Both MHD and BM3 support B58 now. Which one is better for the B58 engine? I know MHD has been around longer for N54/N55 but BM3 seems to have more features.

Specifically interested in:

  • Map quality and safety
  • Data logging capabilities
  • Custom map support
  • Price
  • Customer support

Currently leaning towards BM3 but open to opinions.

    BM3 for B58 all the way. The datalogging is superior and the custom map support is better. MHD is catching up but BM3 has been on B58 longer.

    I switched from MHD to BM3 on my B58 and the difference in map quality was noticeable. BM3 stage 2 map is smoother and makes more power.
