Okay. Im confused on this whole injector thing.

You can search for a post by Kevin landers, he gives alot of info on how to ID them. But the easiest way is to just OHM them out .. if they come out 2-3 at the injectors they are low ... if they come out 11-14 ish they are high, if they come out niether of those they are bad

Thanks J-Rat I got the resistor pack in the mail today.

Okay this thing has 5 wires, my guess is; one for each injector and the middle\fifth wire is a ground?? does this sound correct? Can anyone please share some insight on where to mount this? and where & how to hook it up? Its the stock injector pack for a low imp injector RX7.

Thanks alot

No, Ted was right. Your equation is wrong. Resistance in parallel is the inverse of the sum of the inverses, or:

1/Rt = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn
If you have two 6 ohm resistors and a 3 ohm in parallel, the total resistance is 5 ohms.
Nope. Using the above equation:

1/Rt = 1/6 + 1/6 + 1/3 = 0.667, so Rt = 1.5

Actually, you don't need that info for injector resistors, coz you're only wiring then in series, which is nice and simple. 3ohm injector + 10ohm resistor = a happy ECU seeing 13ohm. But a little more knowledge is always a good thing.

WHAT?!?!

Crap...you are right...Thats why when you put 2 eight ohm loads in parallel, you see 4 ohms of resistance at the source. Three 8 ohms yields 2 (.6??) ohms of resistance. What was I thinking?...
