3G or EVO MAS wiring


Pin 1 = +5 volts
Pin 2 = Barometer
Pin 3 = Airflow Hz
Pin 4 = +12 Volts from MPI
Pin 5 = Ground
Pin 6 = Intake Air Temp
Pin 7 = Reset

So, the correct crossover wiring to our MAS plug is:
3G/EVO Pin 1 to 1G MAS Pin 4
3G/EVO Pin 2 to 1G MAS Pin 7
3G/EVO Pin 3 to 1G MAS Pin 2
3G/EVO Pin 4 to 1G MAS Pin 3
3G/EVO Pin 5 to 1G MAS Pin 6
3G/EVO Pin 6 to 1G MAS Pin 8
3G/EVO Pin 7 to 1G MAS Pin 1

The GOOD 3G MAS to find is the #482, from the Variable-Induction V-6. It flows about 99% of what an EVO MAS does.
I cut up the base to our stock aircan, and mounted the 3G MAS inside, so it looks like stock! Pictures to follow.

Re: 3G or EVO MAS wiring

I think this may have been discussed before, but what is required to compensate for the 3G MAS? Do you need a chip, or is it basically the same output as a 2G MAS?

Re: 3G or EVO MAS wiring

I cut the front mounting ring off my old GVR-4 MAS, and JBWelded it to the 3G MAS:

I had to move the connector cutout about 1/4", due to interference with the 3G MAS. I JBWelded a piece of sheetmetal underneath the aircan, and another piece fitted to the hole, to bring it up flush. I also had to then drill new holes, and tap them:

I also had to JBWeld the connector gasket unto the connector, as there was no longer any way to attach it inside the aircan:

Here's the finished MAS, almost ready to put on the car:

I had hoped that this EVO K&N setup would all fit inside the aircan, but it was 1/8" -1/4" too long. With some work, or a slightly different filter assembly, I think it would fit. However, since my REAL intention was to use the 1G K&N I already had, I didn't try to make it fit:

To use the 1G K&N, I ended having to hack all 4 mounting corners off the 3G MAS, and also remove the plastic shroud that surrounds the 7-pin connector, to allow the filter to slide on easily. The only 2 bad things I ran into:
1) there isn't any place for my BCS return vacuum line, so I have a small vacuum leak at the moment
2) the step inside the aircan doesn't allow you to use a 3G connector, so I just soldered all 7 wires directly unto the pins, and shrinkwrapped them. I'll try to put a couple more pictures up (tomorrow when the rain stops)of the finished installation. It looks TOTALLY stock!
With my new 3G MAS correction code, #880 started right up, idled perfect, and runs wonderfully. I can actually feel the difference in power, just from removing the restriction the stock MAS causes.
I know other guys have used 3G MAS's, and have some issues, but I think most of the problems stem from the fact that this MAS flows 25% more air for the same Karman Hz as a 2G, and 67% more than a 1G, so you have to add a LOT of air on an AFC.

Re: 3G or EVO MAS wiring

The #482 V-6 MAS flows so close to an EVO MAS that the 2 could be interchanged, and no one would probably notice. The graphs I've drawn show them less than 1% different, as far as Hz per liter of air intake, airflow capacity, and air pressure drop.
I'm trying to get ahold of an EVO MAS, so that I can test it 100%. But, if you look at the #482 MAS, you will see that the entire 3" inlet is unobstructed, unlike the more common #501 MAS and others that have the airhorn covering part of the inlet.

I can't say, as I don't know all the specs on a GM 3" MAF, but I doubt it is quite as good. I'd say this MAS has got to be good to at least 400HP, like the 2G, but the GM MAF is made for MUCH higher HP applications. But, its not nearly plug-and-play, and then you have all the tuning hassles. I'd say that if your HP goals are 400HP or less, this MAS would be a better choice.

Quote:

Its gotta be better! According to the spec sheets, the #482 MAS and EVO MAS have <.5 psi of pressure drop at 240 liters of air per second, whereas the 2G is listed as a maximum of almost 1 psi at the same airflow. The 3G/EVO MAS flow 25% more air for the same Karman Hz, as I said, so they are not directly interchangeable. But, the 3G/EVO has the EXTRA advantage of having a ROUND outlet, making it MUCH easier to work with than a 2G. I can DEFINITELY FEEL the difference in #880, although its 99% stock.

And, yes John, thank you VERY much for the little present. As you can see, its going to good use. In the long run, it may not be what #880 ends up with, but it gives me the ability to test and tune it so others can benefit too. I plan to do the same thing with a 3" GM MAF, so I can swap it in too for testing.

