I've used HomeDyno... I bought it and all. Talked with Mike Chaney
extensively, he's a very sharp guy. The biggest problem I had on my
'95 Integra was noise... everything is close together and my recording
technology is... ummm, let's just say it's not the best.
With a good recorder, I think it wouldn't be hard to get consistently
strong runs. I noticed the Street Dyno uses something else... I have
to look into that, maybe that will work with my car.
But, when it does work, it gives really good results.

Most of the numbers you have to set in Home Dyno can be approximated.
The more difficult ones (Cd and frontal area) aren't too sensitive so
you can be off and not make a big difference.
