    Cobb access port v1.

    I recently bought a cobb access port v1. Unmarred.
    Not sure if I should put stage 1 or stage 2.

    I got a Dc short ram intake for now and a magnaflow catback.
    So it's pretty stock.

    And are the maps on the access port any good?

    If it is the stock downpipe you would want a stage 1 tune. A stage 2 tune requires a higher flowing aftermarket downpipe. Since you are only cat-back replacement o the exhaust that is not what you want.

    Have you put the parts on yet? If not, then hold off on the Dc short ram intake and just do the catback and then flash cobb stage 1 (with whatever octane fuel you can get, for example 91 or 93). If you plan on running that intake, then you will need to get a different tuning method (e-tune or pro-tune), as cobb off the shelf maps don't support that intake. They only support AEM or COBB intakes.

    +1 to everything he said.

    also, cobb's website will give you a list of maps available and will give very specific details on what parts you need to run the maps

    Be aware that Cobb no longer supports the V1 AccessPORTs. They do offer an upgrade program, however, to a version that they do still support. I'm not sure if the V1 qualifies for it anymore, however, since we're now on V3.

    The parts are already installed. And I'm waiting on exhaust headers with a turbo upper pipe.

    You'll need a custom tune for the headers...nothing Stage 1 or Stage 2 OTS will support headers...

    Does this apply to the 32 bit ECU's only? What are the ill effects of installing headers with no tune or a Cobb OTS tune? ..sidetracking, I know.

    FYI...There are only 16- (2.0L) / 32-bit (2.5L) ECUs.

    It can put you into untuned load sites. Without tuning for the headers, you'll likely net little in terms of gains, so it's not worth buying. While you may be able to get away without remapping the vehicle, you'd need to be able to datalog the car, interpret the datalog, and make adjustments necessary based on the logs. If you're unable to do that, as a general rule, it's safe to say "you can't install headers without a tune".

    My accessport says AE-Sti-PORT-06
    And the users guide says 2004-2006 so I'm guessing its ok to use on a 05 wrx

    v1's are model specific as follows:

    02-03 can use the same AP
    04 can only be used on an 04
    05 can only be used on an 05
    06 can only be used on an 06

    if you have sti-port-06, you cant use it on an 05.

    So I installed the downpipe. With the high flow cat. But the high flow cat is touching the water hose where the ac water comes out from.
    And after a while of driving, steam starts coming out when I stop on a red light.

    Any ideas?

    It is. But I was thinking in cutting a peace off.
    Could that be the reason steam is coming out of the air vents?
