DME UNLOCK & FLASH NOTICE / HOW TO PURCHASE

B58 DME's must be unlocked and bench flashed by Dinan. While dealer / retail unlock and flashing tools are in development and will be available in the future, at present, two options are available:

OPTION 1: Visit a Dinan Dealer and purchase the Dinan Flash Software . They will remove and mail the DME to Dinan. We'll unlock the DME, flash the software and ship it back. They'll reinstall the DME.

OPTION 2: Purchase the tune. Send us your DME. We’ll unlock it, install Dinan software, and ship it back. The unlock process is free. Ground shipping to the continental USA is free. Follow the steps below if this is the course you wish to pursue.

1. Purchase the tune by contacting Dinan via phone at 1-800-341-5480.
2. Fill out the unlock form and select BMW under the unlock type.
3. Mail your DME to Dinan, 4800 U.S. Hwy 280 W, Opelika, AL 36801, USA, and include the last 7 of your VIN on the outside of the box along with a copy of the unlock form inside the box.

At no time during the unlocking process is the DME opened or physically modified. If the DME is flashed back to stock, it will need to be unlocked again. Also, vehicle manufacturers issue many DME part numbers and revisions throughout their vehicle lineup. As such, some DMEs may be temporarily unavailable as new parts and/or revisions are released.

CODE CLEARING: Customers doing the DME removal/install process themselves should be aware that in the case a fault code occurs, having the ability to read and erase fault codes is crucial. Failure to be able to perform this task may result in a vehicle that is inoperable. Dinan will not cover any expenses related to not being able to clear codes (towing, equipment rental, etc.).

COMPATABILITY NOTICE

BOX CODES: The B58 engine and its multitude of variants account for numerous unique box codes across various platforms. While Dinan has created files for many of these permutations, there is a chance you may have a box code that we have not seen. If this happens to be the case we will need to create a file for your vehicle. This process could add up to 7 days to the bench flash process although in most cases it will be turned around within 2 business days.

ENGINE VARIANTS: D900-B58-F-S1 (-W) performance engine software is specifically tuned to function with the B58B30M0 engine variant. The B58B30M1 and B58B30O1 engine variants found in the G chassis X5/X7/8 Series and G20 M340i among other applications are not currently supported by this release. B58B30M1 may be supported at a future date by this specific software following additional validation.
