The Following Screenshots have been taken from SportDyno Version 3.8.3
In this window the computer shows the available PIDs
(car channels), and the user can select
those PIDs that want to acquire. This is useful for slow protocols like K-line, to avoid low
sample rates per channel. In the example only Engine RPM and speed are selected
Battery voltage is provided by the OBDII interface, not by the car, so it consume less communications time.
After selecting which channels are going to be used in the system, these channels can be used either on the
or during the recording of the test.
This screenshot shows the following OBDII channels: battery, engine RPM and speed (dark)
Note that the data provided by this car is slow because it is based on K-line. This is the reason only two
channels have been selected. On cars using CAN or other protocols speed is much higher.
We are preparing an improved algorithm to obtain the data at the fastest speed available, and to interpolate the data
so the graphs are high quality in the next Software version.
