16vtawd you notice some nice gains witht the maft/upper ic?

no it doesnt even measure air temp, the translator sends the ecu a fixed number of like 80 degrees for the air temp, it never changes. that could be a good thing or bad, but i believe they had to do that cause they may not have been able to translate the temp signal so the mitsu ecu could understand it , or may not have wanted to. i may be wrong on that, but no for sure its a fixed number. same with baromtric pressure senser is fixed to i believe.

That's true the temp number sent to the ecu is fixed but the GM MAF still measures temperature indirectly. It's extremly accurate at detecting temperature/density changes through the hot wire method of metering. The density and volume are sent to the ecu all as the same number so the ECU still knows to add or remove fuel for a change in temp/density.

Bullshit! Heh.. What else are you using to tune with?

dead serious, havent changed a thing.....well...TB seals i guess

 

[98eclipseRS]

turbodsm86: there should be another white wire commign from the translator box. YOu take that wire and tap it into the grey wire coming out of the CAS

Anyone connect a FMIC to this uicp? I have it and I'm looking into getting a fmic and some custom bends.

BTW, I love the Maft, the tuning method is simple as long as you have a logger.

Hey i have to say that i am about to make that setup with my Talon, but i have to say.......Why not just strap a filter to the turbo???? Instead of buying an intake?????, what i am doing is i have already made 4 brackets from the local home depot and 2 clamps that will allow me to add a homemade filter from K&N and just a screen with a foam layer behind it...pics will come shortly....Just something to make without buying the intake and something that will suck my air faster with less travel...and hopefully will make the turbo sound louder when spooling.......anyways, still like the setup...MAD PROPS...

I have my FMIC hooked up to the Dejon piping w/ 3" GM MAF... Works perfect.

Even though I'm a 2G... me too

 

[danielbui]

how did you guys get from MAFT to making your own filters?

As 98spydert mentioned it does measure temperature indirectly. The actual number that it is pre programmed to send to the ecu is something around 120. Since the MAF can read density along with volume rather than just volume alone like the MAS, it can account for the change in temperature accordingly.
I justy picked up a book by "MotorBooks" Called Engine Management Systems - it is really thorough and complete. It has a section discussing the different sensors. That is where I got my info from.

If you want your turbo to suck all that hot air away from the exhaust manifold, be my guest...you dont have to buy an intake pipe...its simple to make your own...i had a cold air intake laying around off my 2g and i hacked it in half and it works great...i think you could get by with just a 90* mandrel bend too

I just used the zip ties because i wanted to go test and tune the the car next time i will use red zipties for a clean look

Yea i notice quicker spoolup and more power once i got it tuned right

 

[mavisky]

Glad to see you like Dave's setup. It's probably one of the easiest to install maft piping setups out there.

Here's my custom piping setup.

One thing i did though was to extend the wiring harness so that the maft box sits inside the car with me instead of under the hood. It allows me to make changes without having to get out of the car and under the hood every time.

I just installed my gm mas blow through style, inline with my BR fmic, it is quite easy to install, it literally only takes 1/2 an hour
unfortunately I dont have pictures to post yet, and since it is 10 degrees outside I havent started tuning it yet.

 

[MC23]

I couldnt get mine to idle right.... anyone know how to fix it???

 

[miteclgst]

There could be infinite reasons why the car may not idle right. Did you make sure that your injector compensation is correct if you are using it? Is the sensor placed in the system with the divider in the verticle position? Is air flowing through the sensor as per the arrow on the unit? Is your idle adjustment knob adjusted correctly? Do you have the unit set for the correct mode?
In case you don't have the user's manual (I didn't) it explains all of this stuff in it. Here is a link to the forum on fullthrottletech.com where the file is located. http://www.fullthrottletech.com/showthread.php?t=894 Good Luck

richen the idle knob

 

[MC23]

yea i checked all that and i do have the instructions, and i did a bunch of trial and error stuff. and couldnt get it right, i put the stock stuff back on and worked fine again.

Just out of curiousity, Do you have a logger? If you do I would replace everything and see what your short and long term fuel trims are at idle. If they are really off, to the point where the computer either can't add more fuel (set too lean) or can't lean it out enough (way too rich), then you will need to check your adjustments. Did it work normally under mid and WOT conditions or was it simply an idle problem?

 

[tsibryan]

Somewhat off topic, but mavisky, can you post or PM me some info on how you moved and reattached your cruise control? I want to go blow-thru and keep the cruise. Also, how/where did you get the piping done? It looks very professional

Just out of curiousity I noticed that your MAF plug is in the 6:00 position. I thought that it said in the manual that the air divider needed to be verticle for the sensor to function correctly? This would require that the plug be either in the 3:00 or 9:00 positions. Is that just a 2G thing? Does it not make any difference?

91-94 had the cruise in a different spot than you, behind the intake

 

[tsibryan]

So that's the stock location? Hmm, it didn't look factory with the cables still running over the intake. Thanks

[deeeep]

i wanted to get a blow through set up but im all stock is there some way i can instal it and 0 it out so i dont have to tune it so i can run it with out bigger injectors
