MHD User Guide

MHD Flasher is the first mobile application to bring ECU tuning and monitoring to multiple BMW platforms. The MHD Flasher reveals the immense margin of power BMW left on the table with these engines while still retaining the sophistication, smoothness, and safety of the original engine management program.

MHD Flasher is not only very simple to install, it also makes it easy to keep an eye on the tuning and your engine. You can flash your ECU back to stock at any time, and as often as you need. With support for mostly all Android and iOS devices, download MHD Flasher from their respective app store and get started today!
