mTune SMARTflash m400R / m400X [Mk3 Focus RS]

Take your mountune-equipped Mk3 Focus RS to the next level with an upgrade from the standard calibration or m380+ to either the m400R or m400X.

This ultra-convenient, smartphone-based upgrade delivers significant gains in power, torque and drivability, while retaining the safety, reliability and durability standards that mountune is known for.

As with all mountune performance calibrations, m400R and m400X have undergone our stringent durability testing programme. This included additional months of in-cylinder pressure monitoring to validate engine robustness while retaining all key safety parameters.

Important: The m400X calibration is exclusively available for vehicles equipped with a forged engine. It must not be installed on an engine with standard internals, as the increased performance demands of m400X may result in engine failure. Customers with standard engine internals will therefore only be supplied with the m400R calibration.

The upgrade also includes a standard calibration, allowing you to return your vehicle to its standard configuration whenever required.

SMARTflash

The mTune SMARTflash app makes installing and updating your calibration simple. Connect the supplied Bluetooth OBD interface to your vehicle and use your smartphone to flash the ECU.

No laptop. No cables. No handset.

Once you've selected and installed your chosen performance calibration through the SMARTflash app, you can switch between the regular and + versions of the calibration by pressing and holding the Cancel button on the steering wheel.
