Basic MAFT Questions
What is it?
What does it do?
Where does it go?
Where does the xxxx color wire go?
Can I vent with a MAFT?
What MAF can I use?
Can I use a 2g MAFT with a 1g?
Can I use a 1g MAFT with a 2g?

Sorry guys !but am not really sure about this one.What does the MAFT really do and is it a good buy?thanks

im really lost so im sorry if this is a newb question. I have a n/t 1gen, however i have stripped the internals totally rebuilt it with a rebuild kit for a turbo, ive swapped the cams, i have a turbo tranny and all the other stuff. i got the eprom and dsmlink but im really confused about the gm maf thing. is it somthing i have to or should upgrade. i dont understand why on some cars the maf is on the stock intake pipe but others its on the uicp. i bought a new intake pipe from dejon tool its the 1gM dsm and gm mas 3" without the bov tube. so..should i upgrade since mines from the nt anyways. btw im running a 50 trim and ive got 750cc injectors.

The main reason people upgrade to a GM MAF is because it is "less restrictive." However, if you do not have many mods, it is highly unlikely that you will overrun your stock MAF. If you plan to get mildy crazy with the car, it may be something to look into.

The GM MAF is the one you see mounted on the intercooler pipe after the BOV. Because it meters air after the BOV does its thing, you are able to vent the BOV to the atmosphere, which some people desire. This is called Blow-Through.

You can also mount the GM MAF in the stock MAF location, directly after the air filter. Some people argue that this is more restrictive pre-turbo, and they'd rather have the GM MAF after the turbo. This is sometimes called Pull-Through.

Someone had a huge write-up about all this, so just do a search, and I'm sure you'll find better info than I can give.

Good luck!

ok so i read the q and a about maft that wiseman posted (gsx4life) and i understand alittle bit... i need someone to explain to me in begginer/amature/starting to learn language... all the abbreviations are killing me... the reason why is because i am recirculating my bov and i want to vent it to atmosphere....

 

[DSMark]

Well what do you want to know about it? Okay basically your mass on your car now reads air flowing before the turbo and adds fuel the fuel for the X amount of air it reads, it also adds the X amount of fuel for the air entering after the mass from the Blow off valve. When you "vent" your bov, your car is adding fuel for air that isn't there. A maf translater allows you to use a GM (general motors) maf, which reads air before the intake manifold and which is attached to your upper intercooler pipe. Therefore, since it's no longer metering the air before the turbo, it doesn't matter if you recirculate or not because it is adding fuel for the air metered before the intake manifold. Hope this helps out a little bit, I tried to explain as simply as possible.

Ok, I ve put a 2g maf in a 1g. So i was wondering if I could put a 2g GM MAFT in a 1g car and juse wire it the same way I would use for the 2g maf in a 1g? If any one has done this let me know.


Thanks Tony

I am about to buy a 1g gst that has a suck through maf with a translator. I was thinking is it possible to turn it into a blow through? Im sure it is because i have seen a thread about it before but cant seem to find it. Help would be appreciated.

Good question, Ill bump it for you seeing as I would like to know the answer for reference as well.

 

[bryce]

So i got my gm maf and translator in and i also got a new intake pipe and filter. The intake pipe has no holes for any lines. I know now that im going blow thru that i can eliminate my bov recirc. tube. and i know i can put a little filter thing on the line that goes to my valve cover. But what do i do with that other line?

 

[Scott_S]

The other line is for the charcoal canister. if you are worried about emmisions you will need to drill a hole and put that line back in

 

[bryce]

will it effect me in any way if i dont have it attached

 

[Scott_S]

well a little as far as gas mileage is concerned and you will probably have a cel flashing in your face other than that not really

 

[DSMcamaro]

I removed it, no CEL for me.

 

[alex99gst]

You can remove the charcoal canister and then plug the lines. Here is any easy to follow write up:http://www.dsmtuners.com/forums/showthread.php?t=211982:thumb:

Will the car still pass E-Test if I remove the Charcoal Canister? LMK thanks

If they only do a sniffer test them the charcoal canister will have no effect on pass or fail. However if they actually do a visual check for emissions equipment then you will more than likely fail. It's against the law to alter any emissions equipment i.e. EGR, catalytic converter, etc. I would check to see what the procedure is for emissions testing in your area and fix your car up to pass whatever test they do then just change it back after you've passed.

Is the sensor just behind the air filter, in the stock location? I'm going to assume it is and answer this as if it is. The air sensor takes a reading of how much air is flowing into the engine and this is the reading that the ECU uses to determine how much fuel to add.When it takes a reading of the air flowing into the engine in the stock location it is set up w/ the BOV resurculating back into the intake and the sensor takes all of the blown off air as going into the engine. I'm going to make a crude diagram type deal to explain this easier, this is going to be in order from the filter to throttle body. Your intake system goes like this:

KEY: ICP= intercooler piping/
MAS= what ever airflow sensor you have/
IC: intercooler

STOCK: (BOV is blowing back into the intake )
Filter:MAS:intake pipe:Turbo:ICP:IC:BOV:ICP: Throttle body

That is how your setup is from the factory. Your BOV is after your sensor and is venting into the system so your sensor will pick it up. If you are looking for a setup that will vent to the atmosphere you will want a setup like this; with your MAS after the BOV, this way your MAS will not account for the extra air coming into the engine and you will not have the shifting/idle problems with running rich

VENTING SETUP: (bov venting to atmoshpere)
Filter:Intake pipe:Turbo: ICP:IC:BOV:ICP:MAS:ICP:Throttle body

Notice how in the venting setup the MAS is after the BOV. This is the difference if you want to vent. Also you will also either need a new intake pipe w/o the BOV inlet or you will have to plug up the inlet with something. P.S.: You probably could've found all of this out by searching, but i need REP pts. ,,,,, soooo,, if ya don't mind,,,eh,,,, hook a brotha up please good luck with your setup bud!

Yes, it's quite possible. Just go to www.dejonpowerhouse.com. Not only will they have what you need, in any color you want, but imo the quality and price are second to none.


Here is a link to what it'll basically look like.

Very simply, all you have to do is move the GM MAF from in between the turbo inlet and air filter to between the BOV and the throttle body. GSntncT gave you the link if you can't modify your UICP to accept the blowthrough setup. And for future reference it's draw through not suck through. "Suck through" reminds me of the drill sergent from Full Metal Jacket, golf ball, garden hose, you get the picture. Good luck and let us know how it turns out.

 

[Red Man]

Good Details Guys Thanks that helps me too.

 

[GSEclipse620]

This may seem like a pretty newb question but i can't actually find the answer anywhere. What exactly is the difference between a MAS ( actually i know that is your mass air flow sensor ) a Maf/ Maft? As near as I can tell through my reading they all do the same thing. Could someone explain specifically what exactly the perpous of each one is and the differences? Thanks

 

[Apeximprt2nr]

MAS and MAF mean the same thing. Mass Air Flow Sensor. Just different abbreviations.
MAF-T is: Mass Air Flow- Translator. It's used on DSM's running Blow through/ Draw through setups with utilize GM MAS's. The Translator basically "Lets" you run the GM MAS by changing GM MAS language into DSM ECU language. Basically so the ECU and GM MAS understand eachother. That's the best way I could explain it.
