Frequently asked questions

Before you open a portal job.

Add the brand, exact model, year, engine, VIN/PIN or machine serial, ECU part and software numbers, current faults, read tool, country of use and requested service. Complete identification helps engineering confirm the correct path.
Yes. Submitting the original file does not spend tokens. Engineering reviews the job and assigns the exact token quote. Tokens are charged once only when you unlock the completed result.
Each uploaded binary is stored as an authenticated XChaCha20-Poly1305 encrypted blob with random naming and SHA-256 fingerprints. The file is delivered only through an authorized signed-in download.
Yes. Each job has its own customer–technician message thread, status history and file record, so the technical conversation remains attached to the correct equipment and ECU.
The portal uses a token wallet and records every credit and debit. Stripe card checkout and PayPal can be offered when those payment integrations are enabled by the administrator.
No universal support is promised. Compatibility depends on the controller, software, available tools, file quality and requested work. Regulated-system services are considered only for authorized use where the work is lawful.
