Yes, it is very limited though. I haven't used mine for so long so I may not remember exactly, but the graph only lets you monitor a track a few parameters from your scanner. Basically, you hook your scanner up to your vehicle and go into the capture mode. It will record about 20 seconds of data before and after your capture point. You then hook it up to your PC to download just the 4 or 5 parameters that you selected to capture. You can't re-size the graph or even do a print-out if I remember correctly. I haven't been on their web-site for a while so maybe they've updated the PC-Link software since I last used it though. The biggest problem is that the scanner doesn't work well in the capture or monitor mode on at least a '97 and '98 Explorer. Any time you do anything that takes extra processing power from your PCM (things such as driving), it will cause the scanner to loose communications. AutoXray is located about a mile from my work so I have been there on numerous occasions for them to use my Explorer for testing. I have been working with the owner of AutoXray and their Software Engineer. Initially it was thought that something might be wrong with my Explorer that was causing it to loose communications so I used my scanner on a co-worker's '98 and it behaved the same way. They swapped my scanner twice, each time with a newer version of software and the problem persists. The last time I was there, they loaded in the Enhanced OBD-II support at no charge which was when I purchased their PC-Link software. The enhanced upgrade at least makes my scanner a lot more useful. The generic OBD-II support doesn't work properly in the Ford mode for oxygen tests. The enhanced mode lets me use the Ford specific tests so I have a lot more tests that I can run now. My only complaint now about the scanner is I can't use the monitor or capture mode when driving down the road.
