The explanation of 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.

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.
