Our m400 Focus RS upgrade has now been superseded by an enhanced version, called the m400R. Think of it as m400. But reimagined.
What's new we hear you cry?!... well, you still get our m400 calibration, but this is now joined by a standard power output and fuel economy calibration, too.
This option is for customers who already have the hardware required for the mountune m400R upgrade kit installed on their Focus RS and that require the supporting calibration and / or that want to benefit from the additional functionality of the mTune handset and is supplied with two mountune badges (only with new handset orders).
Utilising a selection of fully proven mountune hardware - some of which endorsed by Ford themselves, to help lower charge temperatures, improve pressure drops and remove back-pressure, means the engine is now able to operate more efficiency, allowing the impressive peak 400PS and 560Nm power and torque output to be more safely, and reliably achieved.
Please Note: The warranty of the vehicle being updated with this upgrade may be affected. The m400R upgrade kit is not Ford-endorsed.
To maintain any warranty provision otherwise entitled to you, and to ensure correct operation and reliability, calibrations loaded via an mTune handset must be installed together with the correct mountune® hardware.
Support is not currently available for vehicles in Asia-Pacific, this will be added in the next firmware update.
m400 > m400R firmware update is currently offered FOC to existing customers - please ensure you include your serial number and FMP number in the notes section when checking out.
NOT COMPATIBLE with vehicles in North America. Please visit our US website for compatible Focus RS products - www.mountuneusa.com
