The new flagship mountune m235 power upgrade for the Mk8 Fiesta ST releases the ultimate potential from the ST's 1.5-litre 3-cylinder EcoBoost engine, substantially yet safely raising power and torque output; improving performance and drivability, whilst adding a host of functionality, unique to mountune.
As with all mountune upgrades, it's had to pass 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 that you're not just buying the best upgrade for your Fiesta ST, but also the most robust aftermarket calibration, too.
Peak power is increased to 235PS, whilst torque is uplifted to 350Nm but, as can be seen from the power graphs, it's the substantial increase throughout the rev-range and the way the torque is delivered that transforms the driving experience.
Working together with industry leading software and hardware teams has enabled the very latest technology available to be incorporated, taking mTune - and making it a whole lot smarter!
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!
m235 SMARTflash includes three calibrations, with unique functionality:
|Increased power and torque (235ps / 350nm)|
|More aggressive launch control strategy|
|Enhanced audible exhaust output in Sport / Track modes|
|Optimised no-lift shift functionality|
In addition, the SMARTflash app, which is available for Apple and Android users, also allows for easy future calibration updates and includes a handy VIN and calibration ID reader as standard.
The m235 calibration has been fully optimised around the mountune induction kit, which itself delivers a 1.5kPa pressure drop, allowing the engine and turbocharger to work more efficiently in achieving the increase in power and torque.
Induction noise is also boosted and, with an engineered approach that retains the OE appearance, the airbox provides a subtle improvement to engine bay aesthetics, whilst also capable of flowing enough air to support further, future increases in power output.
m235 is available in two versions that support all known regional variations and as it can be installed and removed anywhere in the world, at any time yourself, you could say the power's in your hands, quite literally!

Easy to install and well worth doing. Brings the mk8 st performance out. Just do it
Nice and easy to use
Already had installed the high-flow throttle body. When added the m235 upgrade with the airbox the car became even funnier to drive and more responsive. If you want a power upgrade that just improves your car without great daily usability, this is for you! As an added bonus I am beginning to suspect that at slow speeds we are able to have a higher mpg.. But all this depends on how hard we use the loud pedal. :)
Please note: All hardware is supplied as standard with a 12-month, 12,000-mile warranty against manufacturing defects.
Installing the m235 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.
