na maf wiring pin out

[GalantGst]

some one please tell me what the na maf pin outs are i have a galant should be the same as a t/e/l .

mavitsky had some shitty ass intructions . the thing says att 7th pin to the maf and to the ecu that dont tell me shit pin 6 is air flow sensor every car has that.


i should be good with the wire pin out for the na maf and ill write my own guide
no effence to mavitskiy

Shitty ass instructions huh? I wonder why i help people like you sometimes.

If you want to know the difference between an na maf and a turbo maf it's this simple. The turbo maf has a 7th wire coming from it back to the ecu that the nt doesn't have. The instructions I put into the tech article were easy enough for me to understand, maybe I should try to make it a little easier for you though next time. I thought that..

7th wire from mas - the 7th wire from the mas needs to be run back to pin number 6

....was pretty easy to understand, especially after I responded to your direct e-mail about it. I did the wiring by hand on my own car and took that wiring harness on to win a bracket class even at the 2002 DSM Shootout. Apparently though neither of those explanations were good enough for you even though I've done the work firsthand. The only reason I even answered this thread is because I'm sure someone else will have this same question down the line as well and this way I'd have a thread I could point them too.

Good luck with your car, and good luck trying to get anymore help from me. God help us all if you write a how-to with this type of grammar and punctuation.:thumbdown

If you don't believe me here are the original wiring diagrams that show the difference.

Well I did use ur instuctions for a guideline on how to turbo mine. I guess there not "shitty" but it could be improved.

I am at work right now I dint look at the ecu harness but from this site
http://www.ecanfix.com/users/mdhamilton/1991tntecu.html ecu pin # 6 is air flow sensor. The stock one has to have it as well right?

This is what the turbo pin outs at the maf plug are

1 - Idle position switch
2 - Air flow sensor
3 - MPI control relay
4 - 5V power supply for sensors
5 - None
6 - Ground for sensors
7 - Barometric pressure sensor
8 - Intake air temp sensor

Can u list the pin outs for the na maf for me

What would I use to hook up the additional wire to the maf? what type of pin or what ever I need to make the connection at the ecu plug?


From what I understand I see 6 wires coming out the na maf.The turbo maf plug that I see a pic on the factory service manual thre

I found this on the site and made it alot easier to wire the resistor pack.

As for the resistor pack, it's simple.
1) Buy a resistor pack.
2) Open up the wire harness that runs to each injector. You will find 2 wires going to the plug.
3) Cut all the thick yellow wire running to EACH injector.
4) Take the white wire from the injector pack and connect it to just one of the wires you just cut. Make sure it is the one that runs TO the car, not to the injector.
5) Connect all 4 black wires from the injector resistor pack to the wires running to the injectors. Order doesn't matter





Thanks

looking at the diagrams i came up with the following please correct me if im wrong

1g na pin outs

1)air flow sensor
2)mpi control
3)5v power
4)ground
5)barometric
6)intake air


so this means im missing volume air flow right for 2g or a idle postition switch for 1g?

i just thought u had to bridge pin 7 with pin 6 and ur good to go..??

 

[GalantGst]

some type of bridging would make sense because pin 6 on the ecu is air flow sensor and im almost certain even the na one has to have that. hopefully mavitskiy can clear this up

 

[mavisky]

Okay, look at the two schematics i posted. You can clearly see that the Turbo diagram shows another wire coming from the mass air sensor that goes to pin #6, what exactly it does I'm not 100% sure, but I do know that on the NT schematic there is no wire at all coming from the mas that goes to pin #6. I wish I could tell you exactly what that extra wire does, I've heard various rumors, but regardless, it's looking for a signal on that line and you'd better find a way to provide it. It also looks like its a separate entity within the mas, basically its a signal you couldn't duplicate by splicing into another wire. You're going to have to run a wire from the mas to the ecu, how you go about it is another issue. I got ahold of the wiring harness side of the plug and simply re-wired it and ran a separate wire back to the ecu at pin #6.

I know that mike hamilton's site says that pin #6 is an airflow signal, but there is no corresponding wire on an nt wiring harness, at least not one that goes to the mas. Forgive me if I don't know every last little detail, I did the wiring over 2 1/2 years ago and have since switched to a full engine wiring harness from a 93 awd to reduce any bad soldering issues I had originally run into. Nothing like running down the quarter mile only to have your ecu switch off because one of the soldered connections you made on the power supply side shook loose.

pin 6 does not mean its pin 6 on the ecu. if u look on the factory manual go under the fuel section it shows u all the maf wires and sensors 6 means the pin 6 on the maf harness.the color is what goes to the ecu.

correct me if im wrong but im pretty sure im not.

dam no one knows how to do this?every other post i see its some one turboing their na.

