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

 

[Skusssssh]

well here it is what does a maft do? in know its a translator and that it has something to do with the bov venting back to the intake rather than the atmosphere. but can someone explain to me what it does as well as how.

the reason i am asking well i cause i want to know what it can do for my 2g eclipse.
i plan on doing a 1g swap. my goal is to put 350 hp to the ground. so let me know what you great people think.

The "maft" as you like to put it is actually two things... Part a consists of a 3" gm maf sensor. Part b consists of the translator. As for what it can do for your car quite a few things, mainly it allows you to blow off to the atmosphere, has some tuning adjustments for bigger injectors, and all around flows better..

 

[ivanr4g63]

The Maf Translator or "MAFT" allows you to run a bigger and better Air flow sensor wich is the GM MAF sensor, wich by default comes in a 3" diameter unit, and also can be found in 3.5" diameter.

This MAF sensor generally found in many newer GM vehicles with 6 and 8 cilinder motors, flows up to 300% more air than a Mitsubishi turbo 1st Gen Maf sensor. so the upgrade is obvious...

This will allow you to "measure" more, and more accurately the air been fed into the engine, as you can imagine this unit is made for GM vehicles only, thus why our cars need a Translator, wich enables the mitsu ECU to understand the readings beeing picked up be the GM unit.

Now, the translator has been updated after years of research, it now allows to "tune" your car by adding switches to control for: compensate for fuel, Set you injector size, modify air flow signal (you lean or richen your mixture with the help of a datta logger) among other features...

Also if you install the GM MAF after the BOV, you will be able to vent with no side effects such as iddle issues and such, this is also known as "Blow Thru Setup"

Hope this helps.

MafT Tuners: Feel free to add more details that I probably missed.

PS: for a 350 whp goal, your stock 2g MAF 'should' be good, but every little bit helps, so good luck.

ok well thanks for the info on the maft. the next question is where do i need to go to get something like that i am sure its not something that i can get at some auto parts store or is it.

thanks for the info.

Just search around on sites, there are plenty of sites selling it.

 

[turbo98eclipse]

ebay is always good

I know that this may have already been posted in tech tips but looking for detials on placing Translater in the car. I have recently bought the 6ft extension cable from SBR but not for ssure what to do next someone please help.

Thanks to all

There you go, bro. Did this same thing on my GS-T, everything's neat and clean.

Yes, please post some pics especially of the wiring.

 

[Drifter27_04]

What are some different areas you guys placed the MAFT at? I am looking to hide mine and thought of the glovebox but I currently have my alarm system mounted there as well as the shift light box. If I am not able to do that I have thought of the middle console area (looking at this location because of the convenience.

I'll go snap a few pics for ya. I didn't really care to hide my maft box.

 

[RiceKiller_TSi]

I cut off the harness at the end of the extension and spliced/ soldered it back together once I got the wires through the firewall at the steering column grommet.
The blue wire is the rpm tap.

I didn't care to hide my box I just wanted it to be within reach for changing the settings.

I also didn't have to run as much wiring as I would have had to to get it into the glove box or center console.

 

[spoolup]

I extended mine into the car when I first got it. About 2 years ago. All I did was cut the end off of both harnesses and and extend the wires. Its easy to get the harness thru a spare hole somewhere on the firewall, the hard part is fitting the connectors. That why the method I used was more convient. There are several threads with pictures with installs in the glove box, I chose the center console but have since moved it under the dash all together since I do not need to adjust it at all since I am using DSMlink. Just besure to route it away from spark plug wires and if you have a MSD, the MSD wiring. They like to add interferance.

