[RESOLVED] 1G Non Turbo MAF Upgrade can it be done???

[dallu22]

Okay so I've looked all over the forums, and I know you can upgrade a 1G Turbo Maf to a 2G Maf.... But that helps me none..I built a 12:1 compression Non turbo motor using all forged internals the whole works but.... I need to figure out how to upgrade my Maf to a 2G or a GM Translator....something anything to get more airflow, Any Ideas, Links, or anyone know of a way to fix this? and yes ive done all the hacking to the stock Aircan that can be done

When you wire it in, one wire will be missing. You will find that out once you go to rewire it.

If you want to drop some cash, you could grab ECULink and a GM MAF. Other then that I belive you still need some sort of tuning device to go with your MAF swap. I know on a 1g if you go to a 2g MAF it's recommended to go to 550cc injectors and some sort of tuning. Of course everything I look at is for turboed cars.

 

[VETTE_50_TH]

Yea, didnt even think about that when i posted. You could get some better cams. Really, your options are limited with what you are trying to do.

Thanks alot guys, i know my options are limited but i really wanna be the first person to build just an absolute monster non turbo..I've seen the article on VFAQ before about this but wasnt sure if the missing wire would affect the Translator or the 2G maf, and as for a tuning setup I picked up DSMLink a few months back from a friend who sold his 1G../as for the cams, im running some of the older Evo cams, i want to say evo 3 or 4, but i wasnt the one who found the cams for my motor, me and a friend share equal R&D on this car

.....had it tuned once and dynod and was pushing 230hp, that was with stock cams and cam gears, and stock fuel setup(except for the 450cc injectors off a turbo car) Since then I have upgraded the entire fuel system with a walboro 255 all steel braided lines a stock fuel rail thats had a few thousandths taking out of it and honed, the evo cams and a set of aem cam gears, and picked up a NOS sniper kit to drop on top on the forged internals........but the fact i havent been able to upgrade the Airflow anymore has really been bugging me and i know if i want to make anymore power im going to have to drop the cash on doing so, just havent seen a way to splice into the GM translator or for a 2G Maf for a Non turbo

again Thanks for the help and if come up with any ideas drop em on here

::EDIT:: Had a thought after posting this....the 2G Maf swap the 2G maf comes from a turbo car also......so if i found a non turbo 2g maf would that solve the missing wire issue, i would imagine the 2g mafs are just like the 1g and differ from Non Turbo to Turbo

I too have searched for this, and can't seem to find anything

 

[MathixPerforman]

I just got a hold of a conquest maf sensor that I'm going to do an experiment with. I will let you know how it turns out. If it works I'm sure it will help your problem.

3g maf

 

[MathixPerforman]

The 3g still has to be wired up similar to the 2g and for a non-turbo there is still that extra wire.

You truthfully are not gonna max out the MAF anytime soon. N/A cars run leaner, and use less air to make the same amount of power than forced induction cars. By the way the evo cams(the ones you specified) are the same as our cams, and being N/T your originals are better cams. I would get cam regrinds that are specified for N/A applications. I would look into a smim, because if your still using the stock IM then there is a big choke in it.

 

[Sp1kE]

it goes to pin 6 on a turbo car.
Pin 6 on the non turbo ecu is not even used.
If hes still using the non turbo ecu, I don't see a need for the wire to even be hooked up?

 

[dallu22]

Thanks for all the input guys, Yea the evo cams are the same my friend that i said found them works in a machine shop and did some work to them and my head. I found a 2G Non Turbo MAF today while junkyard diving fun stuff, Im gonna try and wire it up soon and my Intake manifolds a Dejon tool manifold and my throttle body has some work done to it, and JEFFREYCASTGSX you dont think I will max out the MAF on the N/A anytime soon? I really hope thats the case, it would take a massive load off my shoulders

 

[rush2252]

the 2g NA's do not run a MAF to answer your previous question.

 

[dallu22]

I found a 96 N/T Talon in the junkyard that had a MAF on it today anyhow pulled it off and gonna see if i can hook it up....couldnt really pass on taking it for 20$

There was a 4g63 n/t car built for europe. Those are rare. And I wonder why it's in an american JY...

The stock turbo maf can go to 30ish lb/min or more accurately to about 2100hz before it drops counts. I'm going to be runnign a high cr 2.4 na build in my 91 n/t car and with 272 regrinds. See my build blog. I'm fairly certian the maf won't be an issues. It's not about flow. it's about metering. And the 1g maf can't METER after 2100hz volume flow very well. I doubt we will be in that range no matter the horsepower output. We still need to be able to shift our trannies

As well the brake specific fuel consumption (BSFC) for a nonturbo motor is litarally almost half of a turbo motor. This means the fuel goes almost twice as far. We dont' have a HUGE pumping loss and basically another motor to power: the turbo. Turbos do not take wasted power, they are not free energy harnessers. So in our case the stock 240s would go about twice as far as it would if they were used on a boosted motor. IOW, since BSFC is half as much, they are like 450s to us (240cc X 2). As wll, we operate at 47psi base and not 43psi

The real way to gain some FLOW is to ditch the maf and run sd. We have megasquirt, aem, old dsmap, jackel, dsmlink, tunerpro. . . But how much volume do these motors really displace to see a significant pressure drop after the maf. If you have a turbo then you have that displacing more air and I can see the relm of the limit of the 1g maf metering to also be where it starts to cause a significant pressure drop. But we can't displace that much volume with out revving to 10K or putting on an additional air pump (turbo/supercharger).

Quit sounding so smart. I had to reread that a couple times haha.

 

[dallu22]

wow im pretty sure that just answered all my questions thanks dsm-onster i think ill go ahead and mark the thread as solved
