I have the Display working. The new chip, which I soldered on the board exploded, so it is beyond repair. So thanks again to Jamie for the new board. But I also got the Lilygo working with an regular can module and usb power (so you can use the Zombieverter Display without the special board).
I ...

By now I am sometimes using the Volvo. It drives very good. But the battery is a big concern. I hope to have a other battery soon, so I can start on getting a good battery in the car. Meanwhile I have got the Zombieverter Display completely functional.

The car has been inspected for the APK (annual check like the MOT).

I love driving this car, but there is much to do before I can use it as an daily driver.

Hi muelpower, can I buy a voltage measuring board from you?

On my setup I only get it working on can 1. So set the obdcan in the zombieverter to can1 and connect the display to the wiring of can 1. Don't forget to check if the resistors on the can are correct (the 2 120 ohm resistors).
I only got it working when I programmed the Liliygo with the right ...

Finaly an update on the progress. I have done a lot of things on the car. Some things made it into the video.

Thanks, that is a way better solution. :D
On savvycan I can see the ESP canlite asking for data, but no response (if only connected to OBD2can, both on can1).
I changed all can settings to can1 and tried again to connect to the esp canlite. Still did't work.
I noticed that I use version 2.20 on ...

Thanks, I got it programmed and updated via OTA (now with working spiffs). If you know what you're doing it's not that hard at all ;)
But still no communication with the Zombieverter. And when I was looking what happend on the can bus, the ground wire fell on a live 12v contact :shock: . Resulting ...

I am not even there yet. When I connect to http://192.168.4.1 I only see the command: "No SPIFFS files"
In the arduino ide it looks like there is no compatibel partition scheme (I use ESP32 by Espressif systems version 2.0.14).
On what location should I upload the spiffs.bin file? I tried 0x290000 ...

The board (with power and can module) is connected to the lilygo. When I connect the lilygo to savvycan, I can see that it is sending messages. I assume it is asking for data from the zombieverter. When I connect savvycan to the the can wiring from the zombieverter, I see also can messages.
When I ...

I wonder if it is going to work on my V50. I don't know exactly what is done to the wiring, it is certainly not standard anymore. In my experience till now, nothing is plug an play on my car :roll: . I think it would be a nice upgrade to make the wiring more back to original and have the ...

The latest release is also working when the settings are right (with the previous settings I got an memory fault). When following the setting from https://github.com/Xinyuan-LilyGO/T-Emb ... Config.png (a different partition scheme) it works.

I got the Lilygo working :D. What a trip to get there.
Trying to upload the bin files was not working for me. Problems with python, pip and esptool took a lot of time. Finally I used flash_download_tool, but I didn't figured out on what location the files should go.
But with a lot of help from ...

I'll take a board also.
Thanks for your effort to get this working.

I am making little progress. It is an very steep learning curve. :? Using Damien his can logs is interesting (not realy working like in his video). Message 0x0300410E is starting the powersteering (and a lot of lights on the display, but not the engine malfunction light (that has been removed from ...

This is a very nice solution to get the information from the Zombieverter visible, exactly what I want for my project. But it is an challenge to get this working. I got it compiled (version 1.0.0) with Arduino IDE (without any errors) but the screen stays off. After a lot of trying (with help from ...

I have the can logs from Damien his V50, these work on mine.

The issue is that I don't have a can log from the previous electric motor controller (the Magtec system) that was controlling this micro controller. Therefore I have no idea what kind of commands this needs. If i can find out what ...

Hi all,

The Original ECM from the diesel engine is still in my Volvo V50 https://openinverter.org/forum/viewtopic.php?p=81063&hilit=v50#p81063 . On the original conversion they connected an mbed NXP LPC1768 to the ECM (crank sensor, cam sensor and engine temp) and the CEM for the fuel sensor.

Progress is slow at the moment. But there is an small update.


Is it normal that the contactors close when there is just a cable connected? Cable just connected to the car, not to a charger.

I made some progress. The Volvo can move with Leaf power.

Due to the weather progress is very slow right now.

Great project. I can't wait to see it driving with this motor.
I had my driveshafts made here in the Netherlands, let me know if you need an address.

In my Volvo I don't think the immobilizer is a problem. I get the start signal. Spoiler alert: the motor is working inside the car. I can drive.
Since there is no signal that the motor is working to the can, the systems (like powerstearing and ABS brakes) are not reacting yet. There is a mysterious ...

I made some progress. The Leaf stack is mounted in the car and the driveshafts are ordered.

Right now am I working on wiring it all into the car. The big challenge I have is how to program the Zombieverter so it tells the Volvo the motor is running and the powersteering ...

It took me a long time to make some progress. I tried FOC tuning the motor. But the motor reacted very different than expected. There are more dips in the values than in the video of Johannes and Damien. Also every time I set some values, the motor reacted different.

So I have enough of the old ...

I still have issues with the communication. By now I have a separate power supply for the wifi module and the tx and rx are connected with wires. It worked for a while and than it started to give the same loss off connection. My laptop has connection with the wifi module, but the wifi module does ...
