trey just posted this over in the cobb forum:

I'm going to start a new thread with updated beta maps to try. I just wanted to post in here again a point I've been trying to make for some time.

The Map Manager software has absolutely NOTHING to do with the function of the maps, the function of the AccessPORT, or anythhing else. ALL it does is transfer maps to/from the AccessPORT.

The version of the Map Manager you use has nothing to do with the function of the maps. The ECU Identifier you select also has NOTHING to do with the function of the maps.

Cheers,
Trey @ COBB

I think it's time for me to try beta map. Just when I was finally starting to hit target boost once again. I will most likely install map tonight or tomorrow morning. I will post results. In the meantime ppl with beta experieces, does the stalling problem persist, I saw one responce that it stalled with that map also. but in general? Also once stage 2 is up, witht the new map versions, did anyone experience trouble with those?

thanks,
Radu

trey was good about giving me beta maps to try to get rid of my stalling problem with Cobb 2.5, but after a few weeks and several different maps, i gave up.

My car's much faster and won't stall with Ecutek.

Hmmm. Is this true? I was just pondering getting an AP.

What's a 4EAT? Sorry, for being a N00B here.
I'd like your honest feedback about EM choices though. Although I'm admittingly looking for a relatively inexpensive choice, and want to be able to seamlessly revert back to factory for warranty work in the future.

4eat= automatic transmission. cobb's previous maps were fine with my car until they upgraded a little while ago. since then, the AP made my car stall repeatedly- almost @ every light.

there are lots of people with the stalling problem, but there are probably lots of people w/o it too. i guess it depends on the car. i'd recommend the AP if you're early on in your mods.

the only thing left for me to do for speed is an engine swap, so i won't need any more reflashes until that happens- which will, if ever, be in the distant future. the real time map switching thing was a novelty. the only reason to get the AP is to be able to reflash as you mod. i'm sure that cobb will get things figured out eventually... i mean it's been close to 2 months that they've been trying to fix it.

Default Beta maps on the Cobb website

Trey has posted some beta maps on Cobb's website. These maps are modified to prevent the stall problem. Try out the new map and report back.
At least one person has reported the stalling fixed by one of the beta maps.

So what did you do with your AP? Selling it? I still am thinking about getting one.

Oh, and thanks for the response. I had a hunch that meant Auto trans.

Yep, auto trans.... Well, I'm still a relatively satisfied Cobb customer at this point, and I haven't even gone Stage 2 yet. Actually if this little car gets to 285hp, I'll consider it a day and done... 140hp/liter is pretty impressive in my book.

I flashed with the newest beta maps last week, and my car's been running great ever since.
When they moved to the 2005 based maps like a month ago, my car didn't stall that often (maybe once a week), but the low end was really horrible. It was jerky, and very hard to drive. Something like stop and crawl traffic, or low speed parking lot driving was almost tortous. It was never like that before with the older maps. Now with the beta maps, my car is finally drivable again. The rpm's don't dip down at all like they did before, and it doesn't have the jerkiness that it had before. You should definitly give the beta maps a try.

Forgive my ignorance (using a stock ECU). So why couldn't you just flash back to a previous mapping that worked well? Seems like your only going forward?

if he updated his AP w/the newer firmware then he can't.

does anyone have the older map versions still? Specifically v1.18 stg 1 for 93 oct. or lower for AP version 1.5? I guess we can try to load those older maps, see if those are working correctly and improve drivability. Only if we didn't upgrade AP firmware though. Are there a lot of chages between older stages and these new maps? Thanks.

So does the AP allow you to read the factory settings of the stock ECU, and then dump them to a file or anything? Seems that would make the most sense, for when you wanted to temporarily revert to stock. I'd hate to have to use someone elses 'Stock-like' interpretation, and instead would want to have the exact version that is in mine now.

I have a stock '04 WRX and it seems to run very stable. Have noticed lag going from CL - OL, but can't say that I've noticed the pinging that has been reported elsewhere.

I am interested in the performance gains of the Cobb product, though.

I really wish I could do that, but once you upgrade your firmware you can't go back. I was very happy with the original maps.

As an update, my car stalled for the first time today with the beta maps. It was about 60 degrees out, first time driving my car today. Car stalled coming to the first light from my street, about 1/8 of a mile of driving. Light was red as I came to a stop I pushed in the clutch and saw the shiny light display telling me my engine had died....darn...i thought these new beta maps made my car run a lot better, but they haven't fixed the stalling problem. When I restarted my engine, it was idling really fast (like 3,000 rpm) for about 10 seconds, which it never did after a stall before, but maybe that has to do with the changed Trey made to the IAC to prevent the stalling. It would be nice to find a pattern among the people who are having stalling problems, so let me give a bit of info, maybe if the rest of you post stuff we can find a pattern:

04 WRX Wagon MT, purchased 12/03
bone stock, no engine mods, no intake mods, no BOV, no grounding mod, nuttin'
I live in Northern VA
Always use 93 octane gas either from Exxon or Sunoco
It always stalls when the car is not warmed up (open loop), never had a stall after about 5 miles of driving
It never stalls when just sitting there, it always dies when I'm coming to a stop and press the clutch in. Seems to happen if i push the clutch in while i'm still going 40mph, or almost at a stop
Ambient temps don't seem to matter, I've had it stall at 85 degrees and 35 degrees.

that's about all relevant info i can think of

Well I have noticed that all of the users with the stalling problems have 04s.

Supposedly part of the Firmware update was that the new maps were based off the 05 firmware instead of the 04s. So it would make sense that there is some other difference between the 05s and 04 base maps that may be causing the issue (though Trey says that they are nearly identical).

Are there any 05 owners that are having stalling problems that weren't occuring previously with the pre v1.20 maps?

Update:
Answer is No. Problem is caused by using 05 maps on the 04s. i wonder how long it will take for Cobb to either figure out what the difference is and fix it, or to use the 04 maps as a base instead of the 05s. . .
