Tesla Research - EV Controls Kit
After purchasing the Tesla Model S Drive Unit from EV West, this is essentially a salvaged drive unit made into a kit with a controller from EV controls, it seems there is some work to make this "ready to run" unit working.

Wiring up the Harness
Now showing CanBus signals coming from a working inverter
Motor Position Encoder
1002722-00-B CRANKSHAFT POSITION SENSOR
1002722-00-C - SENSOR ENCODER
RPM shows a value when the shaft is spun by hand after connecting sensor showing it working
Found by experimentation that the sensor wheel has 36 teeth:
This is slightly below the stator frequency due to induction motor slip.
Max speed of the motor (according to Tesla) is 18,000 rpm or 300 revs/sec.
Max frequency from sensor is 300 x 36 = 10.8 kHz.
Accelerator Pedal (APP Sensor)
Now showing accelerator position after connecting to inverter
NOTE: This did not work as the supplied diagram is wrong
This one is correct for the supplied pedal:
Brake is showing as working (red dot on the right), and we can now select "D" drive (as well as other modes).
