Mazda MX-5 Miata (ND generation)

Here is information on some of the PIDs that you're most likely to use with RaceChrono and equations to get the right scale, etc.

These PIDs were tested on 2019 Mazda MX-5 Miata RF, but should apply to other model years of the ND generation as well. If you find any mistakes, or model year specific PIDs, please send a pull request!

Recommended PIDs:

Here are PIDs and RaceChrono equations for data channels that should be enough for most people:

Channel name	PID	Equation	Notes
Accelerator position (%)	514	E/2.5
Brake position (%)	120	max(0, 100 + bytesToInt(raw, 4, 1)) / 2.55	Might need more work, possibly a different scale
Steering angle	134	(16000 - bytesToUInt(raw, 0, 2)) * 0.1	Positive value = turning right. You can add a - if you prefer it the other way around.
Speed	514	bytesToInt(raw, 2, 2) / 360.0
Engine RPM	514	bytesToUInt(raw, 0, 2) / 4	If someone records >8192 rpms to confirm, let me know :)

Would be nice to find PIDs for ...

Essentials: fuel level, coolant temperature, clutch pedal, current gear.

Advanced: tire pressures, tire temperatures, lat/long acceleration (if available), yaw rate, individual wheel speeds.
