MHD Super License – BMW N54

OVERVIEW

The MHD Flasher N54 E-Series is a complete flash tuning application for your BMW N54. 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 N54 E-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 15 minutes. Further map changes take only roughly 60 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.

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: 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.
• No DME unlock is required for the N54 E Series platform.
• Optional — to run the FlexFuel maps you also need an ethanol content analyzer: a MOTIV N54 hardware flex fuel kit (not currently stocked by Speed Logic — contact us for availability).

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 always supported. Model years are per MHD's published N54 support list; chassis codes are the BMW body codes for those models. Confirm fitment with Speed Logic if you are unsure.
