It will measure the full quarter if you stay on top of the pedal until it senses that you have traveled the distance. You can also select a 30 second run (if you are looking more toward top end runs), or decelerate before the quarter and it will give the speed projected up to the end of the quarter, based on the speed when you got out of it.
I have a correction factor that I can add to make the HP figures go up. It says to divide the hp I am getting into the verified rated hp, and enter that in as the correction factor. I am running uncorrected.
I can do the tilt test to see that I get a G at 90 degrees up, down, left or right. It also has a calibration verification test that does basically the same thing. I will get a better understanding of it as I use it some more. The Subaru dealership where I get the wife's Forrester serviced will be putting in a 4 wheel dyno (if they haven't already done it since the last time I was there) and a "tuner" shop that will take all brands. I hope to get some stable readings that show my driving is consistent, what works and what doesn't; then take it in for the real dyno test and compare the HP figures to determine the correction factor.
I may get the bug enough to go to the track (50 miles away) sometime during the summer, if I can convince myself my launch and 60 times are good enough to give it a try. Somehow, I missed out on all this when I was growing up.
I will go back and read your earlier thread. Now, it will make a bunch more sense to me...
