Tesla Model 3 Rear Drive Unit Hacking

I have figured out the secret of how the immobilizer works and now it's possible to use drive units without VCSEC. Unfortunately, I can't reveal this information, otherwise a falcon 9 rocket will fall on my house, as Damien once joked.

Congratulations.

Where’s the fun in that? At least give us some clues!

If I post this info, then what will be the point of the inverter board that Damien is making now? Also I don't want to take away the bread of Johannes, his openinverter shop and so on. Sorry.

It's great that you are very thoughtful.
As for me (OI shop) I don't sell M3 boards and not planning either.

First off congratulations. I understand how it feels to see a motor turn after a long process of work. You are free to do with the information as you see fit. I know the broad strokes myself but i'm sure there are hundreds of details to work out along the way. The solution I'm pursuing is a different route with its own advantages and disadvantages. The biggest for me is the freedom to have it all open and accessible without fear or favor or concern about a booster "malfunction"

Sure its nice to make some money selling the boards but thats far from the only motivator. Depending on how things pan out i'm a week or two away from dragging my Volvo V50 M3 drive unit test mule into the barn and making it spin wheels with the prototype OI board in the inverter. I'll keep at it no matter what and all going well I'll try selling the board once I'm as happy as I can be that it works. I may decide to just make it fully opensource at that point also depending on circumstances. If there is no business case for selling the boards as various "better" solutions are available then that would make the most sense.

In any event , I owe it to myself and those who have supported me to keep going until I experience 500hp in a Volvo. Now I gotta wrestle a door latch back into the Red Arrow so I can make some room in the barn:)
