thank you

 

So, a noticeable, yet currently unknown, amount of benefit. Thank you for the reply.

To what would you attribute the noticeable drop in both torque and power outputs at about 3600 rpm? (You may have addressed that question earlier in the thread. If so, I apologize for forgetting the answer.)

 

Most driving occurs at part throttle, which is difficult to graph.
Sport Mode and Octane Adapt maximize part throttle response and torque, most of which is not limited by the cats.
Hopefully, the folks who have the chips already will start chiming in (once they get injectors and/or good weather).

That said, I spent a huge amount of time on the WOT part, even though it is usually used for only a few seconds at a time.
The with-cat full throttle graph will be somewhere between the green and red lines. I'd imagine most of the graph will be near or above the blue line.
I might go dyno with the cats and new chips just to see.


The dip at 3600 is the transition between the flappy closed torque peak and the flappy open peak. Below is the factory graph of always closed vs. always open.
Disregard the higher dashed line below 2400 and above 5200. I tried closed and open on the dyno - same.
I ended up just opening the flappy a bit before the stock rpm to eliminate the 'shark tooth' you see in most S4 dynos.

The smaller dips (3250, 4500) are where the cams and/or intake won't make any more power.
They appeared as I brought the power up in new places around those areas with higher resolution maps.
Around 5000 the cams are really 'sleeping'.

 

I have Ken's new chips and will have them installed and tested over the next couple days.

Ill report here once ive done so, stay tuned.

 

Ouch.

Ken - you no call, you no write. Why you no like me no more?

 

Why "ouch"?

Ken said he wanted early adopters to chim in.

Did I miss something?

 

Brendan, the purchase link is on his site.

 

I asked him to be an early adopter. I am joking around with an old friend. No Worries.

 

Oh. I'll take a look, thanks.

 

Cool cool...Kinda figured after the fact

 

I missed the announcement that they were available. Ken, do you have installation instructions available so I can get an idea of what would be required?

 

Great going Ken!

 

I have a set here too, and hoping to get them in before the weekend.

I will be trying the 12-hole 24lb injectors to see if that is a viable option for our cars.

Any updates on the chip install and the different injector types you guys are trying?

 

If it's been mentioned over these pages, I apologize, but what is the new duty cycle with these 24s?
