Calibrators, not a file library
AI Tuningfiles brings four established tuning businesses together under one roof. The people behind your remap files have spent more than twenty years on rolling roads, in race paddocks and in the workshop.
We use AI-assisted tools to find maps and compare software versions quickly – but every tuning file is checked by a human calibrator before it is released to you.
That means each file is written for the specific vehicle, engine, ECU and hardware in front of you. If something looks wrong in the read, we tell you before you flash.

Remapping in the UK – what your customers should know
Insurance
A remap counts as a modification. Advise customers to tell their insurer before driving on the road.
MOT & emissions
Removing or disabling a DPF, EGR or AdBlue system on a road vehicle can cause an MOT failure and is not legal on UK roads. Those solutions are supplied for off-road, export and motorsport use only.
Warranty
A remap can affect a manufacturer or dealer warranty. Our back-to-stock option lets you return to the original software at any time.
Tuning file service – questions & answers
What exactly is a tuning file?
A tuning file (also called a remap file) is a modified version of your ECU's original software. We adjust maps such as boost, fuelling, timing and torque limits to release more power and torque, and return the file ready to write back to the car.
How quickly will I receive my tuning file?
Most car and van files are completed within 5–15 minutes of upload during opening hours. Rare ECUs, bikes, trucks and agricultural machines can take a little longer.
Which reading tools do you support?
We accept reads from all the common tools – Alientech KESS3 and KTAG, Autotuner, Magicmotorsport Flex, CMD, bFlash and others – whether read via OBD, on the bench or in boot mode.
Do you write files for vans, 4x4s and pick-ups?
Yes. Transit, Transit Custom, Sprinter, Transporter, Ranger, Hilux, L200 and Defender are among the vehicles we see most often from UK customers.
Can I become a tuning file reseller?
Yes. We set up a white-label portal under your own brand and domain. Your customers upload to you, we do the calibration work in the background and you set the prices.
