About the workshop

Inside TuningFiles AT

A specialist ECU remapping and tuning file workshop built on inspection first, archived original files and calibrations that are measured, reversible and documented.

Specialist ECU remapping, tuning files and custom calibration.

TuningFiles AT exists because too many remaps are sold as magic and delivered as mystery. This workshop runs the other way round: the vehicle is inspected first, the original file is read and archived, and the customer is told exactly which calibration route fits — performance, economy, dyno-developed or diagnostics-led.

Cars, light commercials, HGVs and agricultural machinery all go through the same disciplined file workflow. Tuning files are prepared per vehicle, compared against the stock calibration and written with a guaranteed way back to standard. Dyno time is used where it earns its keep: custom work, modified engines and any job where the numbers need proving rather than promising.

The promises stay narrow and the process stays open. If a vehicle should not be tuned — because of its condition, its history or its warranty position — you will be told before money changes hands.

Specialist tuning needs equipment, software and a process that holds.

Vehicle first

Vehicle details, current faults and the goal of the tune come before any route is chosen. If tuning is the wrong answer for this vehicle, that gets said out loud.

File control

Original files are read, archived and version-controlled on every job. Each vehicle keeps a guaranteed way back to standard.
