Re: [WIP] 1977 Porsche 924 with 2019 Leaf Stack

Wow, what a great build thread. Thanks for the link. I tried searching before, but must have missed some terms or something.
Now I think we might open up the leaf gear box and see what kind of bearings we have.

Re: [WIP] 1977 Porsche 924 with 2019 Leaf Stack

Thanks for the comments!

That was a great video. I feel so bad for him frying his inverter and PDM by switching the polarity. I keep holding my breath and trying to go slowly to not fry our inverter.

It looks like he went the route of installing the motor to run in reverse by switching two of the ...

[WIP] 1977 Porsche 924 with 2019 Leaf Stack

Hi all,

I'm working on a swap that will put a 2019 leaf stack in a 1977 Porsche 924.

This will be a slow build. I'm doing it with 3 other friends (we're in Oregon) and we treat it like a book club. We get together once a month and get a little more done. We don't need it done quickly and it's just ...

Re: Leaf First Spin Parameter Help

OK, I found the problem this morning. I used parts I had around to build my little control box, and turns out the pot was logarithmic, from an old audio project. So, max it was 3100, but turned half way was still only about 50. So, it was in the thotdead (potnom < %10) zone for most of the pot range ...

Re: Leaf First Spin Parameter Help

Maybe my pot max is too high, and with the little bit that I'm turning the throttle I'm not making it out of throtdead, which is set to %10. That means pot values need to be over 310 (potmax is 3100). Does that sound right?
I turned the pot about a third of the way (pretty scared of cranking it up ...

Re: Leaf First Spin Parameter Help

Here's the files. Interestingly the potnom didn't move. I don't know enough to know why it didn't move with the pot values. I'm assuming potnom means pot nominal... the value to use if both the pots pass redundancy checks? IDK. I'm going to go look it up.

Re: Leaf First Spin Parameter Help

Will do. It might take me a couple days to get back out to the garage. But will post when I can.

Re: Leaf First Spin Parameter Help

Here's the params file, and 2 can logs, plus an image of some spot values.

For inverter selection, I have Leaf gen 1. From what I've read I know the zombie works with other leaf gens, and I just assumed this was the correct setting. Is that right?

Thanks for taking a look!
I'll be looking into ...

Leaf First Spin Parameter Help

Hi all,

I have a zombieverter hooked up to a leaf stack on a bench (2019 gen3 160kw inverter). The PDM (DC-DC) has been removed from the stack, so it's just the motor & inverter. This is just a first spin test, so there's a few things missing. I do not have a shunt set up, and so I have the udcmin ...
