MHD N55 E-series is an Android-based application developed by MHD Tuning UG that provides ECU tuning and monitoring for the BMW N55 engine. This program is perfect for E series car owners who want to enhance their vehicle's power and performance. With MHD N55 E-series, you can easily install pre-purchased MHD maps and enjoy the power and performance benefits of the MHD maps by Twisted Tuning. The program is easy to install, and you can connect any compatible Android device to your car using an MHD Wifi adapter.

The program allows you to 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. You can activate the logging mode to save up to 50 monitors to a standard CSV file for later analysis. You can also track issues by reading the error codes, and delete them once resolved. The program provides custom tuning support, and many tuners can provide advanced custom mapping for those who have higher or special performance needs.
