sorry if it has been reposted anyhoo today I got one for 20 bucks at junk yard and im not sure what size it is 80 ?

Okay will it work with 98 Infiniti I30 , if that so hasnt anyone done write up or pictures of how to do it yourself.

I think its two ground to one ground , white to the signal and pos is pos ?

Can anyone help me out ...thanks

I wanna know too. As long as the can pipes and t b are similar diameter... I might have to do this with my mech friends help

Sorry for the delay, I was going to give you a reply but was short on time.

To pull it off, you'll likely need some sort of piggy back fuel controller or a new flash with that particular MAF's outputs.

Basically, just bolting it on your car likely won't run or at least won't run properly as that MAF won't likely put out the proper signal for the stock ECU. You would need to get that particular MAF mapped to know what voltage it puts or for what particular airflow is going through it then program that into the ECU.

Personally... I wouldn't even mess with it. Unless you're going with boost and are making enough power that the stock MAF is maxed there simply would be no point and there would be many more headaches than its worth.

see your not actually using the maf sensor part, just the cylinder part. the actual heating element that's cooled by the amount of air passing thru transfers that info to the ecu and delivers fuel accordingly, is removable. N e ways ur only using the maf can so more air can flow thru. More airflow means more fuel mixture and that equals horsepower... In theory. A decent mechanic helps as well.

Even if you took the stock MAF sensor and put it into a larger housing, that will change the amount of air that the ECU "sees' therefore changing the tuning.

Simply put, any changes to the MAF beside a stock replacement can and most likely will require an ECU tune.

Also, unless you're boosted there's simply little to no gains to be had from making the MAF housing larger. Its not that big of a restriction, especially consider housings of a similar size can handle around 500 hp (Z32 style).

It has been dyno proven that there is a 10whp gain to be had when doing this when NA...on a 3.5, you can gain about 7 whp on the 3.0, but it really depends on the kind of tuning you are after.

By changing the MAF... or changing the MAF and retuning?

awesome , i think i ll go to that direction and makes me much more easier than doin more work on another maf.

I have some problem to log in . is there any way i can get ahold of him like via email or something else like that.

thanks

Isn't the ecu in the 5.5 gen a learning cpu where it will change air/fuel to optimize performance. I noticed after installing my cai that it seemed to get better over the course of a few long drives... is it just me or does the ecu adjust itself. So what I'm saying is if you dropped in just a bigger housing the ecu would reconize more air and automaticaly adjust the fuel to match the air and using a safc would further optimize perfomance.

all cars can make adjustments to a point, your car obviously notice the increase in air, so it adjusted to a point. But with this mod will require an AFC to tune it out and make the proper adjustments so as not to hurt your engine or even blow it.

Dave , didnt u read my currently post about the guy who makes maf ....I still need email to get ahold of him thanks.

I bet that's where the most of the power gains come from... not to say its impossible to get gains from a MAF swap. I have actually heard of someone making the housing larger using the same sensor with a turbo setup and actually tuning it that way but that was with a turbo setup so is a bit different.

exactly... Once again u will get better flow with a bigger maf can, but, u need to change the flex tube leading to the throttlebody to a matching size. Also a bigger throttlebody or atleast a ported one to maintain the constant airflow. U can't have the can big and then the flextube small cuz that will jus slow down the air going thru. And its not such a huge mod that u need to fine tune ur ecu for it... Its just like advanced intake. Its still getting air at atmospheric pressure just making it more available.

remember the difference between the 99 and 2000 models where the 30 hp gain comes from? The intake manifold. Just making the air available during certain rpms...

Its not a flow deal. Unless Nissan put a horribly undersized MAF on the engine it won't be starting for air. A cold air intake will probably get you way more gains than changing the MAF will.

Also, you do need to retune if you change the MAF because the readings will be completely different. If I remember correctly, going larger will cause the sensor to meter less air than the engine is truly getting causing it to run a little richer. Go smaller and it will cause the opposite of course.

Now, Nissan does run the engines a bit rich stock so it could be possible to size the MAF housing properly to make it run a little leaner therefore increasing power a little bit but that would take quite a bit of work finding out the exact size needed (which should be smaller, not larger).

The majority of those gains from changing the MAF are likely from retuning the engine to accept that MAF. You could probably see similar gains by keeping the stock MAF and fine tuning the ECU.

nissan makes their cars performance to specifications not the max power output possible. Maybe I'm wrong and u do need to tune the ecu when u swap the can. But im telling u from a mechanic friend of mine whose been tuning cars for 30 years that the way i said will get u a little more hp. The can upgrade isnt supposed to be a cannon from a peashooter. U swap the maf the flex tube and the throttle body for slightly larger and equal diameter ones. U get more airflow in the higher rpms where its needed. But what do i know... I only have like 60 posts on nico
