AEM VCU-200 anybody running it successfully

I've been watching the AEM VCU-200 for a while now, but I haven't found anyone to successfully run it besides AEM in their black mustang and when they redid the EV West van. But I am assuming that both of those took forever to work and I am not really interested in being their guinea pig.

Is anyone running this and how hard was it to setup?

I wonder how this would work with an OEM EV, would love to drop this in my Focus Electric when it comes time to do a battery swap....
I have one and I plan on using them with their Tesla drop-in board on a sport drive unit. However, they have delayed this so part far out that I will use an Openinverter LDU for the time being. I tried to contact them many times about eta and support but they have not been helpful at all. If you buy this thing you will be on your own.
I am not working on that specific project so I don't have dates or anything like that but I can say that it seems to either be complete and may just be in the buttoning up phase. Last I saw they were validating very high speed regen so there cant be much left if anything.

As to plug & play, well, you definitely need to read my response above regarding the system design function of the VCU200 & 300. I think the Tesla board version will be a little simpler since the motor is defined but you still have the rest of the vehicle to consider and how it will relate to the VCU. Also, I would definitely say it is not plug and play since to me that means you literally plug in the supplied harnesses and while there is one for the Tesla drive, the VCU does not have a generic harness, you need to build on so no plug & play for the VCU. Also, note that the control algorithm for the LDU controller is 100% CAN based, there is no stand alone mode for the LDU. Also the throttle pedal wiring does not go to the LDU either, everything needs to come in over CAN. That puts all the torque control functions into the VCU's hands, the LDU will no longer do anything but the most basic safety de-rate functions, shifting that over watch responsibility to the VCU and adjustable by the user. I'm not 100% sure, but I believe the CAN specs for the Tesla control board will also be published at the same time as the board is released so if someone wanted to control it with a different VCU or whatever, that will be possible as well.

I did however get to drive our mule Mustang with the VCU-200 & base LDU about a month ago and it was an absolute riot. I took it home for the weekend and scared my friends with 0-90 runs and overall put about 150 miles on it.

Any updates on the sport LDU drive unit board?

Just want to correct something here, the AEM CCS solution WILL consist of an add-on CCS module. The CCS program is ongoing at AEM and no announcement or product is imminent, I just saw this and didn't want to let it hang out there when I knew it was incorrect.

Is this controller going to be a PLC to CAN bridge or will it have custom protocols between the VCU and Powerline Comm? I ask since this would be huge for the community if it didn't require the VCU and one could integrate it with their own BMS through a DBC file or something like that.
