Has anyone found a message that is sent just before the car is shut down? I am working on a DTT (Distance to Turtle) display mode and want to store some historical information to the eeProm just before the car is shut down to better estimate range when the car is powered back on.
I have to say that since starting this project I've developed a new respect for the GOM. We like to rag on how useless it is, but it is a very hard problem to solve and my own algorythm is starting to look a lot like the GOM (except it has the extra 5-6 miles the GOM hides). I'm thinking rather than measuring the actual mpkWh and using that, I will look at accelleration and braking style and use that to correlate to a number between 3 and 6 (hence the need to record historical information). Now if only I can find the canbus message that indicates what mood the driver is in...
