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 any compatible Android device to your car using or MHD Wireless Adapter or a KDCAN Cable. The first install takes only 2.5-12* minutes and any map or option change later just 19s – 1.5 minutes*.
*flash times vary depending on car, engine type and adapter used.
*flash times with KDCAN cable are around 15-40min (initial installation) , 1-8min (map switch)
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.
As an alternative to built-in maps, many tuners can provide advanced custom mapping for those who have higher or special performance needs.
Set your desired exhaust burble (duration, aggressiveness, min rpm, min speed) and enjoy the sporty sound of your N13 powered BMW.
Suppresses the raised idle rpm at cold start phase.
Prevents the AT/DCT transmission from downshifting when pressing the kick-down switch at full throttle.
Select different coolant targets for optimized cooling and performance. Sport Mode for spirited daily driving, Race Mode for drag racing (maximum cooling).
Improves the 1-2 second lag some people experience when shifting fast (manual transmission).
Change the position of the wastegate arms during idle/decel to mask the rattling noise.
To prevent wheelspin, limit the power in the first 3 gears to your desired level.
Remaps the pedal to throttle mapping for a more linear torque request than stock.
Select your desired minimum idle rpm speed – less rattle noise with single mass flywheels.
