Hi all,

in todays testing session I switched inverters again but nicely no change but that also mean I am still struggling to get MG2 to behave. I press the accelerator it just rumbles violently (setting MG2 only). If I run MG1 only I can drive slowly in the driveway but it still sometimes give the ...

Hi again,

I have been refining and testing my setup a bit more but I am still having an issue with motor juddering. Verified all LV-communication wiring with 4-eye principle. I switched from a likely RHD-Inverter to a LHD-Inverter. But the issue persists. Only change is with RHD, MG2 only worked ...

Hi together,

now where I finally got my L210 running with Toms help. I have one particular issue. It appears as if the Motors are slipping. Is this a case of Oil missing in the transmission? I tried with half a litre of ATF but it just spits it out with a lot of pressure? Is this a common issue ...

Hi Tom,

I found the "what it will take".

1. Changed the wiring from Inverter to Resolver connections from a thicker dual core to a thin gauge multi-core wire, this ensures the pins sit easier in the Inverter Plug.
2. Upped the battery size, but I guess that was not the issue
3. Rechecked all ...

Thaaanks Tom! I got further with that.

I am getting PotNom in Drive (now where there break input is disconnected...I guess I need a different break switch. :) )

reconnecting the Inverter will definitly send signals to the motor but it just beeps when PotNom is above 10% what is needed to convince ...

Thanks Tom,

Alright i tried the following and get an interesting error. First i applied all parameters manually but UDCsw always jumps from 0 to 66,… V somwhere 20v below UDC.

I reset and flashed the Hex. Earlier i updated to V2.22 via the bin.

But same result. Fresh flash, apply parameters ...

Hi Tom, so setting the value to 0 did not change anything. Also not under V2.17A

I guess the Pedal is wired correctly as I am getting Pot and Pot2

Could grounding cause this?

Will try that first thing in the morning. Thanks

Just tested it unfortunately no change.

I guess tomorrow I will do the following:

- Re-check wiring Inverter to Resolvers,
- try with the second inverter I have
- re-flash an apply Damians e46 file for parameters (is there a new loader for V2.22A?)
- pray to the ev gods

anything else I should ...

Hi Tom,

as requested.


... it feels like I am so close thanks for the help.

Hi Tom, Please find them below. ONCE with Pedal pressed and once without.

Hi again,

after flashing the newest V2.22A today and setting UDCmin to 0. + Reterminating the connection I am getting succesfull inveter whine. But I believe I am stuck at no potnom change (as so many) but all tips have to far not changed. If I start the inverter with drive direction already ...

Hi again, so I have restored the Zombie to V2.05A. Inverter gets both 12V & HV (87V). But I still do not have any communication. What version are you guys running with the GS300H setup? Is there any obvious things I should check to get the inverter to spring to life? Are Grounding issues a thing (I ...

NOTE : If you are using a Toyota drivetrain the VCU MUST BE RESET after loading new firmware or the inverter will not start.

Ah one more point how do I correctly Reset the Zombie? As this is listed as an Issue with Toyota drivetrains?

Good to know! Under 2.17 I had the same issue. But it used to work in the past so maybe I just need to go back further. Great then I will give that a try tomorrow. Thanks Tom.

Hi all,

I have been checking all my connections and parameters the last days and yet I have no success to get to INVStatus "on". I even switched inverters to rule that one out. All other things like the Relay for 12V+, direction Switch, Sbox are working as they should. Is someone able to point me ...

Nevermind it works now :/


Happy Weekend everyone,

I had tried to update my ZombieVerter via the WebUI but afterwards the paramters and spot values option are not visible. I further tried restoring the Zombie using the ST Link and cleared the memory and tried it with V2.17a and V2.20a but no ...

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.

Connector pinouts usually correspond to backs (wire sides) of connectors and so does most numbering.


Thanks Tom for the fast reply. Yes will certainly extend ...

spare black cable is for dc-dc not used in my case


So I had spend some more time trouble shooting but unfortunately the inverter is still unimpressed by my skills.

I have wired it up as shown in my drawing. Can someone find a fault? My issue is that when I have the 12v positive and GND ...

Hi Andy,

Yes correct. And that is how I have it connected.

I was referring to this section in the wiki. https://openinverter.org/wiki/Lexus_GS450h_Drivetrain

„ If you combine a LHD transmission with a RHD inverter (or vice versa) you might end up with a motor that is juddering, not spinning. IN ...

Hi together,

I tried spinning up my L210 with the G9200-30132 Inverter. The Inverter came from UK so likely RHD and the Transmission from Europe LHD. Does someone know if the same case applies like for the L110 that the phases are swapped? As written in the Wiki?
All I got in terms of live was one ...

Perfect thanks Tom

Does anyone know the voltage and current limits supported? I guess to be safe use max voltage of the hybrid pack but would be great to know if this coil be used for higher voltage applications as well. Thanks in advance.
