I hadn't tried to record since before I went to the latest version of Tunerpro with the XDF. I'm using this on a 730 ECM.

I can monitor everything and see things change. When I tried to record I get a popup that tells something about an error creating a log file.

Any ideas?

Select the log file to record to first.

got it.
Of course, I now broke one of the pins my emulation cable connector to the ECM .....hopefully I can find one locally.
