How do I connect my Speeduino to Tunerstudio?
Step 1. Figure out what firmware is on your speeduino. You can use this guide.
Step 2. Download, install and open Tunerstudio.
Step 3. On the main screen, click “Create New Project”.
Step 4. In the name field, put whatever you want. Leave the project directory alone.
Step 5. In the firmware section do not click detect. You will waste your time. It doesn’t work. Click “Other/Browse” and navigate to the Speeduino.INI file for the firmware you’re using. You can download the appropriate INI file from the speeduino firmware wiki. The SpeedyLoader software will also have an INI if you’ve used SpeedyLoader to update the firmware.
Step 6. Just keep clicking “next” through all the windows to select all the default settings. Default gauge layout, default units of measure, etc.
Step 7. Once you see the grayed out gauge cluster with “NOT CONNECTED” across the top, click the Communications dropdown box and click “Settings”.
Step 8. Change the COM port to whichever COM your Speeduino connects to. Usually it’s COM4 through 10. COM1 is the Windows default. It’s probably not COM1.
Step 9. Do not click “Test Port” or “Detect”. They don’t work. Just click Accept.
Step 10. After a few seconds, you should see a loading bar show up across the top as Tunerstudio loads the tune from the Speedy.
