About MHD Flasher N54
MHD Flasher is the first Android handheld 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.
→ Easy to install
Connect any compatible Android device to your car using a standard K+Dcan cable along with an OTG USB adapter, install one of the pre-purchased MHD maps and enjoy the power and performance benefits of the MHD maps by Wedge Performance.
→ 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 30 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.

FAQ
Q: Can I test the connection before making a purchase?
A: Yes, simply tap the MHD Store button. The ECU connection is checked before displaying available purchases.
Q: Does my Android device need to be permanently plugged to the OBD port?
A: No. Once a flash is performed you can unplug your device.
Q: Do I need to purchase a new license each time I flash a map?
A: No, you can ref lash as many times as needed.
Q: Is a battery charger required?
A: It is highly recommended for long flashes (install, uninstall). A healthy battery will handle short flashes (map changes) fine but the use of a battery charger remains recommended.

Top shelf!!! That is all there is to say about this app... The guys at MHD have essentially cornered the N54 tuning market with a tuning platform that is powerful, convenient, flexible, well supported, safe and most importantly affordable. If you are reading this then you must be enough of a car enthusist to care about how your N54 powered BMW feels behind the wheel and if that is true then you are just wasting time reading these reviews...Just buy it already, you will not be dissapointed.

Honest review from a true BMW fanatic. Average joe... I bought this a week ago and I got a flash error no biggie I found out when u flash ur ecu you are suppose to have a consistent flow of volts. It wouldn't start because it froze. I bought a car battery charger after it wouldn't let me return it to stock. I was stuck like the last dude here. So I install the car charger to the battery wait till its green fully charge I force stop all my apps uninstall and re install app. Now I have battery full with wall charge with app newly installed. (battery was disconnected for a day prior to this) it still remembered the last frozen flash but was able to get in again because of battery disconnect but most likely of the reinstalled app.) Bam it works back to stock. I bought the obd k to android through amazon. I'm thinking its the cable because it wont let me stage 2 flash it even though I went back to stock I'm guessing because its more complicated. I'm oreding the new cable through the pdf file with the otg like recommended and ill update from their I think the its gonna be the issue

Absolutely unreal. Was about to buy a Cobb AccessPort when I heard about this on the forums. Immediately bought all the modules and a stage 2 map pack. Never thought someone could pull off turning a phone into a one stop tuning solution, but they did!!! The first time the turbos spool up after flashing on a new map, you'll know this is the real deal!!!

Stage 1 only for a stock 335 and made a massive difference. Love it.

Aside from the awesome power you get from even the OTS maps, you can monitor many other variables including IAT and boost pressure. I was going to trade in my Z4 for a Porsche until I found this app. Instead, I went FBO with a Stage 2+ map and I couldn't be happier!

BEWARE OF WEARING OUT DUAL MASS FLYWHEEL! I did the Stage 2+ on my 08 335i with Recommended supporting Mods, Holy Crap!! There's so much TORQUE I over powered the stock dual mass flywheel. From a 2nd gear slow roll, full throttle, the clutch feels like its slipping at first than the tires break free. I did this several times and noticed no clutch burning smell. At highway speed it feels like a slingshot, in regards that it slips, then the TORQUE propels you at speed leveling off, devouring real estate. Next mod, single mass flywheel with upgraded clutch! Love it otherwise!

Easy to use. The correct cabling, battery charger/maintainer, and an android device is all you need. Read up on N54 stuff online and then seriously consider this. It was a good option for me.

I was worried about messing up my ecu, but I had no need to be. Flashed stage1+ with absolutely no problems. Car pulls really strongly now, right from the bottom to the redline. Some nice options too, limit boost in 1st and 2nd gear (needed) exhaust burble ( not needed but fun) I've never liked the kickdown and there's an option to delete that too. My car is stock and it's made a huge difference for little money. Don't worry, just download the app buy the tune and enjoy the extra horses.

Excellent, easy way to tune. Huge difference in just using the Stage 1 on a stock 535i. Gained nearly 1/2 second on 0-60 time. Much more aggressive in highway passing. Great features and very responsive to questions.

Program is designed good and really easy to use. The only complaint I have is that my phone won't work with it (oneplus 3) it's either the rom it runs or the type C OTG cable I got. Worked flawless with my extra Galaxy S... Just a follow up. I followed the link they replied with. It was just a setting I had to turn on to enable OTG. Works on the OP3 now.

This was the easiest install ever. For those of you little bitches crying about support, I got an email in the matter of 7 hours and full support. And then a reply within an hour after initial email SO dont listen to those babies crying about getting support. After stage 1 install had Cyl 1 & 3 misfire. .. YES IT WAS SCARY, but followed directions and falshed back to STOCK when it was backed up. DO NOT FORGET TO BACKUP! These guys are awesome and sure they will help me all along the way

Don't often write reviews. In this case I felt I owed it to the author/tuner. I ran a JB4 for 2 years, got rid of it because of driveability. Stg2 Map in this app makes my car feel like I transplanted a NA V8. I'm so impressed with smooth daily drivable power. Might be the best money I have ever spent. Genuinely feel I got more than I paid for.
