So I Johu was kid. eough to confirm the STM32 code was https://github.com/jsphuebner/stm32-teslacharger .

I downloaded and compiled the code and tried to upload using the wifi interface but unfortunately no luck.

Looks like I'm now facing the "Communication problem. between ESP and STM" issue ...

I'm not sure if I have the original or Johu's updated one. Where do I find Johu's?

The name of the one I used is Charger_Gen2_V5.bin or .hex.

Okay. So I was able to update my wifi card. For anyone curious, use the Arduino IDE 1.xx, not the latest 2.xx version.
Unfortunately, it didn't allow me to configure the charger. This is what the charger website shows now:
https://media.kijiji.ca/api/v1/ca-prod-fsbo-ads/images/3c/3c4d6f82-0716-4e32 ...

That worked! Sequence is important. Thank you again!

But it didn't do anything to get me access to configuring my charger. :(
In Damien's instructions in the the manual, it refers to making a serial connection to a USB port on charger board but I guess that was phased out when the wifi card was ...

Hi Guys,
I feel really stupid, but I tried connecting the ST-LINK programmer to the STM32 "Blue Pill" and it worked fine. But when I tried to connect the ST-LINK programmer to the charger board, it didn't detect it. The programmer just shows a red light flashing. Is this what I'm supposed to be ...

Doh!! Labelled “Programmng Port”. Boy do I feel stupid… and grateful. Thank you! So then I can configure the charger here via stm32 programmer. Do I still need to update the wifi board?
Thanks again!!!

Here you go... I removed the wifi board currently because I'm trying to program it.

I bought the board locally from someone that bought it from Damien I believe as I have the envelope it was sent in and I it has his info. So I agree it’s probably not running the latest interface or firmware.

I’ve ordered the Wemos D1 mini board to program the Olimex MOD-WIFI-ESP8266 wifi card and ...

Hi Everyone,
Just have a quick but maybe stupid question on getting the charger configured. I know in the instructions, I need to use the STM32 programmer, but on the youtube video, as soon as you apply 12V to the unit, you can connect to the config panel by connecting to the charger wifi network ...

Originally, I wanted to get a SimpBMS but saw that the EVS-BMS was a newer version that replaced it. But I can’t find anywhere that has it in stock, much less one that is willing/able to ship to North America (Toronto, Canada specifically). Anyone have any suggestions? I suppose I could get the ...

Well it’s been an interesting time of late… When I first completed the conversion give or take a few small issues, the car ran faultlessly for a year or so, which certainly led me into a false sense of security, as over the past four months it’s just been one challenge after another.

The biggest ...

SUCCESS!!!!
After months of waiting for parts, replacing bearings and seals and then wiring everything up, the used motor that I bought 5 months ago that I had no idea whether is functional, actually spins!

Two things I ended up doing:
1. Needed to increase the boost value from default is 1700 to ...

Thanks everyone for the responses. I did recheck/test everything as per the video. All initial meter readings on the inverter were fine.
The board is getting power and when I turn the axles manually and plot the speed it registers so I know the encoder wiring and connections are also good.
Again the ...

Hi Everyone,
I'm reaching out to get some troubleshooting tips on getting my LDU too spin on low voltage. Here's where I've gotten to:
- Openinverter board connected to LDU powers up fine and I can get to the home page.
- Using a 30V 10A bench power supply for HV testing and a freshly charged car ...

No, I mean the 30V power supply....

Thank You! But do I just not make the connections on the 23-pin connector to the contractors? And will a 30V/10A powersupply be enough?
On the 23-pin connector, I've connected:
Pins 1, 7 (and 23 once for starting) for 12V+
Pin 11 for ground
Pins 9, 10, 16, 17, 18 for encoder
Pins 12, 13, 15 for ...

Hi Everyone,
I've been reading up on this form and will be starting a build thread shortly. I've rebuilt my LDU with the openinverter controller board.
I've so far been able to connect 12V power to it, get into the interface page and calibrate my throttle pedal. I've also connected the encoder lines ...

Just to document what I did (in case anyone has the same question): There is an excess of grease in the female spline of the primary gear that fits on the end of the rotor shaft that gets pooled up on the surfaces where it’s not used. I just rolled the shaft around these surfaces and used that. The ...

Okay. Got the rotor back in and end plate on but not the coolant seal and cover yet. That's enough for tonight. In the future, does anyone know what kind of grease goes on the spline end of the shaft?

Thank you both!! This is invaluable information and advice. I'll post everthing in my build log when I'm ready.

Thanks again to this community.

Hi Everyone,
I've been combing through all these pages, Howard's site and Johan's youtube videos (thanks to everyone who's contributed to this body of knowledge!) and need some tips. I've disassembled my LDU and am now in the process of re-assembly after waiting months to get new seals (Chengming ...

Axles:

A relatively major milestone.
After some/many hours of measurement and trolling thru various online catalogs, I managed to find some suitable CV axle shafts.

For Stub Axles, I purchased the Zero-EV 930 stubs during my mockup phase as I knew I wanted to stick with as close to a factory ...

Thank you. I'm in Toronto. And thanks to this thread and many other threads on this forum, I've established that I'll be using the Tesla LDU with the reverse oil pump. I'll get into more details in my own thread, but general thought is I'll also use some Chevy Volt gen 2 batteries and a Tesla ...

Hi All,
Finally found a car that I'll be starting this on... '06 Cayman S with a bore-scored engine, but only 67k kms (not miles!). As I start re-reading this thread and preparing a list of things to buy, I'm looking for advice on what driveshaft parts I need and how to source. Do I need these from ...

Sorry, one other question: Do you need the ECU/DME for the engine attached/connected?
