Wow, I'm surprised that mux is selling those! That definitely provides some hope for DIY retrofits of newer packs in older LEAFs!!

As a software engineer and leaf owner, I am really interested in seeing how you are going to write a functional CAN bridge between your 24kwh car and the 30kwh battery.
In your case, reverse engineering the 24kwh protocol seems doable, since you can observe your current battery communicating with your car in all kinds of situations.
However, I wonder how difficult it will be to understand what the 30kwh battery outputs and expects as you are missing a piece of the puzzle, the car with which it communicates.
I hope CAN messages are not too different, please keep us informed of all the gory details :)

He doesn't need to hack the CanBUS, because he already purchased a "Man-in-the-middle" CAN board from Muxsan:
