[MHD Tuning]

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.

Sounds pretty cool. I will be looking forward to 335is support!

[CarAbuser]

Interested to hear more about the internet connection requirement.

My tablet currently lives in my car. I use it for BMWhat coding and it has no data connection. Would I have to bring it indoors everyday for it to connect to WiFi and continue working?

What's the ETA for Z435i support? BQ has one as a project car now so I thought this flasher would support the Z4 out of the box.

[WilliamS]

I have the K-line cable, OTG, and android. If you need a beta guy, Im pretty well off in the area of testing. I assume this somehow uses Cobb software if you can edit the files and remove the nannies such as Ben and Ken do. Or is that too much info yet? Either way Im in for some help if needed.

Also when and were can we get the app to test the hardware we have currently to make sure it will work.

As well the term module is not hardware but the tune package itself correct?

[MasterWang]

Cool! I can't wait to try this out.
When will you post the logs, dyno numbers, drag strip run,video of app in action, etc?

[TT3 iN NyC]

subscribed. Can't wait to see results!

[N54Bob1988]

Im down for testing we well, have all the cables, very good with coding and flashing

I don't understand this

What happens after 24 hours?

Once you have loaded these applications to your android device......why do you still need an internet connection?

probably a phone-home to his server, anti-piracy measure.

Sounds very interesting. Nice that you split them up so we could flash then datalog with the JB4 app if you have those already. Am excited to see the interface you use and the results.

Sounds like you need an internet connection and then have to flash your car/monitor within 24 hours. I'm guessing it checks licenses and then verification expires after 24 hours.

Yes you would need to launch the app with an Internet connection active, then you can use the functions for 24h without Internet connection.
No ETA at the moment, but if you are willing to test a bit, you can shoot me a PM we can arrange something.

Map editing is done with Tuner Pro and the usual xdfs. The app can be downloaded so you can test test your hardware before making any purchase. The verification is done before allowing you any purchase. Yes the term Module regroups a set of software services.

I will let the past and future testers post their own reviews first. Logs and dyno numbers for the built-in maps are due for the end of the Beta.

Actually it is the Google Store services that check the purchases validity.

That's exactly the purpose, the MHD Flasher has its benefits for the JB4 users.

You nailed it better than me, I will update my paragraph, thank you!

Very cool, if I can keep myself from getting a Mustang I look forward to testing and getting what I can out of this program.

So the internet connection requirement is just to initially verify the downloaded modules or this is an ongoing requirement to continue to use the modules?

Ongoing.

So if my android device used for flashing/logging has been sitting in my glove compartment turned off and unable to connect to the internet for more than 24 hours while I'm driving and my car starts sputtering and popping check engine lights (this has actually happened to me on more than one occasion) my options are:

1. limp car to nearest WiFi hotspot
2. Park car and walk to my nearest WiFi hotspot and walk back once my device functions again
3. Have car towed to nearest WiFi hotspot

just so that I can check codes, switch maps or maybe even uninstall for a dealer visit?

If this is the case, tethering your tablet to your cell phone is likely the best option. I assume the data usage from the software will be negligible?

For many it won't be an issue as they will be utilizing their main device, which is always connected to the network, for the purpose of flashing, logging etc. For me, it makes the product a non-starter. Hopefully they figure out a way to overcome this.

hotspot tethering is another option for many.

Ok....so let's say I flash a purchased map to my car within the 24 hour time frame, but then want to do some fine tuning of that base map, on my own, using tunerpro.

If the 24 hr time limit has expired how would I upload my custom modified map? Do I need to re-purchase the flasher module for a second 24 hour period, or just reconnect it to the internet to revalidate it?
