Default Cobb Stg2 Before and After?

I've pretty much got a Stage 2 Cobb setup and am sending my ECU in this week for a reflash. But I already have a MBC and am wondering how much power a typical reflash will provide for someone who already has a MBC..

I do understand the reflash effect timing and fuel mix as well as boost and I do know that the reflash will be a lot smoother... but how much torque and power do you guys think it'll provide?

If you're coming from a MBC, you'll notice that boost from the ECU reflash won't come on as abrupt as the MBC. So in a way you may feel that you lose torque. But that torque you feel you lose is distributed evenly throughout the entire RPM band. The accel is way more linear and pulls hard all the way to redline. Much better tradeoff. Not to mention better driveability, no more stumblin while accelarating and much better on the partial throttle high EGT issue

I agree with the above post. At takeoff it doesnt feel as punch as having a MBC but you pull hard to redline and thensome. Also the herky-jerky feeling at 2500-3000 rpms is gone. No PTFB issues to worry about and the knowelage that your not having to worry about temp changes spiking boost is awsome....

Well, this isn't quite scientific... but it'll beat a butt-dyno. Here's what I'm going to do:

I did 2 runs from 60-110mph today at the request of my DSM buddy so we can "virtual race" eachother (he's in Boston, I'm in Detroit). The fact that his FWD Eclpise with aftermarket turbo is more suited for higherend runs like that is a whole other topic, but he has a point in that reaction time, traction and what not are not factors - just horsepower.

So, my 2 runs were 12.79 and 12.72. I've never been to the track, so my technique was limited to "hit the gas". I'll get the reflash and do 2 more with the same amount of gas in the tank. Then I'll wait a few weeks and do it again if I'm not in jail at that point to see if the ECU is going to learn.

Just make sure you give the ecu time to learn for a few days b4 doing your testing. The car gets stronger and smoother after a couple three days.


COBB Stage 2 for a couple of weeks now, loving it big time. I am afraid for all the other people on the streets with me.

Later,

I'm debating whether to get a Cobb Stage 2 reflash now or wait until their other Access ECU tools are released. What is the timeline for the Accessport and Accesstuner?

No point in waiting because they will just have you pay the price differance if you want it later... besides, you might be waiting a long time.

dont expect the access port to be out anytime soon, they cant even falsh teh MY04 wrx yet! I sent mine in and they sent it back said they cant do anything with it... subaru changed the ecus for MY04, its harder to tune I guess.

It's not that they are harder to tune, it's just that the ECU has to be cracked before they can do that. It took a long time for the pre-04 ECU's to be cracked, but I assume it won't be much harder to crack the 04 now that they have a good idea how it's done. The 04's havn't been on the market that long.

Quick question. What are the middle letters of the second line of coding on your ECU? "AJ" or "AH". I just got the Prodrive PPPst2 and I have a late build 03 with an "AJ" ECU and they had a hard time with mine also.
