Tune your engine with your Android or iOS device
Unleash your Engine
MHD Flasher is the first Android and iOS handheld application to bring ECU tuning and monitoring to the BMW N54, N55, S55, B58, S58, S63 and N13 engine.
The MHD Flasher reveals the immense margin of power BMW left on the table with the N54, N55, S55, B58, S58, S63 and N13 motor, while still retaining the sophistication of the original engine management program.
Keep your distance
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*.
You can flash your ECU back to stock anytime, as often as you need to. No ECU backup is needed.
*flash times vary depending on cable used and engine type
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. You can also reset various adaptions like AFR, Throttle, VANOS, Fuel, Load control and many more.
Add big power & custom flash options
Install one of the MHD built-in OTS maps and add big power to your BMW.
Select our special flash options and add features like fully adjustable exhaust burble, power per gear and many more.
As an alternative to built-in maps, several tuners can provide advanced custom mapping for those who have higher or special performance needs.
