I'm having trouble reading and datalogging vehicle speed during initial vehicle acceleration with the Cycle Analyst. I think there might be a bug in the Cycle Analyst V3.14 firmware. Here is a screenshot to show what is going on.
The areas circled in orange show battery current and vehicle speed as I accelerate the vehicle from rest. The cycle analyst is able to capture battery current immediately, but doesn't capture vehicle speed until about 3 seconds after I've started. This is shown via the speed measurement instantaneously jumping from 0 kph to 12kph at 43 seconds.
The rest of the chart shows that the speed and battery current measurements are smooth and responsive once the vehicle begins moving. The issue I'm talking about can be seen by the sharp jumps in speed when the vehicle is accelerating from 0kph.
Here's are the relevant parameters:
Number of poles: 9
Wheel Circumference: 2262mm
Data Output Rate: 10Hz
Display Averaging Period: 0.08 seconds
Firmware Version: 3.14
V3.0 Cycle Analyst
Is anyone also seeing this issue? Is there a fix for it?
