What kind of tune are we talking about? Where would I go for one? How much might it cost?

Short translation of CARB's requirements for aftermarket parts:

Cannot harm the car or cause more emissions or reduced fuel economy.

So long as it was on the stock tune and they deliberately never let the engine speed drop, a bad intake will pass CARB requirements with flying colors.

I looked through most of this thread but could not find the info. Is the airsensor on my 2011 2.5i going to have problems with my cosmo cai or not? it seems like this is only a problem for older 2.5i's.

Thanks

Your 2011 has the same parts that cause the problem with the 2005 and newer cars. However, to my knowledge, no one has yet tested a 2011 to confirm that the same parts are causing the same problem. Log it for yourself and find out.

I do not know how to log such values mentions in the OP. I was under the impression that reseting the ecu fixed it. Is there nothing i can do to fix this problem?

Fixes:

1) Run a damned hybrid intake. It's not that hard, it's just as good as a CAI/SRI, and it's the cheapest option.

2) Run a CAI/SRI just because you're stubborn and pay for a professional custom tune from a tuner that knows the trick for how to make it work. This is definitely a hack. It doesn't make the problem go away, it just slaps a band-aid on it. Also, as far as I've ever heard, only one person in the US has figured out the trick.

Default Questions

I am searching for more usable power across the full rpm range and am concerned that adding a hybrid intake provides more peak power and moves torque up in the rpm range.

1. Does installing a hybrid intake which eliminates the “torque box” reduce torque or move it upward in the rpm range?
2. What kind of gains would installing smooth tubing between the MAF and Torque box provide? Comparable to a full hybrid?

Thanks
Marc

This must be the first reasonable question since page 10!

1) There is no evidence that the so-called Torque Box actually has anything to do with torque. In fact, the one and only test that's ever been done specifically about this question showed absolutely no change in torque with or without it. Additionally, if you look at the first post, you'll see there are no regions where the hybrid load trace is substantially below the stock load trace.

2) That configuration wasn't tested because there was no point in light of #1

williaty,

Thank you for the quick response.

I suspected that this was going to be the answer but wanted to be sure.

Now to find an inexpensive pipe.

2008+ still seem to have the same problem as the older cars. Haven't tested it personally but people I trust have.

I have no idea about the 1.6L engines as they aren't even available in the US. From 2005 on, ALL the non-turbo engines sold in the US use a MAF sensor and have this problem.

Hey guys,
So I just did the hybrid intake using the autozone piping and keeping the stock airbox. I have done this before but took it off for a period of time because i had to do a lot of long distance driving. Well i put it back on today and now the cruise control light is flashing, traction control light is on, and the CEL is on. thoughts? if anyone has any ideas on what happened could you help me out?

You likely have an air leak, check everything again. Be sure you didn't tweak any electrical connectors anywhere too.
