I had Virtual Engine Dyno and Dyno2000. Each program had its + and -. I had to replace a hard drive and shortly after ended up replacing the motherboard and processor. After that the Virtual Engine Dyno lost its key and wanted me to register it again. I never bothered as the Dyno2000 still worked and I kind of liked it a bit better. Keep in mind my copies are a decade old. I would expect a new version to be improved.

It's been so long since I used it, I cannot remember any specifics. I don't trust my memory on this, but I think it was a little harder to use, but had more capabilities. I recall putting in the same information on the two programs and comparing results. One of the programs consistently gave about 5% higher numbers than the other.

I hope that helps you out a little.
