Service overview

Supported ECU data transfer, with compatibility checked first.

Your Denso (Toyota / Lexus) ECU, cloned to your replacement unit. We transfer the data from your original Denso (Toyota / Lexus) engine ECU (Toyota and Lexus petrol, diesel and hybrid) to a compatible replacement ECU, so it works in your car with your immobiliser and coding.

What we do with your Denso (Toyota / Lexus)

  1. Check both labels – part number and hardware must match before you post anything.
  2. Back up the data from your original ECU.
  3. Transfer and verify the data on the bench.
  4. Return both ECUs with a written report, tracked.

Price for Denso (Toyota / Lexus)

£149.99 – includes the compatibility check, backup, transfer, report and tracked UK return. If the transfer cannot be done, you are refunded less a £20 bench check fee and both units are returned. No VAT added.

Rules for Denso (Toyota / Lexus)

  • Denso units vary widely; we confirm your exact part number is supported before you post.
  • Mark the units ORIGINAL and DONOR. The donor must be the same part number and in working condition.
  • A fault code or no-start alone does not prove the ECU is faulty – check supply, grounds and wiring first.
  • We do not remove immobilisers or change emissions equipment.

Questions

Repair, cloning or replacement – which do I need?

If your unit has a repairable fault, repair keeps your original and needs no programming. If it is damaged but readable, cloning to a matching used unit is usually cheapest. If it cannot be read or repaired, we quote a replacement with your data transferred where possible.

Will the car need coding after the work?

Not after a repair or a successful clone – the immobiliser and coding come from your original data. Some units need adaptations reset after fitting.

Does a fault code prove the unit is faulty?

No. Supply, earths, wiring, sensors and actuators can set the same codes. That is why every unit is tested first and you get a written report.

What if my unit is not faulty?

You pay only the bench test and receive the report to show your garage.

Do you remove immobilisers or emissions equipment?

No.

Not sure of the part number?
