+# A Nix Package for Tactrix EcuFlash 
+> EcuFlash is a general-purpose ECU reflashing and editing tool that supports an [ever-growing list](http://openecu.org/index.php?title=EcuFlash:VehicleSupport) of vehicles. EcuFlash uses the [OpenPort](http://openecu.org/index.php?title=OpenPort) vehicle interface to   reflash vehicles via the [OBDII port](http://en.wikipedia.org/wiki/On_Board_Diagnostics). EcuFlash also allows you to edit ECU data (known as 'maps' or 'tables') in a human-readable format using a [XML-based](http://en.wikipedia.org/wiki/XML) definition system to translate the data. With properly setup definitions, the ROM from any vehicle can be edited. Future plans for EcuFlash include logging support / overlay, and live tuning.
