Re: I made a transparent CAN bus bridge with logging, requesting input

For that you'd need the 4-CAN board (or, well, at least 3 CAN buses). One needs to talk transparently with the VCM and the other would need to be read and its capacity added to the other. It's a bit involved but could certainly be done. I'll see if I can put this kind of functionality in the release firmware.

@mux Could you mod your transparent CAN bus bridge to intercept the CAN bus signals for battery charging, with the intent to spoof the stock BMS into thinking that the car is fully charged, when in fact it's at 80% SOC?

There seem to be so many post 2013 owners who want the 80% charging feature, so if you could create a reasonably priced device that would do that one thing, I'm sure you would have no shortage of customers.

Ooooooh... I understand this now. They REMOVED the 80% feature? That's stupid. I had somebody else contact me about this and I didn't understand what he meant.

Yeah, that's pretty easy to do. I'll put it on my features list.

Yeah, they really only had it on the 2013 model year. I'm guessing there are lots of owners who would pay up to $150 US, just to get this feature alone...
