extra injectors?

Re: extra injectors?
Well...You could rig a separate injector to the charge pipe and have it turned on with a pressure switch. Real crude, but I have heard it sometimes works.
check this out, it may work.

Re: extra injectors?
All right here its the deal..
I done this a couple of times, first you have to know the injectors impedance in ohms. the lowest you can go with out fraying your ecu is 6 ohms... the ohms will vary depending if you wire in series or parallel.
If your car has a resistor box you want to wire a low impedance injector in parallel if you don't then you are a hi impedance and can wire either or and it will work, as long as in wired parallel
piggy back the signal from the injector negative wire (put the ignition in on position and the one with out power its your guy) and wire parallel to you new injector with a pressure switch to activate it. (the switch will bring the positive)
the rule its do not go under 6 ohms. so you have to do some math with your new injectors so you don trash the ecu
When injectors are wired in parallel, the total impedance is less than either of the
injectors alone.
If two injectors of equal impedance are wired together in parallel, the total impedance is equal to half the
impedance of either injector. If each injector has an impedance of 3.6 Ohms, the total impedance for two
injectors in parallel is 1.8 Ohms.
If three injectors of equal impedance are wired together in parallel, the total impedance is equal to one third
the impedance of any of the injectors. If each injector has an impedance of 3.6 Ohms, the total impedance
for three injectors in parallel is 1.2 Ohms (this will allow you to use a pressure switch to turn them on and off)
Series Injectors – When injectors are wired in series, the total impedance is equal to the impedance of all the
injectors on that output added together.
For example: If there are 2 injectors wired in series, and each injector has an impedance of 3.6 Ohms, the
total impedance of the two injectors is 7.2 Ohms. (all injectors stay on all the time since there its not a way to cut power to one with out knocking the other)
something its telling me that i'm missing something but i'm sure one of you guys will come up with something and i will remember. i got a low budget rust bucket 1990 civic running like this. make sure you get a quality switch i had one that popped.
