I've found this software: http://www.charm.net/~mchaney/homedyno/dynokit.htm
for purchase, and this software for free
FWIW, I have used neither (been too busy changing head gaskets...). In
essence, this is all the "big" dynos use when you pay them all that money
(Sort of). Instead of a water jacket or other load, this software uses your
vehicle as a load....
I thought I could fudge the vehicle numbers (but leave them static) and just
compare between jet settings, ignition timing, etc.
