Has anyone else found that by tuning the AM radio to an empty frequency band between stations, you can listen to the power pulses being fed to the motor? It is especially striking at low RPM. I am picking up audible information on what the controller is sending to the motor, and can hear when the power does a step increase as RPM rises. The regenerative braking pulses are also audible.
Is it worth asking the electronics guys to devise an antennae/filter to pick up and isolate this signal, to use as a feedback diagnostic as we drive this great car? Insight to how the controller and motor are responding to our driving inputs could improve our experience
