Hey gang,

Figured I'd post here as well since we have a crazy knowledgeable bunch who are always eager to provide some insight...

Your valued feedback is greatly appreciated!!!

-----------------

Hi Christian,

I have a MS CAI and CB exhaust, that's it. No downpipe or full turboback.

Why is Stage 2 map suggested in your latest MS CAI map update???

My wishlist map is MS CAI + CB + 93 octane.

Thanks!!!

-----------------

Charlie replies:

Probably a lack of cars, with the mods/octane you want, for COBB to test whether it is via remote datalogs or onsite dyno testing.

-----------------

My reply:

I would agree for the 93 octane part, but I would beg to differ on the MS CAI + CB exhaust setup. There were several replies corroborating this config on the survey thread.

Ultimately, my question/ask is: will there be a Stage 1 for MS CAI + CB (regardless of 91 or 93 octane) as I have no immediate plans of getting either a downpipe or full turboback (which is reqired for Stage 2 maps according to everything I've read).

Thanks again!!!

I'm in the exact same boat as you, same intake with catback and both cats still in place. (Except I'll need a 91 octane map, no 93 here in Ca) Christian told me people with test pipes and stock downpipes are ok to run the stage 2, but with both cats its not recommended. He still doesn't have anyone beta testing our configuration. I might do it, but I haven't ever done any logging on my dashhawk, and I'd rather run a tried and true map. I'm still considering it, I'll probably end up being the guinea pig on this one. Either that or go back to my stock intake and run the plain OTS Stage 1 map.

I am the beta tester for the map you are talking about see mods in my sig, no DP. Stage 2 doesn't always mean you have a DP. Read the map descriptions don't assume.

EDIT: Sorry not trying to be a jerk, I just have a headache. But really read all the way through each of the maps because each one is different. Not everything is set in stone as stage 1 and 2.

^^^ Seems pointless that there should be 100 threads about the AP when a couple of pages of reading should do the trick. the 53 page thread about the AP has every other person asking about what to run, "mods in sig". Run what works best. Without someone who is capable of tuning the AP for you specifically you're gonna have to be patient and let christian work out what's most popular.

I posted a new thread since my question is specific and applies top more than just my own individual needs according to the survey post on the COBB forum.

That said, I read the other post daily with great interest.

I didn't assume and did in fact read the map notes. Verbatim: Stage2 using 91 octane fuel. Requires turboback exhaust with a catalytic converter. The full map notes themselves do not elude to the fact that these hardware requirements are NOT mandatory.

I was not aware that downpipe or full turboback was NOT a mandatory requirement for Stage 2. Hence the question and thanks for answering!!!

Thanks again to all beta testers and also thanks for the replies to this question, even if providing an answer was a source of annoyance ;)

OK, who's the dumb-ass now... MS6-582, I read you loud and clear.

A little deeper in the map notes: Additional modifications such an drop-in replacement filter,
underdrive pulley, and cat-back exhaust system are still within the acceptable
parameters of this calibration.

I read about 45/53 pages of the AP post...but I forget what I read since I didn't think I would get one.

Anyways since I don't want to start a new thread....the Stage 2 91 Oct seems to cover only the turbo back with cat. Problem is I have a FMIC/BOV/AEM CAI/TB-no cat and soon to have speedies turbo inlet... I assume the Stage 2 is safe?

You can take that tail out from between your legs, One big difference between MS6-582 and the others and you and I is that they are running a race pipe, and we still have the very restrictive stock 2nd cat in place. There is no way that tuning parameters won't be different between cat and no cat. So I don't think your post is totally ridiculous, there is no stage 1 MSCAI map out there right now that matches your mods. The beta tester needs to have both cats in place to make it legit for me. If I had a test pipe I'd definitely try out the stage 2 map.

But yeah, I'm starting to lose track of all the COBB threads too... :)

I think the bottom line to all this is that there are very few people who meet the criteria for any single tune. Even if your car is modded exactly as the map instructs, there's a 99% chance that you do NOT live in Salt Lake City, Utah, which means the map is already not perfect. No OTS map will be perfect for any of us (save for those beta testing), and we just have to use cautious curiosity and evaluation to find one that fits best for the time being. SOON ENOUGH we'll have a complete tuning solution, and all these threads will be null and void.
So instead of posting a list of your mods and a question of which tune to run, maybe try a tune, and post how it ran with your mods. That way we'll build a data cluster of tunes/locations (elevation)/mods/performance. I think well all learn more about the various maps this way.

just get a testpipe? :)[/b]
I don't wanna get nervous whenever I see a cop in my rearview... I've seen way too many people pulled over with their hoods open and a cop looking over everything. Here in CA they don't mess around with that stuff.

Jesus, is every cop a certified mechanic? Or just really really bored...

Tell me about it. They are really bored, and the problem is most of them don't even know what they're looking at when they open the hood.

U'd be surprised. I'm pretty paranoid myself as my exhaust is bloody loud. I've been pulled over based on the fact that my car is loud, then they look around for violations. =\

If they don't know what they're looking at, how would they know a violation if they saw one? I'm not sure i'd be able to function in that kind of society. "Here is your car, it's a brown car. It's 100% identical to all other cars, except for the color. If you like to go fast, choose a red car...."
I actually grew up in SD, but moved out here in like 94. CA has changed A LOT since then. Albuquerque is awesome. It's still kinda like the wild west in a sense. Most the people (cops included) don't sweat the petty things. Shoot we don't even have emissions in our neighboring city.

Like it has been said before, no map is going to be perfect unless you are the tester. That is why I became a tester. As Unichip said the biggest difference between each tune is going to be based on the Intake. If you are CLOSE and have the SAME INTAKE, try it. No one is going to be able to tell you what map works best for your car, NO ONE! Try it, if it feels good great, if not try another map. Or... become a tester.
