Behind the scenes

What happens to your file.

Every automatic file runs through the same checks, in seconds. If anything doesn’t match, like an unknown software version or a modified original, it’s stopped and passed to an engineer instead of being guessed.

  • ECU hardware and software version verified
  • Only the options you chose are applied
  • Unknown files go to a person, never guessed

How fast is an automatic file?
For supported ECUs and standard options, the file is usually ready within minutes of uploading, at any time of day.

              
What if my ECU or request isn’t automatic?
It goes to an engineer, who handles it during support hours. You can follow its status in your account and you’re notified when it’s ready.

              
What if the file needs a change?
Open the file in your account and send a revision request with your notes and logs. We’ll update it.

              
Do I get an invoice?
Yes. Every credit purchase creates an invoice automatically in your account.
