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 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 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 Puma ST, but also the most thoroughly tested, 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 an really brings your Puma to life!

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 the following 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

    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.





    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!

      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.

      By purchasing this product you agree for mountune to send you email about new updates or technical features relating to SMARTflash. you can opt out at any time.

        How it should have been

        Amazing. For me, coming from a MK8 ST with the M260 package the Puma was stock pretty underwhelming power-wise. The M235 package is what you MUST have on your Puma to make the actual fun package. It’s so close to my M260 Fiesta times, I never imagined it to be that close.

        Perfection

        It's a fantastic upgrade and has brought the Puma to life. The throttle response isn't as sharp or jolty like with the stock map and is smoother giving instant power throughout the entire rev range. In ASMO performance calibration mode the exhaust overrun coupled with the pops and bangs are ridiculous and puts a smile on my face! It got delivered the next day and came with branded packaging, very clear instructions and delivered the ROM files instantly along with a nice surprise of a Mountune badge. Mountunes 30+ year heritage specialising toward Ford ST's and RS's offsets any concerns about warranty invalidation. The extra price that you will pay for Mountunes remap is worth it over other suppliers, due to that they specialise with Fords, only focussing on a small subset of engines tuning in the safe confines for reliability and sustained performance. For the UK Customers, Ford finance have had no issue in authorising the upgrade, they were super responsive using their online portal. It added nothing onto my insurance premiums. Thanks Mountune!

        We're glad you like the upgrade and thanks for sharing the shot of your Puma ST! Obviously we can't control the laws on taxes, but the price you've paid will be almost identical (usually only 1-2% different) to what you would've paid pre-Brexit, you're just paying taxes into your own country at their rate rather than the 20% of VAT to the UK that all customers were previously paying before January 1st.
