It's finally working!
 

Hey guys,

I'm an UI engineer by trade, and gear-head by night, and decided a while back that I could mix things up a bit.
I saw the "multifunction display" in the new GT-R, and thought it looked pretty cool, and that I'd like to have something like that for my T/A.
Well, after a moderate amount of hacking, this is what I've come up with. It's still a very early and rough version of it, but it actually works.

The plans forward is to add more screens to monitor different values. Add DTC diagnostics, and maybe a virtual quarter-mile.
I'll also look into adding media playback in it, so that it eventually can replace the radio.

Whaddy'a think?

nice i like it

great idea! how did u get it to correspond with ur car? its connected by cable?

Yep, it's connected to the OBD-2 port, and gets its data from there.

is the program like some famous ls1 camaro software that i dont know about? i think it would be nice if i can connect my computer to my obd 2 port and get some info from my car

:lol: it sounded like a "ping" from a submarine at one point...

Famous? No, not yet.. :)

I wrote it all myself. I'm a programmer by trade, so it's what I do. :)

There's a ton of programs out there for hooking up your PC to your car.
I use the hardware from http://www.obdpros.com/, and they include a bunch of (ugly, but working) software with their interfaces.

Say wahh? Can't hear that here. Very little submarining goes on in my car under normal circumstances.

TTT for the day-crowd.

What gauges/functionality would you guys want to see in something like this ?

A/F ratio, oil pressure, volts, maybe gas tank level, trouble code readouts, clickable UI (touchscreen support??) those are a few off the top of my head. Maybe options to link to other programs (i.e. GPS support)? Save the carputer guys some money... :)

EDIT: P.S. This is freakin' awesome. I can't tell you how long I've wanted a car with something like this. Oh, got another idea - 0-xMPH times (unless it's not too accurate)

Great job.

1/4 mile passes would be bad ass too! :D i don't know if you would do that tho lol

Here's an update for you guys.

I added two new screens.
Screen two:
* Engine Coolant temp
* Torque converter slip
* Engine oil pressure (not working)
* Engine load (in %)
* Transmission oil temp (uncalibrated)
* Transmission oil pressure (also uncalibrated)

Screen 3:
* DTCs
* Battery voltage

Future plans:
In the immediate future I'll add graphing, so you could get a graph over your RPMs (for example) over a period of time.
I'm also thinking of how to implement an MPG meter

I could rather easily add the 0->xxxMPH functionality, and probably a virtual 1/4 mile as well with a RWHP estimation. It won't be perfect, but I think I could get it within 5% accuracy or so..

I'll probably end up integrating some form of MP3 playing as well.

Sick! :)

That could go hand-in-hand with this: http://www.ohgizmo.com/2008/10/13/mi...eeds-only-usb/ if you don't have a monitor on your headunit.. Touchscreen would be pimp though..

F'in awesome!

Nice. What are you writing it in? I have a carpc and use the roadrunner frontend, which is very popular. It might be better if you could integrate it into that or something similar since a lot of work has already been done on carpc applications.

I can't view photobucket at work, but it sounds awesome. I'll check it out when I get home.

Edit: It looks really good. Well done.

damn that is sick. i can put a computer together in 20 minutes, but programing... i dont know that stuff at all. :lol: that is some A+ work right there nice job!

Thanks guys,

I'll probably end up going the CarPC route, but not in the regular sense.
I'm prototyping my own CarPC, which this will become a part of.
What's already in the plans and semi-working is iPod integration (blows any headunit ipod integration clear out of the water), as well as XM-Radio.
Once I've got that working in the lab, it'll all be put into a PC, and mounted in the car.

I'll keep you posted
