mTune SMARTflash m225 to m235 Upgrade

this option is for you if you're an existing m225 SMARTflash customer that wants to take advantage of the latest power and torque increases, the newly added optimised no-lift shift function and and our further enhanced exhaust overrun.

As with the previous m225 release, for optimum performance and engine efficiency, we recommend the use of our high-flow induction kit in conjunction with the performance software changes.

Increased power and torque (235ps / 350nm)
More aggressive launch control strategy
Enhanced audible exhaust output in Sport / Track modes
Optimised no-lift shift functionality

please specify your vehicle vin in the notes section when checking out. and if the email used to make this purchase is different to the one used for your original m225 purchase, please also supply that to ensure the industrialised calibration to support your vehicle is created and sent to you correctly.

the file emailed to you can then be opened via the SMARTflash app and installed to your ecu, as is the case with all previous calibration updates using your OBD bluetooth adaptor.

please note: you will require an m225 SMARTflash upgrade / app to be able to install this companion calibration.

    A noticeable improvement in performance. The car feels more responsive to throttle increases, and the acceleration improvement continues up to the red line. Seems like more of an increase than 10 bhp and 10 Nm of torque.
