Yeah, I realize that after I posted. Thank you though, I'm sure you experience will be helpful to me and others.

Thanks for this post. I'm helping a friend with the electronics/software in his 996 conversion and am super interested in anything you can share about talking to the remaining electronics in the car with the DME removed. Will your code be open-source?

Or maybe their CAN HW implementation is as flakey as their software and that one extra load was too much... (full disclosure, I own an ID.4)

Your garage must be an interesting place. Hopefully, for the sake of your neighbors, for multiple reasons(!), you keep the door closed

Anyone in the USA have a non-functional AZE0 inverter? Actually I just want the external connector from the logic board so a dead logic board would be ideal. This is to add to an OpenInverter control board so I can save the original controller in my inverter.

From various reverse-engineered components not precisely sticking to standards I think you're better off on the Nissan Forum (https://openinverter.org/forum/viewforum.php?f=4) for this bit - as this thread is on the updated hardware.


Yeah, that was just an example (one I'm interested in). But ...

Damien, I've been studying your schematic and I'm a little confused about the CAN1_WAKE_OUT signal. Probably I'm just confused but I'm not sure this will work the way you have IC18 wired. The TJA1043 spec and the AH1014 app note say that the INH output will have the following values in the two low ...

Ok guys, I'll do the work :-) And I promise to document all. Was just starting the lazy way.

[At the moment] in my conversion - which I need to update here - I'm planning on replacing the Leaf inverter brain board with OI and I'm designing an "Integration ECU" around the Teensy 4.1 to handle the ...

I want to do a better job than Nissan does charging the 12V battery in my EV conversion. To do this I want to control the DC-DC output voltage (based on a charge algorithm with 12V Battery voltage, current and temperature as input). This is a Gen 2 PDM so the command is via CAN. I know it can be ...

@bapshago ~ what is the basic PWM frequency you use with the Leaf cooling fan module?

oh, of course! But that didn't fix it either. No worries though. I'll keep digging as time permits. I want to learn these code bases.

I was mistaken. My friend put a SDU in his car. But, even with the known issues of openinverter in the SDU, he's game to try it. We'll probably buy in the US from ...

OK, thank you. I'm going to see him today and we'll chat about changing from a commercial ($$$) VCU to Openinverter.

I tried to move to USART2 but no go, not even my "hello world" printf at the beginning of time. Here's what I did to re-arrange the GPIOs. Am I missing anything obvious?

1. In stm32 ...

OK, it's running! I think I must have damaged PB11 (USART3 RX) and that's why the serial IF doesn't work. I was able to print things from within the code (thanks for implementing putchar() so printf works!). This lead me to try the CAN interface with Dave's Openinverter CAN tool which worked ...

Thanks for the responses. Here's what I've done based on them, but unfortunately still no-go.

1. I tied CAN_TX (PA12) to CAN_RX (PA11)
2. I tied MPROT (PA3) to 3V3 based on Johannes's HW Rev 3 Wiki page (to be unused)
3. I tied the now REServed input, previously EMCYSTOP, (PC7) to 3V3 also based on ...

I am interested in playing with the openinverter FW with an eye towards using it for my friend's LDU based Porsche conversion. To that end I decided to just get some experience with the code and have tried to load it on a Nucleo-F103RB board. I am using the current (as of Dec 7 2026 dowloaded from ...

Nice build! I'd love to hear about your battery pack. Are you using the Ioniq5/EV6 modules? What BMS? Did you cool them?

@jetpax ~ I saw your post in the Open Inverter Web Interface Fork. It looks like your software is quite amazing. But how does one go about acquiring the hardware? The repo contains PDFs of the schematic and a board render but as far as I can tell, nothing else. Will you be releasing this as Open ...

That would really be something...

Didn't Dala do that? Put a 160 kW inverter in his Gen 1 car.

Have you seen https://github.com/dalathegreat/leaf_can_bus_messages ?


Yup. I've got that downloaded and have been through it many times :-)


It's likely an add-on afterwards, but given your background do have a look at OpenCarwings: https://github.com/developerfromjokela/opencarwings.
The ...

Maybe some of the following things will be of interest to people here.

As I mentioned I want to re-use some Leaf components that haven't normally been used. This will take some CAN bus reverse-engineering (on top of the wonderful work that has already been done and documented). Originally I thought ...

Sorry. Here's the messy setup:

IMG_2481.jpg

It comprises all the electronics except inverter/PDM/battery. You can see the brake booster isn't connected to the pedals. When I apply 12V the brake booster becomes functional as seen in the video I link below. There is a potentiometer attached to ...

What do you mean? The pedal is normally connected to the threaded rod (on the right in the picture). Opposite is the master brake cylinder. What exactly does your experiment look like and what have you connected electrically (pin assignment)?


I didn't have room in my table-top setup to connect ...

I have one too (from a 2017) and would like to use it in my conversion but I'm a little afraid it won't fit. I have it on my lab bench test setup. I haven't yet been able to make that system successfully power up in drive mode but when I press the brake pedal (which is physically disconnected from ...

I and another EV converter are sharing an Ioniq 5 battery pack for 2 400V packs and I'm wondering if we can re-use the 8 CMUs we have as part of the BMS.

1. I think there's some work going on for the Kona CMUs but not sure if anyone is supporting these CMUs. Are there any open source controllers ...

Hello, after buying my first new car in decades, a locked-down OEM EV, I caught the EV conversion bug. I've been doing the usual forum reading, github perusing, document downloading and youtube video watching and have started to convert another car I already own. I am an embedded systems designer ...
