MDash Android app

Scroll Prev Top Next More

MDash is available free of charge in Google Play store and works only with Bluetooth equipped MaxxECU units.

Note: MaxxECU MINI/STREET does not have bluetooth connectivity and MDash can ONLY communicate over bluetooth, which means MINI and STREET will NOT work with MDash.



Android version

The MDash android app works on all Android devices with Android 4.2.2 A (API level 19) and newer. We recommend Android 6.0 (API level 23) and newer for best performance.

Developed using the Lenovo TAB4 (TB-8504X), tested and verified on Google Nexus 7 GEN2 and Lenovo TAB 3 (TB3-710F).

Note: MDash uses a lot of battery, please make sure to have your charger always connected.


MDash features

Use as a dash, create custom gauges.

Read and erase MaxxECU error codes.

Boost level switching.

Custom input switches.


On screen warnings.
