should I use resistors for injectors
I'm using 1600 secondary injectors, each having 5.1 ohms impedence. wired parallel from the staged injection wire of course. I know the wolf can run injectors as low as 1.2 ohms... but would it be wise to use a resistor anyways? if so, what kind?
thanks
Mike

yeah, I already have it wired so I dont really want to go back and put the resistors in anyways...
just thought it could reduce the load on the drivers a little, but whatever, I'm sure they'll handle it
btw, thank you nyt for all the info you put out in this section, has helped me a lot!

Resistors mean lower current which inturn means longer activation time, the wolf will run 2 low impeadence injectors staged without problems. If you run injector with resistors that are not ment to be there you will have problems.

if i take a ohm meter to the injector wires found at the ecu and then to ground would that tell me what resistance inj i have? also what is considered high normal and low resistance? Chris at wolf was the one who told me to put in the resistors, i think i have the bosch injectors.

I put resistors on my low imp 1680 secondairsy. Im running the stock highimp primaries. I was under the impression i had to keep the resistance similar on all the injectors. Im not having any problems.

well i already have a resistor wired into my wires near the ecu like this >R< so i would rather just leave it alone if my secondaries are low imp, and if they are high imp then i guess i will have to take it out..... NYT is what CrackHeadMe correct about similar imp on all 4 inj?

primaries are on inj1 and inj2, secondaries on inj3. i dont see why it would matter if the impedance of the secondaries are different from the primaries as their on their own driver

...i was under the impression that rotor 1 =inj 1, rotor 2= injector 2, secondaries are on the staged channel not inj3...
i might be very wrong though....

ah yeah, theyre on staged output. i was tired =] either way, same holds true with how many are on what channel and impedance.
wolf can drive down to 1.2
that means you can run FOUR 5 ohm injectors in parallel (staged) off of one driver and be at 1.25 ohms, still above wolfs limit.
with two 5 ohm resistors, youre at 2.5 ohms, over double the listed wolf limit.

i just tested my inj and they started at 6ohm and then gradually went down to 3 ohm and stedied there, i dont know why.... week battery in my tester? well either way i took out the resistor and now i can get my inj to change my fuel at a earlier percentage, like 40%staged vs 60% when i am at idle at 14 load band with rpm at 100%....... any imput?

Why do you want your staging working at 14% load????? You should also remember injectors take a while to open usually around 1 ms just to open them now if you are running 2ms on you map you could run your staging to 50% without even opening them. The smaller the injector the faster it responds as well. This may be what is happening.

running my staging at idle was only a test to see if i could get my air fuel to change by using my sec inj..... thanks for the input on the opening times on the injectors, clears things up a lot now, and what about the resistance problem? do i have 3 ohm because it stedied there? why did it start at 6 and very slowly drop to 3 in the time span of like 5 min?

its draining your meters battery most likely, some meters(cheaper ones) become inaccurate as battery voltage drops. I use a Fuke but it is worth $700Au out of the range of most users.
