How? modifying a maf housing=leaner conditions by fooling the ecu..

so if I give you a hyper ground kit for a tercel, does that mean it wont work on an Si?

[Dwn4nythng]

The videos I made are a reference guide, no one is putting a gun to your head to do it or not. You can cut out the maf housing, use the stock fins, use the SI tube, filter of your choice and still gain some ponies. There's not alot of people who will pay $300-$350for a homemade intake. Either their on a budget, going to college, can't afford it, etc...NOTHING is better then FREE. The choice is clearly up to you.

hate to tell ya man, but you did say "2007 SRV" in this vid at the :45 mark.

We would want the maf sensor to read it right. The maf reads it wrong, it will go lean or rich. Rich = too much gas, lean = too much air. X mentioned, he's tricking the maf into thinking there's less air. You trick the maf into thinking there's less air, your going to run rich for sure. You would want the maf to read it right so it can adjust the A/F on its own. Talk about melting pistons and such. I wouldn't buy that maf housing or do it your way. The way I slanted mines is trying to give the maf sensor a more accurate read so it can adjust on its own.

Hey all, the thread is closed because we're cleaning up all the garbage posts that were made in this thread.

Here's an idea for all of you:
Instead of saying how someone's method of creating a homemade or custom intake is junk, why not offer some advice on how it can be made better? There obviously are very informed people here on this forum. It'd be great if we can all put our heads together to make this into an awesome product that everyone can make with a reasonable budget.

If you don't feel like sharing your knowledge openly in this forum, that's okay as well.

[8thgenuser]

With Dwn4nythng's approval, I went back and cleaned up the DIY a bit.

Any posts that are blatant attacks on other members of the forum will result in infractions given out. Multiple infractions may result in you being placed on moderation and/or a ban from this website.

Any posts that are unhelpful or off topic will result in deletion and may result in an infraction.

With that warning, I'll reopen this thread for further discussion. Thanks.

Lets get 2 fact straight first.

X's modded MAF housing = Ghetto Tune and more air flow
This modded MAF housing = More air flow

And actually i think if you trick the MAF into thinking there's less air it should make the comp add less fuel. Makes sense but you never know.

can you at least do research before you post stuff like this, i never said anything about tricking a sensor or anything of that matter. even if you have your dremel on low speed it will still give you UNEVEN vanes, why not post some pics the inside of your MAF, just so you can show everyone what im talking about... i FILE MY VANES not just sand them. yet you claim up and down that i sand them down with just sand paper. its great that you did the DIY, but if it wasen't for me you wouldn't know what to even try to copy. so why don't you leave it for the people that know what they are talking about and can actually complete the task of modded there MAF themselves because
1 they have the tools and files
2 they have alot of experiance sanding and shaping plastic
3 understand and know how this modd makes everything work.

you have been a hater on my intake since day1 claiming that the injen is better, i proved you wrong with dynos, then you PM me with threatening messages and how you will create your own better intake that is nothing like mine. then you clearly are going off some prototype V2 maf housing pics that i posted up. you tried to prove in your video that the Si tube is larger but in fact its not. the opening are larger but the actual volume of air through out the tube is not. as i stated over and over again i mainly use the CRV tube because its straighter and has a stock look that has the stock location for your breather and PCV hose, ( not a vacum hose as you stated in your video) everyone will see the night and day difference over my my DIY to yours. thanks for helping people screw up there MAFs

The crv piece saved me from a ticket yesterday when I was pulled over. The cop said as long as the tube is not modified its fine.

Ok, you guys just need to stop all this offensive crap. Some people on here are friends of X and some people on here are friends of Ant and that just adding more fuel to the fire on being defensive on what's what. I agree on wanting to see a dyno along with a/f readings. I posted earlier that I'd be more than happy to throw X's current intake onto my car and take before and after dynos along with a/f readings. Hopefully we can get that done ASAP and post up some results.

Overall... X didn't come up with the idea of the MAF so I don't know why people are protecting him like he's a major company that patented the idea or something. The modification of the MAF has been long discussed in forums for cars previous ours and the same ideas and production have been presented. X was just nice enough to be the first to present his modification that made good gains in comparison to other intakes and would perform the service for a slight profit.

Ant just tried to improve it a bit as we would all do to avoid paying 300 or as said 125 for a modified MAF. Why is everyone bashing on him and saying he's just biting off of X's intake. First off its not X's intake whatsoever. To get technical he just has a custom intake period. So does Ant, period. Things started getting possesive as he began selling them. And the heatshield that Ant brought up is a very good idea. It would be even better to make a solid vent route up from the foglight hole up to the filter to help colder air pass by.

