Getting ready to go forward on my install, and I was wondering if there's somewhere I can find what capabilities I have on my truck using an OBD-II connected to my serial port (I'll be using streetdeck frontend). I'm sure it varies from vehicle to vehicle; is there a list of what can be displayed on each vehicle (ie boost, egt, fuel pressure, rpm, vehicle speed, trans temp, etc)? It seems that I saw something like this before, but I can't seem to find it.
You can issue a SupportedPIDs request that will tell you what PIDs are avaialble on that vehicle. I believe it is a SVC ID 1 or 2 request and the PID request is 0 I think. It is very late here and we have been getting cars and software all day. If you need more help let me know

I'm not sure what you mean by this? I don't have a whole lot of background in this - I'm learning. Can you explain what this means?I believe it is a SVC ID 1 or 2 request and the PID request is 0 I think
There are standardized PID requests to get certain information. THere is a PID request to request what PIDs are supported for a given vehicle ECU. I am sorry in that I only know the functionality of our software. What software/hardware are you using to interact with OBD?
I don't have any hardware/software as of yet, but my plans are to run streetdeck along with whatever I need to get the diagnostic feature to work (given it can benefit me in some way). That's my main holdup at this point as to whether or not I will bother with the OBDII functionality. Can you tell me what features your software supports for an '04 GMC 2500HD Duramax? Thanks,
I have a list for the 04 Avalanche and Yukon. I am pretty sure that your truck may have a lot of the same but would be happy to work with you to figure it out. Once again I am simply trying to see if what we spent the last year and a half on has any value. Here is a small list of the things I know we can get for sure are:
all OBD, PRNDL, RPM, door locks, actuate and sense windows, door open sensors, speed, wheel rotation, etc. The Yukon has a few more things becasue there is more stuff to sense and actuate in it.
We have two different ways to integrate into StreetDeck and since it is simply an SDK I can help if you need other ways.
Are you hoping to buy a drop in package or go as far as to tinker with code?
I will be looking for a drop in package - I don't know much coding at all. My guess is that there is even more that can be done with the duramax, given the additional sensors on the engine (boost, fuel pressure, etc.). I know there are a bunch of aftermarket modules that you can plug in and get this information, not sure if this is done the same way your hardware/software does it though. Some other things that are nice are being able to calibrate speedometer for different tire sizes, among other things. My guess is that programming anything is probably beyond the scope of what this will be able to do in streetdeck, but I may be wrong.
Some of these modules offered go so far as to calculate torque and horsepower produced (I assume through transmission sensors). I'd be interested in what my vehicle is capable of and would be willing to test some stuff if need be.
I have an O3 Avalanche and I would love to get this information if you are still around?
I would greatly appreciate it.
I will be tinkering with code.
