MAF problems?

Alright so I'm pretty set on putting an aftermarket intake in which is either gonna be the injen CAI thanks to rolojo81 and his nice find :) or the weapon r SRI. Now all I want to know before i go ahead and buy is what are the details on the MAF problems associated with installing the aftermarket intakes on proteges? Thanks in advance.

This is NOT the place for politics! I'm a political junky with plenty of opinions on all kinds of candidates, office holders and issues. I also think people need to be more politically involved. HOWEVER, this forum is about Mazdas, NOT politics. I think we should keep it that way.

Where was there discussion of politics? Haha Ecotec is the enigne in Cavy's? And I didn't turn it that way idiots making ignorant posts did I'm just looking for input on the MAF problems.

you shouldn't really have any maf problems with an intake install. the main thing that you need to look for is a place for the VSS to plug back into the intake. it is just a little round thing that has a plastic post on the end of it and it fits into a hole on the stock intake. if there isn't a hole for it, that is no big deal. you can just let it hang down.

the injen CAI inducts from inside the bumper on the driver's side and you may need to relocate the coolant tank. i had to on my injen for my 2.0 anyways. any SRI will not require you to relocate anything, but will cause the intake temperatures to be a little higher. that's only a bad thing if you live somewhere that the outside temperatures get higher than about 95-100 degrees. i live in houston where the heat index gets up to 130 in the summer, so a SRI wouldn't be a good idea for me.

a large diameter SRI operating in nominal temps will give you more horsepower than a CAI. that statement is bound to spark a lot of debate, but i am going to say it anyways because it is true. the basic idea of that is the SRI moves the air in a much straighter and direct pattern, and since air has mass, it moves faster in a straight line with less restriction (just like anything else that has mass and some things that don't).

I've heard many people saying they get check engine lights from aftermarket intakes with proteges because, for lack of a better explanation, theres too much air entering the engine? haha. whats this about the vss and what is that exactly?

vehicle speed sensor. for some reason, they decided to put it into the intake on our cars and some aftermarkets have them, some don't. if they don't, the VSS can just dangle in the engine bay. as far as i know, the injen doesn't have a hole for it, but my AEM does have a hole for it. when you pull it out of the stock airbox, keep the little gasket that goes around it.

as far as the code thing goes, i have never had any of my intakes pull codes and i have had a few. i don't see how it could pull too much air naturally aspirated, since the turbo proteges are basically the same as a sedan, just with a turbo and a little tuning and pull way more air past the MAF. you can use turbo protege parts for a naturally aspirated protege with no problems, so i don't see where you would have issues here.

your profile says that you are from PA where it doesn't get that hot, right? if i were you, i would get the SRI.

 wheres this vss at? on the maf? yeah im from pa it gets like 105 sometimes haha but i think i might go with the short ram, and leave that part of the intake infront of the grill intact to blow air onto the SRI's filter too? sound feasible? does this vss serve any purpouse if its just gonna be out in the engine bay anyways?.. and the screws on my MAF are like stripped totally any ideas on how to go about getting that off haha?

Two things...
 
My VSS is hanging and it dosent seem to effect anthing at all. As far as I know the only reason its mounted is so all of the wires are kept neat.
 
Second, the striped screws on your MAF. My intake came with new screws on it. There is a chance yours will too so that when you attach the MAF you dont need to wory about the thread size. That should take care of re attaching your MAF. as far as getting it off of the stock intake, it is possible to apply enough preassure to the head of the screw when attempting to unscrew that the screw will turn anyways. If that fails, bring it to your local hardware store and see if the cant help. I broke the head off a screw on my exhaust tip and when I brought it in and asked someoone to help me, he got the screw right out for me. A warning though, that is a pricey sensor so dont just let the 15 year old shop assistant try to hack  and slash at it. Your gonna want someone with a little know-how.
 
Hope that helped, and good luck with that.

nice thanks for the info. but just a thought, isn't the VSS supposed to control the speedometer? hows that work out?.. yeah i was just checking out the most likley candidate to make it under my hood and says it comes with screws. you guys got any ideas opinons about this?:

it looks nice. weapon r is a good company and i am looking at a set of turbo intercooler pipes from them for my rx7. i like it.

nice any insight on the VSS situation wsoape? i'm not understanding how you can just let it dangle there and have the speedometer work correctly?

i am not sure how, but i never had any problems with my injen intake and it just dangled in the engine bay. my speedo was correct too, because the cop clocked me at 77 in a 60 and that is exactly what my speedo said.

Nice... lol... My spedo works fine too. You feel the power kick in and the spedo heads north. Just seems to work. Any Idea on what that mounting bracket in the picture is... mine came with one but I have no idea what its for....

yeah its to mount it. =p. i belive from the instructions on the site and pics ive seen of them installed it goes near the front left if im not mistaken?

talked to a guy whos put the weapon r on his 2000 protege lx and he said he thinks theres a slot he put the vss in so :).

ok..going back to the previous statement about check engine lights...yeah my intake consantly pulls a code...not sure what it is thought cus the shop i went to who read it...well their book didn't go that high to tell them what it was....and anyways...i think the vss...anyways in my inake it just had a post that i attached it to...and i'm w/ wsoape in that you would be ok to let it dangle but if you can just tie it down

Just so people don't think I'm nuts:

One of the first replies to this question included a picture of one of the presidential candidates with a very negative caption. That is what I was responding to. Our moderator must have deleted the post along with another one which included an inappropriate put down of the person asking for info about the effects of a new intake on his MAF.

Oh haha I know what you're talking about now. I thought you were saying that Ecotec was political hahaha =p.

Is this early april fools or some shit?

if you do not know what the fuck you are talking about don't post with misinformation because you will just make shit worse. this isn't a little deal, i cannot believe so many people believe that the little sensor with a post that goes into your intake is a Vehicle Speed Sensor (VSS) think about it, how is a sensor in the intake going to tell you how fast your vehicle is going? that sensor in question is an Intake Air Temperature (IAT) sensor. It needs to be there or you will throw a MIL. Do not just let it dangle, if there is no hole in the tube to put it drill one. Otherwise fasten it to the filter so it can read the incoming air temp

the VSS is in the transmission, or if you have a 2.0 and ABS, there is no VSS. the ECU gets your speed from the ABS sensors

i am sorry if i was originally misinformed. i didn't intentionally misinform anyone here, i was just telling everyone what i was told, but;

1. you didn't need to be such a cocksucker about it. you could have just pointed it out instead of basically just telling me that i am stupid. you can e-thug all that you want, but it doesn't fly well with me.

2. my old protege had an injen CAI that had no place for the IAT and i left it dangling. i know a lot of people that leave it dangling. i never had any problems in the 40k miles that i put on the intake and never had a CEL.

3. i am not stupid, only slightly misinformed. i got my information from a supposedly reliable source and it was wrong. fucking sue me.

It wasn't directed at just you. I'm surprised it went un-noticed for this many posts.

anyway, leaving the IAT dangling but connected will not throw a MIL, only if you disconnect it. the IAT is one the sensors the ECU uses  to adjust timing advance and fuel trim. so if the temp the IAT is giving the ECU is different than the air entering the intake, you will be hurting your performance.

if the pipe does not have a hole, drill one and stick the IAT in there. it should have a rubber grommet. if not, you can use anything that fits and holds it in the pipe. if you don't feel like going through that trouble, you can fasten the sensor to the outside of the filter so the air moves past it.... some people pull the filter off, throw the sensor in the pipe and put the filter back on. It works but i would not advise this as it will crimp the wires and overtime the vibration would eventually cut the wires.
