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)

    Perfect

    First, I received the upgrade very quickly and well packed. The installation is quite easy, but I would have prefer a guide or a link to the guide on the internet (https://m.box.com/shared_item/https%3A%2F%2Fmountune.app.box.com%2Fs%2Fxsnh8m76c61ikvobvkivekek1v4tsq13/browse/18617295593). Espacially for the porous air hose. The m235 upgrade is really easy to install with the app and thanks to mountune reactivity. It works perfectly, the car is more powerfull and equally more pleasant to use even when I drive smoothly. The exhaust improvement sound very well without being too loud. Thx Mountune

    Great product and value for money

    Easy and straightforward from buying of product to installation, really does make a difference especially mid range and top end. Can be cruising at 60 in 6th gear on the motorway, put your foot down and its impressive how quickly the car gains speed compared to stock meaning you needn't change gear at all.
