(I had no idea where to post this, so mods feel free to move it)

Ok, so after reading through a few threads here and there, I read through a VAFC thread and someone said that, since the VTEC part of the VAFC doesn't work, we should just increase the fuel and our cars will respond better if running lean. I believe this has something to do with the ULEV on our cars. If I'm wrong, feel free to correct me.

Anyway, so I was thinking, to get just a little more kick in my car, this is what I want to do:

I want to take off my intake completely; it's an SRI. Then I'll reset the ECU, therefore tricking the computer into thinking there's more air coming into the car, thereby adding more fuel. Then afterwards I'll stick the filter back on and try it. This would only be temporary, as the ECU would later on learn to compensate.

So my question is: Is it worth it? And what do I do about the 02 sensor? Should I just let it hang there and let it read the ambient temperature?

Maybe this would be something to try at the track to lower the E/T by maybe 1/10 of a second.

I'm just brainstorming, so no flaming.

i think turning ur car on with no filter is bad for ur car...dirt from ur engine bay will go inside ur car...and once u put the intake back on, the ecu will rest and adjust urself..u mite have like 5min of "power"...thats jus my guess...i think im wrong however.

i did that before on my 94 Maxima



i rode without an intake box for about a month
my car stalled on me....and i have an AT
so i put it back on

LOL Dont do it, its horribly slow because the hot air from the engine OMG I have done it on my car and can terribly feel the difference in my CAI and with no intake on whatsoever.

Hmm..

To g_50b: What if I put some kind of netting at the end of the intake? Won't that prevent anything from going in, while allowing more air to go in?

To Vinh: Did you notice any gains at all? I know it was an AT..

To Elite: I'm not planning to ride around without an intake, I just want to reset the ECU, make the ECU accept that more air is going in so it'll put more fuel in, and then put the filter back on. Then I'll just ride out the ECU compensating.

Thanks for the input, though. Anyone else have any similar ideas or thoughts?

the computer will auto adjust back when you put filter back on....

the intake already sucks in a whole lot more cfm's of air than the throttle body can take therefore it would be pointless because you would still be sucking in the same amount of air.

My friend suggested to me, to remove all intake components (airbox and such) then use some cheap, large diameter piping from pepboys and attach it to the throttle body and on the other end use a pair of mom's old pantyhose to cover the end...and VOILA...ghetto SRI!!

I haven't done it yet, but I'm thinking it's possible...what do you think?

 
Rep Power: 301

After a while the pantyhose might get warn and be sucked into your intake. Heh, I'd love to see you take it back to Honda with that problem...

 
Rep Power: 314

That would be rather amusing trying to explain how pantyhose got sucked into the intake...can you say kinky! But seriously...fasten the pantyhose with a ziptie or something...?

 
Rep Power: 0

it will be like 5-10 minutes then the comp will be adjusted....so i wouldnt call that "trickin" it..... could work if you had people workin under your hood while your rollin up the stagin lanes haha

 
Rep Power: 314

Theorhetically, and I can't spell that right, it should work like an SRI correct. The ECU adjusts to that as well, so it will serve the same purpose and have the same effect.... right?

 
Rep Power: 380

acutally its been proven that having a filter of any sort (Just not mommies pantyhose) improves air flow over just open pipe.
It deals with evening out the air flow.

 
Rep Power: 314

Ok how about this...I buy some cheap piping from pepboys and a cheap APC filter...put the two together...and voila...another ghetto SRI!

Ever since I installed my header I've noticed a few VERY minor detonations. I hate that it happens. . . and so I think what I'm going to try is find out how much more fuel an RSX fuel pump will deliver over the Civic's. If there's a difference (and this would help with a later K20 swap, anyway) I'm going to look into doing that, soon.

At that point, however, I may still need to upgrade my fuel management system. So in the meantime, I'll also be researching those a bit.

you talkin small knocks or pings? nasty gas or not high enough octane maybe?

 
Rep Power: 314

Where the hell did that come from? I'm talking about GHETTO SRI's and he chimes in with RSX feul regulators...I'm not even close to needing to know that info buddy! I'll hit you up when I do.

 
Rep Power: 0

Come on now people!!! You will trick the ecu, then you will flood your motor with extra fuel for the extra air that isnt there!!!!! Plain stupidity if you ask me!!

 
Rep Power: 314

No it should work like a regular SRI, just cheaper...that's all I'm going for.

 
Rep Power: 0

The reason for this idea was because, being our cars are ULEV, I imagine that our engines are running just enough fuel to get our cars going. I wanted to "trick" the ECU into at least thinking more air was going in, therefore it would add more fuel, therefore adding maybe 1 HP. Someone once said that by making our cars run lean, we'd get more of a response out of it. This is something I'm going to try at the track or maybe someone else could try it.

