    Carpc as a dashboard replacement?

    Here is my situation. I've had my transmission fail out twice on me and finally got it put back in the other day. I'm still testing it out and hoping it works this time. When my transmission first went out I noticed my speedo not working once I hit 55-60 mph right before hand. After installing the first rebuild, I noticed my tach did not seem to be quite right either. It'd cost me a bit to fix the two, or even just the speedometer so it was suggested I just get a $50 gps unit with speed. First thought is I hate the Tomtom that I've used before, Two I can't find any for $50 anymore. Then I got thinking about it and wondering if there was a way for me to integrate my gauge cluster, gps, ipod, and bluetooth for my phone all together into a touchscreen. I ended back up with a carputer.

    So I'm wanting to know if it's possible, if there is software (preferably freeware or donation) to get the dashboard info (tach, speedo, ect) into the pc and onto the screen and be accurate for a 1997 Chevy 1500 Cheyenne.

    Second what would be minimum specs for the computer to reasonably run all of that, prefering a linux distro for less overhead on price and resources. Trying to figure out how much it would cost me to get setup. I also have very little space as it is a single cab pickup.

    Thanks

    Hi, to get dashboard info on the computer you'll need to use OBDII. I don't know much about it, but I don't know of any free OBD software. And it will probably be even harder to find suitable software for Linux.

    Some one will probably mention that you should have ordinary gauges as a backup if the computer stops working, maybe behind the virtual dashboard screen. They might even be legally required. Again, I know next to nothing about this, so you should wait until someone more expert comes along.

    check this out.
    that's just software, you'll need this to interface between the pc and your truck.
    for a pc you could an existing laptop you have, or buy something like this along with a small touch screen such as this.

    dash command will only work with xp, but both are pretty light on resources, i couldn't imagine it requiring more than our typical music and movies carputer requirements.

    hope that helps.

    the good news is that you have a obd2 diagnostic port on your truck, so you should be able to use the elmscan module to get any info you want.

    the bad news is that there is not yet a proven reliable solution to software/component computer controlled gauge replacements(there are computerized, reliable, race type engine management solutions though, but these don't use user installed software...)--possibly getting into legal/driveability issues with the car...there are a couple of threads on this in the engine manegement section, and the general consesus is not to actually replace the gauges, but to add a secondary display-- because driving without gauges is like asking for trouble...

    Chances are your speed sensor has failed, which is about a 40 dollar part and not that hard to replace yourself. I don't know your level of mechanical aptitude, nor have I ever done a VSS on a 97 Chevy 1500, but it can't be any worse than most cars.

    Does the tach not work at all, or does it read completely wrong? Fixing these issues will be cheaper than building a PC to replace them, and then you might have the legal issue of someday trying to sell a vehicle without a functioning speedo, and therefore odometer.

    Plus, if your sensors have failed, the data coming out of the OBD is going to be bad anyway.
