So it seems as though most people just install their AP and ask questions or say its awesome. I would like to be a little more in depth with it. So here we go.

2011 WRX hatch
Currently 8359 miles on it.
All stock
13.4 @ 98.44 best
23.4 mpg average

150 miles into Stage 1+AEM with NWG Map
Boost around 15psi
Car is smooth and responsive
25.5mpg
Gonna switch to HWG Map in preperation for the track

Stage 1+ AEM with HWG Map
Boost around 17psi
13.11 @ 103.77

Stage 2+ AEM with HWG Map
12850 miles on cars
Boost around 17.5-18lbs
26mpg
Did not get the full results I was hoping for. Feels like boost drops off too quickly.

TP Stage 2 with AEM
13100 miles
Boost around 19lbs
12.92 @ 106.5
26mpg


I will be playing with my AP a lot and using many of its features. I hope to be as detailed as I can in order to help give some insight to those thinking about purchasing an AP.

Any questions along the way, feel free to ask.

AP to be installed Thursday night

Great. I am considering a purchase and will be tuned in on your results. No pun intended.

Ok, finally received my COBB AP so here we go.

I recieved the COBB and the disk was not in the package, nor the cable to hook the AP up to the computer. Neither are big deals. Went to COBBs site for the AP Manager, downloaded pretty quickly, then grabbed a wire from my PS3 remote. Solved.

While on COBBs site, I downloaded the Stage 1+ with AEM and also the Economy Map. This week I will be using the Stage 1 with AEM map, after the track I will try the Economy Map out also.

So, onto the experience.

Install into the vehicle itself is pretty easy and straight forway. Plug it in, turn car to ac/on, let the AP go through the motions. Once installed, I loaded my map, I then immediately went to the launch control setting and turned that on to 5100. Perhaps too aggressive for some, but hey, thats where I wanted it.

The car is certainly different. The power is now smooth, and not a sudden surge that falls off. It pulls to redline very well and I would say it is certainly noticeable. Launch control is awesome and makes the process a lot less abusive on the clutch, IMO. I use the e-brake as part of my launch technique and noticed no scent of the clutch typically involved when I launch hard sometimes.

The biggest differences will all be seen when I head to the track on Sunday. Im hoping for high 12's at atleast 103. That would be a half second improvement and an extra 5mph.

Any questions, feel free to ask.

Im interested in getting the AP but do they not include the software or the cable on accident? As far as getting on the gas I know there's a big kick as the turbo spools. Did that initial kick get distributed elsewhere in the powerband?

That's what I understood from when you said it smoothed out. Please correct me if im wrong.

I actually bought my AP used, so the previous owner just didnt include those. From our agreement, it was supposed to be complete. Not a big deal though.

As far as the power, opposed to a surge at like 4-4.k with the stock tune, boost seems to smoothly come in and its a nice clean pull to about 5-5.5k and then I can notice that boost is tapering off. As it does in WRX's

Don't use launch control that high on a stock motor. Ring lands don't like it.

Gotcha. I love the punch the stock tune gives even though it looses alot of the pull towards the top end. Have you done any research into whether or not a pro tune map would be able to be put on the AP?

Im considering getting a pro tune but if I can't us the AP to utilize the multiple maps it would be pretty pointless to even look into the AP

What two connectors are you connecting? All you need to do on the 08+ wrx's is plug into the OBDII port under the steering wheel.

Yes you can be protuned on the AP. A simple search would have yielded your desired answer.

I noticed my after my AP flash that my power dyes off big time after 5k. I didn't notice it as much before the flash. I am running the low waste gate map and boost is still low at redline sometimes only at about 10 by redline.

Cdj, thank you, I will consider turning down the rpm then or perhaps only use it at the track a few times.


Pleiadas, the wires I am referring to are under the carpet on the passanger side. When these two are connected, it turns on the ecu diagnostics and then allows the ecu to be flashed. The AP itself, foes not plug directly into this area, but into the obd 2 port as mentioned.

BBQ, what is your peak boost? Perhaps the NWG map would provide a bit higher and more desireable boost level.

We do not currently include CDs with the AccessPORT anymore as the most up to date version of AP Manager is easily (and freely!) downloaded from our website.

I'm glad to hear it sounds like things are running great for you so far!

Peak boost on normal map was only hitting 13/14 so I switched to the other map as recommended and now it boosts to 17-18 but by redline is only around 10.

Thanks Ian, everything does seem to be going well. Not having the CD is certainly not an issue, as the AP manager was easily and quickly downloaded.

I will have to see what my boost is by redline. 10psi seems pathetic, lol. Mileage on your car? Cracked turbo or a leak maybe. Idk

Np. I know from experience. :-(

It is pathetic. Car is a brand new 2011 STi. Just hit 2000 miles. Honestly the stock tune felt better to me.

I live in Denver Colorado so higher elevation. I dunno if that has anything to do with it or not.

The elevation certainly might be playing a part in that. It has been brought up in similar situations regarding boost issues with the AP. Most we told to go with a protune on a dyno. The OTS maps are so broad and generic. They theoretically will work for most cars of that year and mods, but clearly there are conditions that don't make every application equal.

Yeah I would like a pro tune but I am still all stock and it it just seems pointless to do one now. I would rather wait until I am stage 2.

The reason the stock tune felt better is a combination of a couple things. Altitude+ots tune is going to be richer than a car at sea level with the SAME tune.

The craptastic emissions based stock tune felt like it had more balls because its tuned to run leaner until ~4200 rpm.

You can get away with less injector at altitude due to atmospheric pressure being less than atmo at sea level. I bet you lost a lot of tq by running the ots map with tuning for cars that are at sea level, when you are at 5280 ft.

Honestly I bet if you got a protune, you'd be really impressed at the difference between a good stage 1 tune and the stock tune. I know I was. Stage one was a lot smoother, and definitely had more pep than the stock tune on MY06.

However I do agree with you for waiting till you have a downpipe and can get a stage 2 protune. There's no point in tuning stage one right now and then a few months down the road shell out another ~$500 to get tuned for stage two.

Another sidenote, I know its a bit early, but I am averaging 27.3mpg over the last 50 miles or so with my stage 1+ AEM tune right now.

I also feel like at idle, the throttle isnt as peppy/responsive. Its hard to explain, but I feel like I require more throttle positon to get the car going and dragging out the clutch just a bit more then previous. Just an observation.

Yeah at your elevation the barometric pressure is probably 12.2, then throw in the weather and it might be even lower. There are comp tables to keep your turbo from overspooling and going beyond its volumetric and thermodynamic efficiency.
With that said, go stage 2 and get a pro tune. I would almost guarantee that if you had a wide band you are running too rich. But as was pointed out above the stock tune is leaner so for your elevation it might appear to have been better.
