If the original module may be repairable, start with Automotive Electronics Repair. For supported tuning access, see BMW, MINI & Supra ECU Unlocking / Tuning. A tuning unlock is not the same service as replacement-module cloning.
Start with a service request
Tell us what needs attention and include the available identification and symptom details. We will review the request and confirm the next step before you send equipment.
Missing injector or ignition output?
If a module is still communicating but one injector or ignition-coil circuit is not being switched, read the ECM output-driver technical note before choosing repair or replacement-module cloning.
