! HOT DEAL ! mTune SMARTflash m225 Upgrade


Free UK delivery until 17th June!

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 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)

smartflash m225 Upgrade

Overall great purchase.Easily fitted and produces great improvement to an allready great car.Just wish you had pushed the rev limiter just a little to enable 100kph to be achieved in 2nd gear.This would reduce the 0 to 100 kph time significantly more.....

High-flow induction kit

our numbers don't lie.

m225 delivers a substantial, yet safe increase in power and torque across the entire rev-range. 
Genuine gains of up to 55Nm and 26PS over the OE calibration transform the driving dynamic and in-gear performance and also allows the sprint from 0-60mph to arrive in just 5.95secs and knock over a second off Ford's standardised in-gear 31-62mph benchmark!

Power output may vary based on individual vehicle condition, fuel grade and method of recording.

Please note: All hardware is supplied as standard with a 12-month, 12,000-mile warranty against manufacturing defects.
Installing the m225 calibration without the correct hardware may result in failure to achieve the quoted power / torque figures, abnormal running, detrimental fuel consumption or engine warning light illumination or, in extreme circumstances, damage to and / or failure of the engine. In any such instance no warranty is offered or implied by mountune.

By purchasing this product you agree for mountune to send you email about new updates or technical features relating to SMARTflash. You can opt out at any time.