Well two days ago i ordered my Maf translator, GM MAF and couplers. See profile for other mods. First thing is that i currently have a 2G maf on my 1G so obviously i have the 2g MAF plug on my wiring and dont want to have to splice again. I was assured by full throttle that in there newest version of the translator the only thing differnt is the connector. So i went ahead and ordered the 2G version of it. Which brings me to my first question, I see in the instructions how to set up for injector compensation there differnt settings for both 1g and 2g. Im going to assume that i would use the settings for the 2G sense thats what model translator i have? I also have 750cc injectors that i currently FINALLY got tuned with only a SAFC (good WOT but partial throttle is still rough somtimes.) Should i even mess with doing the whole settings on the MAFT and go through the process of retuning everything all over again? im just not sure its worth the hassle of it considering it took about a month straight on the SAFC to get things correct for just driving around and the idle is almost perfect somhow . The real reason i got this setup was mainly so that i dont have to mess with creating a return tube for the BOV sense i got short route piping for my fmic and also so i had the freedom to make a cold air intake for the turbo insted of sticking with virtually stock options. Now with that in mind and the fact i almost have it tuned perfect for where im at should i start over and use the MAFT for tuning and SAFC for fine tuning or should i just leave the RPM wire unhooked and zero out the MAF so all it does is allow me to vent and use a custom cold air? What im kinda looking for is people with past experiance with big injectors like the 750's with a MAFT and SAFC and how they would suggest works best. -Ryan

Keep all your settings on the SAFC and zero out the MAFT. Here are 2 other threads about the MAFT and SAFC.

Use the 1g settings. Since you are using the 1g ecu and the only thing you have really changed is the plug it will still read like a 1g would. Then just set the maft for 750's leave everything else zeroed out and enjoy your current tune.

 

[joosdawg]

so if im just going to use the SAFC for tuning wouldnt i just set the MAFT for 450's sense thats stock and then it will send the regular signal and the SAFC will take care of the minipulations? Then of course leave the rest of the settings zeroed out. Also if i use it like that do i still need to tap for the RPM wire? if these are dumb questions sorry because i just am excited and want to have a plan for when i recive all my goodies thanks for the links btw

Yes yes, sorry set it for 450's not 750's not really paying attention when I wrote that. You still have to tap the wire that goes to the cas(white wire I believe) and the puple wire doesn't get used(it might be the other way around I haven't had a maft in my car for a while now).

 

[Lordpaxin]

Right the purple isnt used.
you need the other wire, tapped in for it to function properly.


I had Maft + SafcII
I had the Maft set by the book for the 660cc injectors I was running, and used to Afc for fine tune.

 

[Talesin]

Purple is for a dry nitrous enrichment or methanol/propane injection lean-out... if that wire gets signal in the 'other' mode (can't remember if it's MAF or RPM mode), it activates the AUX setting in that mode to richen or lean the A/F mixture. The white wire needs to be tapped into a line getting a tacho/rpm signal.

Use the 1G settings. I'd set the MAF-T for your injectors and just use the SAFC to get the fine-tune in.

 

[joosdawg]

Great comments guys thanks for all the help so far. I think i might just set the MAFT to the injectors then and use the SAFC to fine tune like some of you guys have done. Seems to be worth it and a bit easier also.

I didn;t get instructions when i recieved my maf-t. How do i zero out the knobs and which one is the injector selector? I have 510's so how would i set my maf-t up for them?

Controls:
The Translator has the following controls:
MODE SWITCH – a 4 section "dip switch" for setting the basic vehicle/translator parameters. Turn the engine off when making changes to the MODE switch.
BASE – this 16 position (0-F) dial is used to set the general airflow scaling. This adjustment affects the entire operating range and is generally used to match the Translator and MAF to the selected injector size.
IDLE – This 16 position (0-F) dial is used to adjust the airflow signal during engine idle conditions. It can also be used to compensate for modified PCV (crankcase vent) and fuel pressure setups.
MID - This 16 position (0-F) dial is used to adjust the airflow signal during moderate acceleration conditions.
WOT – (WOT=Wide Open Throttle) This 16 position (0-F) dial is used to adjust the airflow signal during heavy acceleration conditions.
AUX - This 16 position (0-F) dial is used to adjust the airflow signal during heavy acceleration conditions when the purple TRIGGER wire is activated. This mode is active above 8 psi boost (approximate)
(The AUX dial is also used for selecting the base settings)

1) Set the Mode switch to the ones below depending on what size MAF you have:
3" MAF - Mode Switch 1 and 2 = OFF
3.5" MAF - Mode Switch 1 = ON, Mode Switch 2 = OFF.

2) Set your injector size - 510cc injectors on a 1G will be AUX = 0, and Base = 8.

3) Zero out all the other knobs. Meaning put IDLE, MID and WOT at 0. Dial Setting = 0 is 0 % flow change.
