ECU clone & decode
1:1 ECU cloning, decoding and IMMO OFF — by post
Avoid dealer programming. We clone your original ECU data — including keys, mileage and immobiliser sync — onto a donor unit, so the replacement plugs straight in.
Who it is for
- •Garages avoiding main-dealer security charges
- •Trade customers needing fast IMMO OFF turnarounds
- •Vehicle owners with damaged but readable ECUs
Turnaround
1–3 working days from receipt for cloning. IMMO OFF files typically returned same day.
Lifetime warranty on repairs
What we need
- •ECU part number on both units (must match)
- •Vehicle make, model, year and VIN
- •Whether you require IMMO retention or full IMMO OFF
- •Trade customers: account email for invoicing
How to send your unit
- 1
Send your original ECU plus the donor unit (if you have one).
- 2
Include the cover sheet with vehicle details and required service.
- 3
We read both units, clone the data and verify before return.
- 4
Plug the cloned unit straight into the vehicle — no programming required.
