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

I have looked around for the answer to this question, but could not find it anywhere, including other forums. What exactly is a MAFT? I think that it is a program that you use to fine tune your MAF, but I do not know for sure. Would this help in resetting the MAF so that you could use a non-recirculating BOV, because I bought one before I learned that DSM's need a recirculating BOV to run properly.

Its a POS in a box. If I wasn't using a sort-route FMIC where It would be easy for me to re-circ my bov and I didn't have to vent my BOV I would smash it with a hammer.. Its a hacked up POS that is highly inaccurate without major calibration to the GM MAF. the Ver 2 is enharently better with the ability to utilizes the 1g/2g factory MAF's. It does offer the consistencies in airlfow meetering from the clamped baro, so in that respect it is somewhat 'consistent'. But aside from that. Unless you have dsmlink/3.3bar/wideband where you can alter the alirflow sliders to re-tune your LTFT's and calibrate the GM MAF to the factory airflow metering values and tables I personally try and steer everyone away from it as there primary source of fuel mangment..

I was just looking up 3" GM MAFs and it said that if you would like to vent your BOV into the atmosphere, that you could put the MAF after the BOV. Would this be a smart idea? I would think that you could do it, but since you would be releasing so much air, there would be almost no reading by the MAF and the engine would try to suck more air in, making you run lean.

The only way to run a MAF-T setup in blow through is to put the MAF after the BOV. This way the sensor meters the air coming in and you can vent properly without venting air the sensor "thinks it saw" but really didn't. When hooking up the MAF-T, you dial in what size injectors you are using so it will adjust for that and make sure you don't run too lean or rich. Although, I've read using the MAF-T itself for tuning isn't the most reliable thing and would be better to have an S-AFC or DSMLink (which would also add a host of other features and a logger...but will also cost you a bit more than the other options).

I plan on running a MAF-T setup with a Tial BOV and DSMLink in the near future as soon as I save up some money!

What are LTFT's and what would you say is a better source of fuel management?

LFTF's are Long Term Fuel Trims. You could use a 2g maf and a SAFC if you dont want the hassle of a Maf-t setup.

ive searched all nite, please dont give me the link to fullthrottle.com. i want your advice on the settings for my translator based on my mods. hopefully one of you have the same setup as me so i can have a general idea. Mods are as follows: Walbro 255, dejontool mbc, 3 inch catback, maft translator version 2.02 and a 3.5 gm maf. i have no logging software to help me tune. please give your advice

 

[papasapusc]

Would I be able to use a venting BOV with the 2g MAF, and not stall out or run rich if I set it up as a blow through system, or would you need the GM MAF?

I've read of a few people doing it but it's not a good way at all to get a blow thru setup. The best way is to do it right and get the GM MAS and the MAF-T. It'll be much more reliable. Here's a few links about using a 2G MAS in blow thru if you'd like to read about it.

In this one, post #25 will give you the reason why the 2G MAS can't be used in blow thru.

And here's a link with more info than you probably want to know about the stock MAS.

Hope some of this helps you! But I wouldn't run the stock MAS in blow thru or draw thru. Just go pick up a GM MAS and MAF-T.

I read through the MAFT FAQ, so please don't flame me to death. I'm just a bit confused, and don't want to make any purchase's untill I know everything first.

I read that the MAFT is a piggy-back fuel tunning device, somewhat along the lines of the SAFC's. This would fit my needs as it's adjustments are -/+ 60% vs the -/+ 50% of the SAFC's. It also allows me to vent as well, meaning I can finally repositon my BOV.


My question pertains to the Gen 2 translater. The FAQ has a link to a version 2.0 tuning guide, but I'm confused as to whether it's a VERSION 2.0 of the 1st gen MAFT translator, or if it's the Gen 2 device.

The Gen 2 looks as though it's much more of an upgrade of the Gen 1, as it's got buttons for tuning instead of dials on the Gen 1's iirc.

Also, I would only need the Gen 2 translater correct? I wouldn't need the gen 1 box correct?

Anyone that has a Gen 2, please come in and give me some insite on how it works and if it's still a real PITA to tune like the 1st Gen was (based upon the FAQ). Thanks!

 

[LTUDSM]

i would say go for it,is really easy to tune with,the gen2 version is way better then the 1st one,it has more tuning capability s then SAFC OR SAFCII

 

[Kevin TSI]

Is it alright to have the GM MAS straight out of the throttle body? I just wanted to check before I make a mistake.

 

[talon210]

I just bought a MAF translator and I am going to hook it all up tomorrow with the GM mas, I have everything, but Im not exactly sure were to find the tach signal for the white wire coming from the translator. I know it says ecu pin 58 or power transistor pin 4 but where is that in the engine bay? Is there an easier place to find the tach signal?
thanks

 

[papasapusc]

Thank you. Those links are great. I feel like I understand a lot better now about MAF-T, and I think that I'm going to invest in it.

