About TunedFile
A file service for tuners and workshops, built on ECUFAST engineering experience going back to 2012.
TunedFile is the file service of ECUFAST USA. We write ECU and TCU calibrations for workshops, resellers and enthusiasts who read and write the vehicle themselves and need a reliable file back fast.
How we work
- Every request is handled by hand. No file goes out from a template.
- Each file is checked against the platform's limits — torque model, knock strategy, thermal protection and shift logic — before delivery.
- Requests, files and revisions live in one panel, so nothing gets lost in chat history.
Who we work with
Independent tuners, performance workshops and resellers across North America, Europe and beyond — cars, vans, trucks, agricultural and motorcycles.
