MHD Super License – BMW N55 (F-Series)

Your activation code is e-mailed within 12 hours of payment during business hours.

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 takes about 5 minutes with the MHD WiFi adapter, and further map changes take only about 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, all three N55 map packs and the MHD+ custom code features.

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 cars with the newest BMW software (see Notes below). 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

• Step-by-step guide to setup, flashing, datalogging and returning to stock: Speed Logic MHD Tuning Guide (it links to every section of MHD's own 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. MHD licenses are non-refundable and non-transferable.
• Your activation code is e-mailed within 12 hours of payment during business hours.
• Each license is tied to one vehicle VIN and one MHD account e-mail. A different car or account needs a new license.
• Cars with the newest BMW software need a DME bench unlock before MHD can flash over OBD. MHD flags the X3 35i (F25), X4 35i / M40i (F26), X5 35i (F15) and X6 35i (F16) for this. See the MHD Tuning Guide for how DME unlocks work.
• xDrive models are supported.
• For off-road use only.
• Not sure? Send us your VIN and we'll confirm fitment and any unlock needs before you order.

VEHICLE APPLICATIONS

* Cars with the newest BMW software need a DME bench unlock. Years are US model years. This license covers F-Series N55 cars only; E-Series N55 cars (E82/E88/E9x/E70/E71/E84) need the MHD N55 E-Series license. Confirm your exact model and build date with Speed Logic by VIN before ordering.
