mTune SMARTflash m330 Upgrade


The new mountune m330 power upgrade for the Mk4 Focus ST releases the maximum achievable power and torque from the potent 2.3-litre EcoBoost engine without significant hardware changes, substantially yet safely raising power and torque output; improving outright performance, drivability and fun, whilst also 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 tens of thousands of miles and many months accumulating extensive data such as in-cylinder pressure and other key metrics all based on different driving scenarios from road to track and when used on different fuel octane ratings 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 Focus ST, but also the most robust aftermarket calibration, too.

Peak power is increased to 330PS, whilst torque is uplifted to 515Nm 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 completely 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!

m330 SMARTflash includes three calibrations, with unique functionality:

  • m330 performance 
Increased power and torque (330ps / 515nm)
More aggressive launch control strategy
Enhanced audible exhaust output in Sport / Track modes
Custom Track Mode (recalibrated wet-mode for track settings minus 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 fault code reader, plus a handy VIN and calibration ID reader as standard.

The m330 calibration has been fully optimised to utilise the mountune high-flow panel filter, which allows the engine and turbocharger to work more efficiently, as well as improving induction noise.

m330 is available in two versions that support all known regional variations (excluding automatic transmission - support coming soon) 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 m330 upgrade
    (supplied with high-flow panel filter)
  • mTune SMARTflash m330 lite
    for owners that have already upgraded their panel filter)

    Another Winning Product From Mountune

    I upgraded my previous vehicle (Focus RS mk3) with the Mountune m375 kit, although this work was carried out by the garage that supplied the upgrade. I ordered the mTune SMARTflash m330 kit for my new ST and was looking forward to applying the upgrade to the vehicle myself and found it easy to install after following the clear instructions supplied.  After downloading the easy to use app for my iPhone, I then sent the embedded email message to Mountune which was picked up within office hours and I quickly received a reply with the upgrade files attached. The required files were then transferred to the app and ready to use. The re-map is easily actioned and gives you a noticeable performance boost, delivering the power smoothly throughout the rev range. This now makes the ST a real pleasure to drive.  Well done Mountune for delivering yet another winning product!

    Focus ST M330

    This is the first time I have ever used Mountune, they quickly replied to my emails, and the files were quickly sent too, the whole process with easy to follow steps with pictures was a breeze, you can't go wrong, anyway once the files were uploaded it totally transforms the car, I thought in standard form the car cane alive in sport mode, but this is just epic, so much more responsive and the car just wants to get up and go, should have came out like this, I absolutely love it, its just perfect now, I always warm the car up first before a quick blast and cool it down before I turn the car off, the other reason I got this was for the anti theft function, that's a no brainer in my eye, totally disables the obd port, if you're thinking of buying this, don't hesitate, GET IT BOUGHT, what a car, brilliant

    A must have

    A must have for the Focus St!! For the money no better upgrade. My only issue was knowing if I was running the car with flash activated, but once I drove the car you noticed the difference instantly. All we need now is the air filter and the induction and maybe another flash for more horses
