Dude if your KA is spinning 25000 rpms then you have 1. either figured out something the whole world wants to know, or 2. you're a moron. I'm going with 2 because you can't read or comprehend.

Ugggggggggggggggggggggggggggggggggggggghhhhhhhhhhh hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

[smelly240]

was i like speaking another language or something?

[DrifteRs13]

ok the prong was bent, didnt do anythign to my car still ran fine, i dont want a distributor, i just want what is gonna fix it and i wanted some opinions so thanks i did fix it. i just needed a new cable for the maf sensor.

thanks guys i appriciate all the help.
just needed to make sure it wasnt somehting costly.

[airsoft]

^hahahaha

good job.

but i believe it was explained a long time before somewhere on teh 2nd post on page one.

oh well, cars fixed. On with the show!

[smelly240]

no way!

[MELLO*SOS]

OMFG it was the MAF after all?!



Glad you, uh, got it fixed. Sorry your shop had you waste time on the Distributor and Cat/Exhaust. I'd find a new shop who knows Nissans a little better.

I would find a shop that knows anything. Most every car, built since the 80s, has a MAF sensor.

[DrifteRs13]

i know that is why i took it there, siad in big letters WE DO IT ALL lol car still not fixed i just need the actual part that plugs into the maf anyone know where to get one?

[DrifteRs13]

ok if i got a n60 maf sensor would that run poorly without a diffrent fuel system? all i need is the harness fot mine but i cant find one anywere?

[Kn1ves]

Junkyard x30

there, i already said it 30 times


watch out for his next thread/post, which is sure to be
'whats that red dot thing mean below my post count'

Where do you live, so I can avoid the idiot epidemic that's sweeping your hometown?

Sheesh. Listen guy, you already admitted that you have a damaged MAF sensor. Let's get something straight.

THE MAF SENSOR IS NOT THE SAME AS THE PLUG THAT GOES INTO THE MAF SENSOR. THESE ARE TWO TOTALLY SEPARATE PARTS!!

The plug is part of an electrical harness that is connected to various components, namely the MAF sensor. If you have a missing prong inside the MAF sensor then you don't need to replace the wiring harness or the connector that hooks up to the MAF. YOU NEED TO REPLACE THE MAF SENSOR!!! It's that entire metal piece that fits in between your intake piping just after your filter. DO NOT START CUTTING THE WIRING HARNESS AND LOOKING FOR A REPLACEMENT, YOU DON'T NEED THAT PIECE.

I'm sorry for yelling but it seems like you either lack the ability to understand what you read or maybe you only have a 2 second memory and conveniently forget the last helpful post that had the answer you need.

Now this might confuse you but try to keep up.

If you have a faulty wiring harness connector, then you can go to pretty much any local junk yard, find out if they have any 240s, and go cut the MAF sensor connector from the wiring harness off, but make sure you cut it so that you have about 3 inches of wiring to work with. Then go home and butt splice the matching color wires together from where your old connector used to be. This should solve the connector problem (if that's what you have).

[smelly240]

thank you for clearing that up for him (i thought i did that like 10 times LOL )

[Dream240]

You did....I just figured he could use one more information salvo.....

[DrifteRs13]

no i compleatly understand i dont think you understand, i found one that comes wiht everything new harness and sensor all i aked was if i got a n60 would it run poorly? simple quesations to you people and you guys make them complicated because you think you know who i am or somehitng like that. i havent been working wiht nissan that long, sorry, i use to own alot of hondas and they dont have mafs on the intake. so if you want to critisize go ahead do it to somone who is honistly stupid not someone who just hasnt hade the exp. yet.

Okay easy answer. I'm only responding to your posts! You never stated in full detail what you had in your possesion!

That is not the same as saying you found one that comes with everything. You need to learn to be more specific from the get go. Giving us fragments of info post by post will easily get the other posters frustrated thus, the flames.

As far as knowing you, obviously i don't personally know you nor do I care to. Hence the flames. Dude you gotta understand that a forum is meant for impersonal bashing. If you take this stuff seriously then you got some serious personal issues. Really WHO THE FUCK CARES WHAT SOMEONE ON HERE SAYS ABOUT YOU!! Will I ever meet you? NO.

It's the same as driving on the I-5 coming from San Fran. and getting caught picking your nose by another driver. It's embarrassing but who the fuck cares?? You'll never see them again in your whole life. Let it go!!

And i don't know what hondas you drive but if they came from Japan and not Mars they have MAFS. Most, if not all, of them are located somehwere on the intake pipe. I'm talking stock cars here not heavily modified space shuttles.

Peace

[DrifteRs13]

i hear you dude its just frustrating trying to get this damn car to work when ppl are just flaming and not helping or getting mad they dont have to post, and no the maf in under the intake manifold not the actual intake. but anyways. do you knwo of any place that sell aoem maf for cheep

[DrifteRs13]

<ok if i got a n60 maf sensor would that run poorly> and yes i did specify the sensor then i said all i neeed it the harness

[Dream240]

Just check ebay. There's quite a few on there.

BAM done.

