Some are, mostly those in the hotter areas of the country it seems. My Fuel trims were not as out of wack until the temps rise. They are within 2% of zero until the IAT1 rises above 100 or so. It gets really hot in the engine compartment and some of that heat soaks into the sensor. It is normal for fuel trims to vary a few percent depending on the temps but if the IAT is reading higher than normal the ECM will respond by pulling more and more fuel as the temps rise ( more risk of detonation and less avaliable O2 to burn) the only way honestly to get correct IAT1 reading is to relocate the MAF which has the IAT sensor attached to it. The LS1 and LS2 GTO guys have done that for years so the ECM wont cut fuel and spark when it gets hot outside. It works.

 

Ok, so this maybe isn't an issue with any certain brand's CAI/SRI design per se... it's more about the heatsoak of the intake/MAF itself and the design of the SRI naturally causing the MAF to be close to a high heat source.

Edit: I got a text message last night from a member that bought an Injen intake, but was going to return it for an AEM. If he doesn't report back, I'll report back on the findings, since that's the intake design with the MAF moved forward and away from the engine.

 

Ok i have a question.....
I have the dejon intake and i notice that SOMETIMES not all of the time when you get on it in first and second gear, it feels fast until it hits max boost(110kpa) then the boost jumps down to (105kpa). Is this normal.. I just put my stock intake back on and it does this some of the time as well...

 

That is normal. Does your car feel more responsive with the stock box on?

TOFU right? I saw his logs they wernt too horrible compared to Hahns intake or any SRI that I have seen logged lately. Still though I believe that AEMs design is the best thus far as long as they got the diameter of the intake tube correct it should be a real winner.

 

actually not by much, its seems to pull harder in the lower rpms with the sri and harder in the upper rpms with the stock.....

If i can sell my dejon, i will go with the CIA cold air intake!

 

Weird mine seem to be tons more responsive down low and in the midrange but goes kind flat up top without the SRI on there IDK. I have a really agressive tune though so small fluctuations make a huge difference on my car.

 

idk....so should i just put the dejon back an and see what happens??

maybe once i get tuned, maybe that will make a little difference.

 

Check the PM I sent you about tuning out negative LTFTs.

 

No, although he may be selling/returning his too. It was another guy, though I can't seem to track down his name on CSS.net here, I know what it is on another forum. He's got a black TC coupe here in the Houston area.

 

Honestly I have not yet seen any scan data on AEMs intake yet but of all those I have seen data on the Injen intake is the best so far but still not that great.

 

I'm hoping the difference on the AEM, with the MAF being moved away from the heat, will allow for less of an issue. We'll see I guess.

 

hmmm, so do you think its not a smart move to get the CAI from clear image with the MAF still in the same spot??

 

It's looking like even the stock intakes are showing some issues with MAF placement to a small degree. I'm wondering how the AEM will fare since it's got the MAF moved more towards the front of the car.

Does anybody think that maybe having metal intake piping isn't helping, as it heats things up (esp in the area around the MAF)?

I'm asking around in the LS1/2 community to see what kind of MAF issues they run into. I'll report back if I find anything helpful.

 

yeah, but with the chromex plating it's "supposed" to help with heat dissipation.... who knows ... wtf, why can't things be easy.

I have Clear Image's CAI on order, but I'm second guessing myself currently .... I didn't buy in the group buy so I can get out of the deal if I wanted too

 

The metal piping may be partly to blame but even with the stock airbox the IAT1s can get up to 140-150* because the airbox is not fully sealed into the inner bumper and the MAF and IAT sensor are located in the hot engine bay. It does have holes drilled into the bottom of it to let water drain out.

I might be ordering AEM's intake soon to test it out.

 

I wonder what we'd find if we "sealed" the cold air snoot in the fender by blocking off the opening around the snoot going into the fender.

 

If you were able to seal that and move the MAF into the inner bumper away from the engine heat it would make a big difference in the summer time.

 

I'm going to remove my fog light for a TRUE cold air intake!!

 

More power to you as long as the weather is fair you will be fine. I have part of the lower wheel well fascia removed to help with cold air flow into the bumper.

 

yeah, in the summer time it would be beneficial for me, but we get too much rain here in PA. I was thinking some of the fascia as well .... interesting you brought that up.

 

It's funny... I thought about that too yesterday.

But then I was like... neeh

 

too much work man!! especially if it rains sporadically like it does here in PA!

 

Rains almost every afternoon here in Florida.

 

If you want to do it right, remove the headlight and have the filter poking out of the opening

 

I know you used to have SRI, but aren't you concerned with rain, etc. and having a CAI being that it rains so much in florida/?

I just picked up on the innuendo!
