Due to demand we have released the Anti Social Mountune Overrun File (ASMO) for extended exhaust overrun output in Sport / Track modes (for those who really like their pops and bangs) for the MK4 and MK4.5 Focus ST

The ASMO file adds an OEM+ style overrun, the overrun will happen in Sport or Track mode and only above 3000 rpm and 50% throttle.

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 SMARTflash 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 m330 / m365 / m390 SMARTflash upgrade to be able to install this companion calibration.

This is for Manual models only
