^ which isn't a big deal. If you were planning on going with a stage 2, you might get the same results with the stage 1 since the afr is leaner.

 

For the most part, the only place where lean is potentially damaging on an N/A car is right at the torque peak, where it might ping in hotter weather.
That is why it is nice that we are getting this sorted now.

 

You have the RB intake and the RB duct, I was asking about just the stock intake with the RB air duct (no RB intake).

The reason I was asking is because it's one thing to put the stock intake back in, but it's more hassle to put the stock VFAD back in (and to take out the duct).

 

The VFAD can be ignored.

This is true - it does screw with the MAF.

I've worked the calibrations around a few different intakes, but the K&N v2 is one that got special attention. I've had the AP installed on 3 cars with that intake and I have the K&N v1 intake tube in my car (before the turbo, of course).
------------------------------------------------------------------------------------------


-I am going to purchase the AP but have a couple of questions before I do (sorry if they are a repeat of anyone elses):

1. The only mod that I have is the K&N v.2 (05, RX8, 6sp, NA). After watching mysql's dilema with his inatke on youtube, will this affect my 8? I know that his is turbo and mine is NA.

2. If the AP will work with my intake are the maps that would work best for me already preloaded into the AP or do I have to tune myself? If myself how hard will this be to do?

3. What types of gains am I looking at getting as far as power? I know that your website shows an increase to almost 250hp. However, I know that I will not get anywhere near that, so what is a more accurate figure? Will I be able to get over 200?

Thanks to everyone who answers questions for guys like me. This website rocks and I love my 8. Thanks again

NO. MySQL is struggling with a MAF tube that is almost 1/2 inch smaller than yours. That is nearly a 20% change and is a real challenge.
The calibrations that I provide are going to be much closer to what you will need and I will provide you with customized calibrations to meet your needs.

No. Your calibrations will be sent to you via e-mail when you receiver your AP.


That depends on how hard you are willing to push it. Since you are mostly stock, your gains will be less than someone who has removed their CAT and utilized an aftermarket exhaust.

Expect 5 to 15 HP.
However, power is not the only - nor the primary - reason to use the AccessPORT.
You will get an elevated (and smoother) idle, much more injected oil flow for engine protection, earlier cooling fan turn on points and better throttle response.

 

Hey what about the RPM cut off. You moved it to 9300 correct?

 

9200 RPM.
I can put it up to 10,000 if you like.

 

Jeff, I would like my rev limiter extended to 10,000, if you don't mind.

 

Jeff, is mine ready yet?

 

I can do that. Use at your own risk.

I wish. Cobb hasn't gotten me a new build of the software yet.

 

I would assume you are tuning out to 10k so it actually makes more power out there? Have you done any testing to see when you run out of flow and where?

 

As soon as I install the AP, my upgraded ignition and fuel injectors, i'm going to floor it to 10k and see if the blower keeps making more boost.

 

Good luck with that.

 

Yep, wouldn't be possible without those!

 

Thanks for your enthusiasm

Wait till you see my next trick

 

The OE PCM is hard-limited to 10k.

 

Curious, if we could datalog (via device like Greddy Intelligent Informer) would a custom tune to fit our modifications be a viable reality? The engines differ so greatly it would be the easiest way to get a safe yet engine specific tune. I'm NA intake, unreso test pipe, and catback exhaust; This datalogged tune would obviously come at an extra expense if you so chose...

Then again, if this would be pointless, let me know

 

The AccessPORT software does some really good datalogging.
Even Hymee's sCANalyzer will do an excellent job at it.
I ran my E-Manage in parallel for a couple of days when I first installed the AP to watch the injectors duty cycles.
Since you aren't directly controlling injector pulse width (the PCM has algorithms for figuring that stuff out), its really just academic to know that stuff with the AP.

 

I had a suspicion that was the case; under personal pref data logged info would be nice but for some reason I was thinking the AP didn't support logging just live data (but had the potential). Thanks for the quick reply by the way!

 

Heads up on the Cobb AP Stage 1, 2 and 3 NA tunes at

As for logging, try downloading ProLogger at www.efidude.com and looking at some of the data files I've posted. It is a neat tool and the price is right. (BTW I do not consider this thread hijacking as the AP does not data log and people are asking about logging data - Sorry Jeff).

 

I'd second that about you guys trying the Prologger sw to see the data log graphing. I think it would make what you're doing a whole lot easier to get the overall picture. Compared to looking at a column of numbers there's no comparison.

Here is a 3rd gear pull using the latest "U" Flash. Soooooooo nice and easy to read and see what's happening.

A/Fs, RPM, Lambda, Load, Speed Temp, TPS, MAF LLFT and Timing all can be in one beautiful graph!

 

Would the Mazsport Cooling Fan Control Kit be worth keeping since I now have the AP? Overkill? Thanks.

 

nope.

beers

 

MM and Ray ...
Do you think there might be some advantage to nitrous uses to remove/change the fuel cutoff to 10K?

(Sounds like it cannot be turned off entirely. MM"The OE PCM is hard-limited to 10k.)
