MHD N55 E-Series

MHD Flasher is the first iOS mobile application to bring ECU tuning and monitoring to the BMW N55 engine for E series. The MHD Flasher reveals the good margin of power BMW left on the table with the N55 while still retaining the sophistication of the original engine management program.

- Easy to install
Connect any compatible iOS device to your car using our Wifi adapter, install one of the pre-purchased MHD maps and enjoy the power and performance benefits of the MHD maps by Twisted Tuning.

- 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 50 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.

- 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.
