ECU cloning
Copy supported configuration and vehicle data from an original unit to a verified compatible donor.

Replacement ECU? Check compatibility before buying.
A second-hand ECU usually needs more than the same-looking plug. We assess the original and donor units, the data available and the supported route before quoting cloning, programming or recovery.
Service availability and price confirmed for your exact vehicle or unit.

Cloning, programming or recovery?
Programming & setup
Some replacements require software, coding or vehicle-side adaptation rather than a complete clone. We confirm the scope first.
Failed flash recovery
Assessment after an interrupted write or corrupted software. Recovery depends on hardware condition and supported access.
A clear process
How it works
Send both labels
Provide clear original and donor ECU labels, registration or VIN, the fault history and diagnostic codes. Ask us before buying a replacement.
Confirm the data route
We check hardware/software compatibility, whether the original data can be read, and which functions the exact ECU supports. We explain any limitations before work.
Book and pack the units
Once accepted, label the units ORIGINAL and DONOR and include the job reference. Protect them separately in a rigid box with anti-static protection.
Transfer and verify
We perform the agreed read, transfer or programming and the checks available on the bench. Your handover identifies any coding, adaptations or vehicle tests still needed.
Before you book
Same part number is not always enough
Hardware revision, software family, engine, transmission and production changes can affect compatibility. Some security data cannot be transferred using the available route. We do not label every cloned unit plug and play.
If the original ECU is dead
No communication does not always mean no readable data, but severe damage can prevent recovery. We assess the unit first. If the necessary data is unavailable, an alternative programming route may be needed or the job may not be possible.
What to send
- Original ECU and proposed donor, clearly identified.
- Vehicle registration or VIN and owner/workshop contact.
- Fault report and details of any previous programming.
- Only send keys or other modules if we request them.
What comes back
The agreed unit or units, a work record and any remaining installation requirements. A bench verification does not prove the absence of vehicle wiring, power-supply or immobiliser faults.
Your questions answered
Will it start with my existing keys?
On a supported and compatible cloning route this may be possible. We confirm the required data and any extra adaptation before accepting the job. It is not guaranteed from a part number alone.
Can I buy the donor first?
Send both labels before purchasing. This reduces the risk of buying a unit that cannot be used for the supported replacement route.
Do you clone every ECU or TCU?
No. Availability is specific to the control unit, revision and readable data. Send the identification first; we check support before quoting.
Is this the same as repairing the ECU?
No. Cloning transfers supported data to another unit. A damaged donor, an unreadable original or an unresolved vehicle fault can require a different repair route.
Start with your vehicle or module details
Send clear label photos, the vehicle details and a short description of the problem. We confirm the appropriate service, price and next steps.
