Custom ECU tuning for your car

At our Llandow workshop, we custom tune supported Ford, Volkswagen (VW), SEAT, Skoda, Audi, BMW and MINI vehicles. The car stays with our tuning team while we check its setup, adjust the calibration and verify how it responds. The process depends on its ECU, hardware, condition and the work agreed.

We work with customers travelling from across the UK for custom tuning on supported vehicles. Tell us the model, engine, year and modifications and we will confirm whether the car is suitable before you book.

Know who is doing the calibration

A workshop can fit a file without developing it

Three common routes are often described with the same words. Ask who developed the software, what was checked on your car, and whether the calibration can be revised from its data.

Reputable off-the-shelf map

A calibration developed for a defined engine and software setup, then sold for use on compatible cars. A good OTS map can be a sensible option when the car matches its specification and the installer checks the vehicle.

It is designed for a group of vehicles, so it is not the same as developing the calibration around your individual car.

File-agent installation

A file agent reads the car’s ECU file, sends it to an external supplier, then installs the file that comes back. The supplier may provide a reputable, tested product; other files may have little visible development or test history.

"Agent" describes who supplies the calibration. It does not, by itself, tell you whether the file is good or bad. Ask what checks, logging and revisions are included.

Custom calibration at Llandow

Your car is at our workshop while we confirm its setup, assess its condition and calibrate it for its actual hardware and intended use. Where the vehicle and job are suitable, we use dyno measurements and live data to make adjustments and check the result.

Our tuning team carries out the work, with the vehicle available for measurement and revision.

Work from our workshop

See examples from real vehicles

These workshop stories show cars we have worked on and the results recorded for those jobs. They are examples, not a promise that another car with the same badge will make the same figures; engine condition, hardware and software all matter.

Custom tuning questions

Share your vehicle details and what you want to change. We can explain the options for your exact setup.

Enquire about custom tuning
What makes an ECU tune custom?

Custom tuning uses the individual vehicle’s specification and measured behaviour to develop and check calibration changes.

Are off-the-shelf maps always a bad choice?

No. A reputable OTS calibration can work well when the car matches the supported specification and the installer checks its condition. It is simply a different service from tuning the individual car at Llandow.

What should I ask a tuning centre?

Ask who develops the file, which checks and logs are included, whether revisions are available and how the result is verified.

Can I travel to Llandow from elsewhere in the UK?

Yes. Customers travel to our Llandow workshop for supported custom tuning. Send the make, model, year, engine and modifications first so we can check what is available and plan the visit.
