When using the 300h inverter,
, can the temp of mg2, mg2 be reported on the Zombieverter web interface, ?
The "Show Gauges " button starts another Huebner page, which seems blank... am using v 2.15a ,
wondered if you have had better success.
Trying to find how to do this if possible. Thnx

I'm not sure but i thought only the highest temp of mg1/2 was reported I'll take a look tomorrow if i get a chance

Temps should be directly wired to the Zombie. No idea if the IS300h matches the GS450h temp sensor.
And yes at the moment it only takes the max temp, can possibly add variables per motor.
EDIT: also seen a few topics mentioning the GS450h temp sensors were not worked out so the interpretation is super crude

Thanks for the assistance,
Have now one tmpm showing,
If the max displays only, that is good to now..
I'll stop trying to find the other reading.
Or figure some switchcraft to momentarily display the lower one. Would be tricky to know which is which, and maybe I don't need that knowledge .

Measuring mg1/mg2 tmpm
Regarding that there is only one motor temp reported, the highest one,
Have now hooked up the temperature sensors to the Zombieverter.
Reads 13.09 °C thermal camera indicates 13.8°C on the bell housing area . This would appear to be Mg1 temp
With Mg1 Sensor disconnected,
Reads 10.9° C , So assume this is Mg2.
Will run one motor at a time next, against brakes to confirm temperature rise is looking honest.
A simple disconnect on each sensor in turn can determine which is the higher temperature, and also indicate the lower temp, ( when the higher one is open circuit) a workable result, thanks for the pointers , much appreciated.

It's been really slow going with the project lately but I'm still chipping away
I built my own controller to control the outlander charger, dc to dc, BMW f30 gear lever, brake booster, power steering and the cars canbus systems, power the Zombie as it has no standby mode and control my Nextion display but between Jamie and Damien I can now hand over half of that to the Zombie to deal with
ok maybe not half of it but the vehicle canbus, Gear lever and brake booster at least and maybe the charger
I've also been updating my Nextion display to suit the lexus setup

And I've fitted the f30 gear lever into the Z3
IMG20240112145858.jpg
IMG20240112145903.jpg
The mounting holes which I presume were for the automatic shifter were almost ideal just fitted them with some m6 rivnuts, made up a bracket and some spacers only took 30 minutes, shame it took me 2hrs to get the centre console out before I could do that
I just bought BMW F30 gearshifer, could you be having the pinout diagram of the lever, 12v,ground, can-He etc

Hi , A Question on your Throttle connections please
Re the Zombie /300h incerter/L210 trans.
Using 2.15a version,
Have been able to reuse existing BMW loom for the dual throttle BMW pedal assembly, but unable to select different from .
...[[single channel..]]....
option on the web interface.
Believe this is also so for 2.17a
Curious to know if you gave the dual throttle, working.
Thanks Woodfie

Yes running dual throttle

If you disconnect the earth off pot 2, as in a fault state, does it still work, I.e.respond to throttle input...as normal?
This is what I observed when checking. (Test at 30v HV)
And if no earth on pot 1, then appeared to run away,
I.e. to max speed at 30v ..

I'm sure someone can do better but here is my 300h inverter HV dc connector if anyone has a use for it
300h hv conn.stl
300hhvcover.stl
300hhvclamp.stl
I will be using it , thank you

you might want this then it's the dimensions of the brass posts, i did make the holes on the part 16mm and 12mm but they were really tight when i went to put them in so i turned them down slightly rather than mess with the printed part also there is an o ring at the step
also worth noting it was designed for the bmw cables which are 14mm
I'm happy to share the freecad files if anyone wants to alter the dimensions

just a little update
using this hack as suggested by Zechy the shuddering experianced using the 300h is completly gone with no obvious adverse affects I have covered approx 1000 miles like this with no issues
"Post by Zechy » Mon Jun 03, 2024 9:30 am
I found a workaround for the juddering that I was experiencing. I did a 30km test run at between 80 and 110km/h.
I logged the serial data going to the inverter (HTM) and noticed that the inverter is re-initialised when the juddering occurs. I assume the checksum ==0 because of noise on the line which then resends the 6 lines to initialise the inverter.
I commented out this line and now I have no more juddering
I compared the code with the GS450h code. The GS450h doesn't have that line of code."
The only remaining issue was what appeared to be low speed jerkyiness attributed to slop in the transmission this has again been addressed by the Australian contingent their fix is to use a non linear curve for MG1 but not MG2 not something i have neither the time or inclination to test but i have been driving using mg2 only and this issue goes away completly
I'm not saying this is what you need to do to fix the issues as they are both work arounds but hopefully will point in the right direction

Okay will create this and an option, so MG2 for low throttle and MG1 only ramps up when above an arbitrary 50% throttle.
Will also block the resetting of IS300h inverter. What did you change in code?

What did you change to stop it from reinitializing the inverter?
