fuel injector independance
Monday, September 17, 2007 1:14 PM
awhile back i read how to check to see if its high or low independance, but now i cant remember, and ive tried searching for it again and cant find it anywhere. dial-up sucks for trying to research.
i have a 99 cav z24, and im pretty sure thats the year they switched mid way thru so the injectors could be either or?
so how do you check to see if i have high or low independance? theres something to do with a rectangle shape or something you have to look for?

If they are fat injectors they are low impedance, if they are skinny, they are high impedance.

The way to check them is with an Ohm meter across the terminals, 12-16 is high.

high



not always is it fat or skinny , below pic is what is being tested in above pic





best way to know is most 99-up injectors are high (atleast for GM)

Correct me if I'm wrong but a High impedance car will run low impedance injector, but a low impedance car will not run a high impedance injector.Correct? Thanks

I believe you are correct.

No it's the other way around. You Can't run Low impedandce injectors on a High impedance ECU without a resistor pack installed. Read these http://www.hondata.com/techlowohminjectors.html http://acceleronics.com/faq.htm http://www.sdsefi.com/injectors.htm

i ran low injectors on a 99 pcm that had high

granted the 97-99 computer is the same , just the programs are different

Yeah, but if you guess wrong, you let the magic smoke out.
