Ok, so I am needing some bigger injectors anyway (as soon as I figure out why my throttle is still sticking after almost a damn year) and there's that great deal on RC 550s...

I have the VAFC and I'm going to be using the "trick" with no FMU and no check valve. Will the VAFC idle these things or would I also need to lower the base fuel pressure?

 

man... i wouldnt even try it. just go with the Hondata. why not? im sure you can idle with the 550s... you just gotta play with the AFC to find a good setting. use some of the money you get from selling the fmu, fuel pump, missing link and slap on another $300 and you got yourself a Hondata.

 

It probably wont work without lowering the pressure. The vafc only goes down to -50%, and with 450s your already @ -40%. It might work, but you will have NO window for adjustment. Your gonna be at the edge. Then again, it probably wont take too much of a drop in pressure to correct...
If you already have the Vafc, then i say just buy the injectors and try it. If it doesnt work out you can always go back to your old setup and then look into a hondata/etc.

 

With -45% correction at idle, my 440's are still a bit rich.. I can't imagine what 550's would be like

 

Yeah but I'm OBD2 so I'm looking at a lot more than $500 to go Hondata. Believe me, I woudl do it.... but I'm also considering a B18B swap within the next year.

 

Then why the injectors?? I mean you already have a set of 450's right? You don't stand to gain anything by going with 550's on a D16 (unless you had plans to build to it hell, which you don't).

 

Keep the idle set to at least 1000 rpm.
Run about 25-30 ppsi fuel pressure.
Drop the VAFC to -49%.

It will run idle nasty, but it will idle.

Good luck, and I mean that, Good Luck.

No, I have 310s. The 550s are cheaper than the 450s. Also, I plan to get 300 WHP whether I build this D16 or a B18, so I need larger than 450. I also don't want to get 10 year old DSM injectors. They might be cheap and they might work good, but I want my stuff to be top notch.

 

Get some Used DSM 450cc injectors and a Resister Pack out of a 89-91 crx or integra. Cost you about $75

 

That's what I woulda said, but his response:

doesn't leave room for that. In any event, you ain't gonna like life with 550's trust me.. I give you a week before you take them off

 

if you want your stuff to be top notch then you should save up the $ for a standalone. running a standalone with DSM injectors is more "top notch" than running 550cc injectors with some alphabet soup piggy-back setup.

oh and by the way, RC injectors aren't exactly "top notch" either, but I personally swear by them

Ok, that was kind of smart *** and I would have punched you in the mouth if you said some **** like that to me in person, but ok.

A. No ****, of course I want a stand alone like everybody else. I don't have the money right now. I don't want my car plans to be on hold for another who knows how many months until I can afford a stand alone. Thanks for the insults on the "alphabet soup" thing though. That was very informative and helped to answer my question.

B. Running 10 year old DSM injectors is not my idea of top notch, whether they are in a Honda with aftermarket engine control or a Ferrari.

C. RC Injectors are NEW (because I will buy them new) and work very well. Unless you know somebody that has had problems with them? Exactly ... that's my idea of top notch.

Now, I hate to be a ***** to anybody on this board, but damn your post did not help anybody one bit. All it did was **** me off. After I punch you in the mouth, we can be friends again.

 

Ok #1, turn your sensitivity level down a couple notches. What he said was alot more helpful than your taking it for. I don't know if your having such a titty attack because it's not what you wanted to hear or what, but it's true. You said you wanted a "top-notch" setup, then why are you relegating yourself to using piggybacks instead of a standalone? That's YOUR contradiction, he just happen to catch it.

In any event, I agree with him, DSM injectors are good quality. Get a set that are in good shape and have them cleaned by RC and you'll be in good shape. How often do you hear of injector failures (assuming the injectors aren't over worked i.e. 100% duty cycle!), it's a rareity at best. I'd MUCH rather spend $50 on DSM 450's and a $30 resistor pack so I can save some $$ for Hondata, than spend $400+ on a set of RC 550's + $30 on a resistor pack (unless you custom order saturated which is extra $$) and $250 for an AFC which doesn't offer you the world of tunability a half decent standalone does. Your car, your call..

