For mod lovers and Fiesta ST owners, you’ll appreciate the upgrade package for the Mk8 Fiesta ST by mountune. Mountune has unveiled several performance kits for the mass market. The kits do not alter the OEM+ feel too much, according to the tuners.
The Fiesta ST’s kit is the m235 package which pushes up power and torque, by 10 PS and 10 Nm. The m235 upgrade has undergone a rigorous testing and development process to once again deliver a package that puts the driver firmly in control. An extended durability cycle monitoring cylinder pressures with the use of additional ignition, now provides a significant and useable increase across the majority of the rev-range versus the previous m225 kit, maximizing the potential of the 1.5- liter 3-cylinder EcoBoost engine.
There are three calibrations in this upgrade: Performance, Stock and Anti-theft. Performance mode offers a more aggressive launch control and enhanced audible exhaust output in Sport/Track modes. The other two calibrations Stock, which returns the vehicle to its standard configuration and Anti-Theft, which fully immobilizes the ST.
With this upgrade, the Fiesta ST now boasts a peak power output of 235 PS and 350Nm of torque. Apart from increased output, there’s lift-less gear changes and an enhanced exhaust. Then, there’s the SMARTflash app, by using the app on smartphone and the supplied Bluetooth OBD interface, Fiesta ST owners can completely change their vehicle settings. The intuitive SMARTflash system has been designed to make selection between different calibrations simple and fast. And updates are delivered by mTune as well.
