I wanted to try this but our injectors are low impedance correct? How could i do this using maybe a different power source like a phone charger? or cordless drill charger with less volts or something? Any ideas? And anyone got an idea of how to setup the entire circuit?

Im thinking of a setup like this.

The voltage source doesnt matter in this case. As long as the power source is able to handle the current. Phone type wall warts may not be able to handle the .75A a High Impedance resistor require

Your second post with the picture is the best method using the battery.

The video should not have been shot indooors. . .next to an oven!

From the RC Engineering web site:

Injectors are classified into two categories.
1. High impedance/resistance (saturated) 12-16 Ohms.
2. Low impedance/resistance (peak & hold) 0.5-6 Ohms.

Saturated injectors require roughly 1-1.5 amps to open the injector. Peak & hold injectors initially needs about 4-6 amps, and once open drops to roughly 2-3 amps to keep it open.

ECU design will dictate the use of one or the other. Most late model cars will use saturated injectors.

 

Ima have to try this some time. Should be pretty easy to make the circuit.

 

I have a compact battery re-charger i can use as my power source. I will update this with pics when I get the setup done. I gotta get extra injector clips first for my injectors so I can do this.

 

Sorry for the crapy pic I did it with paint and I did it on my cell phone lol. The B stands battery the S stands for switch (momentery). I stands for injector and R stands for resistor... you will not need the resistor for high impedance injectors just for the low impedance injectors you get the idea. Note I'm not sure wat resitance resistor you would need I'm sure you could searh on hear and find out....

 

I just took mine to a place that specialized in diesel injectors. They charged me $8/ea to clean and balanced them.

I didn't know what shape they were in because they were the injectors that came off the engine I bought. Good thing I did because one was way off.

 

Yea...thats a cheap way v.s. sending them out but here in MD there arent any places I know of to walk in and get them cleaned cheap like that. Plus most people here are DIY'ers. Same goes for a oil change. You can go to a shop and pay 19$ for them to do it or go get your own oil and filter and do it your self for prolly 18$ lol.

And as far as the resistor goes i dont know what to use at all....i think a cell phone charger has a low enough power output to not kill the injectors. PLus my car batt charger has a low charge setting so that may work as well. Im going today to the junk yard to get spare injector clips to start wiring this up.

 

You dont have to have a place you can walk into... you can mail them into a shop that specializes in cleaning and testing injectors. Cost is $17 per injector with return shipping included... to KNOW they are done right. Cleaning the injectors, properly, is something a little more specialized than an oil change.

If you insist on attempting to do them yourself, all the parts can be had here:

Good luck

 

^ Thanks for the link. My reason in saying that wasnt to compare the ease of an oil change to the ease of cleaning an injector but rather the price and the ability to have been able to do it yourself. And it shows because cleaning one injector is the same as an oil change but even tho the cost is low wouldnt you ( or I guess I should speak for myself) rather do it yourself?! I figure yes with it being called a DIY project. Thanks for the link because I knew nothing of the rebuild kit. Very much needed.

 

why not just run some Techron through em?


i can definitely see the benefit of flow balancing but not buying/building a halfass setup just to squirt cleaner through em. If they are bad enough to necessitate an intenstive cleaning you should probably just replace them.

also, the injector resistance listed above is misleading. all honda injector circuits operate with about 12-14 ohms resistance, it doesnt matter where the resistance comes from (injector itself or the resistor box) this means that amperage draw will be about the same regardless of which type of injector you use. total circuit resistance dictates circuit amperage, not the ecu. ecu merely provides the ground signal, power is common source voltage.

all you would need to do is find a resistor at radio shack or a resistor box if your injectors are low impedance so that total circuit resistance is roughly equal to 12ohms. then a momentary switch to close the circuit. plumb your solvent however you feel necessary although pressure at least that of the car's fuel supply would be preferable
