Setup: GS450h in an E46 with a Zombieverter

I'm using the stock throttle pedal wired up with usual min values of approx 200/400. If I put the GS450h in LOW those drop to 0/200 when I start up the car. They don't move in HIGH gear. This causes annoyance with the throttle code being angry about the ...

I'm adding support for PWM driven heaters. My particular setup is a Tesla Model S battery heater in an E46. It has a signal that is normally used to open and close the hot water valve to the cabin that I'm reading as HeatReq and letting the normal HVAC controls decide when to turn it on and off. You ...

FWIW I ported the GS450h throttle map code from the GS450h VCU software to the Zombieverter for use in my E46 + GS450h project.

Use at your own risk it bypasses most of the current/voltage/etc protection code but drives smoothly and has regen: https://github.com/streber42/Stm32-vcu/tree/gs450h_vcu ...

I just sent a PR to add OBD2 support to the stm32-vcu code: https://github.com/damienmaguire/Stm32-vcu/pull/57

I just created a custom service that maps PID to Param num and let the displaying app deal with formatting it. This was a bit tricky since there appears to be some pretty bad bugs in the ...

Thanks for the description. Looking forward to the pics.

My whole battery is on a thick sheet of plywood in the back of my touring, so nothing wrong with some carpentry :-)

I'm very interested in the battery box you've built. Do you have any more photos/designs you could share? Right now I've got the battery taking up the whole back of the car and hoping to swap for a BMW pack that will fit in the engine bay.

I have two wires coming out from each, one goes to the zombie connector and the other goes to the GS450H VCU connector. This is so I can plug in either the zombie or the GS450H VCU to run the one driveline...for testing purposes


I would hook everything up and check continuity from the header ...

Had saved a copy of the parameters that came on the vcu so even tested with those except for changing GS300H to GS450H for inverter as throttle settings were very similar.

Maybe someone see's what I'm missing? :) Good news is that when I figure this out, I have the vcu for the next project :D ...

I don't think that will work since I think it is using this as one leg of another voltage divider. So if I add another divider the resistance of that will dominate any adjustments from the pot.

I'm working on driving the fuel gauge in my E46 with the digital pots, but the datasheet says it can only take max 7V and the BMW appears to be using 12V for that signal. Am I out of luck or am I missing something?

https://github.com/damienmaguire/Stm32-vcu/pull/29 fixed the slow blinking issue for me. I think it is spending too long waiting on the SPI transfers and slowing everything down.

I've attached a bin with this fix in it. No idea if this will help with the reverse issue.

I find VSCode + PlatformIO a ...

FWIW This is how far I got with my design: https://github.com/streber42/MS43Zombie.git

Will pick back up once I get my car feature complete and I'm more confident in what the requirements are.

Are MG1/2 temp supposed to work out of the box or do I need to replace the bias resistor?

I don't think they do unless I did something wrong as mine read 6400deg c at 9 deg c.


I patched mine to limit the readings to the min and max set by the sensor so it at least stops throwing errors or ...

I ended up picking up one of these: https://www.ebay.com/itm/334207074538?hash=item4dd04b40ea:g:z-kAAOSwRLxeXwsl
and used it to build an adapter that I'm using for now with a Zombieverter VCU.

I ended up actually using the connector for 3 from the transmission to pickup the shift up/down as ...

@EV_Builder I also haven't tested the PWM yet since those ICs were missing in my kit and I don't have a use for them yet.

@johu I found that the master branch is pulling a version of libopeninv that isn't remapping the CAN2 pins. I see remap support is in the newer versions of libopeninv. Do you ...

Just a quick one - has anyone seen the OIL PUMP output working for the GS450 yet?
I get no PWM at pin 30 of the VCU or pin 40 of the STM32, when it's on and running. (Oil Pump is set to 50% in the menu)

Trying to narrow down if it's another bad STM chip problem or something else.

Thanks ...

Looks like no loader running at all. Please don't test with the boot_updater anyhow. If you reflash stm32_loader.hex and stm32_vcu.hex and then listen on /dev/ttyUSB0 with a terminal program, you should see the "2D" bootup message when resetting/powering on.


I double checked everything and I ...

Can any of you try to update a bricked board with a USB cable attached to the wifi sockets uart? Using the updater python script: https://github.com/jsphuebner/tumanako-inverter-fw-bootloader/blob/master/updater.py

I'm working on laying out the stm32-vcu circuitry on a PCB that will fit inside an MS43 shell with the right connector so you can reuse the stock wiring harnesses. This at least takes care of power, ground, various relays, throttle, brake, and CAN hookups. I'm still working out how to repurpose the ...

I am also converting a E46 Touring. You'll need to emulate the right CAN messages from the ECU to make the instrument cluster happy. Luckily Damien's new Zombieverter has the code for that: https://github.com/damienmaguire/Stm32-vcu/blob/master/src/Can_E46.cpp

I'm not quite that far, but I'll share ...

How did you connect the transmission to the driveshaft?

I have one of each and was going to have a driveline shop combine them once I have final measurements.

Does anyone know the part numbers for the harnesses that plug into the transmission and inverter?

I've figured out:
8216430040 is the harness from the battery to the inverter and is the two smaller white connectors.
8211130* appears to be the main engine harness and I think contains the ...

Just wanted to share that I managed to find all of the connectors in one place for a decent price.
