the impedance of our injectors is 10-13ohms right?

so; if our injection system is saturated and not peak and hold:
could it be posible to do a mod usually done on hondas to put dsm injectos.. meaning puting a "resistor" or a resistor "box" so the injectors work properly...?
theorically can this be done on our cars..?
heres the thing:

i allready have a set of injectors installed on mine
but this if for another proyect and i have them lying arround my home, there 1g dsm wich are low impedance... the infamous 450 blue tops and am weary to just cut the **** out of a brand new harness... any suggestions?

hope this is not too complicated... lol

 

i honestly don't have a clue, sorry. but on a side note fftopic: did you talk to the shop yet about the ecu?

 

no, sorry... i dont know but they are just not answering the phone... but im on it...


to get there in person is a day's trip since they are on the other side of the island

 

10.5-13.5 ohm, yes. I don't see why a resistor pack wouldn't work in this case.

 

so, what resistor could i use there... i mean like the "size" like a 11ohm resistor a 10 or a 13?

 

btw thx Myszkewicz!

 

measure resistance of the new injector... then add a resister in line to the source wire that will increase the resistance to what is needed. Most use a 10ohm resister standard.

I've done this on other cars before and never had any issues at all.

 

thx we will see what we can do on this... thx

 

A lot of the cheap Mirage guys do this.... get one of those 99 cent resistors from Radio Shack and wire them inline with the injectors or you can get the infamous "Honda black box" which is just a resistor box that does the same thing.

 

yes you can use peak and hold injectors, ijuts bought a set of RC injectors (550cc) for my turbo setup, and yes you can use a inline resistor to regulate the flow of cuurent, you can also use the realay board from a VW injection system,they use low ohm ijectors in they'er vehicle, but unless you have a new ECU then u wil have use a resistor to regulate it, and as far the factory wiring being cut, if you use the new harness with shrink tubing, should be no problem. I wount have that problem i'm changing my ECU to a Megasquirt system,. it has a "Flyback" board built in,so no problem of resistance, it regulates it's own voltage as needed.

Hoped this helped your question. if you need more help let me know!

 

thx to all.. i talked to the guy and told him about the posibility of cutting the harnes and he looked at me like.. "no fking way.." that was hilarious...
but thx again for answering...

 

just found this, thought I would bump it in light of all the new turbo discussions. hope I don't get another warning

 

Sorry, I'm noob. But what exactly does changing resistance do?? Is this so you can get more fuel out of your injectors by applying more electricity?

 

Resistence dictates when and how an injector fires. Low impedence injectors don't take a lot of voltage to fire and are typically setup as "peak and hold." That means that the ECU sends a burst of voltage (around 4v) to the injector to turn it on, then another burst to turn it off. A high impedence injector, like what we have, takes a larger amount of voltage to fire, and works via "saturation." that means that, once the injector recevies a signal at 10+ volts, it sprays fuel until that voltage drops.

 

In turn with lower voltage, you get better control of the injector? i.e. faster response times?
