The fuel trims should be consistantly positive and yes the car drives just fine the idle on mine was rough a few times on cold start up but it is better now that I have the MAF calibration 98% of the way dialed in. It pulls really hard now. A ton better than the stock airbox.

 

Do you have any lb/min #'s of stock airbox vs AEM?

 

where in the hell have you been you never post in the random talk thread lol

 

So is the aem a safe intake to buy....My dejon is sold and i need something else..it is to quiet being stock

 

I get 32-33# on the stock airbox with K&N drop in.

 

HP Tuners FTW.

NOT.

 

what does this mean and is it good? lol

 

It means I am flowing the max the turbo will push through.

 

with a K&N and stock tune?

 

Uh, NO I haven't been on the stock tune since 1400 miles!

Nah, those numbers are tuned... on the stock tune it was about 22-23 lbs/min!

 

lol i didnt know which tune you were talking about lol.

 

That was on my current tune... which is version 5-6-7 iunno I change it all the time! lol

 

Not exactly an answer to your question, but with my Injen I was seeing upwards of 34-35 lb/min, stock box was 32-33 lb/min. I believe the AEM has a larger diameter than the Injen however, so based on MAF location and the aforementioned, they could be pretty different.


Nice.

 

At least I have a properly tuned car. You paid $400 for a canned tune that adds 20 hp yay, and if you add any mods you cannot tune for them and your airloads are so low that added mods wont add much power at all anyway.

Flow is definately up with the AEM intake. I have my MAF tables 99% of the way corrected for it and I see 34 lbs /min at only 5200 rpms and that was only a 1 second pull. I think it will flow a tad more up top maybe 35-36 lbs/min. The stock turbo's max is approx 36 lbs/min.

 

Not directed towards you all, but just putting a point out there:

Well, if you think about it... anytime you make the turbo have to "suck" less hard (usually referred to as head or suction head) to get the air in before compressing it, the quicker it'll spool and more it will easily flow. Imagine trying to suck air very quickly through a very long straw and small diameter straw vs a short straw or a wider straw. This means SRIs and larger diameter CAIs are the way to go. That being said though, the MAFs got issues with SRI designs (any heat issues aside). This means that a large diameter CAI is the way to go at this time.

 

Agreed. This car runs better with positive fuel trims than it does with negative ones. What impresses me the most is that it is flowing more air now at 5200 then it used to at 6200.

 

I'm gonna meet up with a local member here and he's gonna hook up HPT and scan my car to see what it's doing. I'm going to look at some of the graphs and see what can be done with this car also. I'll have some #'s on Wed or Thurs.

 

hmmm...im thinking about ordering this intake today or tomorrow

 

LTFT should be +7 to +10 depends on the car honestly.

 

Does the +7 - +10 equate to an overly rich condition? I remember you saying that you logged someone else's car with another intake (forgot what) and it was dead on like stock.

 

Actually positive fuel trims are the ECMs response to a lean condition. Because of the larger diameter of the AEM intake the MAF sensor sees less of the incoming air molecules than it should. The O2 sensor detects that the A/F is too lean and the ECM reponds by adding more fuel until the O2 sensor sees the proper A/F mixture. The car bogs a lot less then it did with the negative fuel trims caused by Dejons intake even before I retuned the MAF. It may stumble the first time or two when you cold start it until the ECM learns the new fuel trims. After it warms up though it runs great.

 

Your definition of a "properly tuned car" is based on your opinion, which last time I checked was NOT a professional opinion....

 

You dont know me so your ideas are based on pure conjecture and bias not facts. If you read all my posts you might realize that I know what I am talking about.

 

If you've been paid to tune someone's car, you're technically a professional.

 

Ahhh understood but what I guess I was trying to ask was if the +7 - +10 was adding a lot more fuel than the stock fuel trim? I would assume that the intake would produce a lean condition as the intake is pushing a lot more air and require more fuel. Thanks for the answers
