370Z CAN Bus Proprietary PID's

DIGItonium

Nice! I've been thinking about the same project in which I want to output to a composite video input of my head unit with the Arduino. I want to refresh the entire screen instead of printing it out in log format. The only issue I have is the resolution, so I thought about using a Raspberry Pi and write a Java app to make it look pretty on the screen with a touch friendly UI. Among other features, real-time plotting like an oscilloscope, bar charts, and the ability to view peak and hold.

All I need to do is query the data in real-time (similar to the console output) given the list of PIDs, and then parse the raw data.

This is something I'm already doing at work in the .NET world. Although my other option is to get a hold of Mono for Visual Studio so I can quickly code stuff in C#, but then it'll be an Android app.

BTW... what sort of response do you get if the PID doesn't exist?

He's just listening in on the CAN bus and printing it to a screen. You don't have to send any commands unless you want to start querying the OBD2 type information. The information he has printed is actually used by the car to function.

radensb, when you start logging we should decide on a standard format so we can exchange logs and input them into whatever programs we write.

Here's an example I did early on using excel, but my VB.net program is coming together slowly which automates the process of comparing and graphing information to figure out what they mean.

I start by backing out of my driveway and then I drove around my neighborhood a bit (reverse = -1, neutral = 0, first = 1, etc.).
