Due to overwhelming customer demand, the mountune engineering team have made available a calibration update for m225 SMARTflash customers that wish to have more 'pops and burbles' on exhaust overrun and when free-revving - even over those found in the m225 calibration as standard!
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.
Please note: You will require an m225 SMARTflash upgrade / app to be able to install this companion calibration.
nice and easy to use. just what the car needs
The new overrun calibration is insane, It makes a perfect amount of noise popping the whole time but not quite loud enough to be a nuisance if your doing longer journeys or dont always drive quick.. Message 07387236860 if u want recording. Definitly worth the money if you want your car to pop the whole time but dont want to buy a new exhuast.
The pops and bangs are noticeably easier to initiate, and keep going for longer during the overrun. A good improvement without going OTT.