Re: 3G or EVO MAS wiring

" this MAS flows 25% more air for the same Karman Hz as a 2G, and 67% more than a 1G, so you have to add a LOT of air on an AFC. "

Jeff base on you info 2G MAS flow 29% more than stock 1G...so 67%(1g) - 25%(2g) = 42% different...but why 1G to 2G only 29%...is there a way to calculate this...

1. 1G to 2G = 29% ,so if I change the to 2G MAS, can I just add 29% on the safc for all RPM point from stock setting? (MY ECU are JDM dual board so can't logging..need to go wideband dyno for actual setting confirmation, so i need the base setting first before going for dyno..so far changing from 1G MAS to 2G MAS i can feel it pull a bit harder than before)

2. some of 2G come from stock with screw flush out and some are in..like mine i got stock evo3 (2G mas) with screw flush out...it's it still 29% different

3. 3G MAS / Evo MAS flow that you are calculate base on screw in or out?

Re: 3G or EVO MAS wiring

I also have another question - since this MAS has round exit could it be installed right before throttle body elbow (i.e. after turbo) like the others do in GMAF setup? If that's feasible then my vent-to-atmosphere BOV won't give me wrong airflow figure after letting go some calculated air (don't blame my setup, I know I shouldn't be doing this

Yes, thats a good place to start, except at idle/low airflow. This should help:
http://www.dsmchips.com/~keydiver/MAS_CORRECTION_1G_2G_3G.xls
It shows the correction that is in the ECU for the different MAS's, compared to each other.

I wouldn't touch the screw. That is a factory calibration, to make the MAS flow to match the curves in the ECU. If you turn the screw out further, you will have to add more airflow on the AFC.

Well, no, but it's also based on a different measurement principle, "hot-wire", which lends itself better to blow-through applications. Not to mention the GM MAF's are shaped/sized in a way that works easily (round, adapts to IC pipes easily).

One spec I CAN compare from the data I have is the pressure drop:
about .5 psi MAX for the 3G
almost 1 psi for the 2G. But, this is the MAXIMUM manufacturing spec, so there is nothing saying they all lose that much.
Another spec to compare is the maximum airflow they are made to count:
2G = 2700 Hz MAX at .1153 Hz per liter = 311 liters per second
3G = 2200 Hz MAX at .1478 Hz per liter = 325 liters per second
When you compare this to the anemic 1G MAS with .090 liter per Hz and a 2000 Hz safe cap, thats only 180 lps!
As you said, I think looks must be deceiving, because the 2G MAS appears larger in cross-sectional flow.
Also, if you look at the graph I posted, the 3G is much more linear at the lower airflows, again indicating that it is a more refined MAS perhaps.
This MAS was designed to be used on some big V-6's, like the 3.5l Montero Sport, or the Eclipse GTS model I believe.

They seem to be rather expensive. Not too many EVO guys are getting rid of them, and all the junkyards on car-part.com seem to want ~$200 for them. Thats why the #482 is such a good deal, they are more like $50-$75, and the performance is practically as good.
By the way, if you are scrounging for a #482, the full part number is like MD336482, IIRC, and the other number, the one you will see on car-part.com most often, is E5T08071.

Also, acording to CAPS, some Eclipse 3.0 liters, starting in 2002, had it, I believe it was a GT-S model.
Also, they used it in SOME 3.5 liter Montero Long Wagons, the V75W, and ALL Montero 3.8 liter Long Wagons, V77W. We're talking an engine with almost TWICE our cc's!

I am looking forward to having this tested setup in my car.

Here are a few pics. I will try and take a complete, before, during, and after set of pics. I have been looking to do this for a year now. I just did not want to use a 2g setup or go through the headache of a GM setup.

Re: 3G or EVO MAS wiring

I believe that air filter was from eBay, but I don't remember exactly. Like Tom said, any 2G air filter will fit the 3G MAS.
The Hz output of the 3G is almost 40% lower for the same airflow as a 1G MAS, so what I do to the chip to correct for the 3G MAS is threefold:
1) I change the MAS compensation map so that the injectors use the proper pw for the airflow coming in
2) I change the multiplier used to determine which timing and A/F map to use
3) I change the Hz at which the ECU decides which fueltrim to update
These three things together should make the 3G MAS function perfectly, I know it sure feels good in #880.

The air filter stuff was sitting on my door step this afternoon (Friday), and it came from CA in 4 days using UPS ground.

