All official rusEFI boards support automatic ECU definition file download if connected via USB, serial port or Bluetooth. Just hit 'Detect' and wait for the name of your ECU to appear.

Manual procedure

Here is how you create your first project in Tunerstudio:

First project

In order to create a rusEFI project you need a rusefiSOMETHING.ini file from your rusEFI bundle.

Your rusEFI board should also present itself as a USB storage device to your computer, containing the .ini file you need. This is the most foolproof method of making sure you have the correct .ini file.
