Fantastic
Best code reader there is for the engine ECU. The included maps are excellent. The data logging is reliable.Batistaqij
Idle missfire
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 asapShow lessJhotboy2nv
Doesn’t work with car on
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.MC335i
One little bothersome bug
For some reason whenever I start the auto logging feature whatever music my phone is playing is stopped. Otherwise an excellent platform and app.MWW83
Clean and easy to use!
Fantastic app. Would be even better if there was a CarPlay support for the gauges. 😍Gautam 06
Bmw n54
Hi all, just flashed to MHD stage 1 91 octane map. Starts up just fine driving a low speeds and RPM is fine as well. Once I go WOT, SES comes on, the car loses a ton of power obviously, and starts shaking really badly. MHD tool says:
-DME active codes-
29D0 Misfirings, cylinder 4
Going to flash back to the stock map for now, is changing spark plugs the only solution? Is there anything else that I need to change/look out for?
Thanks guysShow lesst55yoo n54
Great 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 areThat white n54
Connection bugs still remain
Update to v3.10 which promises to fix Reconnecting issues but sadly it just makes them even worse. I must now toggle wifi off/on on my phone before it will reconnect. Previously it would recover within about 30 secs. Going back to the days before the v10 ots maps, it never dicsonnected. How good it was when it just worked!Show lessdevocn
