Dyno software ?

[Nick ALFANO <71amx@xxxxxxxxxxxxx>]

I agree, comparison is for adjusting an engine build
would be one of the benefits of the software. 
Accuracy of the hp and torque numbers though is the
key to doing the comparison.  If the software is to
far off or not consistent, the comparison will do you
no good and possible send you in the wrong direction.

Where are the errors in these sorts of programs? I
always thought
they were meant for comparison purposes more than
calculating
exact horsepower; like, will a bigger valve help here?
Watching
cam changes move the torque peak, etc. That seems more
important
to me than whether it's 250 HP or 200hp.

Does desktop dyno simply get the numbers wrong, or are
peaks in
the wrong place, etc?
