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.

Product Information

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.

Once you have purchased the OBD unlock, we will be in touch with you to arrange a suitable time to have you booked in to have the unlock performed. The cost is fully inclusive of all labour required to gain access to your ECU/DME and perform the OBD unlock. This could take up to a 1-2 hours to do depending on the model.

Great service and super fast
I had my 2020 M340ix unlocked. It was done in under 1.5 hours. I added a MHD map while in the carpark and enjoyed testing it as I drive home. Highly recommend.

I Bought my M Performance Brake Kit here and installed today. I got my oil changed. Love the service as always. I only bring my cars to this place eventhough I live in the north side of Melbourne.

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!

Andrew Brien @ Southern BM has been helping me for years with my BMWs - he is extremely astute and has a refreshingly customer-first mentality. I trust him to do the best work and only the best!

My first dealing with Southern BM was a pleasant one. I had some springs and shocks installed and Sean was a delight to deal with. Knowledgeable, helpful and offered solutions when not everything went to plan. I would happily recommend them.
