370Z CAN Bus Proprietary PID's

ZeN

Nice find. I'll see if i can get torque + elm 327 to go into diagnostic mode like you did by creating a custom pid and put the initialization string on diagnostic command. If i can at least get the standard pid then it will be good because my car is jdm and it is not obd2 compliance. Only manage to get 11 pid which is from Nissan Adv plugin. Dont know what they did different.

i have the full source to uprev so i could check to see how they're doing it, wouldn't have to reverse the PID data then

That would be great. Any chance you can dig through the source and then send me portions of the code that interpret PIDs?

In fact, this screenshot from their program is exactly what I'm looking for. Those values listed on the right side are exactly the ones from the service manual that are supposed to be accessible via the Consult tool. The ones I've decoded so far match the list.

If you can focus on that from the UpRev source that would be perfect.

How's this project coming along? I've been pretty busy with other projects, and I have not had a chance to get around to working on anything related to this one.

However, I recently wrote code to produce my own circular progress bar widget, and it can scale down to 16x16 pixels. I'm taking this idea a step further by creating meters similar to the GT-R MFD. The control drawing is ratio-based so the it will be scalable. It is also user configurable as well (colors, dial thickness, etc.).

I envision the ability to create a base program that can read in an XML file, which will determine the layout of the controls. The grid size is nearly unlimited, and it will be limited by the screen size and resolution. We'll see how it goes.

I've only spent about an hour on it, so here is a test bed for the meter user control.

This is pretty sweet! I did something similar using python and a PI and displaying the gauges in my head unit, but didn't go to far with it [https://github.com/lcintron/PyO-X]. You guys have much more robust applications, we should create a robust Windows 8 app for display this info, I think we have the talent here (pretty obvious). I am more comfortable in .NET that I am with python so this should be fairly trivial. What do you guys think?

I can code to process and display data and manipulate HTML pages on the fly by invoking JavaScript, but I haven't done much graphics coding. Currently in the planning stages to build a development workstation at home.

We can easily create the javascript framework to interface with the obd module (if not available already) and integrate it to an app built using html+js. There are plenty of libraries out there for making and customizing gauges and other controls (I happen to own licenses for a few of them) that we could use to make a pretty clean, tab-friendly, user interface. On the other hand, I am not sure about the scalability options going that route, I've only developed win8 apps using C#.

Interesting.. Keep me posted. I have a little experience with microchip and their can bus.

The last language I was proficient at was HyperTalk and I no longer have a Z so I can't do any testing (other than general GUI stuff) ... but I like to see that somebody is taking on this project and would like to help if I can. I have an OBD/CAN wiki set up (see link in sig) that y'all can use. If you're interested, PM me and I'll set you up with some extra privileges.

Has anyone tried referencing the uprev DLLs and seeing if you could pull the pids from the uprev files?

You f*$%ing nailed it! The <Address> tag lines up exactly with the addresses I found for the proprietary PIDs. So the first one is 4353 (in decimal), which in hex is 1101. That's the first one on my spreadsheet and the rest seems to match as well. This has all of the formulas and descriptions as well so it should be what I was looking for. Thanks for posting!

I wish i had seen this thread earlier but I've taken a bit of a break on modding my Z and couldn't bare to be on the forums. I'm sure I have a lot more useful info to give you.
