What’s better than more power? Even more
power, obviously, and Mountune is well aware of that. Last year, the UK tuner
released the m225 power kit for the Ford Fiesta ST, boosting the stock
1.5-liter turbocharged three-pot to 225 PS and 340 Nm of
torque. Now, Mountune has developed an m235 upgrade which, you’ve guessed it,
bumps power to 235 PS.
While at it, the aftermarket specialist
also increased peak torque by a further 10 Nm (7 lb-ft) over the m225 kit to
350 Nm. As you can imagine, the added power and torque have a
positive impact on the Fiesta ST’s performance, though Mountune does not detail
the gains in acceleration and top speed.
The company does say that the
m235 package maximizes the potential of the 1.5-liter three-cylinder EcoBoost
engine by spreading the power and torque gains over the majority of the
rev-range. Included within the calibration is the no-lift shift optimization
which is said to make smooth and precise lift-less gear changes easy. Combined
with the enhanced exhaust overrun, this will create “an optimum driving
experience.”
As with the m225 kit, customers can
install Mountune’s new m235 upgrade from the comfort of their driveway using
the mTune SMARTflash app. All they have to do is install the app on their
smartphone and plug-in the supplied Bluetooth OBD interface.
The SMARTflash app also allows users to
select between different calibrations as well as update their vehicle with the
latest calibrations directly from Mountune. There are three distinct
calibrations included with this specific upgrade. The first one is called m235
Performance and it adds a more aggressive launch control strategy and enhanced
audible exhaust output in Sport/Track modes; Stock Performance is the second
and it reverts the vehicle to standard configuration); finally, Anti-Theft
fully immobilizes the car.
The mTune SMARTflash m235 package is
priced at £ 575 (US$ 750) when upgrading from stock.
