A few things I can't make sense of:
When I run the DR's on the rear, which are a fair bit shorter than my street setup, I've noticed that the 2-3 shift happens at an indicated 71-72mph, versus 80mph spot on, in street trim. What I'm wondering first off is whether that's a math error in the computer, and I'm still shifting at 80mph? or am I actually shifting at 71mph?
This brings up another question I've been wondering: how is the speed calculated? In the old days it was a cable driven by a front wheel - I know it isn't anymore, but does it read off of all four wheels and calculate it, or is it front or rear exclusively? I'm guessing it's not rear only - otherwise burnouts would indicate speed. EDIT: as Bob points out, though - on the Dyno speed is registered, and that's rear-only...
I suppose the question comes up if your front and rear tires are different height - which tire size do you use when you set the wheel size with the Predator?
