MHD Super License – BMW N55 (F-Series)

OVERVIEW

The MHD Flasher F+G Series is a complete flash tuning application for your BMW N55 F-Series. Unlike a piggyback module it performs full DME remapping while retaining all OEM safety mechanisms, which allows for maximum performance, maximum safety and unrivaled drivability.

You can install MHD at home and start tuning immediately. Download the MHD Flasher F+G Series app, connect the MHD wireless adapter to your vehicle's OBD-II port and pair it to your Apple iOS or Android device, then start the app — the initial installation completes in about 5 minutes with the MHD WiFi adapter. Further map changes take only roughly 30 seconds. You can return the vehicle to the factory OEM flash at any point, and no initial backup is required.

The Super License bundles every MHD function in one package: the Flasher license, the Monitor (datalogging and gauge) license and the full library of off-the-shelf maps for your engine.

For off-road use only.

TECH RESOURCES

Additional Parts Required

• MHD Universal WIFI Adapter — required to flash. The license is software only; you must have a supported interface to connect the app to the car. Not included with the license-only variant of this listing.
• Alternative supported interface if you already own one: ENET cable plus a Lightning adapter (iOS only), or K-DCAN cable plus an OTG adapter (Android only). MHD recommends its own WiFi adapter and cannot support third-party hardware.
• An Apple iOS 10.2+ or Android 6+ mobile device running the free MHD Flasher app — supplied by the customer.
• A free MHD account. Give us the account e-mail and the vehicle VIN at checkout; the license is bound to both.
• A battery charger or maintainer. MHD states a charger is highly recommended for the initial full write (install and uninstall) and for long writes on slower adapters.
• A DME bench unlock on late X3, X4, X5 and X6 models. MHD states that cars with the newest BMW software require a DME bench unlock to enable OBD flashing. Contact Speed Logic to confirm unlock options for your N55 DME before ordering.
• Optional — to run the FlexFuel maps you also need an ethanol content analyzer: MHD FlexFuel Kit - F Series B48/B58/N55/S55.

Installation

• MHD setup and app installation instructions (manufacturer): mhdtuning.com/pages/instructions
• MHD Flasher User Guide (manufacturer documentation) — covers hardware requirements, connecting to the car, flashing, return to stock, datalogging and the MHD+ suite: MHD User Guide
• Installation is performed by the customer through the MHD app over the OBD-II port; no workshop fitment is required.

Notes

• ** All Purchases Are Final on MHD Licensing **
  ** Activation code will be sent within 12 hours after payment has been received **
  MHD licenses are non-refundable and non-transferable. A license is linked to your MHD account e-mail and to a single vehicle VIN — tuning a different car, or using a different account, requires a new license.
• MHD does not publish a vendor part number for its software licenses, and no part number is recorded against this listing, so no PART NUMBER section is shown. xDrive is supported on all listed cars. Cars with the newest BMW software require a DME bench unlock to enable OBD flashing — this most often affects the X3 F25, X4 F26, X5 F15 and X6 F16. Confirm your build date and DME software version with Speed Logic before ordering.
