 # FT86 cars (Subaru BRZ, Toyota 86, Scion FR-S)
 
+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.

 ## PID 0xD0

+Speed | bytesToIntLe(raw, 0, 2) * 0.01569358787 | May want to check the multiplier against an external GPS device
+Brake position | min(C / 0.7, 100) | The third byte is the pressure in the brake system, in Bars. 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.

+------- | -------------------
+Gear | G & 0xF | Not tested much. The value seems to jump so much that the usefulness is questionable.

+Given how frequently 0x141 messages are sent, I presume there's a lot more
+interesting info there.
