MHD Tuning

MHD Flasher is the first Android handheld application to bring ECU tuning and monitoring to the BMW N54 / N55 engine. The MHD Flasher reveals the immense margin of power BMW left on the table with the N54 / N55 motor, 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 cable, install one of the pre-purchased MHD built-in maps and enjoy the power and performance benefits of the maps by Wedge Performance.

→ Keep an eye on the tuning
Monitor your engine behavior using a configurable gauge 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 stock anytime, as often as you need to. No ECU backup is needed

→ Custom tuning support
As an alternative to built-in maps, several tuners can provide advanced custom mapping for those who have higher or special performance needs.
