mTune SMARTflash m235 Upgrade

  

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:

  • m235 performance
Increased power and torque (235ps / 350nm)
More aggressive launch control strategy
Enhanced audible exhaust output in Sport / Track modes
Optimised no-lift shift functionality
  • Stock performance
  • Anti-theft

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!

  • mTune SMARTflash m235 upgrade
    (supplied with induction kit)
  • mTune SMARTflash m235 lite
    (
    for owners that have already upgraded their induction kit)

    WOW!

    Straightforward and easy to fit even for a novice "mechanic". Instruction guide clear and concise (just make sure you have the correct set of tools needed for the installation). What a difference! Turns the ST into a proper Pocket Rocket - just wow! Well worth the money - thank you Mountune.

    Just get one

    It just works. The package is the standard ST for driving but with more of everything. It feels factory fitted. It's easy to fit, about 30mins or so. And once the software is loaded, you just drive. Torque is vastly improved and this has benefits for the bland motorway journeys as the car seems less frantic and smoother to drive. And the extra power and torque makes back roads a blast. It's a great package, it works and doesn't feel aftermarket. I'm very impressed.

    M235

    Previously I owned a 2013 Mk7 FST from new, after 6 months I upgraded to MP215 . Thats was impressive on the motorway. The Standard Mk8 seemed quicker acceleration low down, but slower than the Mk7 MP215 on motorway, especially changing speed to overtake. Hence I went for this MP235 after 1 year of ownership. First reaction was too much power, due to installing it when the weather was wet (I've good original tyres, and the LSD). However, now the weather has dried up, it seems imminence power and acceleration, likely more than I'll ever want in this car. It does unfortunately point me to wanting more grip in poorer weather conditions, so contemplating the PE. coil overs next. If you own a PE ST, I'd say don't even hesitate - it's fantastic. If you've worn tyres, get them changed first, then buy it, you wont be disappointed. It was easy to install, and very fast service from mountune.
