Am I correct in my understanding that to make this work, you have to switch over to AEM canbus protocol which eliminates the possibility of connecting additional accessories that speak native MS3 canbus?

I dont have that answer, Id be interested to hear from someone with more experience. What other sensors would you install that would need to speak ms3 native canbus?
Yes I suppose since there is only one set of CAN H and CAN L, then yeah, using it for the AEM gauge would prevent your from using the perfect tuning gauge or the arduino options.
That is my understanding as well, though I've never looked into connecting anything else up with CAN, and have no plans of doing so. All to say, I don't know all that well.

CAN devices get daisy chained together, so it is expected to only have one set of CANH and CANL pins. Unless things have changed since the last time I've looked into this stuff, Megasquirt CAN broadcasting has it's own protocol, which is what is used to communicate with CAN dashes or expansion like the TinyIOX. AEM uses a different protocol. If both were activated at the same time, there would be data conflicts. Thus if you use the AEM settings in your CANbus setup, you have to turn off CAN broadcasting.