X did a good job by figuring out what needed to be done to gain more power and Ant added to it with the heatshield. Without the bashing through all of this you would have a very smooth SRI with a modified MAF along with one of the highest CFM flowing filters out there protected by a heatshield. That's it... nothing should be getting possessive unless AEM, Injen, Fujita, etc. are on here as they are actually figthing for patented names. We're just a bunch of people that want to do better with our mods plain and simple.

X... good luck and I'm looking forward to your DIY.

Ant... mad props for the free info and DIY on the heatshield.

All I'm gonna do to just let everyone know is ignore all the crap everyone's been saying since 80% of this thread is nothing but defensive statements on both ends, wait for X's DIY to see how he does his MAF.... make my own, and if I mess up I guess X will be selling another modded MAF, make the heatshield along with a vent coming up from the foglight hole and venting the filter a bit better. Look what I just did! Took all the GOOD info out of this thread and basically made what may be the best SRI setup you can have! I think that's what everyone should do and jsut stop fighting for each other...

[mad monkey]

AHHH what can't we edit?! I meant to say in the first paragraph that I was willing to throw on Ant's intake. X has planty dynos to go around already lol.

[Zeuceone]

A dyno is all that is needed to show results of ants intake. Without it there's no way to prove the performance upgrade. Its good that he made it but who knows how it performs.

modded MAF have been a comon thing, im the 1st to attemp it on a Si and the first to find out correct angles... not all maf housings on cars are the SAME.. im just trying to disprove were ANT is clearly wrong, im glad hes not testing others peoples cars with this because he has noway of motioring whats going on. heres a quick test i did to disprove on his statement about the Si tube being bigger...

i mainly use the CRV tube because its straighter and slightly bigger which helps with throttle response. going super big like ANT did with his 3 inch will eventually cause MAF overload voltage. maxing it out and burning the sensor, and actually decreasing the throttle response because the ECU parameters are not ment to stretch for that kind of instant volume. this is why most aftermarket companies take care of were there sensor mount is place. who puts a 3 inch hose on a small throttle body,

CRV tube is on the left, Si on the right







the water in the jars shows how much water each tube can hold.. the CRV tube is clearly larger.

now to the filter. i DYNO tested just about every filter on this set up... GUESS WHAT, the APEXi owns in every way. plus i like that fact that the senor never gets dirty with a apex... with all other filters you will be hurting your sensor over time... the apex is nice and small, and it takes a K&N thats almost twice the size to achieve the same CFM's if you want a cheap filter then go with the filter. it at least has a air horn on the top.

the intake stand that i supply is made outta of 304 stainless steel.. it will outlast your car. i understand hes trying to make it look like this mod is a walk in the park, if it was i would have told you so.. i am the most willing person here to help some fellow si owner out in anyway i can. DIY filming will continue tomorrow.

[Zeuceone]

X thanks for taking the time to make more demonstrations and doing even more r &d to bring to us a product that perform at its best.

[aki]

This intake war is petty, and needs to stop. This post is directed to Ant, our tireless Nor Cal meet-up guy =)

I followed X's intake from the very beginning (even getting into lil debates with him about AFR). I heard him go through his various versions, countless MAFs, multiple dynos where he kept trying different setups until getting that 13 AFR that's ideal for N/A engines.

In the end I bought the MAF (which was $100 shipped in beginning? don't remember). I haven't used it yet, but for whatever application I'm going with, it's going in.

I see your point about $300 being a lot of money. I would never pay $300. But I think you're misunderstanding what ppl are paying for. Is the MAF a free part of the Si? Yes. Can you buy your own MAF housing for $20? Yes. But that's not what ppl are paying for. People are paying for knowledge. Knowledge is a commodity, and if X wants to keep certain aspects of his design that's his prerogative. Just like you're not forcing anybody to use your DIY intake, X isn't forcing anybody to buy his.

The other thing is people are paying for is labor--more importantly, worksmanship. Judging by your DIYs (I saw them all and they're great), you have a lot steadier hands than I do. You have a dremel tool. I don't. You have an exacto. I don't (lol). So not only do I have to buy the tools, the $20 MAF, but I'd also have to do a good job cutting sanding and whatever else. It's not worth my time because screwing up is a realistic possibility--hence it's not worth dropping money for. I'd rather spend $100 or $125 on something with proven results.

I don't doubt you have gains from your DIY. I severely doubt I'd get gains from doing my own, esp since I've never even used a dremel tool in my life. Hence, the investment was worth it. I don't regret it at all, even seeing this DIY--heck, even if X gave step-by-step instructions.

Last thing, I like your silicon tube idea. Turbulence would develop in ridges, particularly in bends because the air would bounce off. I think it may even be better than CR-V tubing in X's intake. I found that section of the vacuum tubing 'n such the most helpful.

