another MAFT question, a simple one

[giterboosted]

so basically what im gathering is that if i use this unit and a gm maf sensor then im pretty much set?

is this a correct asumption, cause im not really needing to do much tuning at this point in time, im aiming for an apexi afc in the future and i dont want to spend a wad on somehting i wont nessesarily use for a long period of time

 

[GrimJack]

Yes... and no.

You are correct in that purchasing the MAFT + a GM sensor will get you running. You are incorrect IMO when you plan to run this plus an SAFC in the future for tuning - you would be better off just buying the MAFT Pro.

i understand that but as of rite now im on a tight budget but this car is my passion so im determined to still play lol
but what kind of sensor would i need a gm MAF or MAP?
and if a MAP then how do i install such an item?

im still learning how some things work , im really sorry if i ask retarded questions

id love to know also i have a maf prob and im only needing a stock turbo maf to drive the car so.

 

[williamb82]

the reg maft uses a gm maf. i used the 3in gm maf which is comparable in flow to the lex. currently have 780cc/min injectors installed with it. if your wanting to tune later, get the maft pro, you can tune the fuel AND timing with it plus it gets rid of the maf all together and goes map

 

[maitai69691]

is there a certin gm maf you have to use

 

[GrimJack]

Not really, it will work with just about any of them. The 3", 3 wire sensors are the best, just because they are easy to plug and play.

which maft are you looking at? the original or the maft gen 2? the gen 2 is a maft and much more than an afc. id get that one and be done.

here is the info on the gen 2 (note: it is NOT the maft pro). its only $60 more than the regular maft

dramatic upgrade from the regular unit. Borrowing technology from the Translator Pro, the Gen 2 now has the ability to adjust fuel + or - 60% in 1/2% steps across 14 RPM bands in 3 different load areas.

Full Throttle has also added "wideband tracking" technology to this unit. You can connect any populal wideband that has a 0-5 volt output on the controller and then you can set the desired A/F ratio across the RPM band at WOT. The Gen 2 will then track A/F and automatically adjust the fuel to keep the desired ratio. If the car leans out, the Gen 2 will add fuel and if the car runs rich it will remove fuel.

ok so if i wanted to use the entire install solution then where exactly do i put the pressure sensor? i really dont understand some of these things,

i know i get a gm pressure sensor and an intake temp sensor, do i simply plumb both of these into the intake mani??

 

[GrimJack]

If you want to go MAFT Pro, which would allow you to run MAP - Manifold Absolute Pressure + AIT - Air Intake Temperature, then you have lots of options for the sensors.

I have my AIT in the intercooler pipes just after the intercooler. I have my MAP sensor hooked up to the intake manifold, after the throttle body.

If you want to go MAFT v2 with a MAF - Mass Air Flow sensor, you can mount the MAF pretty much anywhere along the IC pipes. I suggest keeping it away from the turbo though, just because I like keeping my wiring cool.

 

[williamb82]

damn, the maft2 sounds good. cant complain though, my maft was free as i was the one that sent a stock 7mgte maf to be calibrated, when i got my maf back i also had a maft in the box. hehehe.

 

[giterboosted]

so im confused...
which is better for my application, im only wanting mild tuning seeing as how i cant really afford huge mods at this time, but id really like to vent into the atmosphere and be able to run open turbo with a bit of small tuning

so which would suit me more, the one with the AIT and the MAP?

 

[dbsupra90]

the original maft has very little tuning capabilities.

most ran the maft and an afc.

but, the new gen 2 maft does so much more than an afc does.

so, i would get the gen 2 maft and a 3" gm maf. i believe the maftpro, map sensor, etc is more than you need for your application.

 

[giterboosted]

even so, what exactly do i do with such items?
where in the system do i place them? basically i just wana know bout the MAP sensor, how i apply it

 

[dbsupra90]

there is a big difference between a map and maf sensor.

maf sensor you can put in front of the turbo in place of the afm. or, you can put it inline of any of the ic pipes. just be advised if you want the bov to work correctly, the maf has to be after the bov.

map sensor is just a small electrical box w/ a vac line going to it. it is external to the motor and will allow you to run without an afm or a maf.

if you want to run a map sensor, you will need a vpc, map ecu, or maftpro. any of these setups are quite a bit more than the maft or maft gen 2 ($500+ vs $260 and $50 or cheaper maf sensor)

ok guys just so you know im not running in circles this is the kit im talking about using

http://www.horsepowerfreaks.com/sale/HorsepowerFreaks/Electronics/MAF_Translators/part/PRO_Kit

just the basic one tho, but i can afford this with a bit of time and i feel it be better to have a lil more than i need now so that i have it in the future when i wana tune more in depth

so exactly how do i run the vaccume line to the map? just anywhere into the intake mani? or what, i mean im really wantin to get this stuf down so i can jump on it when i order it

 

[dbsupra90]

i thought you didnt want to spend much, which is why i suggested the other one.

it comes with instructions on what to do. but basically, you wire it into the ecu. thread the air intake temp sensor into the ic pipe. run a vac line off the intake manifold to the map sensor.

also, it is much easier to tune if you have a laptop pc.

 

[GrimJack]

also, it is much easier to tune if you have a laptop pc.

AND a wideband. Seriously, that Innovative LC-1 is dirt cheap, buy one!

 

[giterboosted]

you really think its worth the extra dough to use the wideband?

and how can i tune it with a pc? i can use my mac i think but does it come with software or something of the sort that i use to tune it?

 

[GrimJack]

The wideband means you can set it to essentially autotune at wide open throttle. If it needs more fuel, it sends it. It's awesome.