And Olympicdrinker, lol, don't try that pantyhose idea. Just get a pipe and a filter. LOL, that's just too risky, I'd hate to think what could happen...

And Yukonart, check out that RSX fuel pump, and let us know if it'd be worth putting on our cars.

I've already resetted my ECU and noticed nothing different. I'll try to find out some more info on all this...

 
Rep Power: 307

Damn. . . didn't realize the world revolves around you.

I mention the RSX fuel pump because this thread seems to harken to the likes of getting MORE fuel to our intake manifold. That fact stated, I was coming up with an alternative (and maybe more effective) means of doing just that.

Since you're young, about 21, I'll go easy on you.

Just because I posted right after you does NOT mean I was addressing your post. Just because you're trying to come up with ways of making a ghetto SRI does NOT mean that's what all subsequent posts should follow. I offered an idea based on a current issue I'm having that is somewhat related to the topic at hand. And since you've got so many performance mods on your car, already. . . I'm sure you can understand that. Oh. Wait. You don't have any on there, yet. I'm sorry. . . At least I don't SEE any performance mods here.

So before you go off the hook with your gallant attempt to be helpful, try and have some insight as to what someone else is trying to suggest.

Oh, and let us know how your engine's performing once you get some "headers" (yes, plural) on there. I'd be very interested to see how many more HP you get out of that kind of exhaust setup. God knows those floor mats you added to convert your car into a Type-R have GOT to be helping a bunch.

Thanks for playing.


Pinoypryd - Actually the small detonations even occurred with 94 octane, the last time I was in Vancouver, BC! So I know it's not the fuel I'm using.

CivicRookie - I will post some information once I get around to doing the research. With the show schedule so tight around here it's unlikely I'll get much of a chance to play around with one until the beginning of September. In the meantime, I'll be looking up technical sheets on both fuel pumps.

hey Yukonart, ,weve got one gasstation here that sells 100octane unleaded here, you have to ask for it because its locked up all the time, also its 3.95 per gallon, but maybe that much octane would make a difference?

 
Rep Power: 307

Nah, really anything above 89 or 92 doesn't really help any unless you're running FI. I just wanted to note above that I KNOW it's not too low an octane of fuel generating the problem.

Again, this never happened before installing the heftier DC header. With the CAI and TCS exhaust, I already had a good deal of airflow. Only thing really holding things back now is the cat. Not going to worry about that until the swap.

Thanks, though.

hehe. . noooo . . Car might flood if it is trying to pump too much gas into there. It happened to me once. I dunno how, but my car flooded itself. I had to wait for awhile then it started again. . So I dunno. . It did that and I didn't even mess around with the intake so. . It's up to you. . Try it and let us know. . if you want to take the risk. .

I appologize. I didn't see the connection between the two comments. I am but a rookie, as you so eloquently stated above. You are quite correct about the fact that I have no performance mods on my car. Thank you for poking as much fun at that fact as you did, it reminds me of the old highschool bulley making fun of the retarded kid because corky can't run as fast. Very mature and polite, says a lot about you. I was simply making a joke about being ghetto as everyone on this site is so concerned about being "fresh and clean," such as yourself. Which brings me to my next point. Not all of us can afford to have a "show car" such as yourself. I'm in college you fuuking *****! Can you remember what it's like being a broke college student or are you too old? The floormat comment was completely uncalled for! I never protested to be fast or knowledgeable, it was a simple sarcastic suggestion. Congradulations, you are officially a bulley!

 
Rep Power: 307

The sarcasm was far from evident before your latest post, you should note that.

If there's one thing I can't stand is seeing anyone (including myself) get bitched at for tyring to lend some assistance to someone in need of information. If the information I had contributed were trite or completely without merit, I could understand, and even appreciate, your sarcasm. However, my own experiences were being told in order to shed some light on a problem related to this topic, and I'm sure at least someone has benefited from it.

I do remember what it was like being 21 and in college. I was broke, too. That was 10 years ago, and I've worked my *** off to get where I am, today. (Including surviving a messy divorce that cost me an entire house) so please don't presume to lecture me on what going without is like. Up until about 18 months I was still doing it.

And what says more? Me responding to your conniving remark, or you having made one in the first place? Who's the bully?

And since you so clearly suggested that you never hinted at being very knowledgeable, who the hell are you to assume what's helpful and what isn't, anyway? Before you go hopping on the soapbox about what warrants merit and what doesn't, I suggest you take more than a minute to consider what someone else is trying to say.

I was 21 once, too. . . . although I don't remember ever making such as *** of myself.
