You were right on. Most of the Tesla Model S code worked straight away. I have made a pull request for my initial work that involves only the Tesla CAN bus on Can1. I have not even started looking at the Toyota CAN because most of the useful stuff is already broadcast on the Tesla bus.

I pulled the cooling system temperatures and pump speed percentages and put them in new vehicle specific metrics. I fumbled my way through copying the method of making a vehicle specific web page from the Nissan Leaf code so that I could display that information. However, I got stuck when populating those metrics into the web page. The compiler throws this error for each of my new metrics:
