A file service lets your workshop offer ECU remapping without doing the tuning yourself: you read the customer's ECU, upload the file, and receive a custom-tuned file to flash back. MasterTuning produces the file, you keep the customer and the margin — with technical support at every step.
How it works, step by step
- Read the ECU with your tool (OBD or bench).
- Upload the original file to the MasterTuning portal, choosing the tuning (Stage 1/2, DPF, EGR, etc.).
- Receive the custom modified file, usually within minutes to a few hours.
- Flash it back and deliver the car to your customer.
