mTune SMARTflash m330 to m365 Upgrade [Mk4 Focus ST] - electronic download

This option is for you if you're an existing m330 SMARTflash customer that wants to take advantage of the enhanced power and torque output of the m365 calibration.

The mountune m365 power upgrade for the manual and automatic Mk4 Focus ST takes power and torque to another level, delivering effortless performance, even more drivability and a soundtrack that really befits Ford's flagship ST model.

Utilising the required, carefully engineered hardware upgrades to reduce a substantial bottleneck in the exhaust system, the m365 calibration fully optimises this available headway and increases peak power to 365PS, with torque raised to a substantial 560Nm.

As with the previous m330 release, for optimum performance, engine efficiency and reliability,  the following hardware should be installed when migrating to m365:

Recommended in addition to the above:

The m365 SMARTflash upgrade includes the performance calibrations with the following features:

  • m365 performance calibration
Increased power and torque (up to 365PS / 560Nm)
More aggressive launch control strategy
Enhanced audible exhaust output in Sport / Track modes (manual only)
Optimised no-lift shift functionality

Important please read:
 In order to achieve and maintain the optimised performance and reliability, the m365 calibration should only be used in conjunction with the hardware listed and be used with 97RON+ fuel where possible. 

Please ensure you are using SMARTflash V2 accessed via our partner app, ECU Connect.  Once your new calibrations have been uploaded to your online account they are automatically added to your smart device when you next run the ECU Connect / SMARTflash V2 app.

You will already require an m330 SMARTflash upgrade / app, to be able to install this companion calibration.

Installing the m365 calibration without the correct hardware may result in failure to achieve the quoted power / torque figures, abnormal running, detrimental fuel consumption or engine warning light illumination or, in extreme circumstances, damage to and / or failure of the engine. in any such instance no warranty is offered or implied by mountune.

By purchasing this product you agree for mountune to send you emails about new updates or technical features relating to SMARTflash. You can opt out at any time.

    The last piece puzzle

    Finally got m365 onboard after all the exhaust system done. The sound of the very first fireup is astonishing, immediately makes the power upgrade impression. Then the driving experience also impressed me in terms of the noticeable more active response comparing to m330. It’s been a pleasant journey gradually upgrading from the original configuration and feel the change along way. Really appreciate the total solution from mountune
