    I ran across this on the Caddy Bulletin Board. It looks very cool and cheap to. www.rustbucket.rockcrawler.com

    That is amazing. Just two days ago, I was pondering how to build something along these lines. Now I see that it is possible - I am going to try it as soon as i round up some injectors, and a manifold.

    Well, I may have jumped the gun on this one. After looking at the schematics and parts list it would seem that you have to build the board yourself. While I do know quite a little bit about computers, this appears to be a little out of my league. Any electronic or computer engineers out there want to throw one together for me?

    I hijacked this for the Caddy Board.

    It will take approximately two to three weeks to have the prototype PCB
    boards made up, populated, and tested. Once this is complete, we will start
    up the one-time group buy. The original goal of U.S.$100.00 per kit plus
    shipping (professionally etched PCB with silkscreen and soldermask, all
    board components including pre-programmed micro-processor and MAP sensor,
    connectors, and case) is still on track. It looks like the lead times for
    the components and the PCB fabrication will be around 4 - 5 weeks. So, with
    no hiccups with component leadtimes, ship time for the kits should be right
    around the end of December/first to middle of January. We need at least 100
    units ordered in the group to get the price down to the $100.00 target.

    Please hold off on requests for kits until we are ready - we will post the
    details of the group purchase when it starts up.

    Also, we have posted the PC Configurator program on the WWW site, and all
    of the required embedded files, along with the P&E assembler. Note that
    there will be some changes to the PC Configurator and the embedded source
    occuring within the next few weeks:

    1) A better tuning page for the PC Configurator, to include all runtime
    parameters and allow for one-handed tuning, while keeping the other hand on
    the steering wheel.

    2) With the change of the FET driver to the On- Semi MC33151 device, the
    output drive form the processor will need to be inverted in software. I
    will make this as a #define in the beginning of the code to allow inverted
    (for the On-semi driver) or non-inverted (for the totem-pole circuit).

    3) The addition of a "Bootloader" code which will allow one to re-load the
    EFI embedded controller program via. the serial port and PC Configurator.
    Right now, one has to program the GP32 device using a dedicator programmer
    or programmer circuit. With the bootloader program burned in (using a
    regular programmer the first time) one can re-load the entire program with
    the current MegaSquirt hardware, i.e true in-circuit re-programmability.
    Any new algorithm changes, bug fixes, etc, can be easily downloaded right
    in the car via. the serial port. I should have this code finished and
    tested before the group purchase shipment, and included in the
    pre-programmed GP32 parts.

    WOW! I'm there! that's awsome! I guess it looks like you just salvage a GM throttle body then hook up that computer a few sensors and your set. Realistic figure would be $100 for the ECU kit and probably $100-200 for the rest of the parts you need if you can junk yard some of it. $300 for FI is dirt cheap!
    Sweet thing is I repair Cell phones so I have awsome electronics tools and solder gear. Heck my Soldering iron with tip is a $700 Metcal (serious high quality stuff).
    Keep us up to date. I may be game for that.

    I don't need no damn shop manual, I got a pornographic memory.

    i still dont likes it. i will stick to the g.m tbi system i have been buying them complete for less than $300.00 for every thing and you can buy all the parts to repair it at any parts store. in my area autozone stocks the new ecm for like $70.00 . what if you need to replace this homemade piece on the trail? i suppose that you would be SOL!!!!! not knocking its an ok system but GM is king daddy of F.I. and been doing so since 87. and even if ya have this computer you still have to have alot of sensors and a tbi,a fuel system. and also will have to fabricate a wiring harness. just my opinion.
