How it works

  1. 01 Read your unit

    Read the original file with your tool, over OBD, on the bench or via boot. Keep that read: it is your way back if anything goes wrong, and several checksums are calculated from it.

    with your tool
  2. 02 Upload it here

    Upload it with your unit's calibration number. Card and Mercado Pago clear instantly; bank transfer has no surcharge and the system enables it on its own.

    instant
  3. 03 We prepare it

    If we already have it done, it comes out right away. If the system solves it, up to 5 minutes. If it goes custom, up to 24 working hours. And it comes with the checksum corrected.

    from instant to 24 h
  4. 04 Write the unit

    With the same tool and the same method you read it with. Charger on: a voltage drop halfway through the write leaves the unit mute.

  5. 05 Test it on the car

    Drive it, watch the live values and check no warning light stays on. You get 3 downloads over 7 days, and your original read stays saved.
