MHD Flasher is the first Android handheld application to bring ECU tuning and monitoring to the BMW N54, N55, S55, B58 and N13 engine. The MHD Flasher reveals the immense margin of power BMW left on the table with the N54, N55, S55, B58 and N13 motor, while still retaining the sophistication of the original engine management program.
Tune your engine
with your Android device
Easy to install
Connect any compatible Android device to your car using a standard K+Dcan cable along with an OTG USB cable. The first install takes only 15-35* minutes and any map or option change later just 1-4 minutes*.
*flash times vary depending on cable used and engine type.
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. You can also reset various engine adaptions with MHD.
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.
