Are Desktop Dyno and DynoSim the same software?? I was just looking at the new DynoSim and the screens were virtually identical to the old Desk Top Dyno. I figured maybe another company purchased Desk top Dyno and renamed it? If they are different, which is better?

I do not know the exact details, but here is what I know...

Comp Cams purchased the rights to Desktop Dyno / Dyno 2000. They added a few minor updates, new colors and called it Dyno Sim (plus increased the price). They have also just recently purchased the rights to Dynomation.
