The mountune m235 builds upon the performance of the previous calibration, offering a further step up in power, torque and overall performance for owners of the Mk7 Fiesta ST. Developed to safely maximise the potential of the 1.6-litre EcoBoost engine, the m235 delivers enhanced acceleration and drivability, whilst retaining the refinement and usability expected from a mountune performance calibration.

As with all mountune upgrades, all of the performance calibrations have been through our own stringent durability testing criteria to ensure engine robustness, whilst retaining all safety parameters, so you can have complete peace of mind. This upgrade also reads the standard calibration found on the vehicle at the time of upgrading, allowing you to easily return to stock if needed.

The mTune SMARTflash app allows you to easily DIY install and update calibrations to your ECU using nothing more than our app, the supplied Bluetooth OBD interface and your Smartphone; no laptop, no wires, no handsets, no problem!

The latest version of the app also provides data-logging, a fault code reader and a performance meter - for additional peace of mind, there's also an anti-theft option than can be easily installed to immobilise your vehicle.

Existing owners of the Ford endorsed MP215 or MR230 upgrades can unlock the additional power, torque and functionality using the existing owner upgrade option. MR230 owners can also benefit from this higher performance calibration without the need to reset their cam timing to standard.
