I have given up on my conversion project for now

I am selling my Tesla small drive motor (front). I can offer it with the Open Inverter Board or with the original Tesla board. I had to unsolder the current sensors from the Tesla board but I can solder them back in if necessary. The motor comes with side mounting bracket and HV cables.
The motor ...

Thank you so much Tom and Royhen for your help in resolving this issue

Yes, as already explained in at least three posts above. You are not meeting two of the three conditions that must be met to go into run mode, as indicated by "status". Set udcsw to 0 and potmin to 500 ( i.e. >491 ) and it should work.

Sorry royhen99 you were absolutely right the issue was ...

I have found a screen recording when I did testing And can confirm that status was set as below
and throttle reading when not pressed as below
Could this be the reason for not going into the run mode?

Status has to be "none" to go into run mode. Ideally the throttle has to be connected and calibrated correctly, but may work if disconnected and potmin set to 0.


Thank you very much, I would like to check this. As I had to recall this from memory I may have been wrong. It makes sense as it ...

Thanks for the suggestion but I feel if I haven't sorted run mode issue the throttle calibration issue is secondary. Even with the throttle pedal disconnected it's not going into the run mode still

If I remember correctly PotPressed . I have now left the house, going on a business trip will check on my return. Will also check all signals going to the processor with DVM. Thanks so much for your help

No not at all I can plot or use gauges to show change of state for all switches and throttle no problem at all

I have just tried this - no change on refresh. I pressed show errors and it displayed a message no errors. Opmode still remains off. I have to add that this board was made by JLC PCB and I added a CAN chip and few transistors myself. But all buttons reading correctly if I look at dinStart and T15 ...

Any stored errors or reported errors in the spot values?

No stored or reported errors. For Udclim I first used default values and then tried zero as an experiment. I just tried default values the same result. What are the conditions for VCU to go into Run mode?

The inverter? You mean zombie not going into run mode right?

Yes correct sorry I didn't express myself correctly I meant VCU :(

UDCsw is set to 0 which is correct.

It is possible the Vehicle is not working right when set to classic, I will look into this. Please try BMW E31 or E46.

Are you ...

Thank you for a quick response Tom I only have Zombieverter with power hooked up and buttons I mentioned. Nothing else is connected. I also tried connecting Prius Throttle and this is working correctly as well. I can see throttle response accordingly to me operating the pedal.
I did try BMW E31 ...

Hey All

I am testing Zombieverter VCU and I am having problems with VCU not switching into the Run mode. I currently have only Ignition on connected on Pin 15 Forward and reverse on Pins 53 and 54 and start on pin 52. connections.png

I can see that all abovementioned buttons are registered as ...

I wonder what is the reason you decided to sell the Volvo C30 in the end. I like this car and was thinking about choosing this for my EV conversion. Is there any gotchas that made you sell this one?

Thank you Johannes and Royhen99. I am planning to implement the transceiver on the Open inverter board.

Thank you Johannes, but did I understand correctly that there is no RS485 implementation?

Hey Pete,

I love the idea of the external ESP 32 module. I wanted to make my own by using your design but the firmware link doesn't exist anymore. Did you move it to a different repository?

Tripmode 1 is the best idea as Catphish suggests.
As an added path to clamp spikes I use suitably voltage rated paralleled TVS in series with a high wattage 25R resistor across the inverter HV input cables as close to the inverter as possible.



Hi Peter could you share the details of your ...

Thank you for the warning I did check on another post the 45 degrees cut should be facing towards the cable.

Thank yu so much I have found the right sensor on Mouser. Damien came to the rescue.

While I was unsoldering the Hall sensors I damaged one pin on both sensors. The problem is very similar to what Damien described in this video at 10:00

I wonder if anyone had similar problem and if anyone has any idea how to fix this? Would it be possible to cut the ...

Wow this is amazing

I programmed a couple of modules including Olimex and Wemos D1 mini. I had an issue which turned out to be a cable. So I decided to make a video about it:

Post your error if it is similar to what I have experienced I will let you know how I solved it.
