It makes a lot of sense. Also, it might be something to do with my PC configuration. I have this one (the one for GM products) :

ElmScan VPW Scan Tool - P/N: 420300
The ElmScan VPW Scan Tool comes mounted in a steel enclosure and can be used with our free software to turn your computer into a sophisticated auto diagnostic system. This interface supports the J1850 VPW protocol used mostly in General Motors vehicles.

I suspect that because I am a Saturn, I am a little different from the protocol POV. But, since the ScanGauge "just works", I was expecting the Elmscan to "just work" also, so I was miffed.

If I had the time (doctor, if he has the time), I would dig into it and write my own customized datalogging interface.
