Solved the problem. Pinning from the resolver to the inverter was not correct (I made a mistake when I transferred the wiring information to an excel sheet, and then only checked the pinning against this wrong sheet...).

30V and approx. 1,5 Amp was enough to get MG2 to spin. Cables from the ...

took three 12 V lead-acid batteries and connected them in series (36 V) as HV power source.
Basically same behaviour, the output shaft just rattles / shudders but does not spin.

I just realized that "idc" shows a negative value, is this correct or did I switch polarities?

here is a plot with idc ...

one more question, just found in my notes that there should be 60 Ohms between each sync serial wire pair (e.g. between CLK+ and CLK-) as a check if the wiring is ok. Cannot find the source of this information any more, I think it was in one of Damien's videos.

Where to measure that, is it the pins ...

set MotActive to MG2
set regenmax to 0

Show all your spot values with the Zombie in RUN mode. Just save the webpage as pdf via print.

Yes, spinned the flange by hand as fast as I could, probably 60 rev / min... Plot showed Zero.
Inverter was in run mode.

Please post your params so I can go through and tell you what to change.

Does the output shaft spin freely by hand? Are you trying to spin 2 motors at once of have you set it to spin just MG2?


attached are my parameters.

Yes, I can spin the shaft by hand, have to overcome an initial ...

somehow I`m not getting further.

I have several issues:

The WIFI connection to the interface seems to be quite unreliable, sometimes parameters are not displayed, I have to reload the page often. Quite annoying, can I connect the Zombie via cable to my laptop to avoid having to use WIFI ...

Hi Tom, could you elaborate how to check the "reported speed from the Inverter"?

Any more hints which video / context this was? Damien published quite some Videos

Checked all wirings, pinning is correct.

Wiring for Motor phases is stock, resolver wiring and communication between Zombie and ...

Yes thats it, get some lead acid batteries in series or something. Also it seems to drop alot from the shunt to inverter, you clearly wired it very poorly with unsuitable cables.


Changed my wiring between power supply and inverter to 10mm². That must be more than sufficiant for 5 Amps ...

here's two plots.
The Voltage from the power supply collapses drastically when I push the throttle.
Seems the power supply is too weak?

OK, partial success. Found a broken wire / loose contact between Zombieverter and Inverter.
Now the Inverter is up, yet when I press the throttle the motor(s) is only shuddering and doesn't spin.
Could this be due to wrong settings or is my Power supply too weak (5 A at 60 V)?

Okay, show us pictures of all your wiring.

You need inverter comms to work first.


Here is a diagram of my wiring:

The Inverter B1 is wired via a relais (controlled by the Zombieverter).
What I meant is that the control via Zombieverter works and I have 12 V on the Inverter.

Post your params.

Do you see any info from the inverter? invudc tmphs ect.

Did you wire it up according to the wiki?


yes I wired it up according to the information I found on the wiki / forum here.

The two resolvers are connected, but temperature sensors from the two motors are not ...

thank you @Tom91 and @Jacobsmess.
I managed to initialize my ISA shunt, although the namings of the parameters mentioned in the procedure of the "ZombieVerter VCU" Wikipage do not match any more. I assume they changed when the console was updated. If I knew how to edit the Wiki I would update the ...

Hi all,

I am trying to get a LS210 gearbox with matching inverter from a GS300H to run on the bench with a Zombieverter.

I have a Zombieverter with a calibrated throttle pedal wired up. I want to use a 60V bench power supply for High Voltage, apparently that's enough to get it to spin.

Now I ...

The back of my wired connector. Note I have left out one of the resolvers as this was for a test setup for Zombie testing.


Hi Tom, is it required to connect all four pins of the voltage supply (+B and +B2)?
I think I saw in Damien's GS450 / 300H video that he connected only +B2 and ...

Hi all,

I have a L210 with matching inverter sitting on the bench and want to get it to spin. This transmission will likely not make it into a car any time soon, but I want to assure that it's basically working.
I saw in @andypbowell 's video that you can get it to spin with a 60V power supply ...

Hi there,

I have a Zombieverter that I purchased quite some time (years?) ago. It sat on the shelf, but now I want to use it. I wired it up, the ACCTY LED is flashing, but I do not understand how to get access via Wifi.

There is a thread about problems with the ESP8266 Wifi module but do not ...

any chance you have the partnumber of the wire loom?

I was looking for a used loom, but without the proper partnumber it's almost impossible to find one...

Hi Pete,

thanks for your answer. If you know what to look for you can indeed seen a chamfered edge on one side.
Would not have recognized that as an indicator, I was only looking for a dot...

Hi everyone,

I am currently assembling / soldering the remaining components onto the VCU (Zombieverter) board and have a problem, I do not know how to orientate the gate drivers on the board.

The printing on the actual parts is "3122T HATL", but there is no dot or anything that gives an indication ...

ok... thanks.
Was hoping it would be 3,45.
I am thinking about converting a small / light 4x4 car: a Suzuki SJ410 / SJ413 (Jimny/Samurai/Katana or whatever they were called in different markets).
I like the idea of getting rid of the combustion engine including gearbox and transfer case ...
