Question Cobbtuning Cold Air Intake

I was just cruising the www.cobbtuning.com website looking for new toys, and I stumbled across what appears to be quite the interesting "new toy" I think I need. I am one of those "I see it, I need it" guys, but I wanted to get advice/opinion before I dive into a new toy purchase.

I noticed at http://cobbtuning.com/ssi/osb2/itemdetails.cfm?ID=96
it is stated at the bottom of the page "This system was designed to be used with a properly tuned Unichip system. Installation of intake without a Unichip properly tuned on your vehicle may result in less than optimal results. Cobb Tuning, and it's network of authorized installation centers, can provide any necessary Unichip tuning when using this intake."

Can I reset my ECU and accomplish the same results, or am I missing something here?
Unichip Piggyback ECU upgrade = $650. Geesh. I am sure it's great and all, but I dunno if I "need" this.

Any input? Thanx.

Thumbs up Intercooler

Just thought I would add:

KICK @SS intercoolers though. I have a definite appreciate for Cobb Tuning. These guys are cool.

no, resetting your ecu would not do the same thing.

cobb tunings point is, and they are basically right, is that when you modify your car, there is a chance you will knock the tuning out of whack beyond the stock computers ability to adapt.

once youve done this, theres several options as far as how to get the tuning back in line. The unichip is one of them.

1. Your subaru runs rich already
2. Your ecu will attempt to learn what needs to be done to run correctly.

I have this cold air intake on the way...w/o Unichip. I'll post my results when I do...as well as A/F ratios and any other abnormallities.

Frankly...I think Cobb put that for 'protection' but it is a notable procaution.

If it doesn't work...*shrug*...its one more reason to get some kind of ECU upgrade.

this thing won't work much differently from any other cold air intake. The WRX runs rich as heck already and the engine temp stays pretty low on my gauge. I too have ordered the Cobb/APS intake and am waiting for it to come back from eternal backorder.

From what I understand, you don't really need to reset your ECU unless you want to feel the effects of the mod immediately. The ECU will learn the mod in time.

Cobb's unichip will allow your car to get alot more out of the CAI than your stock ECU will do, but you should get a hi-performance exhaust too before you get the unichip installed and tuned to your car.

Cobb isn't trying to sell you a Unichip just so you can have a Cold Air Intake... they are just pointing out that the stock ECU (no aftermarket ECU or piggyback) may not make full use of all the potential benifits given by a Cold Air Intake... This isn't just Cobb's CAI either - any Cold Air Intake will be best put to use through a tuneable setup - (uni, Tec, link, etc)...

Since were kinda on the topic of ECU's, will the uni-chip take off the govener? If not which one will?
