BMW ECU/DME OBDII Bench Unlock | For Tuning With MHD
MHD Flasher is the first Android handheld application to bring ECU tuning and monitoring to the BMW N54, N55, S55, B58 and N13 engine. The MHD Flasher reveals the immense margin of power BMW left on the table with the N54, N55, S55, B58 and N13 motor, while still retaining the sophistication of the original engine management program.
The Bosch ECU/DME installed the latest generation of F-Series and G-Series BMW models are locked from the factory to prevent tuning modifications via the OBDII port. This typically effects most models with BMW software after March-2019 (M140i, M340i, M2 Competition, M3, M4, M5, M8, etc).
To enable OBDII tuning capabilities for MHD on your BMW F & G Series, the DME/ECU needs to be reprogrammed with a new patch that allows OBDII tuning/reprogramming. This one time patch is completely safe and does not alter the factory performance of the vehicle.
This in-house DME unlock service is only available for model built pre-06/2020. For those looking for a DME Unlock for BMW models after 06/2020, our FEMTO DME Unlock service can be found here.

We offer both an in house and mail in service to have your ECU/DME OBDII capabilities unlocked.

After 3 other BMW workshops couldn't fix the problem with my M3. SouthernBM sorted it. Excellent to deal with, great communication and customer service.
Seriously great service and people. Honest and fair. Would happily recommend anyone to them.
Great experience dealing with the team at SouthernBM. Sean in particular was fantastic with his knowledge, timely responses and ultimately work performed.
One of (if not THE most) professional outfits I’ve dealt with - in the auto industry or otherwise. Needless to say, all work was carried out as promised and to an impeccable standard. Thank you Sean and team - you’ve renewed my faith in the auto business!
Great blokes down there, Eric is great for those chinese speaking customers looking for either some general quality servicing or even higher end modifications. Good team of humble and honest people, will definitely be back!
