First instruction on my SRI was to disconnect negative battery cable, not sure if this was to reset the ECU or just for general safety, but it did seem to have more jump initially so who knows?

Yeah, same here. But the god's honest truth is that I simply unclipped the MAF sensors before I remembered that I should have disconnected the battery. It didn't occur to me that the battery disconnect would be for the ECU relearn. Hmm. Looking back, the instructions with this kit specifically say, "No ECU reprogramming is required." But that just means it doesn't need to be tuned, not reset.

I should probably reset it and play around.

I've done the pedal thing. Honestly, disconnecting the battery is way easier, especially when it doesn't really clear any of your settings. The only thing you need to do is your windows, which takes 30 seconds. The pedal method can take many tries if you're not exact.

Didn't know that about the G and the window reset. Here's a real simple explanation on how to reset the windows, cross-referenced in case someone is following this discussion through my thread here:

I hear you on the brackets. My driver-side bracket started coming loose after about a month so you'll definitely want to keep an eye on it. You'll start to notice a weird rattling sound when at idle--it's the heat shield vibrating against your fuse box.

Been thinking about this today. I'm going to re-do those brackets with nyloc nuts and larger washers.

Whoops, time to update my sig line.

And you know what? These worm-clamps are bugging me. I need to get some SS T-bolts.

Very nice look John, Your bay looks so clean. You know that engine cover would really pop if it was sanded smooth as per this method

then color matched white. Just a thought, as I owe you a few

I disconnected the battery last night. 18 hours later, I reconnected and reset the windows. Strangely enough, the radio presets did *not* disappear. That was odd. Then I drove it around hard for 20 minutes in lower gears and heavy acceleration, to bed-in a new driving behavior.

While that was fun and all, it seems about the same to me. Oh well.

It's been over a week now since installing the intakes. Here's some follow-up.

I've removed and reinstalled the intakes a number of times trying to tweak the fitment just right. I'm using larger washers and nyloc nuts on the bolts to the heat shields, and that really helped.

The whole thing is really quite stunning looking, IMO. And I'm still very happy with the look. However, I'd like to replace the couplings at the throttle bodies with a couplings that are black instead of dull gray, and use some SealthClamps instead of the SS worm clamps it came with. Also, I wrapped the MAF wiring in larger wire loom, which is a cleaner look than OEM.

My first impressions on power and noise were underwhelming. Butt-dyno said "meh", and the noise was far less than I was hoping for. Pretty disappointed, actually. So I disconnected the battery overnight to reset the ECU. Hooked everything back up the next day, and same-as same-old. Then a few days ago I removed my hood liner, and now the noise seems just about perfect. Much happier.

And just today I swear I have this perception that the car has more grunt and throttle response than I'm used do. IDK what's different or what's taken so long, but is it possible that after resetting the ECU, it's been relearning how I've been driving the car a little harder lately, and adjusting accordingly?

Anyway... one week later, and I'm much happier than I was the day after.

I could be crazy, but I swear this car is moody. Sometimes, it drives great. Smooth power. Responsive. How it should be. Sometimes, it would go through one of it's moods and will drive like crap. Jerky, laggy, and unresponsive throttle.

I don't think you're crazy, it seems like sometimes the G is just extra bad-as$, like it just has extra pop, having an AT I could see this happening since there are more computer variables involved.

John, glad you're happier w/ the noise-maker, sounds like you're finding its' sweet spot. I think once you get some exhaust mods you'll really be happy.
It really is nice looking in there, and I'd imagine w/ a few clamp upgrades it'll make a nice difference.

I was thinking about trying the hood insulator removal but after hearing that it may be for paint protection I'm having second thoughts. My black paint gets hot enough & coupled w/ the hot VQ I'd better not push it.
