Well before the unexpected demise of Manic Tuning in September 2019, M7 began work on developing this system to offer its customers the freedom to do their own software reflash at home without removing or disassembling the ECU. This MAXXBoost system uses the most advanced automotive software and hardware available to communicate with the advanced series of Bosch ECUs found on today’s MINIs and other high end Euro cars. By using the factory OBD (on-board diagnostic port), the MAXXBoost Handheld Tuning Tool has the ability to upload any number of standardized or customized performance tunes as well as restore the original software file back to the ECU. The unit can hold upto six tune files so you can have a daily driver tune, a track tune, a street performance tune, the stock OE file or whatever your wants are.

Based on 18 years of MINI Cooper performance experience and feedback from our large Manic Tune customer base, M7 Tuning has developed the performance files available with the MAXXBoost Tuner. Performance and power gains are outstanding.
