Putting in CAI, will ECU self adjust?

I received my K&N CAI today. Will undertake installing it tomorrow, watching Youtube video's of the procedure today. Not very mechanically inclined but it looks easy enough. Any hints would be appreciated

Questions though: will the ECU self adjust to the change in air flow? Or is there something I need to do?

Thank you

Yes the ECU will adjust after so many miles of driving.

The instructions dont tell you to do this for whatever reason but one of the first things you want to do is remove the stock air boxes after the braces come out. This will give you way more room to disconnect the stock pipes and hoses.

Also it seems pretty common that one of the hose clamps they give you is undersized. It was for me at least so you may have to run out and buy a larger ring clamp. Good luck

Whenever I add a mod that changes power which is so highly computerized and monitored these days, I always pull the battery for a reset.

It may be an old-fashioned sentiment, but I prefer the ECU to re-learn itself on a fresh table of values, lol

Yes the ECU will adapt, but my understanding is that it usually takes multiple WOT runs for the best results.

from Ebay, it was slightly used for 10,000 miles the guy said, saved $175
He was asking the other guy about having to do WOT runs for best results. While not entirely right, it's not wrong, either: the ECU learns from WOT runs, too, since most daily driving never really exceeds 2500RPM. Your regular daily driving will have learned itself, though, regardless of WOT runs. Any improvement in daily driving behavior after WOT runs is more that doing some hard runs "cleans" the engine out a bit which can help make it feel more "peppy" for awhile.

where did you get that from ?
Multiple different tuners have explained this fact and that extra power wasn’t achieved until several WOT runs. That’s why some people don’t show much gains when doing back to back dyno runs after mods or map changes.
Most modern cars runs real time closed loop for fueling. That's why piggy backs like the JB4 even work. There is no need to pull the ECU, battery or do any WOT pulls. AFR is always real time adjusted.
Only partially true. Yes AFR is real time, but ignition timing adjustments happen mostly during WOT runs. This is more noticeable when adding extra boost like with a tune, but pretty sure Tork and even Terry said it took several WOT runs to show gains after adding their intakes.

There is nothing to adjust too. The stock airbox and paper filter supplies more than enough air to make this engine roar, even with a tune. What you bought is additional sound under the hood. The ECU doesn't have to adapt to that, lol!

Intakes have been proven to increase horsepower. And yes, ecu will adapt to that.

Having just installed the injen airtakes it seems like the rear tires break loose more than before when the boost kicks in.
More power ? You would think but definitely believe most of the 'wow, this intake really added power' is in the head from the thrill of the sound
could really feel 10 more up/tq much ?
Hearing the turbos and bov worth price of admission for me
