When I installed my AEM intake, I expected to see a noticeable increase in torque. I was told that I need a programmer to make a diffrence with an intake. Turns out that it doesn't matter if I changed the intake cause the ecu is programmed to breathe in only so much air anyways. The programmer is used to change these settings and let the car breathe in more air at a time giving the car more torque. Has anyone tried this ? Should I just try reseting the ecu?

You can try restting the ECU. Should/Might help a little. You won't get more that a few HP and a few ft/lbs and those willl come higher (3000+ rpm) in the rev range more than likely.

I'm not sure what/how the E-Manage and similar product's work but they are the only psuedo-engine management available for the 3G TL,

The CAI's are way oversold for the amount of HP & Torque they will produce. The 3.2/3.5 engines are not really restricted by the amount of air that a stock intake will pass.

As I have been led to understand it, the stock external intake system (that which connects to the throttle body and terminates at the air intake source) is actually quite good. The only real area where any sort of restriction may exist is the resonator (sometimes referred to as the air silencer). The path to the throttle body is relatively free. Therefore adding an after-market external intake system may not reward you with much of an increase.

During the first year I owned my TL, I experimented with using a short WAI that offered a direct route to the throttle body and made use of an Apexi Power Intake dry element filter. I made some very unofficial runs using a stop watch and seat of the pants and saw no difference between the stock setup and the Apexi add on.

I do know the Apexi filter works great in the right application and with my last car, a 2002 Altima SE, I installed the Frankencar intake with the Apexi filter. This, along with a Mossy catback exhaust system made the engine car come alive. But then again, the intake for the V6 Altima was very restrictive and ridiculously made.

Oh, the exhaust on the TL appears to be far better than that which stock was on my Altima, too.

The CAI is a noise maker. Thats about it. If you take apart the resonator you will see there is no restriction. It is just a box that allows air to expand. And even if you believe the dyno charts that manufacturers publish, the gains are above 5000 RPM.

SouthernBoy

Ok, no baffles the?

If it is just an expansion chamber, that will also have a negative affect on air flow.. specifically flow velocity. The same is true with headers, the diameter of the individual tubing, and their terminating collectors. Of course, those are a non-issue with the TL since you cannot install headers on the stock heads.

I think people just need to stop thinking their car is going to be noticably faster with a CAI upgrade. Yes, they do make more power almost 100% of the time, but it's not enough to really feel with the butt dyno; maybe 6 or 7 whp and tq on these cars. But they do sound damn good imo.

All we need to do is get AEM to get off there butt, and make the V2 CIA for the 3.2 - 3.5 2006 and up!

It make more power with a deeper growel.....

I want to know if it's a good idea to send out my ecu and have it reprogrammed? Would I feel a bigger diffrence than the CAI? Has anybody tried it?

Disconnect the battery for an hour and let it idle for 15 minutes after that, if you havent already done so.I love my CAI basically for the noise, i didnt expect anything else for ~ $200.

blue.fired

No Kidding, the noise comes and you expect armageddon.It just doesnt feel that much faster than just leaving it stock.

I felt nothing from my CAI ...but it does sound good . So far, the only mod I actually felt anything from was the exhaust and maybe the A-pipe.

It's once you put everything together and end up with 20-30 hp that gains are noticable. Problem is, most people do one mod at a time, over time and don't notice much difference as opposed to doing everything at once. If you were to do intake, TB spacer, pulley, J pipe, test pipe, and cat back all in the same weekend, you'd end up saying "DAMN".

Houston

ok, I understand about the CAI. My question now is strictly about the programmer. Has anybody tried it? Is it worth it?

Lerlactl

I agree

What the heck just happened to this thread... Somehow it got hi-jacked by a grammatically bewildered spammer.

*edit* apparently the post is gone now..

I don't know of any person(s) that have made a tune for the TL availible to the public.

A few members have said they were able to get a Hondata tune from Church Auto in California and got good gains, however no one can corroborate their story and Hondata denies knowing about a TL tune.
