Default Very frustrated with my AP (why dont I notice a difference)?!

I loaded the stage 2 base map (93 octane), but I honestly can't tell if I notice a difference

Is there any sure fire way to tell if it works... arent I supposed to be wowed??? :sadwave:

I connected the green plugs, turned the key to on, selected the stage 2 map and let it load for about 30 minutes. Then disconnected the green connectors and started the car... the car wouldnt start. I took the key out and started it again, this time it started fine. I got on the gas a little here and there and felt no difference, I went on to a highway and gassed it up, but honestly still couldnt tell if there was a change.

It seems to be good up till 6.5psi, but then it seem like it doesnt want to go any higher in 3, 4 and 5th. I did manage to notice almost full boost in second, but that was after the gas was COMPLETELY floored to the ground, then it made a jump up there.

Please tell me I am still running stock because I really was expecting a big difference
Why is it so hard to get full boost?! Why cant I seem to notice 40 extra whp and 70wtrq?!

A few thoughts for you.... You should feel a huge difference at stage 2!?!?

Did it really take 30 minutes for the map to load??? This seems very long, I haven't taken more tha 15 mins. to load a new base map. You also mentioned that you conected the green plugs, did you also connect the white plug that came with your AP. You need both to load a base map. Did you unplug all the connections after you loaded the maps and before you drove it?? The easiest way to check if your right is to connect your AP, start the car and then select check current map on the AP. It should tell you if you running the stage 2 map. Also make sure you loaded the correct base map and not just a real time map. You need to load the stage 2 map as your base. (choose the load a new base map option in the menu) If you plan to only use the stage 2 map then do not load a real time map on top of your base. The base map is what the ECU will run and is the most important step in using the AP. The realtimes are used to swap maps without flashing to the ECU, so if you can't get 93 octane you can load the 91 real time on top of your base map temporarily and then switch back to your base when you get the good stuff (you can switch real times without hooking up any of the plugs once you have loaded your base map).

If all else fails call Cobb

What white plug are you talking about? I connected the green connectors, I wired the AP into the jack under the steering column then I loaded the map (this is how I guess I married it to my car. Afterwards I disconnected everything, started the car, and plugged it in again and checked what the current map is listed as and it says 93oct Stage 2.

I DeltaDash dyno'd mine and saw the improvement objectively (course I felt it too). You do have an aftermarket downpipe, yes?

I'm confused. Are you expecting to hit 17+ psi without having the throttle floored? It isn't supposed to do that.

Check your Cobb instruction book, or download from the cobb site. You have to connect white connector and green connector. (not just green alone)

Whan I loaded stage 2 I felt immediate power gains, improved more after a couple days driving and the ECU learned.

I do have a DP.

I feel the car pull hard in lower RPMS but the boost does not exceed .5bar at any point unless it starts hitting higher RPMS where it then jumps to ~1bar. If I remember correctly, when "stock" the boost gauge didnt rest at .5, it moved according to the throttle.

I have an 04 STi...

what is this white connector? I dont see any mention of it in the instruction booklet? Are you talking about the accessecu wire that plugs into the port under the steering wheel?

There is no white connector on an STi. You just do the green plug in the STi. And make sure you unplug the green plug when you are done of course.

Any other mods? What elevation are you at? What do you mean by "lower" and "higher" RPMS? This is under WOT?

Under WOT, I hit full boost at 3300RPM after which it slowly drops towards redline.

Regardless, it might be worth a call to Cobb if you aren't happy and don't think things are working properly.

at WOT I hit about 7psi from about 3300rpms-5k then it may briefly go to 15psi or 1bar just before I have to shift.

When I am accelerating through 1st, 2nd, 3rd I really havent noticed full boost once.

Oh and by the way, I tried the VALET MAP by switching to the real time map (base was still stage 2) and it worked fine.

I felt absolutely nothing when I first flashed stage 2 on my wrx. Took about 200 miles before I was hauling ass. Same thing with my friend's sti. He went from stage 1 to stage 2 last week and we felt nothing at first, but by the end of the week the car had an enormous amount of torque.

Really? Why arent others saying the same thing? It seems like I remember reading people plug it in and then start the car again and there is a huge difference... I wish I had a dyno nearby so I can just put all this wondering behind me and find the truth.

Anyone else agree with this?

Sucks flying by SOTP................... Dyno before and after or at the very least a few G-tech runs would backup any thoughts. These are cheap options for surefire answers when compared with the price of stage 2 mods.

What version base map are you using? Don't know about the STi but I had to first marry the AP to the ECU with the map that it came with and then flash another base map with the latest version from Cobb that was more fine tuned than the original map that it was released with. Check for updates on Cobb's site.

I got mine used so it didnt come with the "factory" stage 2 map loaded up. I had to go on my computer first, put the stage 2 map on my AP, then marry the AP to my car and load the v1.03 STG2 map up as the BASE.

as far as that "white connector", isn't that only for the wrx??

for the stage 2 91 oct map for the wrx, the map notes say: "Target boost pressure is 15.8psi +/- 0.5psi depending on vehicle and conditions. If after 1-2 weeks worth of driving you are still unable to reach target boost pressures, you may try using the HWG version of this map."

expect the car to "learn" and make some adjustments...

well I just went out again and this time used my Gtech on it. I cranked out a HP reading of 305hp with the stage 2 map and 260hp with using the stock map (and DP).

I guess I was wrong in saying it wasnt working... the performance improvement is just a lot smoother then I was expecting. I thought the difference would be very blunt.
