Zombieverter or Lexus GS450h VCU that is the question. Topic is solved

Very glad to learn as to why regen was removed, seems very logical, I wish I was able to do coding for such things so I could contribute to the zombie situation but unfortunately I'll need to remain patient on the sidelines. Cheers for the info.

Crasbe does your code include gear change? As I would assume it might be a while until gear change is also included in the Zombieverter software. would love to "light up" that rear end .

I was sure the gear change code is in Zombie. Damien used it in his recent dyno run.

I think he enabled it for the dino but is unsure about letting it out in case someone drops it into first at to high a speed and the programming does not compensate. I think it is a similar reason for regen i.e. car suddenly reversing.

The functionality is there, it works, but there are two big caveats:
1) It's not currently tied to a digital input, so you can only change gear with the web interface or CAN message.
2) Nobody has successfully done at gear change on the GS450H while the vehicle is moving.

As you suggest, number two is probably the reason for number one. It needs somebody to work out how to safely do the shift while moving, probably a specific sequence that we don't yet know. Until then, it's not a particularly useful feature, but you can definitely set the gear in the web interface if you want.

Yes, I meant we changed from Zombieverter to "old" GS450H control board. May change back if the situation changes but the Zombie had too many issues that I wasn't able to solve myself.

As far as I know neither option has automatic gear change implemented. The Catphish version uses the brake (!) input to select gear, which I guess can be from the shifter, under careful control of the driver. We do NOT use that, just staying in one gear for now. If we need auto change I believe that I can implement it.

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/ ... u_throttle

Cheers this is awesome news, now I just need to work out how to get this into my ZombieVerter (I've not done that bit before)...

Thanks for sharing, I sincerely appreciate your efforts and everyone else that has contributed to this. Cheers.

Idd love to implement regen, I'm currently using Gs450h with the Zombie vcu, idd love to know if the regen code you implement on the zombie with your code works reliably, does it use Throttle to regen or the brake input?

It's worth checking Damien's video on why regen isn't included in the zombie at the moment and being sure you're comfortable with it at the moment.

There is development ongoing to get regen implemented correctly, i am working on this at the moment.

Currently testing on various vehicles and setups to verify this works.

That's exciting news. Do you know when it might be released? In weeks or months? Or not sure/willing to say?

Damien is going to test it now. First tests concluded with an outlander rear inverter.

How is the test so far? Do we have regen success with the gs450?

I am planning to do some testing next week with a build with GS450h. Other vehicles configurations are also being tested by Damien, he will create a release once all testing is done.

Note the GS450h testing requires the removal of regen blocking in the GS450h code.

I'm using the zombie and I realised the firmware versions V2.04A and V2.05A are not running /inverter is not communicating with the zombie vcu after I upgrade and power cycle the vcu and retaining similar parameters settings, any other version below this works very well on my car (my car is Mercedees W124 with 77kwh battery back 360v). firmware is directly from Damiens GitHub with no modification in the Bin. File. Anyone running this two versions successfully?

Hi Joe, very interested to hear more about your w124 with gs450h running gear as I bought two gs450h packages I'm using one for the slk230 swap and was planning the other for my 1990 300ce-24 "c124" w124 conversion... do you have a build thread for your 124?? Cheers

Mike.

unfortunately I don't have a thread on this build

Others do not have this issue, please review your settings.

thanks,i figured out that my inverter motor combo was incorrect, inverter was for the GS600H motor, now got the proper inveter and it runs

yesterday I loaded the new software V2.15A aiming to also test the awaited regen and gear change for the gs450h, the car moves forward with no issues but I had very little power on reverse and the car would hardly back-up, anyone that has already tested this new release and is willing to share their parameters setting or highlight changes needed, was previously running v2.05 with no issues

There is now a throtmaxrev setting that defaults to 30. Allows you to set a lower throtmax in reverse so you don't get full power reverse.
Try increasing that.

thanks @LRBen,letme try it out
