Take your mountune equipped Mk3 Focus RS to the next level of performance with this upgrade from standard or the m380/m375 calibration to either the  m400R or m400X. This ultra-convenient, smartphone-based upgrade delivers significant gains in power, torque, and drivability while retaining all the safety and durability assurances mountune is known for.

As with all mountune upgrades, all of the performance calibrations have been through our own stringent durability testing criteria, which included additional months of in-cylinder pressure monitoring to ensure engine robustness, whilst retaining all safety parameters, so you can have complete peace of mind. This upgrade is also supplied complete with a standard calibration too.

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!

Once you've selected one of the three performance calibrations and installed it from the SMARTflash app, you'll be able to switch between the regular version and the + version of that calibration by pressing and holding the 'cancel' button on the steering wheel.

The latest version of SMARTflash also provides additional functionality, such as: adjustable launch control, fully configurable gauge displays using the OBD data-stream, comprehensive data-logging and a built-in performance meter, too.

Please see the table below for the full list of functionality that comes as standard with this upgrade option.
