What is an ECU file service?
An ECU file service is a structured workflow where the customer provides the vehicle context, selected service and original controller file through a secure request process. MG AutoTech keeps the request status and delivery inside the customer portal.
What is a TCU file service?
A TCU file service focuses on transmission-controller requests. The request should include gearbox or controller context, vehicle information, selected service and clear technical notes for review.
What is the difference between Stage 1, Stage 2 and Stage 3?
Stage 1 is generally reviewed for standard or near-standard hardware. Stage 2 is tied to documented supporting modifications. Stage 3 is an advanced custom project requiring a complete build specification, technical review and a credible logging or revision path.
Are ECU tuning files vehicle-specific?
Yes. The request is reviewed against the submitted vehicle, engine, ECU software, original-file context, fuel, gearbox and hardware setup. A stage name alone is not enough.
Can I submit a file read by AutoTuner, KESS, Flex or another tool?
State the tool and the OBD, bench, boot or virtual-read method when submitting. Tool name alone does not prove file coverage or originality, so the controller identity and source context are still reviewed.
What information is needed for a tuning file?
Provide vehicle and engine data, transmission, ECU HW/SW where available, original file, read method, fuel, installed hardware, requested services and relevant fault or log context.
How do I receive and download the tuned ECU file?
Delivered versions appear inside the authenticated order page. The customer can track status, read customer-visible messages and download the completed file from the private portal.
Can a file be revised after testing or data logging?
Where a revision is appropriate, the request and supporting observations or logs remain attached to the same order so the delivered-version history stays traceable.
What happens if the uploaded file is not original?
Do not hide uncertain file history. Mention previous work and use the ECU file-check route when originality, identity or read coverage needs verification before another service is considered.
Do you support petrol and diesel engines?
Supported petrol and diesel applications can be reviewed, but controller families, operating strategies and evidence requirements differ. Exact support is confirmed from the submitted identity and file context.
Do you offer TCU tuning files?
Selected TCU and gearbox-controller requests are supported. Submit a separate original TCU file, exact controller identity and engine torque context where ECU and TCU behavior must be coordinated.
Can workshops and professional tuners use the service?
Yes. The workflow is designed to keep repeat file requests, technical notes, status, customer-visible communication, delivered versions and revisions connected to the correct account and order.
Is this an ECU file-management software product?
MG AutoTech provides a secure customer portal for file submission, order status, request history, messages, revisions and downloads. It is a service workflow, not a standalone ECU editing application.
Does this public page upload, inspect or modify files?
No. The public page explains the service. File submission and private technical handling begin only inside the authenticated customer request flow.
