Yes that is correct. The MIC4422YM are replacements for the FAN3122 as the latter seems to be out of stock in most places at the time of writing.

Gotta say folks if the aim of the game is to demorailse me to the point where I pack it in fully it's working a charm. Getting a little bit harder every morning to get up and face the day. I thought taking a break from the forum might give me a chance to recharge so have been popping back in of late...

Here are a few videos on recent progress with the M3 drive unit project :

To get to the bottom of this is going to require some slow and steady diagnostics and information. Please do the following in this order and post the information here : 1)Use unmodified code straight from github 2)Post your parameter file here 3)Run a plot of the the "torque" paramater fro...

Folks am sad to say the time seems to have come for me to leave the forum. From what I can see over much of the past year the projects I've pursued are of little to no interest to a good 98% of members if participation is any guide. I miss waking up eagerly to check the forum and see if someone in a...

Not as much as a thank you for the effort put into solving a BIG bug and testing the fix? Ok.

Can everyone please update to the latest V1.06A code here : https://github.com/damienmaguire/Stm32-vcu/releases/tag/1.06A Following a few very intensive days testing and coding by some very kind patrons we uncovered a very significant bug in the throttle handling routine. This is now fixed, improved...

correct. its a current pump. Damn the voltage and full speed ahead. found the can message today that commands the charge port lock so yay. More soon hopefully.

you can increase throtmax. I just had it set low for testing. In other news there is a big bug fix release soon thanks to some fantastic work by one of my patrons.

Interesting. That routine should only kick in if idc>idcmax or idc<idcmin. Assuming you have set those values correctly then my guess would be some number is wrapping around itself possibly due to the change from fixed point to floats as that routine has not been modified itself. as a simple test, s...

Parameter file attached from the E39.

Small update. The good old Völlig Wertlos is finally responding to CAN generated by a micro and not just replayed logs. Oh and it doesnt care what you connect to the HV wires. 360v, 12v, heating element, dead short. Its mission in life is pumping current and annoying me with its silly amount of cros...

Uploaded the new version 1.01 (Sept 22) Just started to put items together, but had trouble initiating the IVT Shunt. It's connected CANBUS 2 (pins 27,28). Found I had to change the CANBUS to CANBUS 1 in the interface to get the VCU to talk to the Shunt. Check my wiring which is correct to the diag...

Really!!!

Test with the current DM_WORK branch Screenshot 2022-11-16 103416.png Torque is actually going completely to zero. I'll try removing that "torque cut" code and see it makes a difference. With the old code (from last year) put back Screenshot 2022-11-16 104131.png Now that is an actual sof...

Hi Damien, I will try to debug this today, obviously it’s working for you so I want to start with checking if there’s any difference in code or settings: would you mind sharing the settings you’re using, and confirm that you’re using the same .hex file that you released? Also it looked like when yo...

There have been several reports of a problem with the Lexus GS450H module in the Zombieverter VCU failing to provide smooth throttle response. e.g. here : https://openinverter.org/forum/viewtopic.php?p=48603#p48603 To date in order to solve this I purchased a GS450H drivetrain, removed it from d don...

Lets try this : Do a plot of speed and torque. Speed on right and torque on left.

Awesome, DM_WORK built and loaded OK. Showing version 1.00 A Right, I can confirm that it's not really drivable now! Sort of on/off pulses as you accelerate? I can upload a video if you want. I'll try to debug this, but can you give me a baseline for what should be working: Regen: I see the new set...

I got the VCU board back from Beemer. A Fan3121 has been fitted in position IC12 in place of the NCV8461. This kit would have shipped without the NCV8461 in any event as they were not available until about a week ago. This would have fed 12v into the 3v3 line and destroyed the microcontroller as wel...
