A sharper response makes a familiar road more enjoyable, from the first squeeze of the accelerator to the pull through the gears. Our ECU remap for your 2022-2025 Ford Focus 2.3L EcoBoost MK4.5 focuses on throttle response and usable mid-range performance.
We use your car data to refine throttle response and mid-range delivery for the fuel you use and any fitted intake or exhaust parts. Vehicle condition matters too. The manual configuration has a 420 Nm factory torque reference: that is its original output, not a tuning gain.
Our custom tunes include up to four revisions in the first 30 days, followed by log reviews at 3, 6 and 12 months. Your feedback helps us refine the calibration and check how your vehicle is running after you have had time to use it.
We also offer physical upgrades for most vehicles.
If an intake upgrade is part of your plans, our MST intake and inlet-pipe kit brings the pipework, reusable dry filter, heat shield and fitting parts together for the Mk4 ST 2.3 EcoBoost. We can develop the calibration around the intake fitted to your own car.
The intake is an optional separate purchase; you can also choose this tuning service with your standard hardware.
If you're looking to take yours further, tell us what you have in mind. We can help you choose suitable parts and plan the tuning around them.
| Option | What you get |
|---|---|
| Custom Dyno Calibration | In-person custom calibration on the car hub dyno, with controlled-load testing and vehicle data guiding the work. |

With remote tuning, we can work with you without a trip to the dyno. First, we confirm support for your vehicle and check its fitted hardware and the fuel you plan to use. We then guide you through reading and loading the calibration with the device. Send us the requested logs and your feedback so we can check the response and refine the tune.
Custom Remote Tune includes the tuning device, required licence and delivery. You keep the device.
Collect any requested data in a suitable, safe and lawful setting, following the tuner instructions. If a reading or a running concern needs attention, tell us before continuing so it can be assessed.
Choose Custom Dyno Calibration for an in-person session on the hub dyno. We use controlled-load measurements and live data to check the response as we adjust the calibration, with your own vehicle and fitted parts present throughout.

No fixed gain is guaranteed. The 420 Nm reference describes factory torque for the manual configuration, rather than a promised tuned result. Your fuel, hardware, condition, temperatures, logs and the tuning route affect the outcome.
Yes. We can calibrate the car in its current specification. If you later change parts that affect airflow or fuelling, the tune may need another review.
Tell us before fitting parts that affect engine operation or fuelling. The calibration was developed for the current combination, so further tuning may be needed.
Up to four revisions within 30 days, followed by log reviews at 3, 6 and 12 months to check how everything is running.
