- Honda Injector Impedance: Don't burn up your ECU!
By Brian Gillespie
Honda injector impedance isn't cool. It isn't fun or sexy, but it's important if you want your car to actually run and survive. Typically Honda injectors are either low impedance or high impedance. But, how do you know what your engine uses or what you injectors do you have? Brian breaks it down and shows you.

I am the world's biggest non knowledgeable person. I rescued an 88 civic hatch that sat in my buddies garage for almost 20 years. In 2001 he had it b swapped. I got 1000cc injectors a turbo, p28 with hondata. I am completely lost. I have the service manual and helms book. Ughgggg
Where are you located? I might be able to help sounds like fun
Glad I found you. Subbed
Hey I just recently subscribed to your channel thank you for all the knowledge and for helping all the amateurs like myself . So i just have one question referring to this video. If the fuel injectors are low ping like you say can that cause you to get the ecu code 43 ?? I’m building a b swap ef sedan in California so I’m just trying to get all codes cleared so I can bar it and drive it legally , any suggestions or information will be greatly appreciated
Awesome
Just subbed
Any good alternative to OEM RDX injectors? They’re kinda getting up there in price unless someone knows where I can get them for less than 400$
Can I use b16a injectors on my SOHC engine and not tuning it?
hello
I read that if you use high impedance injectors, you have to connect all the wires of the resistor box together
is it true or not ?
what do you think about this ?
So I could run low impedance injectors on an obd1 setup as long as I keep my resistor in my b swapped ef?
My car is a low impedance set up i just got some dsm black top 450cc injectors they came out to be 4.6 ohms are these considered low impedance ?
Good stuff guys 👍👍
Glad you enjoyed it. Thanks for watching! With swap ecus becoming more scarce, it's a good thing to not burn them out.
@@VTECAcademy exactly. I'm trying to get into this stuff on a deeper level. And you guys are heading the spear on this type of information. I wouldn't know half of what I do if it wasn't for yall. Thanks for the hard work. 💪🏼💪🏼
To my understanding a low impedance is a peak and hold injector and a high impedance is a saturation injector. Hopefully someone can confirm this or tell me I am wrong :-) great video!
How do I tell if my computer is for low or high impedance?
@@4OhmAudio there is a little metallic box about 4 inches long by about 2.5 inches tall that sits under the hood of Hondas that have low impedance injectors…like for example my 93 accord has low impedance injectors which it has that little box next to it. I would post a pic but UA-cam doesn’t allow stuff like that
I'm using the factory K24A2 injectors on my 1989 CRX with Hondata. That should be okay.....?
yeah I have k24a2 tsx injectors in my d16zc sohc v tech coap ex never gave me any issues gave me more power and I nitrous kit too in it 75shot dry no issues works fine
Would this be needed in an 88 crx b18v with p28 and rye wire harness?and also, who do you use for dyno..ecu tuning ?
Thanks brian.
Thanks for info.
my car OEM injectors is 15.9ohm .can I use 12 ohm injectors instead?
Yes you can
Can you do a tech thursday on worthwhile Vtec pressure sensor replacements? OEM is about $100, I got one on amazon for under $15, it worked for a month... Running Hondata flashpro and have the sensor turned off at the moment so car doesn't fall on its face at 3,600rpm...
Is OEM the only option that actually works? Got 162k before it died. I don't want to keep running with sensor disabled but I also don't want to drop $100 if I don't have to.
Honda 07 GD3 FIT - (P/N crosses for K series engine as well)
Do you mean 37250-PRB-A01?
@@VTECAcademy Also once the OEM and aftermarket sensor died they will pop the check engine and fall on its face basically every time the engine goes into Vtec = leads me to the harness pigtail loss of connection not causing the issue.
With sensor disabled engine runs exactly as it should, I just don't like the idea of sensor off long term but maybe it is non-issue?
What size injectors would you recommend for a k20/k24 all motor build?
500cc they good for 3-350hp
Does k-series need high impedance injectors ?
Yes, so you would bypass the resistor box.
