The inverter proves blown with the diode test mode and you get a red light on one of the gate drivers?
Parameters look like the bin file I usually flash, including the hidden flags.
With a good CAN connection the wifi module should be very stable by now, not sure what happened there

Interesting, I could change the sequencing so it doesn't scan 0,1,..15 but 0,2,4....15,13,11,...1 . So less potential jumps

Re: Setting max current over CAN
Wait, you're successfully running a Gen3 OI board? I.e. in Leaf Gen3 inverter.
Apart from that, if you use the new "green" web interface you can map idcmax (accel) and idcmin (regen) just like any other item.

Re: Is discharge required?
Tesla LDU even has active discharge as in without 12 V supply it discharges. With 12 V supply the discharge circuit can be disabled.

Re: Flying ADC 16 channel BMS 96S test
Great analysis, Looks to be working. What happened to 1.09 though? Looks like it was discharged too much? Also 2.00 is flickering. Is the connection good?
Maybe you could colour - code the balancing states. Also C+ and C- are the same really. Just odd cells are C+ and even ones C-

Re: Regeneration efficiency leaf gen2
Are you running with the stock logic board? It receives a BMS charge power limit over CAN, see here: https://github.com/jsphuebner/stm32-car/blob/master/src/leafbms.cpp#L113
Don't know if there are other limits. Maybe the drop-in OI board is for you? https://openinverter.org/shop/index.php?route ...

Re: Regeneration efficiency leaf gen2
I don't know of any difference between negative and positive torque. So if you found it to be 94% efficient driving in that operating point it will also be 94% efficient regenning

Re: LDU temp reading problem (not logic)
One unusual thing I noticed in the parameters is the high minimum slip (fslipmin). The default is 0.9 Hz or so, try dialing it back and check for changes.
It's certainly not a known issue. The LDU has two stator temperatures and the maximum of the two is displayed.

The design intent of V7 was to replace the esp8266 plug-in module with the soldered esp32 module. Turns out either way the connectivity is poor.

Re: [WIP] Caterham Seven - Putting the EV in sEVen
I don't think you need to worry about the intricacies of the CCS protocol. It is just a super stupidly convoluted way of controlling basically a very big lab power supply. You tell it how much current you want and at which voltage it should throttle. Two data items. And an extra one with the battery ...

Re: [WIP] Caterham Seven - Putting the EV in sEVen
Is the DC2DC set to a fixed translation ratio or fixed output voltage? If it's a ratio it should be pretty simple. Just divide the current the BMS allows by that ratio. CCS precharge voltage is the DC2DC converters output voltage.

Re: AC charging with Foccci and Zombie, not starting
I think I will change the "nothing plugged in" action to edge triggered so it fires only once when someone without lock just unplugs.
Right now it also inhbits the stateC test I guess

Re: AC charging with Foccci and Zombie, not starting
The last time I tested the ActuatorTest wasn't disturbed as long as no cable is plugged in. So testing "Lock" locks it and only testing "Unlock" unlocks it. As soon as you plug in a cable the application logic takes over. Can you check that?

Well thumbs up first for the project in general 
But same question - why do you choose an 800V motor with 200V batteries? Why not match them? The converter just adds losses, weight and a potential failure point