When ordering the injectors from DSMparts, I asked if they had them in stock and they said YES. I told them I needed them on Friday. They told me to pay the extra fee for 3 day select so they would be here. So I did. Well, guess what. They are not here. I called at 5:00pm today (as soon as I got home) and they said they can't get me any shipping info because they are just an ordering parts line. They said that they can't get me any info until Monday morning. This is bullshit. By Tuesday morning (Feb 1st 1:30am) I received 2 e-mails from them confirming the order, and approving the payment. Very bad customer support.

I will never buy parts from DSMparts again.

My first reply was "So, your sales staff lied to me about them being in stock just to make the sale!" They stumbled a bit.

Then I asked for a tracking number. They put me on hold for 10 minutes (on my cell phone) and then came back and said that they will now be coming from their "Midwest" warehouse. Again, I asked for a tracking number. They said that they don't get tracking numbers from that warehouse. So I asked "where is your "Midwest" warehouse?" They just said "The Midwest". I asked 3 times and their answer was still the same. "The Midwest". What tools!!!

I got home and signed into there site and clicked on there order status tab and got the info about being Fedexed from RC Eng.

I will call RC Eng tomorrow and see if they have a shipment being drop-shipped directly.

Re: 3G or EVO MAS wiring

Hacking the MAS is not as much about increasing flow, as it is about hiding flow from the ECU in order to avoid fuel cut. With a keydiver chip eliminating fuel cut and compensating for the different MAS, I don't think hacking the MAS is necessary, or even a good idea.

Re: 3G or EVO MAS wiring

I doubt it, but all bets are off when you start "hacking". Why don't you test it and get back to us?

Re: 3G or EVO MAS wiring

Any thoughts on this MAF's compatability with DSMLink (ie no Keydiver chip to compensate)?

Re: 3G or EVO MAS wiring

Just choose the compensation closest, like the 2G MAS in DSMLink, and then move the sliders up to add to the airflow, as per the graph I posted. I've talked to Tom Dorris, and that is how he is going to suggest people deal with it. Thats the same way you deal now with a hacked MAS in DSMLink, and it works rather well.

Re: 3G or EVO MAS wiring

My friend in his 91 AWD Talon Has it done to his 2G. He found how to do it on roadrace engineering.com
and it works fine for him. All it does is lean out the fuel if you are running rich. I'm going to put the mas in not hacked and then Hack it to see what the differences are.

Re: 3G or EVO MAS wiring

For those that are converting to a 3G MAS, here is the wiring/color code to help make it easy. If you have already upgraded to a 2G Mas then it is pin to pin.

Re: 3G or EVO MAS wiring

is the 3g color/pin the same as the evo 8 ?

Re: 3G or EVO MAS wiring

is a 3g mas adaptable to a dejon intake with a 2g mas on it?

Re: 3G or EVO MAS wiring

Is the dejon round at the end, or the oval shape to match the 2g maf? The 3g is round. If you have used a fernco coupling or some other method like I originally had to adapt the oval to a round dejon pipe, it could work. The 3g is basically the same size as stock VR4 mas, about 3 1/8".

Re: 3G or EVO MAS wiring

Thanks to Iceman and Keydiver, I am getting ready to install my 3G MAS. Since the wiring is so easy, I just potted up an adapter, 2G to 3G today. Here are a couple of pictures. Once the potting has set up I will make a more permanent black cover.

Re: 3G or EVO MAS wiring

Looks good. You should find the parts and build them for people.

I don't need one, but I almost did. I'm gonna go with the MAFT and GM MAF.

Re: 3G or EVO MAS wiring

For reference, the Evo VIII 3G MAS is #399.

Re: 3G or EVO MAS wiring

i have a 2g mas on my 1g now...my buddy just put an EMS in his evo and im looking into wiring up his evo mas to see the difference. his is a number 399 tho, i dunno what that exactly means but im assuming its the same as a 3g other than the 1% better flow.

Re: 3G or EVO MAS wiring

Bringing up this old thread to add one piece of information I had overlooked previously:
The documentation I have on the 2G #609 MAS indicates a pressure drop across the MAS of .92 psi at 240 liters/second of airflow. The spec on the #482 MAS is only .54 psi at 240 liters/second! That's probably good for 3-4 HP right there!
The EVO8/9 MAS is only rated at .526 psi pressure drop at 240 liters/second, in case you were curious. More good reasons to choose a #482 3G or EVO MAS over a 2G MAS.
Also, just to repost since it comes up fairly often, the #501 MAS is NOT as good as the #482 or EVO #399 MAS. It is only rated by Mitsu for 210 liters/second, and has ~.78 psi pressure drop because of the larger airhorn blocking the inlet.
I am now stocking complete packages of the good #482 MAS with the 1G-to-3G harness adapter:
#482 MAS package


Quoting 1uGlyGalaNt:

Are they good for more power than a 2g mas?
