A bit late, but 5.20.R (sine) is working great for me in my limited testing so far.
But that's not surprising as my setup is fairly similar to yours (reverse rotation LDU, single Pacifica hybrid pack, fairly light car)

I updated from 5.13(what came on my board when it arrived) to 5.20R today. Oh man, what a world of difference.

On 5.13 I had low speed, low throttle surging/bucking and would hit OC at large throttle low speed every time (even with boost at 1300). The car was mostly driveable with careful throttle ...

I removed the board completely from the charger and checked again, still 70 something kOhm.

Gave up and removed the 120 Ohm SMD resistor and cobbled a 132 Ohm resistor (need to get a 120!) on the external can lines and it seems okay now (as in I see 132 Ohms across CAN H/L)

Hooked it all back up ...

No. All power sources disconnected

So state=EVSEActivate which means it should be charging but at the same time there is absolutely no comms from the chargers. The mapping bug didn't exist in v1.07.R so it must be something with the physical bus. Maybe bus shorted when soldering in the connector?


So... I'm in exactly the same ...

Uaux is not implemented on the Tesla boards.


Is this still the case?
I'm guessing yes as I get "16.43" as noted by others.
Probably not terribly high on the priority list, but it would be nice feature for a future board rev :)

Happily drove my conversion to work and back for the first time ...

Thanks for the clear schematic
I made a pull request to update the repo

I've received my V5 LDU logic board from the OpenInverter shop and as I like to know how things work I went to look at the schematics and found that the V5 stuff is on Johannes branch https://github.com/jsphuebner/Tesla-Drive-Unit/blob/master/V5/ rather than Damiens, no big surprise there. But when ...
