Engine dyno software. Anything good on the Internet?

I had desktop dyno posted up on moparchat, for years. And i did buy it at Supershops ( imagine how old that is) , but I believe its orphanware now. No longer supported or sold so making use of it is not hurting anyone. Can't collect royalties on something that's no longer sold, right? And you can run most software in comparability mode in windows. Right click icon or exe file and go to properties and select comparability and choose win98 or xp. My version was bought on a 3.5 floppy! Compression really affected power in that program. BG carbs stolen from Holley, professional products..stolen from everyone! HF knocks off everything the day after the patent runs out. Can you put a patent on a CNC port design, I don't think so.
