REC and WS500 CAN-based battery current stability

  I\'ve come across information here and there that suggests the WS500 can use REC provided current via CAN.  However, the WS500 documentation says \"Note: If instability is seen with Current Regulation, connect WS500 Current Shunt Sensors to battery current shunt.\" Is there anything that reduces the likelihood of instability with this approach?  If possible I would like to use the WS to monitor alternator current via a separate shunt, but I\'m hesitant given this note.  Is the problem related to the REC sample/update rate (which is pretty slow from my testing)?  If so, is there anything REC can do to increase this rate via firmware?

  You can also try wiring both your REC shunt cable and your WS500 shunt wires to your battery shunt in a WS500 battery centric configuration.

  I am testing with beta firmware and my numbers are all over the place right now, but I will when I can.

  Guys, after a good conversation with Al at Wakespeed I have deleted the last few posts.  He and I reviewed the operational integration and how it all comes together and they have pretty much done away with the term \"Alternator Centric\" in the WS500, so much of what I said no longer applies and I didnt want it posted.  I am going to be working all weekend testing and will share with you an updated reply when I have run it through a few times, and then we can pick up from there. Thanks!
