File service

Send a read, get a calibration back

No database lookups and no waiting on a queue you cannot see. Here is exactly what happens to a file once you send it.

The process // 01

From upload to download

STEP 01

Send the read

Upload the original file through the portal, or email it over. Tell us the vehicle, the tool you read it with and what you want from it.

STEP 02

We check it first

Every file is opened and checked before anything is written. If the read is incomplete or the vehicle is not a good candidate, you hear from us rather than getting a file back that does not work.

STEP 03

Written and tested

An engineer writes the calibration by hand against the maps in that ECU, then it goes through our own checks before it leaves.

STEP 04

Download and log it

The finished file lands back on your account, usually inside the hour. Log the car afterwards and send it over if you want anything adjusted.

What you get // 02

Included with every file

The price covers the work, not just the download. If the car needs the file moving after a log, that is part of the job rather than another line on the invoice.

  • Your original is keptEvery read you send is stored against your account, so the vehicle can be returned to factory software years later.
  • Revisions are freeIf the car needs the file adjusting after a log, send it back. We do not charge per revision.
  • Written by a personThere is no database picking a file for you. An engineer opens the maps for that exact ECU and writes it.
  • Support that answersMessage us during opening hours and you get a person who knows the file, not a ticket number.

Turnaround // 03

Questions // 05

Before you send the first one

What do you need from me?

The original read, the vehicle details and the tool you used. If you can tell us what the customer is after and anything that has been changed on the car, the file comes back closer first time.

How quickly do files come back?

Most common platforms are 20 to 40 minutes inside opening hours. Anything unusual we will tell you about up front rather than leaving you waiting.

What if the file is not right?

Send us a log and we will revise it. Revisions are included, and there is no limit on them while you are getting the car where you want it.

Do you support slave tools?

Yes, slave and master. If your tool encodes the file, tell us which one it is when you send it and we will handle it.

Can I get my original back later?

Yes. Every read you send stays on your account, so you can put a vehicle back to factory software whenever you need to.

Do you write emissions delete files for road cars?

No. Removing or disabling DPF, EGR or AdBlue equipment on a road registered vehicle is an offence in the UK and most of Europe, and it fails an MOT. We diagnose those systems and help you fix them properly instead.
