    CarPC for the "Race Car"

    It's time for another winter project.
    I have a 1998 Pontiac Grand Prix GTP and run HP Tuner PCM editing software on my laptop. For those interested, this software allows me to change nearly every table in my engine and transmission management PCM.

    I would like to drop the laptop and integrate this capability into a "basic" car computer. By basic I mean, I don't need it to play DVD's act as an entertainment center or talk to me on long trips to the track . I just need it to run my software to edit the PCM and scan my car.

    I am a little unsure how basic I can go, (processor speed, RAM, power supply voltage need etc?) I have been looking at some of the lower VIA EPIA mainboards (533, 800) and m1-atx power supply. I plan on putting the board somewhere under the dash or in the center console.

    My main needs that I can see are....
    Mainboard, power supply and OS with,
    Serial Port for my PCM cable
    Wireless (B is all I need)
    2.5" low GB HD ( doubt I will need even 5GB but will I find one that small?)
    Slim CD-rom maybe with R
    Wireless Keyboard and 7" touchscreen

    Any suggestions on hardware or anything else is greatly appreciated.

    I have a megasquirt, and I use my carPC for tuning.



    Usually if the PC can run software, it doesnt have to be fast.

    Id get the fastest you can get, only because after buying an EPIA m9000, I hoped for more than I got.

    Here are recommended system requirements for HP Tuner.
    Recommended

    650 MHz CPU
    128 Mb RAM
    Microsoft Windows® 2000/XP
    Serial Port* (Version 1 Serial Interface Only)
    USB Port (Version 2 USB Interface Only)

    I am leaning towards the m10000 just because the prices are so close between most of the mainboards i've been considering.

    Why don't you try and find a cheap desktop with those specs, or a cheap laptop with those specs.

    Those specs really aren't that high.

    You talk about the Epia, and of course, they will do the trick quite well, but if ALL you want to do is engine tuning, then get the cheapest you can find.

    You can get a complete Laptop with those specs for less then the Epia MB, then all you need is a 30 dollar Dc-DC laptop power supply, a screen (which you need no matter what) and a couple minutes with a soldering iron.

    Of course, desktop systems with those specs, complete with HD, CD,Sound, Video, and a DC-DC like an Opus 90 will probably be about the same price as the epia MB as well.

    And, not to knock you, but a front wheel drive race car?

    Thanks for the suggestions.

    I guess "Track Car" would fit it better since I still drive it everyday.

    There are plenty of fast FWD cars out now-a-days. The FWD platform is a fun challenge at the track and not to many people expect the "Grocery Getter" Grand Prix to click off a mid 12 sec timeslip. My goal for next year is 11.99 with race gas and slicks i'm at 12.7 now with street tires. Here is a list of our top cars, http://www.3800pro.com/lists/fwdquarter.html

    Sorry, I thought you meant "real" racing, you know the kind with both left and right turns, and accelerating and braking.

    I guess for drag strip use front wheel drive is fine.

    haha a bit hard to apex a drag strip... if this car is your daily driver (i assume you have a stereo).. maybe going a little farther out with the pc and using it as a replacement for your car stereo as well could save a few pounds, i understand how important weight is (my car would be a slug with anything short of the 250hp/250trq it has... even as 3300lbs)
