A little clarity goes a long way.

Create an account, verify your email and complete your billing profile. Purchase credits, upload your original ECU or TCU read with vehicle details and select your services. Your engineer reviews the request and returns the modified file through your account.

Make, model, year, engine, ECU or TCU identification, reading tool and connection method. Add hardware changes, fuel requirements, fault codes and clear expectations. A vehicle name alone does not confirm compatibility.

The price of every service is shown before submission. Credits are deducted when your request is successfully created. Confirmed Stripe credit purchases generate an invoice available in your Invoices page. Applicable taxes are shown at checkout.

Usually within 30min - 1h during Monday–Friday · 09:00–18:00 CET. This is an estimate; complex requests can take longer. Your request page shows its current status.

Open the completed request and select Request revision. Explain the issue and add logs or diagnostic details in the conversation. The revision stays attached to the same vehicle, original file and delivery history.

Files are stored outside the public static directory. Downloads require authentication and ownership or staff authorisation. Every download is recorded in the audit trail.

Verify that the file matches the exact vehicle, ECU, software and tool protocol. Follow your programming tool’s checksum and writing instructions. Calibrations are prepared manually; uploading does not automatically modify or validate your original file.
