mTune SMARTflash m225 Upgrade


The mountune m225 power upgrade releases the true 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 also been thoroughly durability tested, with all safety parameters retained, 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, 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)

Great update!

Sinds enkele dagen heb ik de inductie kit geinstalleerd en heb ik zo de M225 upgrade op de wagen geprogrammeerd. Het resultaat is geweldig! Het is geen gigantisch groot verschil maar dat hoeft voor mij ook niet! Sommige andere tuners bieden meer paardenkracht aan maar deze 25 extra pk zijn voor mij een goede start. Maar voor mij is niet alleen het product belangrijk, ook de service en laat die net bij Mountune ook heel goed zijn! Ik woon in België maar ik heb al mijn producten steeds correct en tijdig aangekregen! Het voordeel van de Smartflash app is ook dat ik niet naar een garage hoef te gaan maar mijn product gewoon via de gsm kan updaten! Bedankt Mountune!

Just brilliant

I’ve installed the map via the Bluetooth device which was very straight forward. The gains in performance are really good the noise in sports mode is really nice. I’m just waiting to book my car into Mountune HQ to have the air box, High Flow Induction Hose and other bits and pieces fitted. This is a no brainier for the MK8 ST.

Mountune have smashed it again

I ordered the full M225 upgrade along with the primary intake hose and clips and since living local I picked the kit up within 4 hours of the HQ opening after the weekend which I thought was fantastic customer service. I installed the kit myself and was very straight forward, I had installed all the hardware (Mountune air box, K&N panel filter and induction hose) within 20 minutes and then loading the new M225 software onto my car only took about half an hour which was very straight forward. After install the weather was on my side and I cannot describe in words how much of a great difference it has made to the car, through the Rev range it doesn’t stop pulling. It pushes you back in your seat so much and from an already great stock car I didn’t think it was possible to make gains as much as the M225 has added. Yes there is other software that claims higher figures but for actual driving experience nothing beats the M225. Having the app on your phone also makes it so easy to change between the M225 and the stock map, having the anti theft system as well is great when leaving the unattended. I can’t wait to see what’s next in store for the MK8 ST from Mountune!
