→ Easy to install 
Connect any compatible Android device to your car using an MHD Wifi adapter, install one of the pre-purchased MHD maps and enjoy the power and performance benefits of the MHD maps by Twisted Tuning. 

→ Keep an eye on the tuning
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. Activate the logging mode to save up to 50 monitors to a standard CSV file for later analysis. Track issues by reading the error codes, and delete them once resolved.

→ Flash your ECU back to a stock anytime, as often as you need to. No ECU backup is needed.

→ Custom tuning support
As an alternative to built-in maps, many tuners can provide advanced custom mapping for those who have higher or special performance needs.

  1. Tony Elder-avatar

    Power delivery is awesome was running 1+ OTS tune and enjoying it most of the time. But, it does have some issues. Such as throttle and boost spike at 10 - 15% throttle. Throttle surge when cruise control is active especially around 60 - 70 mph range. Last but not least, when putting car in park the engine just about dies then revs up and down from 500 - 1000 rpm. Mashing on the gas a bit to about 2500 - 3000 rpm gets this to stop though and car will idle fine. Removed tune for now until fixed.

  2. Scott Hardy-avatar

    App works well, no issues after several months of use. Generic maps seem good. Play store can cause issues for in app purchase, best to buy Google Play gift cards and use those.

  3. Alexis Ramos-avatar

    Very happy with the new update all plug play its awesome. No need to bench flash. Took only 12m for first flash :-D. Thank you

  4. K3 Sran-avatar

    OBD unlock confirmed with 2012+ N55 X1. Stage I tune successfully flashed on 2014 X1 xDrive35i. Process was straightforward, and was 4x quicker than the S55 flash operation

    People who don’t have this app don’t know what you are waiting for . From stock to stage2+ it’s amazing . All I wanted was a bit of extra power . Stage 1 was how these cars should of came out . Let’s just say it’s so addictive and best safest tune out there that I have done all the mods and have stage 2 + now . Worth every penny easy to use great features like burbles etc and customer service is a+ . You will not regret . Best tuning platform for our bmws .

    Most amazing tunning app available for E93 N55. Allows more control than other tuners for more money. Will not be disappointed with this app. As a club president we have all switched from a competitor to MHD. APP is easier to use and offers control of more features than others. We have used almost all of the apps and find they are all as easy to use with as much control. This app is under priced for what it offers. You can not buy a competitor for the price of the MHD.

  7. Andrew Ward-avatar

    Had a few ossues within the first few months due to running n26 plugs/delphi coil combo. For some reason the voltage/amp pull would wig out the the dme. However after updates has resolved itself. Love the options and updates. The application and twisted tuning maps are great for more power and daily driving use. Currwntly fbo and run stage 1+ for daily and stage 2+ for fun. Vehicle seems to get better fuel economy in stage 1+ than stock.

  8. A Google user-avatar

    Everything about this app is awesome and only it gets better with updates and new additions!! Don't cheap out.... You will probably need new sparks plugs and injectors if yours are too old. FBO status. Stage II + Do it all, do it once, and do it properly. Cheers to MHD for making it all possible!!!

  9. Chris Wells-avatar

    Great product for N55 tuning, lots of options and support. Make a bunch more HP with this tuning product from your phone!!!

  10. e e-avatar

    Great app, easy to use and flash. Note: If you're using a BEF, the monitoring feature won't work. The monitoring is only if you choose to use a full-flash. I use the app to flash a custom BEF w/ JB4.

    If you're thinking about getting mhd just go ahead and get it. Way better than jb4 hands down. Way more capabilities, consistent logging, very user friendly, read codes and reset adaptations. Well worth the investment.

    Fantastic product and support, I would not be enjoying my 2011 N55 135i on the same level without this app!!

  19. Mike Andrews-avatar

    Easy to use, effective and clear menus. Resetting adaptation was an excellent feature

  20. Shawn Sartain-avatar

    cold start issue still exists ( 2011 BMW 6spd). if the weather is warm, it still works better but if its little cold like(60F), the rpm dips too much to idle at 750 range. went back to 1.53 map and everything is normal, so I know it's not the car. have heard the same issue for other users as well but MHD wouldn't accept it for some reason. may be they couldn't reproduce this rpm dip issue.

    Awesome power

  57. Dinozavr Rrrr-avatar

    Running 1+ on my N55. Runs perfectly! Smooth start, smooth idle and pulls like a tank. Went back recently to stock to see how that felt since I've been tuned for a while... It felt like I was driving a different car, slow and sluggish. MHD is amazing, the value for power is unmatched.

  58. Dewan Wahed-avatar

    After running stage 2 + for over 5k miles, I could never turn back. My 135i is on a different level and i cant wait to go e30 soon. Thank you Justin for making this so easy for us.

  59. VALADCM-avatar

    Great app and their customer service is amazing. In less than a day they replied to my email and refunded me a service I purchased by mistake, then I was able to purchase the correct piece of software. Thank you

    Joseph Schiffman


    This tune is absolutely amazing! Best bang for your buck. Mhd if you could make a 100 octane tune for stage 2+ for California USA that would be sweet! A lot of the tracks in California have 100octane at them too!

  61. Eli Frost-avatar

    2011 BMW 135i, just stage one tune now, and it feels amazing, getting ready to go to stage 2. When is 2-step supposed to be released? I am very excited for it!! Also I heard that adjustable rpm launch control might be coming out

  62. Kojack-avatar

    Stage 1 is okay, but stage 2+ is like a whole new car. Definitely recommend full bolt on and stage 2+

  76. Alex Lerman-avatar

    This flasher is great. The tunes are smooth as silk, the support is phenomenal and the price is unbeatable. Obviously, my mpgs dropped while in boost, but the 50% extra boost pressure I got makes a huge difference. Can't wait for the Bluetooth monitoring/logging and all the extra features to be carried over from the n54 version.

  77. A Google user-avatar

    Awesome...easy to use straight making me think about doing away with the jb4 platform all together

    The team behind this app are phenomenal. Not only are they very knowledgeable, but they work around the clock to provide us with the best possible results they can produce. Justin has answered any and all questions regarding a simple ots and adjusted it to my vehicle as needed. It's not just the app. It's how involved with us the consumer is what I like!

    MHD 2+ 93 Oct - 2011 335i I'm happy with the smooth response and ease of use with the MHD flasher. Stage 2+ OTS map has dyno'd around 365rwtq on an XDRIVE, so be ready for a smooth driving car that pulls MUCH harder at all RPM's and all throttle positions.

  83. TheBoostedBob-avatar

    Works well, nice and smooth . Certainly need to get a fmic now.

    better than cobb, hope to get more flash option like in n54 app

  89. A Google user-avatar

    I had way too many inconstancies with the JB4 setup. When it worked it was nice, but nothing like this. This tune transforms the engine into an animal. I absolutely love the power delivery. I am running map 2+ the engine is much more responsive and reminds me of the M motor with lots of power. This is the Truth! Worth Every Penny!!!!!!!

  90. Steven Turner-avatar

    Very intuitive and extremely easy to use. Great value and makes an sore enjoyable car an absolute blast to drive. An essential upgrade for every N55.

  91. Riley Carson-avatar

    Phenomenal software for e9x BMW. I've been tuning for years and this is my favorite flasher and logger module.
