injectors

[atxcb7steve]

what the steps to upgrade the fuel injectors like witch one are the best to use for a na setup and can use the pt3 ecu for the upgrade

450cc injectors will be a good upgrade from stock because they sell like hot cake---eclipse gst injectors

now...putting those injectors on a stock ecu will pretty much run your engine rich as hell because your stock ecu is searching for 240cc injectors and doubling the rate will pretty much put more fuel in your cylinders...if you really want to do it right...you have to get a chipped ecu, so you can change the parameters of the injectors...this will make the ecu think it still has 240cc but you have 450cc instead...then you go from there with a tune

First thing is first. What's your engine setup? And what engine management system u plan on using?

now...putting those injectors on a stock ecu will pretty much blow your engine because your stock ecu is searching for 240cc injectors and doubling the rate will pretty much put more fuel in your cylinders and cause all kinds of mess...if you really want to do it right...you have to get a chipped ecu, so you can change the parameters of the injectors...this will make the ecu think it still has 240cc but you have 450cc instead...then you go from there with a tune

lol... using 450cc injectors with a stock ecu will not blow your engine. it will run extremely rich and then the cel code will come on for a rich mixture eror and you will go into limp mode.

You need a tunable ECU to run larger injectors.

Now he wants a tunable ECU...



You DO NOT NEED BIGGER INJECTORS until you have a good deal of work done to your car. Forced induction, yes. Serious NA mods (not just a camshaft and a header... I'm talking high compression, high revving, larger displacement, etc...) yes.

You're a long way off. I suggest you do some research on what it takes to build a motor. Most of your questions will be answered.

[GhostAccord]

Yeah, what he said!

[wed3k]

there's a video of a integra ls running 700cc's on a stock motor. injector duty was something like 18% lol.

car idled well but of course this is all on a tunable ecu (it has to be in order to change injector duty)

thanks for the correction...I guess we all don't know everything...I like learning something new everyday
