performance gains with Maf-t??

[kgtalon95]

OKay guys, I know that blow through allows you to vent......duh.

But what are the performance gains or drivability gains you get by going with this over say a 2g mass???

The reason I ask is that I have a 2g mass / afc combo right now in my 1g and got a gm maf for free. Would it be beneficial for me to use a translator??

Also, can this be used with a map sensor....another one of my future plans

 

[Jetblack]

You can use it to control fuel if bigger injectors are used and it modifies the airflow signal to the ecu allowing to lean or richen the car at idle low boost and hi boost levles. Just have a datalogger with it.

 

[99gst_racer]

Yeah the sensor itself it larger in diameter and much less restrictive (no honeycombs), so for people that are limited by the flow of the stock MAS, the MAFT is a great alternative. And as stated above, it allows you to do some tuning much like an SAFC.

 

[DSMTalonAWD51]

so say for example you got a set of 720's and a maf transator, would you still have the same problem with excessive timing as you get with the safc?

Running a blow through set up will also help turbo spool.

no, you would have that same problem with the MAFT too. You need to have your ecu chipped to compensate for the larger injectors. It is kind of a PITA to tune anything larger than 650's with the MAFT.

Right

You can moderatly adjust for bigger injectors but its best to get a chip for your car to compensate.

This is one of the points why I dont understand by people go with a GM unit over something like a Pro-M meter where you can do a global adjustment with just one knob and not even need a chip for your car.

 

[kgtalon95]

OKay so I guess me next question is:

Is having an afc/maf-t/chipped ecu......the next best thing to dsmlink???

Sounds like to me if you have a chipped ecu and afc, then the maf-t is only good for venting & less intake restriction??

How does a maf-t deal with weather changes compared to the normal mass?? Better/ Worse??

 

[99gst_racer]

Is having an afc/maf-t/chipped ecu......the next best thing to dsmlink???

Well, the AFC and MAFT pretty much do the same thing, so you dont really need both. DSMlink is kinda like a "SAFC/logger/chipped ECU" combo, but the link does allow for much more of an adjustment. DSMlink will obviously be better for the more serious tuner.

Sounds like to me if you have a chipped ecu and afc, then the maf-t is only good for venting & less intake restriction??

That is correct. But if you had a MAFT, then you would not need the SAFC. or vice versa.

 

[kgtalon95]

Well since I already have an afc/logger combe right now would you guys recommend I get an eprom ecu and get it chipped rather than go dsmlink??

 

[billdo_83]

That is correct. But if you had a MAFT, then you would not need the SAFC. or vice versa.

You still need an AFC if you have a MAF-T set up becuase the GM unit does not allow you to make fine tune adjustments.

People dont know about the Pro-M setup and how that works in the DSM community. It allows you to make fine tune adjustments with a laptop if you want to or else use the maf-tuner box and make adjustments by just turning 5 knobs. It also does not need to be retuned after you tune your car in becuase it adds fuel based on load rather than TPS and RPM like other devices use.

Newer versions of gm maf-t have an rpm mode fine tuning adjustable in rpm's 2% at a time. Thus they are not as coarse as the older versions, but it certainly won't answer all your tuning desires if you want to go deep into the subject.

 

[billdo_83]

Even tuning with a GM that way it is no where in the ball park compared to a car that is running a Pro-M MAF.

 

[blackGSX2g]

I've seen excellent gains in spoolup alone with switching to the GM MAF. For the ultimate setup, go with DSMLink with a MAFT setup. Gives you every tuning aspect you could ever hope for as well as the benefits of maft..

That being said, I've only got MAFT and can get full spool (15-18psi) on a stock evo III 16g at about 2600 rpms....its almost instantanious. I can almost guarantee that it will gain at least 500-800 rpms to your spoolup. Find someone that has it and is willing to swap it into your car for a few runs...its worth it.

You do gain spool with a GM over both of the stock MAS.

I'm just trying to bring a new sensor to light here. One that is new to the DSM crowd and will become popular once people start running it on their car. The GM can only go so far and can only be tuned so well.

Bottem line. unless your running 40lb/min air and running into airflow reading limitations. or want to vent the bov. gm-maft is not a good choice.

apexi's tunning devices are relitivly easy, and veary user frendly compared to the maft. its no comparision. if somone were to use dsmlink and have maft they would have to zero out the maft for everything to work correctly. and then were back to the bottem line. why do you need a maft?

i personaly would buy the maft/dsmlink combo if i had the extra $. its just impressive when you see it at your local track. makes me want to bust out the Chase Platinum card just thinking about it......

explain this to me.. i want to know how volumetric effeceny is rased to that degree where airflow is inceased enough to produce those kind of numbers by simply replacing the maf with a larger compasity mafs.. everyone i've ever talked to said they were lucky to get 200rpm increase at best.

 

[SoCalGST]

not trying to steal the thread here, but if you look at my mod list, u'll see i have pacesetter headers. now someone wants to trade me a maft with gm or whatever for my pacesetters.

i aready know about the pacesetters so dont bring that up , but would it be worth it?
and how do u run the maft? like do u just disconnect your mas or what, cuz i dont wanna have to buy a new intake or anything... please enlighten me.

 

[kgtalon95]

Will someone explain what the pro-M MAF is and why it so superior and how you tune with it??? I've never even heard of it before!!

 

[billdo_83]

The Pro-M is a MAF that the mustang guys have been using forever.

its much more accurate MAF then the GM unit and you can tune with it by using a tuner box that has 5 knobs and 10 LEDs. You tune with it by driving your car and an LED will light up. Turn the knob that is above the LED and you are tuning that load point. Once your car is tuned in at all the load points you wont need to retune your car becuase it automatically adjusts for differneces in load. IE: Turning boost up or down.

There is also a Temp sensor that takes the outside temp and compensates your tune depending on if its warmer or colder out so you dont need to retune your car for those cold nights

Its new to the DSM crowd so that is why no one has heard of it.

Warren Dzoursaw (sp?) Uses it on his GS-t, 3kGT VR4, Colt (with a 4g63 stroker and 60-1), Myself and a few other people are the only ones at the moment using it on our cars. The number of people using it on DSMs is growing as the word of this great unit gets around to this community.

 

[trbotaln]

Do you run a mustang MAF in a blow-through setup with the pro-m?

 

[kgtalon95]

Wow, that sounds like the perfect tuning device, something that tunes on load & compensates for temp changes!!!!! So when will the rest of us be able to get our hands on this thing??

 

[99gst_racer]

billdo_83 - Any links to read more about it? Where do you get it? How much does it cost?

 

[madaba]

i thought pro-m went out of business?

 

[billdo_83]

It really is the perfect tuning device in my opinion.

I got mine from SRV Performance which is a shop in my area that is just finalizing minor details before they get started which should be tonite or tommorw I've been told.


The esstentially you are using the same Maf as the Mustangs and other cars that use this setup but its just calibrated differnetly. They can calibrate this meter for any car that does not use a MAP system. So porsches, subaru, mustang, chevy you get the picture anyways.


Their site is www.srvperformance.com but now that I check it, its not up at the moment.
I was going to put a product review of it once I gave it a little more time so I know all of the quirks of the system.

Madaba - Pro-M did go out of business but the stock was bought up and the only place that I know of that is selling pro-ms directly to the public right now willl be SRV.
