ECU Repair & Cloning
Common symptoms for ECU repair and cloning
- No communication with the ECU on diagnostic scan
- ECU won't power on or respond at all
- Visible water damage or corrosion on the unit
- Donor ECU fitted but needs cloning to match the vehicle
- Repeated, unexplained faults pointing to the ECU itself
Our process
What we check before programming
STEP 01
Confirm the fault is ECU-side
Wiring, sensors and grounds are checked first, so we only commit to ECU-level work once it's the right call.
STEP 02
Remove and inspect on the bench
The unit is opened and inspected at board level for corrosion, damaged tracks or failed components.
STEP 03
Repair or clone
We repair the existing ECU where possible, or clone and transfer the required data across to a suitable donor unit. Postal ECU cloning is available across Ireland where supported.
STEP 04
Programme, refit and verify
The ECU is programmed, refitted and tested to confirm correct communication and operation before handover.

FAQ
Questions about ECU Repair & Cloning
Can a water-damaged ECU be repaired?
Often, yes — it depends on how much corrosion has affected the board and components. We inspect first and let you know honestly whether repair or replacement is the better option.
Is ECU cloning the same as remapping?
No. Cloning transfers the existing software and identity data to a replacement ECU so the vehicle runs as before. Remapping changes the tuning values within that software.
Will cloning affect my immobiliser?
Cloning is done specifically to keep the immobiliser and vehicle systems working together correctly. Any immobiliser-related issues are part of what we check before and after the job.
