Cobb AP for the A/T
I was not sure where to post this thread but decided that only a/t owners would be interested and those m/t people would avoid coming here.
Jeff left my home yesterday after a two day install session on my 04, 4port, super charged a/t. Since I was first (super charged a/t), there were no starting points except those from Cobb.
Jeff can tell you the process and I can tell you the results:
1. My 8 now has a repeatable idle.
2. Some how he must have also added a new a/t when I was not looking because it now shifts like a new a/t and does it all the way to 8700RPM (it still does not like to shift above that)
3. Even under full boost there are positive shifts - no dragging or slipping.
4. While I have not yet measured it, we know that the gas consumption has decreased significantly. While gas consumption is not something I am worried about it would be a concern to others.
5. Jeff was not after power gains (yet) and just wanted a safe, conservative tune that was consistent. I do believe that he has achieved it.
There are a few areas of concern that need addressing but some of the concerns may be of a mechanical nature and over the next couple of weeks I will be looking into them. Jeff will also be asking Cobb for some additional releases of tuning areas that were not yet open to him and seem to be needed on my a/t.
I want to be sure to point out that Jeff went the extra mile with me so that I understood exactly what was happening and why. He also went thru the process of passing me new tunes.

Yeah, I was talking (PMs) with him last week and he stated an announcement was coming.
Jeff, if you need a 4 port AT 2004 with NO MODS (performance wise) give me a shout out. I would happily work with you.
Take care,
Brian

The Cobb AccessPORT is now available for the supercharged 4-port automatic.

This is really great news to those that are AT's and Fi'd.. After the turbo was installed I had to learn what the nuanaces were...
My biggest gripe was the "cat save" feature on decel. pop pop pop pop BANG !
This is the one thing i will not miss.

freakin' great news PHIL! - thanks for posting the updates, any plans to put your baby on the dyno? i'd like to see the hp/tq curve - also, you mentioned Jeff has already tuned a 6port AT - any results from that tune?
I can't wait to get my AP - damn shame i gotta wait...

GAHH!! - oh well, i guess i should be glad that this is even available for us
also, how many maps do you have? and how easy is it to flip from map to map? sorry for my ignorance - i haven't done all my homework yet n' i'm just eager to know
haha

I am also very interested in the 6 port mappings. I would be happy to work with Jeff on my '08. It was used by Mazda for certifying the Mazda Speed intake/exhaust for the '08 RX8's so I am not sure if they modified the mapping on it. They did dyno it but I unfortunately did not get a copy.
Just to make sure I am understanding though, Cobb does have mappings for the 6 port that work? Is it using the same AccessPORT that is listed for the MT's only on their website?
I am not quite readt to shoot my waranty to hell with a supercharger but I am very interested in increasing the horsepower in easily reversable ways.
Oh, and Phil, thanks for carrying the torch for us AT owners. MTers just don't get that some of us actually like to enjoy the ride even in traffic.

. Gosh you have to stop the car, turn the key back on, plug in the access port, pick your map and hit send. Now the really hard part is waiting 4 whole minutes for it to remove the old flash and install the new
. Need more maps? Send Jeff an email on his special address and usually within 24 hours you will have your wish. Then you just copy the new flash map off the Internet onto the software provided with the kit and into the AP. Since you live within a distance that he is willing to travel, you may just con him into a custom install - especially at the SO. Cal Dyno Days (shameless plug for Jedi's meet - this will cost him)
. Atilla, you know I was playing with you, it's so easy that even an old hardheaded fart like me can do it.
How many do I have? I think he left me with about 6 but until I confirm if something is not working correctly (boost bypass) he is holding off sending any more.

Jeff is coming down to So. Cal during the dyno days meet and is bringing several APs with him and also bringing a broken down bald fart named Charles R. Hill (boy will I get flamed). If your really interested now is the time to buy cuz he is talking about doing custom installs when down there.
Please keep in mind that you can't get big horsepower out of a stocker - just ain't possible. Some additional HP, yes but some mods will make the flash even better - again ask Jeff or Ray. Ya want a screaming dragon with 300hp + - get FI cuz it ain't gonna happen without.
Thank you for your kind words - I enjoy my a/t and feel the need to tell others that the a/t is as good as the m/t, maybe better but just a little different.
Jeff and I tried it on my car last week. Seemed to make a difference. I don't have any numbers as of yet. Tomorrow is a dyno session that I plan on attending, so I hope to get some numbers before and after the Cobb.

My warranty (engine)will be up in 8000 miles. Did you hear that Mazda? Now you can sleep at night.
But I will still have my Emissions warranty. So sleep light.
So I'll see if I can break 130 RWHP tomorrow.

I have NOT verified it on a 6-port, 6-speed auto.
If someone in Phoenix or L.A. (and is coming to the L.A. dyno day), I will verify its function.
That person will receive 15% off the purchase of an AccessPORT if they want one.

OK Atilla - there you go - you even could get a discount. I was mistaken obviously, I was sure he said that he had done a 6 port. Sorry Jeff, I must be getting old and hearing things.
It also has a ton of other features that address drivability and engine longevity in ways that Mazda does not on their own.
