MHD is a complete tuning solution for your N55 engine powered E-series BMW.
This app is being retired. Please switch to our unified "MHD Flasher" app which now supports all E/F/G series vehicles / engines as well as Supra.
This app will remain as a shell to help you switch over. Additionally, some functionality will remain to read and clear engine DTC error codes, graph and analyze your prior datalogs, view your existing vehicle licenses, and access the user guide!
