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.

First time at Southern BM today and it won't be my last. Efficient and quality service as I'd expected at a much more reasonable price than a BMW Dealer. The only downside, you'll drop your car off and will end up drooling over the m3s and m4s out front!

Took my e60 there, Jimmy was an absolute pleasure to deal with, very honest, explained everything in detail, and provided some great recommendations due to my individual circumstance. Can not recommend highly enough.

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.

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!

Excellent service at reasonable prices. The shop is very nice too, you almost feel like you're at BMW.
