And the Build Begins!!

[neox.286]

get the megasquirt, way more bang for your buck
I havent heard of many people running the aem on our cars though....might be interesting to see how that turns out

 

[sandspeed]

AEM is good, comes with everything you need. What about Haltech or Microtech?
For now I would just turn down the boost a little bit so as to not damage the engine.

 

[ForceFed]

Wow....256 out of that setup...I cant wait to get my motor in and tuned....If I get 275 I will be tickled to death.
I don't want soo much damn power everything breaks all the time.

Fixing isn't fun...Driving is. (yes)

First thing I was thinkin was standalone, but FCD should work too.
What was injector duty at, are they stock? Did they have a good OBD reader to see what the ecu was doing?

post some vids of the sound

Were you tuned at "The Shop"? Also- you cannot run an fcd w/ the SS. Try putting the maf in the stock position. From my experience- boosting our maf w/ a ss doesn't work very well. Your fuel cut will only get worse as ambient temps go down in the fall.

what about the afc- ftc one?

I might be missing this.... but kind of Piggyback are you using? Is it just a Apexi AFC? And you took out your MAF?

Cause you should have your MAF and just clamp it when the signal gets to about 4.8v, and then tune by boost reference. This might be your low end hesitation.

I am running a E-manage and this seemed to work for me, and I am planning to run 20psi+ on a GT2871r. I have been on the E-manage forums and they set me up.

OH nvrmind. I noticed that ur running a Split Second AFC. Not really familar with that unit, but from what I just found on the web, its kinda like the E-manage. I would let the MAF control all of what it can and just clamp at high boost.

Not sure what duty cycle i'm at but the 565 cc injectors should put me around 300 whp no prob. I Have 820 Helix injectors waiting in the wings though. I'm buying a the HKS ssq bov this week so i may move my MAF back to the stock position and see what happens. if things dont get better after that i'm getting the aem.

I did get tuned at the "the shop" in CT. theshopct.com is the site. JR tuned my car and he loves the AEM. He knows it inside and out and said he could get me a deal on it so i think im gonna contact him in a couple weeks.

It would make sense though if i'm peggin out the MAF. over 16 PSI the maf is probably getting pegged out after that. There is a slight dip in my powerband that he couldnt fix because the SS AFC only tunes by 500 rpms. Which leads to my next reason for getting the AEM. IMO the ss afc is not worth the price if the state inspections dont prevent you from getting a standalone. To many quirks.

PS. i did think about the haltech or microtech but i want JR to tune the car and he highly recomends the AEM if possible.

I know that MAM used AEM with there builds and they definitely spoke for themselves. Need we find the 12 second P5 with full stock interior at 18psi? I have never used AEM but have only heard great things.

 

[kz9]

Duty on 525's are not even going to be close to 90% at 16psi.

So I take it there is no clamp on the MAF output so yes you are going to be close to max on the stock MAF.

As for the 500rpm maps, yes they can be a bitach to tune, but my afr's stay nice and flat even with the s*** turbo i used to run, and I tune using 500 rpm maps.

 

[lowr3y]

so what kinda options do we have for a replacement MAF sensor? do they make big maf kits for us?

 

[2.0t03speed]

mpi nick will make you a 80mm maf for i think it was 350 bucks.

+1 yashooa has one and that thing is beautiful. I drool over it like all the time.

What is this clamp you speak of?

My afr's are pretty dam good but there is that one little dip in the powerband that couldnt be corrected. Which isnt that much of a concern at the momement. I want to fix this breakup after 16 psi.

Car is still pretty ballsy and feels faster then my old 05 mustang gt that had a tune intake , exahust, and 4.10s.

Working on getting the video up tonight. my friends camera is kind of ancient so it will take some fanagling. I will scan the dyno sheet tomorrow. i forgot to bring it to work today.

Dude, I would love to be running 16 psi!

I have an AEM piggyback, not a standalone.

16 Feels good...20 is giong to feel even better :0)

Hows the AEM work btw? you like it?

Bump for my clamp question.

 

[kz9]

Well the E-manage has an MAF signal interupter that allows the user to use the stock MAF and clamp the volts under or at 5v. The problem with or MAF is that it is too small for high boost applications, Thus hitting 5v (max output) an then can't calculate the fuel requirements.

So you can set the signal clamp to clamp at a determined point (best just under 5v on the stock MAF signal) This then allows the user to access an sub-injection map that can be tuned via boost reference using a Greddy Boost sensor. Hence the car still runs like stock under low to no boost because the stock MAF is doing the fuel calculations, and then when on high boost the Greddy boost sensor acts like a MAP sensor and then you can tune that way.

Most people don't like the E-manage cause they feel it can't handle high power, but really the only draw back I see is the 500rpm tuning maps.

Interesting...i think i may look into that 80mm MAF for now. It probably won't be till after summer time till i could get the standalone.
