MHD N55 E-series

MHD Tuning UG

About this app

MHD Flasher is the first Android handheld application to bring ECU tuning and monitoring to the BMW N55 engine for E series. The MHD Flasher reveals the good margin of power BMW left on the table with the N55 while still retaining the sophistication of the original engine management program.

→ 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.

Ratings and reviews

Yes, I have a question about my gauges not working. When I plug my phone up to my car, I click on the data logging button. It then sometimes says "contacting dme" or "if screen doesn't clear in 1 minute restart phone." I have tried all of that and the gauges show up, but they do not move when I am driving. What should I do?

Went from using only JB4 to using a Burger Motorsports BEF tune installed via this app and it changed the cars driveability 100%. Playing with burble and other options via the app are also a plus. I can't speak to the OTS maps and their quality, since I'm stacking BMS products, but I'm thoroughly satisfied with this app. Now to just get E8x/9x N55 the standing burble. :) Car: '11 135i N55 DCT Suggestion: popup notice if device isn't in airplane mode before flash to remind user before starting.

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.
