    Ok computer genius!! I need you help please

    Hello all,
    My project has even exceeded my knowledge and I now call upon the automotive computer people for some help.

    This is not just computer reprogramming or stock computer modding.

    I have a Holley Commander 950 stand alone computer system on my car right now AND IT WONT START!!!

    The system originally cam from CHRFAB.com. I bought it used from a fiero guy that had a northstar in his vehicle. I have a laptop that is running the software for this setup.

    However I am at the end of my patience and trying to learn on the fly...

    I am looking for someone who has SOME knowledge more than I in aftermarket computer systems for fuel injected cars.

    email me at soccrplayrgtp@aol.com
    or AIM at soccrplayrgtp
    phone 414-628-8728 call anytime

    Thanx a ton everyone
    Travis

    Re: Ok computer genius!! I need you help please

    The first thing I would suggest would be to call CHRFab and ask them how to set it up (since they do it all the time). If they're no help, then try calling Holley, and see if they can give you some tips. Deos the engine crank? If it cranks but doesn't start, maybe it's not getting a signal from the crank or cam sensors. Or perhaps it is not firing the coil packs/plugs in the proper sequence. It could be any number fo things. It's really hard to tell without it sitting in front of me, as I can't tell exactly what's going on with it. As I said before, I would suggest contacting CHRFab first before you do anything else. They would definitely be able to help you (probably better than anyone here) as they deal with this stuff every day. Good Luck with the project. It has turned out extremely well thus far. Keep up the good work.

    I can help you....... The maps chrfab sends you are crap though. They'll get it running, but barely.

    It's probably something simple like you forgot to hook up your fuel pump.

    Re: Ok computer genius!! I need you help please

    yeah.. the four prong connector, well on the computer side I only have three to the computer (male prongs inside) four. I am missing wire connector #4 with is ModA and ModB to the Computer into the computer A2 and A3 spots. Weird. Can you check yours to make sure I'm supposed to have it (I'm going off of the LS1 wiring diagram cause I dont have/wasnt offered an electrical diagram. I have an ECU pinout and it just says A2- ModA (laptop computer) and A3- ModB (laptop computer). Alos I dont have my tach, fan, or AC request wires hooked up.. Shouldnt matter cause I just wanted to get it running first but at this point i figure I woul ask cause im stumped.

    thanx

    ANY IDEAS?

    Re: Ok computer genius!! I need you help please

    Yeah, thinking about it, I kinda remember it only having 3 pins on the laptop side... I can't check because it's in a box somewhere.. So can you get it to communicate with the software, or not??

    You're going to need it to, since it may be loaded with some funky file for a 350 or something.

    Re: Ok computer genius!! I need you help please

    okay then..... hook it back up and try using it

    Worst case scenario, you either hard wire the two together, or order a new cable from holley, right?
