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.

FAQ

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.
