Thoughts on Maf-t setup?

[SevensOdd]

Hey what are your thoughts on the Maf-t setup? Blow-thru. My MAS is completely DEAD and this seems like a great upgrade/replacement. A bit pricey tho...are there other paths to take? If so what how do they stack up? Thanks

I keep hearing about all these problems with the changes and problems with the MAF-T. What are they?
I ran it in two DSM's and dodge stealth since it came out and have'nt had a problem with it!!!
Is it improper install or improper tuning?
My air sensors have all been in blow through and I don't get any kind of weird readings.
Not to mention I installed on in a guys car that I was working on and that car was the easiest to install and tune.
The awd we ran the GM sensor in blow through and didn't have to make any changes to the Translator in four differant races. The temps started out at 70 degrees
the first race and ended up being 90 by the next. Isnt that a big temp change gap for the ECU to correct for?
The easiest way to go would be to get a chip burnt to your specs and let the ECU do the rest. The more control the ECU has the better.
What are you future goals for performance?

300+ short range..and 450ish long range goal. by short range i mean within a few months and long, within a few years.

I did a little research in price, to do it the easy way with the AFC/keydiver chip with 2G mas combo is a little more than the MAFT setup. If you bought from reputable vendors plus a used palm, AFC, GM sensor you can knock a few hundred dollars off your original price. If you do more research you can get it cheaper. I see it if you do the AFC the chip would ease the amount of tuning and you would have the ecu do most of the work. If you run the MAFT setup it takes more time to setup and tune. Both of these would allow you to hit your goals. The MAFT will allow you to run more that both your goals. (600+ HP) I might be missing some stuff so others chime in. Im sure there are other tuning methods but these seem to be the most popular.

Well, I run a Gen 2 trans with a 3.5" blowthrough MAF (including 3.5" piping, having a piping size transition in front of or behind the MAF is a big no no and probably the source of many problems in the DSM community). I got the Gen 2 for free from Full Throttle Speed at the Buick Nationals(Thanks FTS) On my DSM I HAVE to run a MAF sensor as my volumetric efficiency changes depending on if the secondary turbo is spooled or not. I suppose I could run two MAP sensors, but that's a pain in the rear, and most aftermarket ECU's won't handle it.

Anyway, tuning with the Gen 2, a wideband, and an ostrich couldn't be simpler. Just flash in the extended map base tune scaled to injector size, set rev, NLTS and stutter limits, and fill in the wideband AFR tracking table in the Gen 2. Since the very first time I fired the car up and drove it out of the garage with the new sequential turbo setup, I haven't had to touch a thing in the tune and it stays at a rock solid 11.8:1 at WOT. The Gen 2 grabs the wideband signal and uses it to adjust the tune.

I ran the Gen 2 on my Buick for a while and can directly compare it to the Gen 1. Everything about the Gen 2 is 10x better than the Gen 1, including drivability, cold start, tuning, ignition timing control, etc.

like i said ive never tuned before so most of that...WHOOSH..right over my head . As for a 2g mas goes, what all would i need along with the 2g mas, if i chose to go this way?

if u are willing to spend $800 to run the matf then save up a few hundred dollars more and just get aem. it is by far better then any of the methods sugested.

2g maf, 550's or 650's (not necessary if you've got a chip but still a decent time to upgrade), a pigtail to wire it in, filter and adapter, maybe a pipe, chip, safc.

That should do it. Almost all of it you can buy used for an awesome price.

 

[SevensOdd]

aem what?

 

[staticbrainwash]

AEM EMS, it's a full standalone engine management. Honestly, for 800 if you were going to go to aem i'd actually suggest dsmlink.

 

[SevensOdd]

what do you mean by adapater?

 

[staticbrainwash]

Wow, dude, not be be harsh. But honestly before you get anything to tune you have to do a TON more research on these car, and how they work and whats going on.

An adapter and a filter. The adapter lets you put a cone filter right on the 2g maf. They're about 15 bucks on ebay, and a k&n in that size is like maybe 40 bucks.

If you want to talk about "far better" let's bring megasquirt efi into this little contest. EMS is too expensive and I've heard it can be very difficult to configure... but hey, it's another "out of the box" solution.... and you're still paying someone for their research and development. Give me some money and I'll tell you how to get in that door over there.... thanks, just turn the knob and push.

Just get larger injectors and a Keydiver chip and call it a day.

I've got a MAFT and I must say, the only reason I would suggest you get one is if you're producing enough airflow that the stock system has become the limiting factor in making more power. Tuning with the MAFT is a pain. It should be noted that I haven't used the newest version of the MAFT. If you decide to go with the MAF, I seriously recommend buying DSMLink for tuning. DSMLink is one of the best bang for the buck mods you can possibly get, assuming you take the time to learn how to use it.
