mTune SMARTflash m235 Upgrade [Puma ST]

The mountune m235 power upgrade for the all-new Puma ST provides a substantial uplift in the performance from the ST's 1.5-litre 3-cylinder EcoBoost engine, 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 'first stage' 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!

The latest version of SMARTflash also provides additional functionality, such as: fully configurable gauge displays using the OBD data-stream, comprehensive data-logging and a built-in performance meter, too.

m235 SMARTflash includes four calibrations, with unique functionality:

  • m235 performance calibration
Increased power and torque (up to 235PS / 350Nm)
More aggressive launch control strategy
Enhanced audible exhaust output in Sport / Track modes
Optimised no-lift shift functionality
  • m235 ASMO performance calibration
    Increased power and torque (up to 235PS / 350Nm)
    More aggressive launch control strategy
    Anti Social Mountune Overrun Enhanced audible exhaust output in Sport / Track modes (for those who really like their pops and bangs)
      • Stock performance
      • Anti-theft

    Please note: in order to update to our SMARTflash V2 release, you will now need to download our partner app, ECU Connect - once 'mountune' is selected within the tuner menu of the app you will have full access to the SMARTflash V2 features.

    For assistance setting up and installing SMARTflash V2, please refer to the user guide, here.




    Important: In order to achieve and maintain performance and reliability, the m235 upgrade should be used in conjunction with the hardware listed below. To achieve peak performance figures 97RON+ fuel should be used, however, it remains perfectly safe to use everyday and for all uses on 95RON fuel.

    Recommended m235 hardware:

    m235 supports 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!

    The phone device is shown for illustration of SMARTflash app only, and is not included with this product.

    PERFORMANCE REIMAGINED

    m235 delivers a substantial, yet safe increase in power and torque across the entire rev-range.

    Genuine gains of up to 30nm and 35ps over the oe calibration transform the driving dynamic and in-gear performance.

    power output may vary based on individual vehicle condition, fuel grade and method of recording.

    Please note: installing the m260 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.

      M235 Puma ST

      Product works fantastic, super easy to set up, install and even switch modes. The Anti-theft mode gives me that extra piece of mind at night, especially as keyless cars have been getting stolen more regularly from my area. As for the performance mode, WOW! You can certainly feel the difference. It makes the car much more responsive, all whilst maintaining the same reliability and even better fuel economy! I couldn’t reccomend this purchase enough.

      Best Investement ever

      My expectations were far behind than how the m235 kit really feels like. I owned a Fiesta ST before and the Puma ST was slightly less responsive in lower rev ranges. It also felt a bit slower. The mountune software solved this issue perfectly and made the Puma even feel faster than the Fiesta. Wow what a massive difference! Feels like a completely new car without changing the character of the beloved stock map that much. Even the drive modes kept their character. Just more punch through the whole rev range and look at that massive improved top speed! In ASMO mode the pops and bangs are just rediculous and make so much fun! It is just not describable with words how this slight upgrade feels to drive even without installing the recommended air box. Fuel consumption is even lower or the same than stock, which is great too. Installation was quickly and easy like a software update on your phone! Mountune states it takes them around 3 hours to provide you the software files. That was just not the case - it took just 10 minutes! That was insanely quick! Thanks! What makes me feel save about this upgrade is, that you can easily go back to stock map with one click and Mountune is a trusted ford partner for many years. You get a lot more performance without need to worry about durability. In some cases even warranty approved! Definitively worth the money!
