For details on how to connect to the CAN bus, as well as more information on the
information available on the CAN bus, see https://github.com/timurrrr/ft86/blob/main/can_bus/gen2.md
Special thanks to Ken Houseal for his early legwork on finding some of these
data mappings!
## Recommended CAN IDs:
Here are CAN IDs and RaceChrono equations for data channels that should be enough
for most people:
Channel name | CAN ID | Equation | Notes
------------ | --- | -------- | -----
Accelerator position (%) | 64 | `E / 2.55` |
Brake position (%) | 313 | `min(F / 0.7, 100)` | The 0.7 divider seems to be a good value to get 100% at pressure slightly higher than those you're likely to use on the track for cars with no aero. You can use 0.8 or 0.9 if you see 100% too often.
Brake pressure | 313 | `F * 128` | Coefficient taken from 1st gen cars, seems to match fine?
Speed | 313 | `bitsToUIntLe(raw, 16, 13) * 0.015694` | You may want to check the multiplier against an external GPS device, especially if running larger/smaller diameter tires