[inertiaticism]

Cut the harness off of a wrecked car.
Then put it onto your car. Now your harness is not bad anymore.

If you end up needing a MAF, just buy a regular KA MAF until you get your problems sorted out, then maybe upgrading to an N60 would be a good idea later on when you get some supporting mods done.
That way you've got a spare stock MAF hanging out if you need to return it to stock, or if your new MAF takes a dump and strands you.

[smelly240]

an n60 maf wont work without something to change your compter or the maf signal (tune or a AFC)

and an n60 maf wont give you any performance at all... it's used to exceed 275HP (the stock maf tops out there), not to make more power.

theres a thread on FA about this - by Enthalpy from years ago. Read it.

[DrifteRs13]

all i need is somethign to pull it out of limp mode not more power but i just bid on a oem one on ebay. thanks

[MELLO*SOS]

Dude you need to use the same exact MAF as what was on the car originally. Just replace it with another KA maf and you'll be good to go. Note the DOHC and SOHC mafs are different, please be sure to get the right one!

This thread is fun and I'm bored, so I'll give you a MAF explanation so you can learn why this is. And have a better understanding of what's going on...

MAF newbs read up!

Each MAF sensor (ka/de, ka/e, n60, z32, q45, etc) has a unique calibration. This calibration translates an airflow measurement (#kg/s worth of air) into a voltage between 0v and 5v for the ECU. The ECU has a matching calibration table stored in it's memory (called a VQ table), so that it can quickly translate the voltage back into a measurement (kg/s of air).

Lets assume your stock KA maf was reporting 3.5v @ 5000rpm to the ECU. If you were to replace the MAF with a differently calibrated MAF, such as a Z32 or n60, it may only report 2.5v @ 5000rpm for the same amount of air. The ECU doesn't have any way to know you swapped the MAF, so when it looks up 2.5v in the VQ table for the stock MAF, it will only allocate fuel for "2.5v" worth of air, instead of the actual 3.5v! Obviously this is going to create a very lean mixture since you're short changing the motor on needed fuel.

Now during idle and part-throttle cruise, the ECU runs in "closed loop" mode, this means it continuously monitors the O2 sensor to see if the mixture is a little too rich or a little too lean. The o2 sensor is a fine-tuning adjustment. It uses this feedback information to fine-tune the mixture (short and long term fuel trim) a little richer or a little leaner.

But! During higher load & wide open throttle runs, the ECU switches into "open loop" mode. This means it completely ignores the O2 sensor output, and completely relies on the MAF sensor (well, along with RPM, TPS %, ECT temp, etc) to calculate fuel delivery!

What this means is that the ECU will have no way to know it's running too lean (except excessive knock & elevated engine temp, which will cause it to retard ignition spark timing which seriously reduces power output). It will most likely in due time melt a hole in your piston, or otherwise destroy the motor from knock/pre-ignition. Leaner mixtures burn hotter, and leave more heat in the combustion chamber for the next cycle to deal with.

Of course if you have a magical tool that lets you reprogram the VQ table in the ECU, then you have the freedom to use just about any MAF sensor you can get your hands on. This is how people are able to use N60 or Z32 maf on their "stock" ecu -- it's been chipped or reprogrammed somehow. Instead of reprogramming the ecu, some guys will run the Apexi S-AFC to use the z32 maf with stock ecu. This is a somewhat half-assed approach to tuning, since the ECU still has the wrong VQ calibration table. (sorry if anyone is offended, but you know it's the truth)

So for these reasons it's important that you use the exact same MAF as the ECU is expecting, otherwise you'll confuse it and it'll end up costing you your motor. In a less extreme case, you may not burn a piston, but you'll definitely have a bad idle, sputtering, trouble starting, poor acceleration and terrible fuel economy.. All from try to use a n60 maf when you should have just stuck with the KA maf.

The same logic is true for injectors, you can't just slap in a new set of 550cc injectors when the ECU is expecting 270cc's... Things have to be calibrated to work with each other, you can't just throw stuff together and hope it works. The ECU and it's sensors don't work like the USB port on your computer. If you install a new or different piece of "hardware" you need to put a new "driver" on the computer!

GL I hope you learned something about MAF sensors with this thread.

[DrifteRs13]

thanks, i like i said imnew to the 240sx and nissan stuff so i just gotta get some trial and error down. again thanks

[!Zar!]

There was zero need for trial and error.

You stated a problem.

Everyone and there mother gave you the info you needed to fix it.

You wasted more money/time on random bs.

Then you finally gave in and checked your maf out, you fixed it.

Lesson for the day. When you have 10+ people all telling you the same thing, then chances are they are rite.

[MELLO*SOS]

Yep. Check out my post & the others in here and it should help you understand a little more.
Obligatory note: This kind of info has been covered quite a bit also, be sure to search around next time before asking!

GL on you project & happy holidays.

[DrifteRs13]

same to you peace

[DrifteRs13]

on that ebay like for the 91 maf will that fit on my 93 it looks diffrent?

[!Zar!]

Wtf are you speaking.

They are the EXACT same.

Please for the love of all things, learn how to speak english.
