Is EFI injector high or Low impedance?

I checked the FSD but did not find the impedance.

You mean our stock injectors? They're low impedance.

Thanks Brian for your reply,
I am pseudo reverse engineering the functionality of the SBEC2
I agree that the Turbo injectors are generally low impedance except for a few high versions in the very early 80's.
The V6 injectors appear to be high impedance and indeed use different circuitry at the injector driver.
I am looking at the EFI injector to better understand the driver circuitry thus my desire to determine if the EFI injector is high or low impedance.
Too bad I threw out three EFI injectors during my fall cleanup.

Which injectors, specifically, are you wanting to test?

I am looking for the impedance of the EFI injector, the one located in the TB of the non turbo units

Thanks. I thought you were going after a TBI injector, but I wasn't sure. Unfortunately, I too have thrown out or given away all of my Carb/TBI stuff. If I get to the yard before you get this done, I'll certainly pull one for you.

Thanks Brian,
I will be visiting a friend over the next few weeks with a 2.5 EFI so I may check at that point

If you can find someone with the part number for the injector there are sites that i can use to find the impedance.

I downloaded a complete list, unfortunately a lot of the Chrysler ones have incomplete information. It includes all makes. It is Stan Weiss' electronic fuel injector flow data table.

OK I will give it a go as I believe I should be able to find the part number. I checked 4554101 TBI but could not find impedance value, I will have a better look later
