Leave a Review MHD Flasher N54
Fantastic
Best code reader there is for the engine ECU. The included maps are excellent. The data logging is reliable.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 lessDoesn’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.
