Default Another proud owner of an AccessPort :)

Just got my AP on Tuesday but didn't have a chance to install it until today. I read through the manual once to familiarize myself with the install and what to expect. Then I went for it:

My base map is the stock map. Opinions? I chose it because I bring my car into the dealer for every scheduled oil change, tune-up, service, etc. So if they ever killed the battery, they won't know I flashed the ECU.

My realtime map is Stage I 93 Octane...or is it? After I initialized the ECU with the stock map for the base map, I disconnected the green connectors and pulled the white connector out. I then went to the AP and chose "Switch map" and went with the Stage I 93 Octane map. This only took a few seconds as opposed to 10 minutes (with the initialization).

SENDING DONE

This is the correct way to do it right?

I went for a long drive (45 minutes - mostly highway) and at some points drove the car aggressively. I do notice a slight performance increase but is that my imagination? I would say it's a subtle improvement but 45 minutes of driving isn't enough to know for sure. Low end wasn't too much different, maybe at best a little smoother. High end was slightly better. I smoked a Volvo S40/60 (couldn't tell) from an 85 mph roll (he asked for it) dropping it into 4th. Not bad.

Should I give it more time to notice more of an improvement?

Do you have gauges? If you have a boost gauge, you should see about a 0.01 MPa increase or a little more than 1 pound increase peak boost. Also, the boost will hold at a much higher level to redline. A typical stage 1 car on the stock boost gauge will hit 0.1 MPa and taper to 0.09 MPa at redline. Since you have a 2004, the hesitation between 3000 and 4000 rpm will now also be gone. The car should also feel a lot more responsive at part throttle.

You loaded the real map correctly. The LCD will not display anything to let you know what real map is installed, only the base map is displayed even though it's not the "active" map.

Give it a few days and it'll learn and be a lil faster.

From what i've read you need stage 1 to be the base map to see all of the benifits of the stage 1 map. Here is a link that explains http://www.wrxforum.com/cgi-bin/ulti...173;p=7#000091. There is a better explination by Trey but I didnt have the time to find it.

The Stage I 93 Octane map should be your base map.

It's not recommended to run the stock map as your basemap on a 2004+ WRX. Stage 1 and higher base maps contains modifications for the CL/OL transition and knock learning that is not in the Stock base map. Some 04 owners running a Stock base map and a Staged real-time map have experienced pinging that was fixed by reflashing with the appropriate Stage real-time map.

Stage 1 should be your base map (octane does not matter). Make sure you download the latest version off of Cobb's site. My Accessport (received early June) was not loaded with the latest version, for some reason.

So, what would I do when I bring the car in for service? I don't want them knowing that I flashed the ECU

That's a risk you take when you mod a car. If you bought a AP and don't use it for its intended purpose than it is a complete waste of money. Flash to Stage 1 base map. It is reliable and many dealers actually carry cobb parts. Before I got my AP, I actually had a salesman at the subaru dealer trying to talk me into getting the AP.

You can load the real-time stock basemap. That way unless the dealer resets the ECU by disconnecting the battery, he won't know.

MY understanding is that the only way to ensure that the dealer doesnt find out the ecu has been flashed is to unmarry the accessport before you go to the dealer. If you are going in for general service I would think you would be ok just flashing the stock map as your base. For general maintanence I would go somewhere else and only use the dealer for warranty issues. What boost levels are you running since the flash?

The stock map is not the same as the Cobb stock map, however as far as I know the dealer cannot detect that it isn't.

You need to flash the stage 1 map to get the benefits of the Accessport. The base map is how the car changes the fuel, boost and timing. The realtime maps are telling the base map what it should shoot (how much boost etc). I.E. you could flash the stage 1 map but run the stock realtime map and you would see stock boost levels but with more aggressive fuel and timing (smoothing out your power curve but probably not making anymore power)

According to Cobb's website, the last time I checked, the dealership has no way of knowing you have reflashed your ecu.

If you go into the dealer with a stage 1 or 2 base map activated they can.

On the WRX, when running with a Stage 1 or 2 base map and the stock real-time map, the car drives differently than running the stock base map and real-time map.

On the WRX, the real-time maps only affect fuel, timing and total boost. The base maps also change open-close loop operation (important for you 04 owners). You will also get more part-throttle boost than stock. Whatever Cobb does to smooth out the midrange so much over stock is still there when running a Stage 1 base map + stock real-time map.

Running the Stage 1 base map + the stock real-time map is a great option for you '04 owners who may worry about getting questionable gas (common in California). That way you get the open-close loop operation back to the way it worked in '02 and '03, but the car still feels exactly like the Stage 1 map except under full throttle where maximum power is down.

With an AccessPort, it's a piece of cake to switch back to a Stock base map, so if you are worried about the dealer noticing that you've reflashed the ECU, just flash the Stock base map when taking it in, then put back on the Stage 1 or 2 base map when you get the car back.

That's what I said, I just worded it very poorly

What drees said regarding base map selection is very important for us 04 owners.

Do you have a pointer to this information?

I ahve an 02, running stock base and S1/91 RT. Part throttle response is definitely changed by the RT map.

AS far as I've read, the only need for a S1 base map is to resolve the 04 open/closed loop issue.

If this is wrong, I'd love to know, since I've been having a few issues with the S1 map on my car.

All I can say is that I feel that my car drives exactly the same off of full throttle with the S1/91 base + S1/91 RT when compared to the S1/91 base + Stock RT. I should go Stock + Stock and see if I notice a difference there.

I did find this reference, so my Butt Dyno must be smoking crack:

I pulled that quote from this thread on wrxforum.com.

So my best guess at this time is that the stock maps that Cobb has are better than the stock maps that came with my WRX. Maybe I'll go to a stock base map, too and see if I can tell a difference.

BTW, what issues are you having with the S1 map on your car?

Low boost (lower than with the stock map) with normal S1. Got some pinging with HWG map on hot day, although boost is dead on target with HWG map. So switched back to normal S1.

Magnified hesitation around 2-3.5k part throttle. It's present with stock map but barely noticable. Very noticable on S1. Probably some mechanical issue, Cobb said I should check my plugs. Haven't had time yet.

My car definitely drives differently wot stock R/T vs S1 R/t. Boost level is a clear indicator.

Have you tried the stage 1 hwg map as a basemap with the stock map real time?

No. But I've read nothing to indicate that there is any benefit to running a S1 base map *except* for 04 owners.

HWG was dead on boost wise, but that pinging episode on the hottest day yet here this year, made me a little cautious.

Before I received my Accessport in the mail I did a lot of reading on Cobb's discussion forum and I am almost positive I read that you will have better results if you use your stage map as a base map on all WRX's 02-04. Like I said Im not positive but it couldnt hurt to try since you can flash the base around 100 times.

Good luck

I also think the same as you, but it would be so nice to know, even if in just general terms, how each base map differs from one another and how earch real time map differs from one another. This would help the end user choose different combinations of maps for their specific mod level and operating conditions, or at least know the benefits or drawbacks of running certain combinations.

I did post this question on Cobbs board a while back, no answer.

I would expect they'd have called that out in teh manual if it was the case. They did call out the 04 open/closed loop issue base map requirement when it arose.
