Thanks for sharing, Brad, this is a nice contribution. You are right - there are a lot of common messages and I already see a lot of information in your document that we had not yet established for the LEAF. On the Leaf, 292:G appears to be brake pressure
or applied friction rather than brake pedal position. It goes away as regen is applied for the same brake pedal position. On the Z, it may effectively be brake pedal position but I wonder if it is really applied friction as it is on the LEAF. Also I do not think 292:D is battery voltage. It mostly hovers around 7f-80 for me too but I know the battery voltage fluctuates from 11-14. Curious, though, I see it dip twice during a short log I took while going through a car wash. I have spent many hours trying to find a passive message containing accessory battery voltage and have come up empty even knowing what the sensor is outputting via the active message. Have you tried querying the 370Z with the 79b/7bb message pairs like we do on the LEAF?
I'll keep looking to see what other gems we can gather. You probably already found it, but here
is my spreadsheet with the LEAF messages.
