WindScaling difference - Newton/Isaac 1.0.10, and Isaac 2.01
Posted: Tue Mar 26, 2013 2:11 pm
There's a Wind scaling difference between Ibike Newton/Isaac 1.0.10, and Isaac 2.01.
The cal rides test below was not done in very good wind conditions, but shows Isaac 2.01 get other scaling numbers:
Cal ride # ---Newton---Isaac 1.0.10---Isaac 2.01
Cal ride 1. ---0.979-------0.976-----------0.943
Cal ride 2. ---1.001-------0.999-----------0.963 (wind changed direction a bit)
Cal ride 3. ---0.978-------0.973-----------0.937
Cal ride 4. ---0.972-------0.962-----------0.949
Avg. WS------0.983-------0.978-----------0.948
(Isaac WS number from "Check calibration")
So my difference between Newton and Isaac 2.01 is avg. 0.035, not as much as last WS bug (http://www.ibikeforum.com/viewtopic.php?f=55&t=2534),
but a difference (A Cda 0.350 -> 0.363 difference)
