How to send a file to our portal: what we need, credits and revisions

The File Service portal was built so you can send reads and receive finished files without email back-and-forth or waiting on the phone. The process is simple, but the details you give make the difference to speed and result.

Step 1: Registration and approval

1. Go to the registration page and fill in your business details.
2. In the tools field, write which tools you use, whether each is master or slave and, where relevant, the serial number. For slave tools this is essential, as we explain in our article on master and slave tools.
3. We review the application and activate the account. You'll get an email once it's ready.

Step 2: Credits

Each job is charged in credits, depending on the options you request. Credits are loaded onto your account by us after payment. The Credits page shows your balance and every movement: top-up, charge, refund. If you don't have enough for a job, the portal tells you before you submit.

Step 3: New job

These are the details we ask for, and why:

1. Vehicle: make, model, engine, year and VIN. The same ECU is fitted to different engines with different limits.
2. ECU, hardware number, software number: as your tool showed them. They let us confirm the file is what you say it is.
3. Tool and master/slave: these decide the format we return the file in.
4. Read method: OBD, bench or boot/BDM. It affects what the file contains and how it will be written.
5. Options: one main calibration option (Stage 1, Stage 2, Eco, gearbox, or options only with no power increase) plus any extras you need. Options that concern emissions systems are intended only for competition or off-road vehicles, where the law allows.
6. Notes: anything that doesn't fit elsewhere. Hardware modifications, fuel, gearbox type, the customer's goal, fault codes present beforehand.
7. The file: exactly as it came off the tool, unmodified, up to 32 MB. See also our guide to a clean read.

Credits are charged on submit. If you cancel before we start, they are refunded.

Step 4: Tracking

The job moves through "Submitted", "In progress" and "Completed". If we are missing information, the job moves to "Waiting for information" and we write to you in its messages. Your reply puts it back in progress. The more complete the details from the start, the less often that happens.

During business hours (Monday–Friday, 09:00–17:00 Greek time) turnaround is usually under 60 minutes. Files that arrive outside those hours are handled on the next working day.

Step 5: Download and the WTC sheet

You get an email when the file is ready. From the job page you download the file and the WTC (What To Check) sheet. The WTC lists which maps were changed, which monitors were disabled, what must be in place on the vehicle before flashing and what to do afterwards: clearing codes, adaptations. Read it before you write.

Step 6: Revisions

If something isn't right, request a revision from the job page. Be specific:

• what you see and in which conditions (rpm, gear, temperature),
• which fault codes appeared,
• if you have a log, what it shows.

A description like "cuts out at 3,000 rpm in third, boost pressure fault" takes us straight to the fix. "It doesn't run right" doesn't help.

Why it's worth it

Every file is developed at our workshop in Athens, by the team that has been proving calibrations on its own 4WD dyno since 2003.
