It's good to have known correct units for the driver input torque signal. However:

  1. You switched to a new signal; it's very important to reference the same signal in Panda safety
  2. Having re-scaled the signal, you also need to re-scale the driver input threshold in openpilot
  3. You will need corresponding scaling and driver input threshold updates to Panda

In short, this is the beginning of a valid change but needs additional work, including a companion Panda PR.
