mTune SMARTflash m330 Upgrade

47 reviews


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)

Please note; the m330 in currently unavailable for Australian specification cars due to different emission standards on Australian vehicles

    Focus ST M330 Smartflash

    Received M330 Smartflash Lite one working day after ordering, had previously purchased high flow air filter. After following the installation guide and emailing my vehicle details to Mountune I had a reply within 3 hours containing the M330 upgrade files. Took about 15 - 20 minutes to complete the rest of the upgrade with no issues apart from the error with Hill Start Assist which Mountune had already explained would clear as soon as I drove the car. In regards to the actual car performace it adds that extra edge that it was missing, just wants go and go, on the motorway is when you realise how quick this car is now, the difference from stock is massively noticeable. Highly recommend this upgrade as long as your prepared to accept it will affect your standard Ford warrantee which I personally thought was an acceptable risk considering my past experience with Mountune upgrades has been problem free and positive.
