Here is a big update from @[email protected]

It's time for MHD to enter the open beta state on N55 E Series! You'll find below the product description.

The app is in an open beta state. It is fully functional but may need here and there some polish. Currently only the stage 1 maps (stg1 and 1+ for acn91-91-93-95oct) are available.
It won't take long before we add the stage 2 maps, maybe a week. So long the stage 2 maps are not available, you can purchase a stage 2 license and flash the stage 1 maps. And once the stage 2 are available, your stage 2 license will be valid for the stage 2 maps.

The user guide is a good place to start, especially is you need a reliable KDcan cable (page 5 of the user guide, available in the app or at http://www.twisted-visionz.com/mhdguide).

Have fun, drive safe and we're looking forward to your feedback - both in terms of logs and driving experience. The maps will quickly evolve as we get the precious community's feedback.

================================================== ==========================================
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 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 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.

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 lose my licenses if I delete the app or the Android device breaks?
A: No. licenses are stored online by Google, you can use your purchases on another device as long as you use the same account on Play store.

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.

Q: How can I determine if the DME is directly flashable or needs a one time bench flash?
A: got to http://www.realoem.com/bmw/enUS/select and enter the last 7 digits of your VIN in serial number. Click Browse parts the ENGINE ELECTRICAL SYSTEM and check both CONTROL UNITS > MEVD1726 section. If the it says "No parts found matching your car." you have a MEVD172 which is directly flashable.
Looking good!