[snowborder714]

Glad I could help! I agree with you and am going to invest in it once I get the money.

MAFT can adjust idle,mid,wot fuel trims like a safc... adjusting the knobs can be a pain, if you install the MAFT under the hood... If you set all of your MAFT to zero, you can use a SAFC or DSMLINK to tune instead of the MAFT.

Personally, I'm happy with MAFT's capability to tune, but running over 400whp I wouldn't recommend it, you're getting to the point where DSMLINK's timing capabilities come in handy.

So, can't you adjust the tuning with a DSMLink without the MAFT? I wonder if anyone has tried to run a recirculating bov with DSMLink and without a MAFT.

 

[snowborder714]

DSMLink will work without the MAF-T. DSMLink is just better than an S-AFC because of all the features and adjustability and tuning options.

Yes, I'm quite sure there are people out there running DSMLink with a recirculating bov.

The MAF-T is only needed if you replace the stock MAS with a GM MAF. Since the GM MAF sends its signal out for a GM ECU, we need to convert it so our ECU's will read that signal.

ok.. im in the prosess of getting my car ready for some upgrades, and i came across a Gm maf for 40$ new, and now im about to order the maft. right now i have the stock turbo and injectors and everything else along with that.
i have a HKS bov, dejon UICP(for the gm maf) 3" turbo back, and an ebay intake.
i dont have anything to log with and i dont plan on trying to tune my car with the maft but i do want to put it in so everything is ready when i get my bigger setup.

i just want to know if im going to have any problems with my car untill i get DSMlink(will be a few months) and if i should just leave everything 0'ed out on the maft, or what should i do as far a haveing a blow though setup and keep the car running normal

If you are going to upgrade make sure you have something to log with

 

[98GSt_4life]

i know, thats why i said im getting the DSMlink, but what i wanted to know is if i can still intall it and zero everything out and have no problems with driveability or reliability, being as it will be a wile befor i have the money for dsmlink

i am also having fitment problems with my intake sence i got an ebay knock off
so i wanted to get reid of the 2g mas to clean things up along with vent my bov.

 

[wret]

You can run the MAFT "zeroed" to just simulate the MAS. It will run fine with stock turbo and injectors.

 

[98GSt_4life]

ok thanks..

one other question, what about the 2 sensers that i lose?(temp and something else i think)
will that have a negative effect sence i live in florida and no 2 days are ever the same.

Posting here to avoid a repost...

I have purchased the MAFT Gen2 and installed it properly. The car idles, it drives, builds boost, all that lovely stuff. For information about my setup, please see my profile.

My question is this: Where on the web can I find some guidance in tuning the MAFT? I know that it is a powerful tool, and I hope I'm not in over my head. Fullthrottletech.com just points to the manual...

The motor just seems to hit a wall at 3000rpm and stutters until I back off to half throttle, otherwise, at part throttle, it works close to the way it probably should. It also seems to work a bit better in first gear (auto) rather than running in drive.

Anyway, is there anything like a step-by-step, hold your little newbie hand kind of guide out there? Or are there any people on these forums that have already street tuned their 4G63 with the Gen2 that can relate their experiences?

Please help me. There is a V8 Meathead Festival on Easter, and I really want to have a little fun with them...any advice at all would be appreciated! Thanks in advance...

im finally looking to integrate the MAFT setup into my setup, and i have a couple of questions for you guys. first off I have the Ebay 1g long route FMIC kit, and i believe i would be ok with just cutting out the section on the upper intercooler pipe were the GM maf is gunna sit and set it in with a couple of reducers correct?? i dont think that this would be much of a problem i belive ive seen people do that instead of buying the actuall pipe that accepts the GM mas.. second question. after buying the gm mas the MAFT and a tial bov im kinda short on money now and i need an intake that doesnt have a bov recirculation tube and one that doesnt obviously have the stock mas positioniing on it.. so im looking to go a little bit cheaper on this part. any one know were i can get a cheap intake pipe that will work with the blow thru setup for a decent price?

 

[Talesin]

Most people will just Home Depot it at that point. Cheapass cone filter and a few PVC pipe bends. Could also just leave your stock intake in place for the time being, and duct tape over the recirculation fitting, if your entire point for the exercise is to get the ricey hiss, and not to open up the intake system. If you just want the intake system opened up, you can replace the stock MAS with a simple clamp-on filter and leave your BOV recirculated.

 

[tkelly27]

1st question, should work fine. Measuer the intake pipe size first and get couplers though.

2nd question, PVC works wonders. You could also nab something in a junkyard. The intake hose to a ford SC is 3" and makes a 45* angle with a flex section. 4.6L fords have 3" 90* bends on them. You can do it!!!

 

[Sinclair159]

well i already have a Dejon hard intake pipe, so maybe i could just plug up the recirc tube, but when i take the mas off of my intake can i just buy a filter that will fit on there??
