 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?
 Steering angle | 312 | `bytesToIntLe(raw, 2, 2) * 0.1` | Positive value = turning right. You can add a `-` if you prefer it the other way around.
