Prices shown are starting prices. Final cost depends on your vehicle's make, model, and condition. We always provide a free estimate before starting work.
This is a **trade-only service** for garages, mobile tuners, and auto-electrical technicians. If you're a retail customer looking to have your own vehicle remapped, please see our standard ECU remapping services instead.
We provide professional tuning files and module-level repairs for workshops across the UK. Send us an original file read with your tool of choice — KESS/KTAG, Autotuner, CMD Flash, FLEX, Alientech, or similar — and we'll return a tested, checksum-corrected file ready to write back. For faulty modules we also offer a postal repair service: send us the unit and we'll diagnose, repair, and return it fully tested.
Our workshop has been supporting trade customers for years. We understand the pressure you're under when a customer is waiting on their car, which is why same-day turnaround is standard for file services and 24–48 hours for most postal module repairs.
Supported modules, tool list, postal repair workflow, legal notes, and trade account enquiries.
