Engine dyno software. Anything good on the Internet?

Any good engine dyno software to use on the Internet? Something that accepts head flow and cam information would be useful. I tried using the Comp Cams cam quest software but have issues with it using my Windows 7 software.

Thanks

When I go to the Comp Cams website I don't even see the CamQuest s/w anymore. Is it still there but buried somewhere on the site?
