MHD Flasher N54

The app is easy to use and functions are straightforward. It’s so nice being able to flash your DME through your phone. The process is simple too. No complaints yet.

Best-tuning platform for BMW

pls make one for m54 for the e46

I think mhd is a great product I have both the Cobb accessport and mhd n54 and I have to say after comparing the 2 the idle on my Cobb map is much much smoother… Everything is brand new plugs injectors no boost leaks… and for some reason with v10 map I’m experiencing idle hiccups… I’m very disappointed with the idle on these maps and needs fixing asap

I can use it in acc mode but cannot use it while engine is running. I’m able to flash maps and reset codes but not monitor even after buying the package for it on their website and after sending in various emails I have yet to get a reply.

Why do I have to wait 24 hours to get my tuning license it should be instant SMH 🤦🏿

For some reason whenever I start the auto logging feature whatever music my phone is playing is stopped. Otherwise an excellent platform and app.

This app is amazing but my beemer is a piece of doodoocaca rn but y’all should add like a 0-60 60-120 timer so we can see how fast our beemers are

Ever since I updated my MHD I been having a misfire in cylinder 3 and I Chang everything and it keeps doing the same thing no matter what I do that the only cylinder I get a misfire in. Is anyone else having this problem if so what did u do yo fix it.

no reason to not have MHD. can’t think of one
