    Default Injector question

    Well its a somewhat straight forward question, either you know the answer or you dont.
    The question itself is hard to explain so here goes.

    Ok first of all... I've done very little research on this, just brainstorming a ghetto-rigging I might do.
    Ok so injectors, they dont have polarities... The prongs inside doesnt matter which one recieves the voltage and which one grounds, same end effect. The voltage is taken from a fused connection to the battery (+12V). Right...
    The part that plug into the computer is the ground...This part gets a little grey for me.
    So the computer pulsates the ground, completing the curcuit, making the injector operate right...

    Ok now say I wanted to add another injector randomly (starion = 2 injector setup)
    Hypothetically, say i welded a spot in a hardpipe for the injector to be... etc... and wanted this to operate without megasquirt, standalone, etc.

    If i connected the +12V to one prong of the new injector and spliced the ground to the ground of the other injector. Would these two injectors operate exactly the same? Or would these injectors both not operate.
    Hypothetically this seems like it'd work.

    The only thing that I can think of that would make it not work would be the amount of ground. -5.5V (for example)
    Perhaps the grounding mechanism of the computer is too complex and any higher load would cause failure? Anyways anyone know anything about this situation? Its not something that i can just try and check, simply because its involving fuel.

    Thanks

    Oh yeah if ur not gonna post anything constructive dont post... i know its ghetto rigging but shit fuck you LOLOL

    hmmm, interesting. if those injected are gonna be wiring in parallel then its gonna lower the resistance and possily blow the computer. the injectors should be wired switch to ground by the computer. right now im too tired to try to figure this out but it kinda seems kinda iffy to me. id talk to someone whos done this or knows a lot more about someting like this than me anyway so yeah lol good luck

    you would need to make sure there was some sort of relay system or a way to keep the resistance the way that the computer injector drivers needs. otherwise you'll fry the injector driver of the ecu.

    but by doing that, wouldn't that defeat the purpose? Having two weak injectors as opposed to 1 strong injector.

    dumbass it wont werk ur gonna lose voltage or amp or wat ever u wanna call it....the longer the computer send current to the injectors the longer it stays open which = more gas


    unless u can get 2 injectors that have 1/2 the resistanceEach of the one original injector
