Re: Simp BMS

Massive thanks for sorting this out Tom! I was worried that my replacement Teensy was defective. But it's all working again now with the roll-back version.

Re: Simp BMS

Has anyone used the VoltBMSV2 code yet? My Simp was constantly restarting because the watchdog wasn't updating. I got it to "work" by commenting out the cleartime block of the main loop, but I'm wondering if this version of the code is still in progress. It's possible I just don't have th...

Re: Zombieverter or Lexus GS450h VCU that is the question.

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 brak...

Re: Zombieverter or Lexus GS450h VCU that is the question.

FWIW we finally swapped out to the GS450H Inverter Controller board, and it's been night and day in terms of understanding how to set it up, adding functionality and the development cycle. For my skillset anyway! Already have working regen, a throttle map, current limit with PID control, safety feat...

Re: GS450H stops working

I’m just guessing here but it’d be worth checking tmphs isn’t too high and also that the brake signal isn’t switching on. P.S. Also check that the inverter is getting a really good 12v supply. I’ve had problems switching it on when the 12v battery is a bit weak. Thanks - I did check these and a few...

GS450H stops working

Hi all, posting here in case other GS450H / Zombie users have any ideas... This setup has been working rock solid for a year - when the drive is powered, it works fine and dependably, apart from the various control software bugs. However it has developed a fault where it will just stop after about a...

Re: Zombieverter or Lexus GS450h VCU that is the question.

Again, great that this regression is finally fixed! Thank you Damien. I still experience what seems like a hard cut on idcmax - causes hard juddering once you reach the set limit, totally smooth if you stay below it. On GS450H, 1.11.A. Is this to be expected, or am I on the wrong version or wrong se...

Zombie serial comms

I previously managed to send out some bytes on the UART3 (that is normally used for the wifi module) to try to trace and debug the code. But in recent versions, I find I can't even read the normal data output to the module. This should be 115200 baud, 8N1, 3.3V levels.. Switching back to an older bi...

Re: Zombieverter or Lexus GS450h VCU that is the question.

Yes, saw the update on github and already tried this version 1.11A- "Fix the non working idcmax param caused by move to float calcs in throttle.". So it was a bug, and was at least partly related to the line I identified in utils.c, which is now Throttle::IdcLimitCommand(finalSpnt, ABS(Par...

Re: Zombieverter or Lexus GS450h VCU that is the question.

Wondering the same thing myself, having been away from the project for a long time to work on other things, it seems that the same problems are outstanding: No usable current limit, and some bug causing violent hard cut and re-application of torque No regen Hard cut for RPM limit as well. It's accur...

Re: ZombieVerter VCU Support

The idea back then was that you create a deadzone by setting potmin to a higher value than it is at absolute minimum. However the problem is that it makes detecting a faulty throttle pedal really hard. Therefore I changed the behavior to the opposite. So if it potval is ever outside of it's specifi...

Also from the 1.06A release notes: "#Please check your potmin, pot2min, potmax, pot2max values: They are the ABSOLUTE minimum and maximum. Please set them in a way that the potval can never reach them, otherwise an error will be stored." Has how these work changed? That seems to be the opp...

That will fix the torque cut problem? Good news, we’ll wait for that and stop fiddling with it then 👍

You are right about the possability of a loose connection and I am sure you know how hard it can be to prove or find. I am using economiser contactors.

Re: ZombieVerter VCU Support

You mean like Throttle::IdcLimitCommand(finalSpnt, 5); ? Never mind, I came at it another way. -> Changed the code back to original -> checked the problem still exists -> changed the idcmax from 300 to 3000 Problem is gone (on the ramp at least). So it seems to be a scaling issue, maybe just a facto...

Re: ZombieVerter VCU Support

I agree, the CAN interfaces as set/shown on the GUI are backwards. I have the shunt wired to CAN2 as it always has been, and with this latest software, the GUI shows that it's connected to CAN1, however it clearly is getting data from the shunt on CAN2. So it needs correcting in the SW but I think i...

Wait, what's the request? CAN2, pins 27-28 goes to the shunt on the schematic (my car is wired like that), has that changed now? Is that the cause of this problem?

Now that is an actual software bug. My torque never went to zero as you will see in the plot I posted previously. So something is telling it to drop torque. from the top of my head :udcmin being hit, rpm limiter,brake in signal. Right, potnom is going to zero as well. In the utils, processthrottle ...

Torque is actually going completely to zero. I'll try removing that "torque cut" code and see it makes a difference.

Also it looked like when you...