 

[mavisky]

Look at the schematics i posted. The number next to the large rectangle (which represents the ecu) is the pin number on the ecu. In this case the number is 6. For christsakes, I don't know what other proof you want. I did it exactly like this, my car ran completely perfect, what other proof do you need. I've helped many other people do this and all of their cars have worked fine. I don't see what your problem is. If you know more about this than I do, fine, do it your way. I did it my way and so have many others, all of our cars ran fine. I feel like I'm arguing with a brick wall, I've told you so many times exactly what you need to do, and everytime you reply with "I know I haven't done it, and I know I may not know exactly what needs done, but even though you did it that way and your car worked, I don't think your directions are correct."

edit here: open up the turbo wiring harness picture. Zoom in so you can see everything nice and clear. See the number 1 right next to the small box that represents the mass air sensor? Now look to the left of that box and you'll see the 8 wire pin (of which only 7 are used, there is nothing coming out of maf pin 5 at all) and you'll see that the number 1 tells you that the wire that needs to be added is located in the #1 position on the maf plug. If you follow the wire that I highlighted you'll see where it goes back to the ecu at #6. That's the pin number on the ecu.

cliff's notes space #1 on maf plug goes to pin #6 on ecu.

No one is ####ing arguing im just trying to make sure what im reading was correct I told u I was not home I could not check it out. I Just checked out the plug of the ecu your right the wire is not there. I thought it should be there because the 1gna pinouts for th ecu say pin 6 is the air flow sensor.

now i just gotta find a connector to take 1 pin off of.

thanks

Don't take mike hamilton's website as the gospel, I've caught more than a few small mistakes on there.

You can't just add a pin to the maf, you're dealing with a 6 spot plug and an 8 spot plug, without the complete plug it won't connect and lock onto the maf. You need to take the maf plug off of a turbo wiring harness (if you can't find one pm me) and attach 6 of the wires from the harness to the turbo plug. Then you need to add the last wire (from slot 1) and run it back to pin 6 on the ecu. You should be able to get a pin for the ecu harness from somewhere like radio shack. The good news is that the wires for the maf are the same other than that additional wire. So your nt maf slots 1-2-3 on top and 4-5-6on the bottom will turn into slots 2-3-4 on top and 6-7-8 on the bottom on the turbo maf plug. Then like i said run back slot 1 to the ecu separately.

i cant find that pin at radio shack.IM gonna try to get my friend to let me take out of of his ac or some bs solenoid one...

the people with that ecu pin out guide is a ####ing moron I have to email his ass.

The thing is im hooking it up to a 2g maf since I dont have a 1g maf or the snorkel for it.


this is what i have till now


1)air flow sensor
2) mpi control
3)5v power
4)ground
5)barometric
6)intake air

and the one thats not there that u told me to add the wire on the 1g turbo its called idle postion and on 2g its called volume air fow


i have the pin outs for the 2g so it should work out great.

my pm shi dont work because i have a email email adress the one i signed up with is my friends.
my aim screen name is skeletal29

 

[na90dsm]

ive talked to mavisky abotu many a things on ere. he knows what hes doing. without him and help from othere i wouldnt knwo half of what i do now


also are you tryign to hook up a 2g mas with 1g mas diagrams. youll have to look at the wiring diagrams for the 2g -1g mas conversions. you have to make a harness for it if i remember correctly.

yea i got the diagram already my first problem was i dint know what each wire was now i do.
i cant make an adapter i dont have either clips so ill just use female clips from strass put it in there and fill the connector hole with rtv

I did that with a friends and the only problem is that you have to be really careful about the soldering. It's easy to solder the wires to multiple pins if you're not careful.

i just finished hooking everything back. the extra wire is not hooked up yet i dotn have enough light but i started th car no cel lights or anything but the idle was lumpy and 2 of my injectors started leaking
will it run like it at idle with out that extra wire? i should have it in tomm i gotta remove one of the ac wire pins and use it for that extra wire or is there a easier way u know of?

my car will idle with the mas unplugged, that doesn't prove much.

 

[GalantGst]

ok i got it running i totally forgot about the hose for the bov sucking in mad unmetered air. runs great i just gotta wire that extra wire to the ecu.

good shit mavitskiy i love this thing... ill have pics up tommorrow
