USB is the most common problem, but not always the culprit. I have had instances where it was indeed the RS232 cable.

However, if it is dropping on the bench, it sounds like there is another issue.

If you can post / send a COM Debug log with the drops in it, I can see if there is an error occurring or if it is timeouts.

To get the COM Debug:

- Delete your TunerStudioAppDebug.txt
- Start TunerStudio
- Check "Communications --> Comm Debug Log"
- Open your Project, connect to your MegaSquirt
- Wait for at least 1 drop out
- Close TunerStudio
- Post / Send the TunerStudioAppDebug.txt
