MHD Flasher N55e

MHD Flasher is the first Android handheld application to bring ECU tuning and monitoring to the BMW N54 / N55 engine. The MHD Flasher reveals the immense margin of power BMW left on the table with the N54 / N55 motor, while still retaining the sophistication of the original engine management program.
