Any of you guys experienced operators? 'Cause some of that stuff is just plain wrong.
You can do a negative run on a DynoJet and figure parasitic drag but it's not part of a roll on run. You must go into the software and select it. On some bikes it's a bad idea to do. Like a 2 stroke.
The DynoJet uses drum weight/diameter,gear ratio,RPM and time to calculate HP.
