MHD Tuning APP
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.
Connect your BMW tuning app
Connect any compatible iOS and Android device to your car using our MHD WIFI Adapter Universal. The first install takes only 3-15 minutes* and any map or option change later just 10 seconds - 2 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 engine / car type, e-series cars flash slower than F and G Series cars.
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 for later analysis and log review. 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 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 our MHD+ On The Fly Map Switch, Anti-Lag, Flexfuel, Exhaust Flap control, fully adjustable exhaust burble, power per gear and many more.
As an alternative to built-in maps, several MHD tuners world wide can provide advanced custom mapping for those who have higher or special performance needs. Most record holding cars with over 1000HP are tuned via MHD.
