Then it's an iPhone problem. They display and play in a real web browser just fine. These are all embedded YouTube links, so I guess your iPhone isn't handling the embedding tags correctly.

I'm gonna try to change the Youtube BBcode tonight if time persists. Then you will be able to see the youtube links on your iphone.

thanks

I can tell you that it has made a huge difference in sound (quality and volume)
The car still sounds pretty normal while cruising, (Zero Drone) but when taking off normally you can now here the exhaust note. And at WOT, wow!!
It's not super loud by any means, I think some people would still say that it's mild, I'd say that if it was between mild, medium, or loud(race) this would now be a medium, where with just the Nismo catback it was mild.

This is exactly the kind of tone and volume that I hoped for when I first installed the Nismo, but I was pretty disappointed. Now it has really come to life. IMO it should have sounded like this from the get go, but I guess Nismo engineers were forward thinking, knowing that a lot of people would probably install HFC's of some type and eventually end up with this result.

There is no question the car is breathing much better, the throttle response has improved and with out a doubt it it quicker.

Amplified Motorsports in Monterey Park did the install in about 2 hours, thanks Paul, Lou & Jet!!
Oh, they also installed my cross drilled/slotted rotors at the same time, so the cats didn't take up the whole time.

Had the Berk's added yesterday.

Also cleared the learned values as suggested by Berk Tech. [in an earlier post] as part of the install. A suggestion to Berk: These instructions should be included with the Berk HFC's.

This mod. not only made a Big difference in sound but also a very good increase of butt pressure at regular acceletration and WOT. Definitely an improvement in performance. I also have the Stillen Gen. 3 intakes so this has helped make this package work better.

The Berk exhaust system also sounds good but I like the look of the Nismo exhaust tips much better.

Those Instructions from Berk..................................

Originally Posted by BerkTech View Post
The ECU will only look at the secondary O2 sensor during closed loop operation (i.e. lean burn, steady freeway cruise, idle, etc). The ECU will make small adjustments to the fuel trims based on the small adjustments made during closed loop operation. This is on the order of a few percentage points. I don't recall ever seeing anything over +/-5% in the last couple of years.

If you guys have ever called Berk for tech support you've heard us say, "Clear the ECU learned values before running the HFC's. You will run less of a chance of throwing a CEL light". Over time your ECU may have adjusted based on your driving habits. By clearing the fuel trims you give your ECU a chance to start back at zero and readjust to the new cats. The cat is in essence an oxygen storage device. When installing a BERK HFC that flows twice as much as the OEM cat it does not have enough contact time with the catalyst to "scrub" the exhaust gas and let the reaction occur. So the O2 readings will be different. Most of the time the thresholds of CEL or no CEL are large enough that the ECU will readapt and the CEL will stay off. However some of you who were already operating on the outer range will pass that threshold after a few drive cycles and illuminate the CEL light.

During driving situations where the engine sees load it will completely ignore the secondary O2 sensor and go off of it's pre-programs maps. On one of our race cars we actually did not use any O2 sensors at all! We would run completely off the pre-programed maps on the stand alone. We would make small tweaks to the maps for high altitude race tracks and summer/winter weather.

So, the moral of the story..... the secondary O2 sensors technically DO make tiny fuel adjustments in concert with the primary wide band sensor in the header, but only to make the car run as clean and lean as possible during steady cruise. From the stand point of the car enthusiast, they don't do squat!

And to set the record straight in plain black and white:

Berk HFC's are not SMOG legal in CA. Can they pass a sniffer test? Yes, all the time. But Berk Technology does not guarantee emmisions performance.

The vast majority of you will never thorw a CEL. However there is a very small percentage of you who will throw the occasional P0420/P0430 CEL. Down the road there will also be a very small percentage of you who throw those CEL codes with the OEM cats!

Hope that gives you some good info to chew on!

Cheers guys!
Berk Technology
