AP use with Nano - notes from Cobb

[pwrful4]

"Requires a significant amount of tuning in order to run properly." The +SF maps that are designed for the Cobb SRI don't match up well with the CP-E Nano as I experienced. 93 Octane map was jerky and 91 fuel trims were off.

Maybe if you swap out your Nano for a Cobb SRI it will work better

[coyfish]

God I hate reading these stories. Just when im all excited about eventually getting an AP, people talk about how terrible their cars run.

[ymic]

AP tunes are designed to run using cobb's parts. which is why i have a standback cause it's user tuneable.

[eg6motion]

scary to think how two SRI's could really be that different....

keep the nano and get a standback :)

It won't matter in a couple weeks once access tuner race is released.

[pwrful4]

Actually it does matter, because with access tuner race you'll have to take your car to a certified shop and pay to have it tuned. That costs roughly $150-200/hr, which will provide a map but hard to tell long term reliability and fuel trims.

I've decided to swap the Nano for the Cobb SRI and try that. Did Cobb ever fix the issues of the brackets breaking?

no. I recommend running without it. I have been running like this for awhile and the silicone tube barely moves without the bracket anyway

[CnoTataymo]

Does the Cobb SRI have the airflow straightener design like the CP-E Nano?

Does the Cobb SRI have the airflow straightener design like the CP-E Nano?

yes, its the first to have it

[CnoTataymo]

Then the only difference is one is silicone and the other is aluminum piped. There shouldn't be much difference performance wise.

[RC08MS3]

hm.... so does this affect the same as a CAI? for instance they say Mazdaspeed CAI + 93 octane, whay if you have the CP-E CAI, people had the same issues as the SRI?

[eg6motion]

didn't think there was a map for CAI anyway?

Actually Access tuner race allows you to modify the tables yourself. No tuner required so it won't cost you anything.

Those with the cpe cai the non intake maps work best. There are maps for the ms cai but they don't work well with the cpe cai.

Dread, youre current, accesstuner race is user tuneable, accesstuner pro or something like that is for professional cobb licensed dealers to tune.

shittttt, my car runs smooth as butter with the nano and the Cbb TBE with AP tune. Should I be worried?

[pwrful4]

If it runs well with your setup and the number are good such as ltft, boost, afr, kr, etc. I would stick with it. I was running Stage1+SF 93 Octane v103 on my 09MSE with just the nano and was getting jerky partial throttle in 3rd and when I switched to the 91 octane map it fixed the jerkiness but the ltft's were off.

In regards to ATR, I don't think any of us besides Christian has the time or knowledge to tune these cars professionally. Think about it you'd be guessing with independent variables, flashing the car, and having to wait 100 miles before you go WOT it to see if it's safe and within proper parameters, all the same time you could be running an unsafe tune.

Pwrful the ATR software is supposedly very easy to use.

[scatt nasty]

Not sure if someone mentioned it, but when CP-E Made their CAI they made it so the fuel trims were very very close to stock, which is why when running their intake with the AP you use the maps that include a stock intake.. I myself bought the cobb SRI and sold the CAI so I could run other maps....

Question: So when ATR comes out, will all you high speed guys who are familiar with the software gonna post some how-to's in regards to mild tuning and what not ?

I would really like to run my BPV VTA =)))

A few of the guys that went to the Plano seminar said its incredible how user friendly ATR looks to be. You're not guessing with anything...cobb spent hundreds of hours on developing the software and excel files to make it user friends. If its anything like the subaru ATR it won't be bad at all.

Here was an example a forum member that saw ATR said about changing boost:

You take a log with boost. Copy boost values into ATR spreadsheet. Spreadsheet converts boost values into the torque targets the ECU reads. You put in desired boost in spreadsheet. Spreadsheet spits out desired torque target. Copy and past torque targets into ATR. Done with boost.

Haltech will be doing an extensive video tutorial over on msf.

Question for you, did you get the Denso 1-step colder plugs that are recommended by COBB when you installed the AP.
I noticed an improvement as soon as I changed my plugs.
The NANO should not make a difference.
Plenty of guys out there running it with the AP and no problems.
They recommend you do the catch can install too.

I was under the impression that cobb has an oiled filter and cpe is available in dry

I hope so.(freak)

[PCspeed3]

I recently switched from nano to Cobb, I noticed that partial throttle hesitation went away completely, and it was just smoother all around.

was that with or without the AP installed?

Whats wrong with that? Subies and Evo's have been doing this for years. The average tune costs about $300 and its worth every penny. BTW, most tuners dont charge you by the hour, they have a flat rate for a tune and if it takes 1 hour or 4 hours, its stil the same. If your one who likes to change parts like your underwear than a user tunable system is better for you. If you are like most and want to add a couple mods and have it tuned to make the most than the AP is the absolute best option, no question. Also, any worthy shop will stand behind their tune,a s long as you didnt do anything to change the tuning parameters, sort of like your factory warranty........

IMHO, the AP is one of the best modding solutions available to the MS3 community, its just too bad that most people are so critical which has made COBB not want to deal with this community.
