1. Bcus I had to find out the hard way it left me stranded when changing just burble settings from 0,5 to 0,3s and on my new Samsung galaxy a52s 5g flashing does not work at all it does start flashing and after 5min it stopsand it left the car inoperable I have to use my old Honor 9 lite Make sure that you stay on top of your device/app updates, chrome and device sync on otherwise its not working, try device restart aswell.

2. :) 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.

3. Vehicle seems to get better fuel economy in stage 1+ than stock.Flashed my ECU to get rid of an issue with the stock outdated BMW software (idle issue/throttle lag/rpm surge when coming to a stop).

4. If you want a complete OTS tuning experience MHD definitely falls short IMO.The MHD app is such an amazing tool to really give you that extra power! I had the JB4 installed already but wanted a bit more power.

5. I feel like its getting more complicated, please keep it simple, thank you.Went from using only JB4 to using a Burger Motorsports BEF tune installed via this app and it changed the cars driveability 100%.

6. 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.

7. and you don't have any option to revert to an older version, would be nice to be able to backup an older a map ,, even if its vin-locked, and restore it on a newer mhd gui version.Yes, I have a question about my gauges not working.

8. Well done MHD and keep it up... Now it's time for me to flash xHP :)MHD is the most efficient way to tune your BMW with an n55 engine, unfortunately the developer is not updating the maps very often.

9. So unfortunately if you want 2-step launch control, antilag, and other goodies (besides burble) you'll have to look elsewhere.

10. Only issue I am having is MHD not updating my second vehicle's MHD license in my iphone.

11. I bought the MHD Backend Flash for my N55 135i and the results were great! I am on the BEF mode (4/2) & on MAP 5 on my JB4 (0/5).