 

#1, he was not helpful, so **** off. Don't tell me to turn my sensitivity level down or talk down to me, that just pisses me off more. Smart ***! Is the AFC a piece of crap? Don't YOU use one yourself? Huh... maybe I should have said "I like to buy top notch components but I like having a crappy piggy back overall setup". Tell me the AFC is a useless piece of junk that doesn't do anybody any good..

#2, sure, if I could find a set RC had cleaned, fine. I have not seen any for $50 or whatever. I can't remember what RC charges to do it, but it's enough to motivate me to buy new injectors.

Damn, what's up with you guys today. When you say something, you have to know if it's insulting or irritating, so why would you expect a "oh nice, thank you"?

I asked a question. I did not ask for "that's not top notch afc sucks do it this way that's totally different from what you asked about" . Jesus, I gotta go now before I lose it.

BTW - I have a resistor pack already and 550 RC's can be had new for $269

You know what ... forget it. I don't want to fight with you guys no matter how irritated I get. This is the only board I like so why **** it up, right?

Sorry for having a TITTY ATTACK.

 

Dude you have got some serious issues or something.. I think you need to go chill and comeback later when you're cool and reread all the posts so you can see nobody is talking down to anybody, so I don't know why your telling me to **** off because all I've done is try to help you..

$50 is the general going rate for 450 DSM units,and I belive it's about $100 to clean them via RC. $150 for a set of ready to go 450cc injectors, or $400+ for RC 550's, your call.

Your the one with the tampon up your *** because you don't like the fact that there is a better, more sensible way of doing things. If your that stuck on doing it the way you want to, knock yourself out.. stupid me for trying to help. Go get those nice shiny new 550's and idle those suckers on that VAFC

Yes you asked, and how many people in here already told you about the 550sand the AFC.. they DON'T MIX. Your obviously one who needs to learn the Darwin way, so go knock yourself out. Maybe after a couple hours of beating yourself with an iron wrench wondering why your car either won't start or idles like a truck and why your plugs are black as night after 5 mins, you'll come to the reaization "Ya know, I think 550cc's with an AFC on a D16 just might be too much!".. good luck doc!

EDIT: Don't forget, Friday is just a few hours away.. maybe a few cold ones will loosen you up

we've tried the 550's and it doesn't work too well. also, after idle, getting on the throttle too hard just causes you to bog. i mean, it already can do that with 440's, but with the 550's, drivability(like going from 30% throttle to 100% throttle on the fly will cause flooding with the afc's. i got 360 to the wheels with 440's, so 300 won't be difficult. stay with 440's. just my opinion/experience.

 

im running 550cc rx7 injectors with full standalone Link computer
idles @ 1250rpm
eheheihhie

 

As it is, I get a ton of that with the 440's, well I did before the AFC change but none the less, can you imagine what it'd be like on 550's!

I'm hoping dropping to 35psi idle pressure will help some of my funny idling though, get's annoying

 

you're welcome

i agree with VTC_CiViC, you need to calm the **** down.
i guess what i really meant was that your reason for not wanting DSM injectors is not a very good reason. Not wanting to use DSM injectors becuase they're not top notch, but yet at the same time going with a piggyback setup is hypocritical.

solution: use DSM injectors! There's nothing wrong with them! If you don't trust the injectors you buy, you can send them to RC and they will clean them and flow-test them for you for a small fee ($50-100 i believe).


-Xerxes

 

Will 550 injectors will be good on a b18c ? or d16 or b18 with only afc is not a good mix ?

 

OK OK damnit I'm going to get the DSM injectors. It will be cheaper in the "right now" time frame and if I need the 550's I will get them later.

I should have been more clear when I made the original post - YOU CAN GET NEW RC 550 PEAK AND HOLD FOR $269 THRU THE LINK IN LSIVIC's SIG

I figured that's the deal of a lifetime, so I thought I would jump on it. Too much hassle though, so I will just save even more money and run the old DSM injectors for now.

Jinx - thanx for the good scoop!

PS - I already apologized so don't try to get me to say it again

Also, any good shops in the Tampa area? If all goes well I should be moving there in a couple of months!