+1

But man, I think both sides, both camps need to chill out with the bashing.

[xfactorwrx]

im just trying to stand by my research, countless dyno sessions and time i spent on this. ive tried a similar idea to ANT's with a 3 inch pipe to make a CAI but throttle response and road testing showed that the car can become unstable. ITS NOT tuned for such a larger surge of air before the MAF sensor. this will in the long run ruin your sensor. sure its straighter and no rigges like the CRV but at the same time its not a big deal as your car losing throttle response and burning sensors. bigger is not always better.

But in case of Ant's setup, his 3" pipe is after the MAF--so there's no surge of air. Unless you're talking about increased static friction and a ram-air effect resulting from the piping, I'm not sure the piping can throw off the reading because it's past the MAF sensor.

Maybe 3" is too big--but no jaggies is def better than jaggies

Oh and I strongly agree with your comment about Apex'i--not only does it provide the gains, but more importantly it filters the elements very well. For that reason I'd prefer that over any other SRI option. Problem is, I'm still holding out for some Icebox setup, heheh.

You have to make sure the angle is correct and the angles have to be absolutely identical and uniform accross and in. and where the angles stop in the housing has to be a sharp transition back to flat vane. It can't be a gradual transition. If the anlges aren't exactly the same on both sides you will get turbulence in the tube and accross the MAF sensor. Your car will have flat spots in the RPM range. Oh yea, did I say the angles have to be Identical? I can't emphasize how important that is for proper performance. I have been R&Ding my own for 2 months. When I first did this my angles were ever so slightly off and I had a fllat spot between 4000 and 5000 RPM's that was horrible. I found a good way to see the angles better and my car came alive. It twists the wheel shifting into 3rd. It never even came close to that before. And make sure you don't have too steep of an angle or you won't make real good power. But if you don't have enough angle your AFR's will be too lean. So be careful. But like I said great DIY for the basic idea on how to get there. Just be sure that you really take my advice on this. I've been through all the bad stuff and learned the hard way. It took me 5 air box covers to get it truly perfect.

Oh yea, did I say I love the fact that you did this. I couldn't justify spending 300 on this either. Props dude.

i trust this guy knows what hes talking about in repect to modifying VANES....

Know whats funny, I sanded 3 places, the 2 vanes and rounded the edges, your sanding all over the place. Talk about uneven sanding. Plus, I wasn't trying to do the same thing as you. I'm trying to have the sharp points to cut through the air to get a more accurate reading. Which makes much sense since everything else on the housing is left untouched. Now your trying to fool the maf sensor into thinking there's less air going into it, this is a big problem with yours. It will run lean. YOU WANT THE MAF TO READ THE AIR RIGHT. The ecu controls the amount of air and gas going into the car. This ecu is not like the others. Not trying to copy your maf housing, making it better. You say it will screw up their cars, BUT HAVE YOU TRIED IT YET, NO.
My car runs like a champ. Oh boy, wasn't a hater since day 1 my friend. I actually backed you up. I never said Injen was good because I'm a big K&N fan. When you started hating and getting a big head on other aftermarket intakes and saying yours is the best, this is when I went on my mission to prove you wrong. You can say your intake is good, don't go bashing on K&N, Injen, AEM, Fujita, etc.... You bash on them, you bash on the people who own the intake. Your calling them stupid because they bought it. You ever see it that way, no. I have both of those tubes and the CRV is smaller. Your not correcting any mistakes, if people want to make their own using this method, let them. They can do it with stock vanes or sanded. All I know, the way I do mines, less touched places = factory specs left alone. The more places you modify (sand), the more problems you will have. The vacuum hose is hooked up to the silicone tubing and I had a valve cover breather on. If you followed it right, all people would have to do is add another custom bulkhead fitting to the silicone tube so they wouldn't have to use the breather. I chose to use the breather instead. Sorry, if I mess up cars, all my cars wouldn't have gone 250,000 miles and over (racing miles with mods). A good 75% of those 250k miles is high rev, dogging the **** out of the car and racing people. As for private messaging, remember your the first one to say something to me in pm. I wouldn't waste my time on messaging you, there's no need to. I don't hide things, if I say it, I'll tell you in the public forums. I'll tell it your face. You barked up the wrong tree when you first messaged me, X. Let that be a lesson to you if you can't handle it.

This is the reason why so many people emailed me or private messaged me saying,"Thank You" for showing them where to begin or even giving them a idea on how to improve it. If someone makes a better one then yours and mines, am I going to bash on them, NO. All I will say,"Glad I could you help with info to make a better one then mines." You have alot to learn lil man, your attitude and unprofessional.

Like I said before, everything is going as planned.
