MHD F+G Series

I've been using MHD on my F10 535i xDrive for a year and I absolutely recommend it. I've had zero issues in regards to my car, although, if you have state inspections, I highly recommend flashing your car back to stock a week beforehand so you don't fail emissions.

During a quick flash the app froze. After that I needed to do a long flasg. Now I can only do long writes and no quick writes anymore... Also instead of 9-20mins it takes 50mins. Very unfortunate. The old app worked better. Update: All good for now

I've always used a K+DCAN cable and never had any problems so it's annoying they removed support in the latest version. They say it's slow but it's only a minute to tune once initially flashed. A recommendation to use an ENET cable or their own adapter would be better than removing support. Just download the previous version from the web if you don't want to buy an ENET cable or their own adapters.

It does amazing things. I have one complaint tho, I'm constantly having to re-log in and can't ever remember the password so I have to reset it and then log back into EVERYTHING. I'm still giving 5 stars tho because of what the app does to the car, although my RWD 3.0l turbo w/JB4, CAI, catless, cat back, intercooler upgrade and a few other bolt on's can't keep up with a Challenger 392 🤯🥺🤔🤫

Glad I went with MHD over the competition. Tune is amazing. App is great and customer service is very responsive. All around a 5 star company and experience.

This company goes to the far extend to insure safety to the vehicle. The reliable and stability is outstanding. If you are looking for a reputable company to trust then you've found them. From the friendly UI app to the amazing customer service, I'm continually in awe of every new update! They are always listening to the customers wants and desire. I highly recommend MHD Tuning! A++ Thank you for all the hard work you do guys

Fantastic! Easy instal and operation. Has plenty of options and maps to follow future upgrades! Was running jb4 for about 6 months on my 340i. Then I gave Mhd a try. Almost 2 years now and im never going to another. Great reliable power, options and safety all in one place.

Quick Respond to Issues. The tune itself is great and being able to connect wirelessly is great. Getting everything to connect was easier than I anticipated.

The tune is great, super smooth and really powerful. It's awesome to be able to easily load a tune at home. I've had tunes loaded by shops on other cars and it meant spending hours in their waiting room while they fumbled around figuring out software and talking to the tuning company. This took me about 5 minutes of actual work and 40 minutes of wait time, at home, where I could have a beer and do other things. Flawless process and performance.

The phone crashed on initial flash and I the app didn't want to connect to a different phone to retry, basically destroying the software of my car. Contacted support and got quick and effective help and solving the issue in less than a day. After initial install reflashing literally takes half a minute. Recommend a good phone that isn't too old and not prone to crashing. Running the stage 2+ map on 102 makes the car handle beautifully.

This is one of the best apps I've ever used. It makes tuning your BMW so easy that anyone can do it. Simply purchase an OBD cable, or the $70 MHD WiFi Adapter. The WiFi Adapter allows you to switch maps in around 20 seconds which is needed when you are running custom tunes, e-85/fueling tunes, or want to change the burble options on your exhaust. The amount of customizability is great on the app with the N55 engine! Highly recommend!

Great when it works. PLEASE PLEASE fix the need for a bench unlock 😢😭.

was going to try bm3, but didn't want to buy a bunch of extra hardware (laptop, wifi adapter to flash with mobile), didn't want to pay as much just for a flash tune. Also had MHD on my 1 series, and it was amazing. simple to use and great features (just like bm3). car runs great! Edit: it keeps getting better.. my m4 pulls so hard with the new stg2+ e85 map. Keep up the great work MHD!

Awesome Tuning Options and regular updates.

Update with latest patch: Absolutely a different M4. The linear power is sheer adrenaline!! This the tune I have always wanted. I used the Black wifi adapter to tune and it failed first time around. This I believe was an error on my part as my phone was in extreme battery saver mode. Once I turned that off, the tune took just fine. The power the tune unleashed is incredible! And the new licensing feature is genius! Old review: Awesome product, but too few updates for the S55.

Works great but there is a bug with at least stage 1 tunes where if you select automatic WITH fix for 2nd and 6th then the sport displays do not show new higher maxes like if you select just regular auto transmission. for example with the fix, the max torque readout is 360ft lbs but selecting regular auto without fix shows 400ft lbs max, please fix!

Google Play are utterly useless and put up who-knows-what barriers in their own systems that even they are not capable of resolving when trying to purchase licences within the App. So, thank goodness for Momir and the MHD team who have come through with a solution in super fast time. Excellent service 👌! The flasher works perfectly, thanks guys! Thanks for NOTHING Google... 👏

Finally was able to install the tune I was a little upset at first trying to get my card connect with Google. Google wouldn't accept it but finally I went ahead and just brought the Google play store gift cards an was finally able to buy everything. I bought the wifi connection from mhd everything download very quickly car is running great. Thanks !

So i bought the mhd wifi adaptor, plugged it in the obd, connected the wifi and used the app first time and it worked perfectly fine, flashed my f10. Took only 5-10 minutes, great. Now my problem is, whenever i try to flash again, i am able to connect to the wifi adaptor but i am unable to flash, the app says that a cable or wifi adaptor isn't detected. I tried everything from replugging, turning the wifi off/on, wiggling the adaptor but it still says unable to detect a cable or adaptor. Help!!

I was using a cable to connect for over a year and now all of a sudden it's not supported........ what's going on with this ?

I have created a new account so I can sell the account with the car, this would be easier if the dev just allowed transfering of licences for the same vin between accounts. but since they don't I had to use a new account, linked 2 credit cards, and multiple calls from Google, still won't take my money, so I can never use it. Pity the developers want you to pay twice for the same car when it swaps owners, if they didn't have this policy this would be easy. Instead I will just never be able to buy it.

Coming from the N54 version of MHD, these F series tunes are as amazing. Totally transforms the BMW engine. I've used each map stage and have loved each step - and really love these ethanol maps now. Easy to use, the optional wifi adapter makes map downloads in 30 seconds. Only flasher i will recommend to anyone.

Great design and user experience. Flashing your car has never been easier. Just wish they'd clean up their documentation regarding E85 blends and the N55 platform. Between their website, release notes and actual in app data, nothing lines up. I run the Stage2+ E30 tune but there are numerous mentions of E20 other places.

Final edit: the issue was resolved and no longer crashes, the app requires Google Chrome to be installed. After last update app crashes when I try to log in. Never had an issue prior. Samsung Note 9 Edit: I have contacted support, until the issue is resolved my 1 star review will stand until the issue is resolved.

awesome tune and app works great! MHD is on point and glad I went this route vs the competitor. their maps are on point, app is easy to use, and I love the wireless adapter.. wire was okay but becoming a hassle. for those debating on which flash tune, go MHD! especially for owners of the older PWG vehicles.

Best app for tuning easy hp and easy on the wallet! But I have had one problem so far when I was doing 50 to 120 mph the car started to shake back and fourth and it felt like it was losing power. Any suggestions on what that would be. Great app and highly recommend it to anyone wanting hp!
