I've only been able to get Scan Tool to display live data from my truck once. The "Connect" button works fine, but when I hit the yellow or red buttons to monitor or record, I get an error stating:

ERR_RESPONSE/5
Response $11: "Mode Not Supporte".

I deinstalled and reinstalled EFI on my laptop today thinking the program might be corrupt, but it's still acting the same. Suggestions?

Hmmmm....seems that I need to deselect a PID before i can begin monitoring or recording. Once I do that, it works fine. Is there a limit to the number of PIDs you can select?

Yes - Stream Mode up to 24 channels
Dynamic Mode up to 36 "

Some PIDs use 1 channel, some use 2

Which PIDs are selected? Post a screen shot if possible
