About this app

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 MHD Wifi 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.

The MHD Flasher can be downloaded here: https://play.google.com/store/apps/details?id=com.mhd.flasher.n54

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.

This app for me has become the most useful tool for finding error codes and tuning. Easy flash tunes, easy connection, and the best part is that it only takes a few minutes to flash a tune. MHD also provides the burbles setting, which you can adjust the aggressiveness and duration to your liking. After tuning with the correct aftermarket parts, it really feels like a different car. This is the way to fbo!

Very easy to use. Great performance upgrade. Stock clutch with 100k miles didn't like the tune, but probably needed to be replaced/upgraded anyway. Like a large selection of additional options & gas maps. First flash takes ~40 min over WiFi, subsequent flashes take about ~2 min. Very cool program. Upgraded clutch highly recommended with the flash.

I love that this team works hard to give us SAFE, STABLE upgrades. I've had this for 2 years now and it works without issue. I love the gauges, but this is where they can improve. The "updated" gauge look is ok, but it could be much more modern like JB4. Also, they could realize that many use this app daily and auto open of gauges, etc. would be great. It'll only improve and eventually be 5 star. The base program is amazing though. Consider full battery registration (different brand batteries).
