MHD Tuning

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.

Great experience dealing with the team at SouthernBM. Sean in particular was fantastic with his knowledge, timely responses and ultimately work performed.

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.

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.

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!
