About: MHD Flasher is the first mobile application to bring ECU tuning and monitoring
to the BMW N54 engine. The MHD Flasher reveals the immense margin of power BMW
left on the table with the N54 while still retaining the sophistication of the
original engine management program.
Table of Contents:
Connect any compatible iOS device to your car using a MHD Wifi adapter, install one of the pre-purchased MHD maps and enjoy the power and performance benefits of the MHD maps by Wedge Performance.
Monitor your engine behavior using a configurable gauges layout to keep an eye on any of the 50+ engine monitors like oil temp, boost pressure, actual load or individual cylinder ignition timing.
Eight maps: 4 fuel octane variants, stock / upgraded FMIC variants.
Eight maps: 4 fuel octane variants, stock / upgraded FMIC variants.
As an alternative to built-in maps, many tuners can provide advanced custom mapping for those who have higher or special performance needs.
The MHD Flasher reveals the immense margin of power BMW left on the table with the N54 while still retaining the sophistication of the original engine management program.
- Flash built-in maps (purchased separately), piggyback backend maps or custom user-tuned .BIN files.
- Reset adaptation values (Lambda, Fuel/air, Octane rating, VANOS, Throttle, and Battery).
- Provides handy options like power limiter per gear, wastegate rattle fix or exhaust burble settings.
Three maps (e25, e40 and e60), FMIC+DPs recommended.
MHD Flasher is the first mobile application to bring ECU tuning and monitoring to the BMW N54 engine.
Activate the logging mode to save up to 30 monitors to a standard CSV file for later analysis.
- Backup up the stock ECU software, as fast as 3 seconds on most of the cars.
- Extensive logging values list, up to 30 values at the same time.

I personally love it, very easy to use and for not taking it to the shop and getting a custom tune does good. Would highly recommend for anyone with a 335 that they want to add a little spice to.

I recently got myself the mhd WiFi adapter and started using it and also got the iPhone app of mhd. The live logging screen keeps freezing and the write usually fails on the iPhone. It gets to a certain percent and then fails. If I connect to the wifi dongle with my old Samsung s5 it never hangs and never fails a write so I don’t think it’s the adapter I am pretty certain it’s the iOS version of the software that’s buggy. I heard my tuner tell me that he had 12 iPhone users report similar problems to him in one day! Please look into this problem as I was very excited to finally be able to use mhd on my iPhone.

I’ve been a fan of mhd and always vouched for them to countless friends to use instead of jb4.
As soon as this update happened I was excited to be able to use my iPhone. But since I tried to sign in on my tablet with the update my licenses went missing now I don’t have them on the iPhone or play store. Customer support has been basically blaming it on being incompetent in fixing this. A warning to those who got a license transfer before when you got a new car and needed the vin changed. I’m still trying to fix this issue but mhd has not been too helpful.

MHD just released a new update and I reflagged my computer in my 335IS, however, ever since this I am dropping cylinder 5 & 6 when rpms are only at 5k.
I just replaced the spark plugs and everything was perfect with the update before this last one that was just released.
Overall, it’s a great product- highly recommended if you’re looking for some extra HP and want to keep an eye on the error codes that come about.

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.

Love the tune for my 335i works excellent. Also great customer service. Accidentally bought two flasher licenses, sent one email to them and they got back to me super fast and refunded me!👍🏼

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

I own a N54, I’ve been waiting for MHDFlasherN54 for about 1 1/2 years. The day MHDFlasherN54 got announced was like the day my first born child was born. Actually scratch that....even better.

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
By Nickmam123mans
Love how mhd was finally brought to iOS but not able to flash any maps because the license won’t transfer
