Re: Tesla Model 3 Rear Drive Unit Hacking

Ok. Analyzer ordered.
And I believe I have those resistors already.
So the inverter needs to be near the motor with the external plug plugged in so the oil pump gets power and sends the signal?
And the 10k resistor goes nowhere but is connected to one of the channels on the Analyzer.

I can draw up the current sensor block but it would be ideal to get the torroid size, wall thicknesses, etc. If someone wants to mail me a current sensor block, even a broken one I can 3D scan / model it up and share it here. I'm in Connecticut USA, PM me.

Re: Ford Eluminator- have you got yours working?

For 1500 without an inverter, and no support from aftermarket for decent prices. Other motors are better options. You can get a more powerful m3 motor with built-in inverter for half that price. And there is a good amount of support.
