NOTE - Right now the majority of signals have been identified using a '16 outback by palmerit.
If other users report different signals, will reformat this document.

Note - Probably have to reformat already to show testing values for different bytes within a PID (see 0xd1)

86
0xD0 = Steering angle and motion sensors
87
0xD1 = Brakes & Speedometer
88
0xD4 = Individual wheel speed sensors
89
0x140 = Throttle position, RPM
