injector impedance

[gravesdu_99]

Just wondering if anybody is running the 65lb injectors from mtr racing(http://www.manictechracing.com/mtr1j50fukit.html) with there stinger. And if so I could you tell me what setting you use on the stinger for the injector impedance. I don't have an ohm tester handy. Also if you could show me what you map looks like that would be great. thanks

Those are Delphi Multec Injectors.

2 ohm rating

need an ECU capable of peak hold OR resistor inline.

Just wondering if you were going by the picture. The injectors that I have are narrow body. I can't remember what I did with the part number, but I'll look. The website says that their high impedance injectors.

A quick verification with an ohmmeter maybe in order if there is any confusion.

I don't have an ohmmeter as of right now, that was the reason for the question, but the box that they came if had a part number of PFU 041-0651. They are from precision turbo, where the site says that are 12ohm. All I did was cut the old clips off and wire on the new clips. So I was wondering if these would still be 12ohm at the stinger, or does the impedance change at all. I know this is a stupid question, but I have read some stuff about running the injectors in paralle or series and I'm not sure if people are wiring them in order to run them paralle and series or if the wiring is already set up this way from the factory.

7M with factory wiring?

You post a picture and then you tell us not to go by the picture?

lol

Anyway perhaps next time instead of posting a picture... a part number will work.

Those are 12 ohm injectors.

Running them in parallel will make them seem like a 6 ohm resistance. Serial = 24 ohm resistance.

These are in a 1jz motor with a wiring harness made by Drtweak.

Ok seeing as this has been a guessing game.


We need you configuration. Motor configuration, ECU any mods basically.

-tial 38mm wastgate
-tial bov
-Mitsimoto 3" intercooler

-Powerpurple HKS timing gears
-HKS spark plugs (imported from japan, aka came with motor)
-Aluminum spark plug clover, only a handfull made

the wiring harness was made to run a stock 1jz. All I did was cut off the injector clips at the end and wire on the new clips. I hope this puts an end to the guessing game. I notice as question came in how I left out important information. Sorry about that and thanks for the help.
