BLAG’s file service is built for professional users who can identify controllers, protect the original read, write software correctly, diagnose faults and validate the completed vehicle or machine.
One job, one technical thread
The portal keeps the original file, ECU identification, requested scope, messages and delivery together. This reduces the risk of mixing vehicles, losing diagnostic context or writing a file developed for a different software version.
- Create the professional account and open one job per vehicle or machine.
- Upload the untouched original and complete ECU, HW/SW and read-method data.
- Describe hardware, fuel, transmission, symptoms, DTCs and the required outcome.
- Answer technical questions inside the same job.
- Download the completed file, read the notes and follow professional writing procedures.
- Validate with diagnostics, logs and controlled testing appropriate to the application.
What a useful request contains
Vehicle or machine, engine, ECU, HW/SW and reading tool.
An untouched original plus current DTC and hardware status.
A specific operational result, not a vague percentage request.
Logs, codes, conditions and repeatable symptoms when support is required.
What the file service does not replace
A remote file does not replace workshop responsibility, correct battery support, professional writing procedures, mechanical diagnosis, emissions compliance or validation. The customer remains responsible for the condition, legal use and safe operation of the vehicle or machine.
Review the complete workflow, support and revision boundaries, and quality and validation before ordering.
Detailed ECU file-service scopes
Use the service library to check the exact inputs, diagnostic limits and validation required for the job you intend to submit.

Frequently asked questions
Who is the file service for?
It is intended for workshops, tuners, dealers and other professional users able to read, write, diagnose and validate ECU software safely.
Can I submit an already modified file?
State its origin and modifications clearly. An unknown modified file is not an untouched recovery reference and may need a verified original first.
How do I request support after delivery?
Keep the request in the same portal job and include exact DTCs, logs, file names, tool information and repeatable operating conditions.
