This guide is written for the firmware released August 6th 2020. The further away from this date your FW is, the less agreement you will have in specific locations of items in TunerStudio and terms used etc. HOWEVER, the basic principles should still apply.
First things first, [download the rusEFI bundle](Download) to get your rusefiXXX.ini file and serial port drivers.
1. [Download the rusEFI Bundle](Download) to get your rusefiXXX.ini file and serial port drivers.
Install TunerStudion http://www.tunerstudio.com/index.php/downloads and MegalogViewer (the pay versions are highly recommeded). Create a new project in TunerStudio. By the way: this is not a TunerStudio manual.
2. Install [TunerStudio](http://www.tunerstudio.com/index.php/downloads) and [MegaLog Viewer](https://www.efianalytics.com/MegaLogViewer/download/) (the payed versions are highly recommended).
Most PnP rusEFI units can be powered through the USB port. So you can set it up in the comfort of your living room and have it communicate with Tunerstudio before it is installed in the car. It is highly recommended to try this approach.
3. Create a new project in TunerStudio.

Connect TunerStudio to your ECU. You will need a USB cable to establish communication between your tuning laptop and the rusEFI unit. There will typically be only one micro-USB port on a PnP unit.
4. Connect TunerStudio to your ECU. You will need a USB cable to establish communication between your tuning laptop and the rusEFI unit. There will typically be only one micro-USB port on a PnP unit.
Your laptop should give you an audible notification when you plug in the ECU with the ignition turned on. That means that it "sees" a new device connected to a USB port.
Under "Communications" -> "Communication Settings" [IMAGE] you should select the correct COM port for your rusEFI. You will usually see only two COM ports. Chances are, the one with the higher number is the rusEFI COM-port. For most cases, the selected Baud rate does not matter. If you can't establish communication, try baud rate 38,400 | 57,600 or 115,200. If that doesn't work, you may need to try a different COM port.
After selecting the COM-port (and baud rate), click on "Test Port". This should result in a "successful!" message. If you get a failed message, you need to adjust your settings. After a successful test of the port click "Accept".

With this your TunerStudio screen should come to life! You should see sensor inputs and some output values like ignition timing and dwell. Of course the values displayed miught not make a lot of sense, since your ECU is lacking a car, but at least you can see that TunerStudio and your computer are communicating.
