### Advanced CAN IDs
Not required for most people, but if you're a data junkie like me you might
enjoy the extra insight.
Below is a table with a few more data channels that might be useful for more
detailed analysis. When adding more channels, be aware that it will increase
the file size of your RaceChrono sessions, and might negatively affect the
update rate of the more essential channels, due to limited Bluetooth bandwidth.
However, the communication protocol in RaceChrono is smart enough to optimize
Bluetooth usage if multiple channels share the same CAN ID. As a general rule,
if a new channel has the same CAN ID as an existing channel (such as "Yaw rate"
using the same CAN ID 312 as "Steering angle"), then adding it should not affect
the update rates. Adding a channel based on a new CAN ID (such as "Lateral
acceleration") will likely affect the update rates of all other channels.
Channel name | CAN ID | Equation | Notes
------------ | --- | -------- | -----
Yaw rate | 312 | `bytesToIntLe(raw, 4, 2) * -0.2725` | Calibrated against the gyroscope in RaceBox Mini. Gen1 used 0.286478897 instead.
Lateral acceleration | 315 | `bytesToIntLe(raw, 6, 1) * 0.2` |
Longitudinal acceleration | 315 | `bytesToIntLe(raw, 7, 1) * -0.1` |
