Interacting with Onboard Car Computers?

joshmccormack asks: "I've seen lots of projects where people are making great looking computers that fit into the dashboard of their cars that play MP3s, movies and even some that do some GPS and mapping stuff. I'd love to find projects where computers connect with the on board computers in most cars from the mid 90s on to show temperature and performance of various parts of the car. There are diagnostic tools that mechanics use, and that you can get to get data, but I'm particularly interested in real time, in-dash, open source options."

Do I know what I am talking about?

I think people who develop software/hardware for doing auto stuff have to pay licensing fees and junk like that. And I think that stuff is also limited to dealers for the high-end stuff. GM Goodwrench has priority over Greasemonkey Auto for the good stuff, and that priority probably come with how much $ you have to pay to GM or whoever.

A lot of the auto mechanics shops just have error code readers, with the capability to disable the error codes. That is all they need pretty much.

I also bet that most car computers dont have the output capabilities that you desire. Probably you would have to use a whole custom computer from a 3rd party. Those are probably expensive too.

Specialty shops do this now

A lot of the specifics you are looking for are probably already done by a speciality shop. For example, I love my Camaro Z28, and ls1edit.com has a $500 setup that will tell me everything about the car in real time.


I doubt though that car manufacturers are going to standardize on anything electric except the emmissions part, and that's probably the goverment forcing them to. Geez, take a look at aftermarket radios, If they could standardize on anything it could be that.


Now, if someone *would* build a custom touch screen LCD screen that fit perfectly where my radio and environmental controls are and then made it open enough I could plug a laptop into it (MP3s, Maps, etc..) then I would be one happy camper. Of course, it would have to be skinnable (for my mood) and environmental controls would have to be included in the touch screen LCD. Well hell, just include the lights, wipers, hazards, defogger, yadda yadda ya.


Hmmmm, I should get to work on that now. To the patent office! First comez za money, then comes zee power. Bwooo ha ha ha ha.

Re:Well sourceforge to the rescue

Then again, how are you supposed to google it if you don't even know what the freaking thing is called?? That's why human communities are so effective, even though almost everything can be found through google.
