i have nothing but good things to say about the GM translator. Sounds like either BS without actual experience, or an isolated event.

Damn, 95tsi505, I saw a car here in the bay that was 100% identical to the one in your sig! Crazy stuff....

Maybe my Twin???I need to get over there,you all gotta dope scene over there

Yeah... I was originally going to go with a GT-12, but that would require me to go all out with everything under the sun before I could get the most out of it. So I'm probobly going to go with an Evo III 16g from Slowboy. It'll tide me over until I've built the car up enough to bolt on that GT-12. Definitly going to get the MAF and Translator though.

G50.. enough youll ever need for the street..

 

[AlecW81]

Well the reason I plan on going with the GT-12 is because the Talon is only going to be my daily driver for a little while. I've got huge plans for it down the road...

So you can run it on stock injector/fuel pump with no AFC or what not. I was thinking cuz it's seeing more air flow that the car would need to compensate for it. If it can't compensate it, then you'd run lean?

Yes you can run it on stock injectors/fuel system. The translator has afc style functions just not as specific so for some people they might want an afc also just so they can fine tune with it. As for the airflow you won't be flowing more air just becuase you have the gm maf on the car but you will be able to flow more air later if you need to i.e.- more boost more efficiently and it can flow more air than a stock mas can. But when you do start turning up the boost the translator will be able to tirck the ecu in "seeing" less air being flown throught the intake tract.

91TSI505, you know what would be cool? If you painted your whole interior yellow.


The GM MAF will cause you to flow more air, because it is less restrictive than the stock MAF. However, it meters the air to the same calibration as the stock MAF, so you won't run lean as long as your fuel system can keep up.

It is...those are old pics

Kind of a question off to the side but would the GM MAF unit be pointless on a FP Big28? I know its not the biggest turbo but will it help with spool as well and I know the tuning capabilitys are good.

 

[A. Van]

If your fuel system can't keep up, thats leaning out.

OK for the people who have put this in already. I have just got mine and am putting it in today.

The white wire that is for the tach signal. Is there anywhere under the hood to get this signal from? Do I need to run it in the car to the computer? This is on a 95 model GST. Also, where do you tap the blueish wire into?

I see it says that I can use the computer for the signal or power transistor pin 4? is this under the hood? Where is this located at?

Thanks

 

[nine5raptor]

use the wire on the cas plug. under the throttle body, you will see a black/brown plug with 4 wires I believe. vampire tap or otherwise tap the white w/ blue tracer wire.

if by bluish wire, you mean the purple one, then that is for the aux. if you are running nitrous/water injection/propane.

hey guys im on the same problem and i have a few ? about the gm maft, my first ? is will i get the most out of my turbo with the gm maft and a safcII, or should i go with a dsm link and gm maft, if i dont have to spend the money for a dsm link andget the same power out of a gm maft and safcIi i wont, my second ? is where is the best place to run the gm maft, ive seen people run it on the uicp between there t/b and bov and some on the intake pipe it self. My third ? is how could u tune with this thing i mean isnt it just plugs and wires or is there an acutall tuning screw like on a bov, and is it plug and play.

 

[nine5raptor]

1. start w/ just the maft and maybe an afpr
2. you can run it either with the same performance potential
3. it has switches and knobs to tune
4. pretty much.

 

[klipzedgsx]

well i have a safcII now with my agp kit and i like it but i have to vent, and i will for sure when i get my tial bov, so i need the gm maft, but would i be able to just put this thing on or how do u tune it, also whats a better spot to put it on the uicp or the intake pipe, ive been told to put it on the uicp so i could vent. Also somone told me i wouldnt even need a intake pipe and filter if i run it from the uicp what is the advantage of that

 

[nine5raptor]

to vent, it must be after the bov.

you could tune with either the afc or the maft. the afc is rpm based (along with tps), whereas the maft is load based, which makes more sense imo.

running w/o an intake and filter is pretty dumb. little to no gains (most likely losses from the turbulent/hot post radiator air) and a very good way to ruin a turbo (just think what would happen if a rock were to be kicked up or a large bug went through the radiator as your were at full boost).

 

[klipzedgsx]

ya true well the whole intake thing i wasnt worring about i wasnt going to do it anways but how do u actually tune the maft, i know the afcII tunes the fuel levels at the rpms but is it hard to tune with both

 

[badboyr66]

I have a MAFT..and the only reason i got it was to i can have a atmospheric discharge Blitz blow off valve. And the fact of the matter is..it has really helpd my car..i have a 16g with stock 450s for now. only problem i have had is that i now need bigger injectors. I have also gotten my PDA and am waiting on a new computer to load the logging software. For the most part ...all my tuning has been done with a SDS fuel ratio meter. and a boost guage..hittin 15 psi for now , cause at 16 the injectors max out and the car fumbles and farts.

The intercooler piping I got from dejon tool made a real difference..i felt it. I was really happy with my MAFT setup and this it was well worth the cash..plus it is good knowing when i do get bigger injectors..all i have to do is twist that little knob to make em work right.

as far as the GM MAF...i got it off a totaled US forest truck that was headed for the crusher 4.3 liter V6 MAF is the same part number used on the Impalla SS with the LT1

 

[98eclipseRS]

the maft has dial knobs on it. YOu can lean out or richen your fuel mixture by turning them in either direction. You will be able to tune your car decently with just the maft and a datalogger. If you really want to fine tune your car for like dyno numbers or whatnot then you will have to get some other sort of fuel control that is more precise. So if you really feel it necassary to have both the maft and safc then you would just tune globaly on the maft and then tune is very specificaly on the safc(that way there is less adjustments to do with the safc). Where you place the maf is all up to you. Do you want to do draw through or blow through. As stated before blow through allows you to vent and it also gives you quicker spoll because there is less restriction that the air being sucked in has on it. I have the parts comming soon so i will keep you updated as to how it all turns out(oh man i can't wait!!)

 

[klipzedgsx]

well how about with my 660 injectors, and walbro 255 hp fp could i tune with just the mas with them

 

[nine5raptor]

with the maft, you mean?

yeah should work just fine.

 

[klipzedgsx]

ya i ment the maft sorry, wow i like the idea of being able to just tune the fuel with the maft and just a knob. but what is this blow through thing i hear about does that me u put it on the uicp between the bov and t/b, because thats what i want to do. also ur telling me there is no point for my afcII once i get the gm maft sense that will control my 660 injectors and the flow of my walbro 255 fp. and if i do keep the afc what setting would i leave the maft at all they way open for the most air and then tune the fuel richer or what. sorry guys ive never looked into this maft thing
