AP Questions!
I have been doing research on APv2 since I recently got one coming in the mail due to all the hype and me finding one for 550 that I couldnt pass up. So basically, I read how to use it and I have an idea of how to install it. I have not tried yet seeing as how I havent recieved it yet, but I'de assume that its easy since it just connects to the OBD-II connector under the steering wheel.
My real question is basically on boost creep on Stg 2. Apparently, even if you go stg 2 reflash with catless d/p, it will still have boost creep due to a mechanical issue. My question is that when cobb says "as long as you have one cat in your exhaust, you will most likely not have this problem." The reason theys say this is because the cat will cause back pressure which will stop the over boosting before it occurs. So does this mean that if i run like..a catless DP with stock sti cat back i wont have boost creep? (cause' i have a resonator and stock muffler)
also, chicken and waffles, i looked really hard for a v1, then i read that ap doesnt make v1 for the 07..CRAP!!

Re: AP Questions!
i did not know that . guess you'll have to rock the v2! but surrrioslee, you might be better off putting that $ towards a protune. $500+ just seems like too much coin to me for an accessport, even if it has all of v2's bells and whistles.wrxSIN wrote: also, chicken and waffles, i looked really hard for a v1, then i read that ap doesnt make v1 for the 07..CRAP!!
or get a utec? at least that way you can tinker with afr's, etc.

Good chance that keeping the stock axleback will prevent you from having boost creep, but you never know!
You can still get a ProTune with the v2 and it's definitely something I would recommend!

Eh I saw the V1 and owned a V2, I would not own a v1 if I had the choice. Was not a huge fan of the required external power supply and the serial action. The v2 is a small unit with no power requirements as it gets it from the USB bus. The price for the v2 is pretty good, I sold mine for $600 cash a few months ago. That being said you can also get a reflash tune w/o an access port, but it will be much easier to find someone who can tune via the AP vs reflash.

well, boost creep ONLY occurs on the 07s for some retarded Subaru mechanical deficiancy in the brain. And i was thinking about going straight pro tune, but I like having my options open. I also plan on using the Ap for a boost gauge sometimes since i have absolutly no gauges in my car to prevent me from blowing up. Also, if i remember, ill give cobb a call about the boost creep issue.

Re: AP Questions!
That's the ticket on the 07. I have the Utec, and I have been everything from Stealth back only to GT35R. I have seen lots of 07's have issues with the APv2. I think the Utec is a much more capable machine, and it gives you a lot more control.chicken n waffles wrote:wrxSIN wrote:or get a utec? at least that way you can tinker with afr's, etc.

There is only one piece of hardware, the other columns refer to the software a tuner can purchase to tune utilizing the accessport device.wrxSIN wrote:that really woulda broke the bank for me.

Running the 91 map with 93 gas will decrease the chance of detonation since they are not running as much timing and are a little richer (this also means less power). Most of the COBB of the shelf maps are very safe. I would have no issues running the 93 around here.

I've been using the APv1 93-octane stage-2 map on my 2004 WRX for over 2 years with 0 issues. I had the car dynoed and the AFR's were great: not to rich, not to lean. I haven't fiddled with it since. I'd consider myself a happy customer (other than the AP shipping with old firmware months after the new firmware was released).

Yeh, ill probably run the 93 map anyways, just a thought. also, how would i update the maps anyways? and anyone have any ideas on how to..well not mount the AP in the car, but have it so i can look at boost, etc. i probably wont have a perma place for it. i just want to run it so i can watch boost levels for a bit and see if they are safe.
