mTune SMARTflash m225 Upgrade


The mountune m225 power upgrade releases the potential from your Mk8 Fiesta ST, substantially yet safely raising power and torque output from the ST's 1.5-litre 3-cylinder EcoBoost engine; 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 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 225PS, whilst torque is uplifted to 340Nm 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!

m225 SMARTflash includes three calibrations, with unique functionality:

  • m225 performance
Increased power and torque
More aggressive launch control strategy
Enhanced audible exhaust output in Sport / Track modes
  • 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 m225 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.

m225 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 m225 upgrade
    (supplied with induction kit)
  • mTune SMARTflash m225 lite
    for owners that have already upgraded their induction kit)

    Remap by yourself... fun to do it like this

    Well followed and fast delivery. No major problem, I just had to wait the next day to receive the remap-stock-immobilizer files by email. So not within 2 hours as indicated ... The application has changed a little bit, so not completely like the pictures in the booklet. The remap takes a good 5 minutes, while your whole dashboard flashes, but a few dong later ... file transmit and remap finished. Off the ignition -> on the ignition and Start the engine ... and ENJOY. More great power ! And more pops and bangs, but not to too much. Just fine... What I like most is that the throttle is also modified, now when your are at 25% of throttle, your are at 25% of power ! And not at 50% like before. It's now more real....
