Mitsubishi MAF's

[BlackMount]

So, prancing around the junkyard I see in a lot of mid to late 90's Mitsubishi's that they all share what looks like the same MAF

What would happen if I tried using a MAF out of a 7th Gen 4g64 Galant or N\T 3000GT as appose to the 2G Turbo MAF on say my 1G Turbo?? They look basically the same and I think have the same amount of pins as well..

Feed back please...

While they look the same what they flow isn't.

The 2G MAF is a 609, the 3G version you want is a 482 and the EVO MAF a 399.

All will require some sort of correction to use either via a SAFC, EPROM Chip or DSMLink to use.

yep you can take honey comb out of your stock one but a lot of people would urge you not to since your maf wont be able to read as well just spend the money like me to do it right with ither a 2 g or evo as stated above

Ok, I was just wondering because there are so many in junkyards. Thanks guys

Are the numbers the amount of air the maf can see?

 

[steve]

No they are the numbers on the top of the MAF.

idk about the 3G or the EVo Maf but I've seen quite a few people run 2G MAF with out any sort of tuner. just up'd the injectors.


I would be getting a Wideband at least if and when I do 2G MAF

 

[steve]

Some people don't care how well that their car is tuned and run a 2G MAF with 550cc injectors.
It will run, but it's not right.

Steve, could you please elaborate more on what you said about running a 2g MAF and 550's. That is the setup that i bought my car with. That plus a re-wired walborado, and no FPR.

I run a standalone now, but the car has been running kind of crappy and i think i might have some engine damage. (It did have lots of air leaks, so that could've had something to do with that also)

 

[steve]

There are plenty of posts on the site explaining the issue. Simply put the difference between a 1G and 2G MAF isn't a constant value and there is more to injectors than just the difference in rated flow.

Let not even think about starting yet another discussion on fuel pressure overrun.

 

[BlackMount]

I think Fuel Pressure over run has been suggest as much as Boost leak on this site so I would search that down man!

 

[YZFR1]

Fuel pressure over run it is.. thank you

Sorry to bring an old thread up, i am running a maf off a 96-98 galant, it has the 609 on it, is this correct ?
I ask cause my car is having a rich issue and wonder if maybe i had the wrong maf in it.

 

[steve]

I think the answer is in post 2.

 

[Dsmj89]

So then i have the right maf..
But about the flow part, i compared the maf i took off the galant and a 2g one and they both have the exact same honeycombs and all, how will it flow less ?

 

[steve]

I don't understand your question. A 609 MAF is a 609 MAF regardless of this car it came out of.

I have nothing to contribute to this thread. But I wanted to say, OP, do you have an E30 or are you just a fan? I am a fellow E30 and dsm owner!
