[COBB Tuning]

Firmware updates, map downloads, and new ROM submissions should all be working now. Make sure you have the latest version of AP Manager installed too! APM 2.0.2.3 is the latest release (out of Beta).

Can someone take a look at this datalog. Stage 1 aggressive, no other mods, 93 octane. 30MPH 2nd gear through somewhere in the middle of 4th.

Thanks,

Why is my actual boost so much lower than requested boost?

I installed the latest beta stage 1 aggressive 401 map and took my car for a drive. After some spirited driving, I got a P29CE error code and service engine light. Car started sputtering and shaking. I immediately stoped the car, changed the map to stage 1 301 aggressive, and drove home. No more errors and the car seems to be running fine now. I wondering why so many people are having issues with 401 maps? BTW, this is the first time I have ever had any error codes thrown due to COBB, I'm staying away from 401 maps for now.

For those of you who track your car (AutoX) do you recommend not running the most aggressive tune as it applies to your specific mods?

Don't run Cobb now but just would like to know.

My personal opinion is that 4.01 uses higher boost settings and anybody that's on the edge of misfires a lower boost will get misfires on 4.01. As soon as a tried it I had to change my plugs and then I was fine.

My plugs are only 10k miles old. I wonder what else could it be?

You need to datalog and analyze how well your car likes the tune. If the logs look great stage 2+ aggressive then that's what map you should run for the best performance.

just installed my Cobb AP yesterday and I am very happy with the results! Now I have the daunting task of trying to figure out how to understand the data logs.

are there alot of known cases of boost oscillation with the stg. 2+ aggressive? I'm wondering if there are specific reasons for it or just random cars?

I'd assume (very dangerous word on this forum) that it's still an issue since the v40x maps are still listed as beta on the COBB website.

I got them with v301 maps lol

[blakonblak]

I have catless DP, and everything except section 3 is stock. Since my e92 is my DD, is running stage 2-drive safe? Or should I be running no tune?

In terms of safety I am thinking of it being harmful to my engine and thereby decreasing the life of my car.

Hi everyone Im considering getting the Cobb AP. Ive read that the AP increases the rev limit to 7200 RPM. Is this also true for the Auto trans or just the 6MT?

Its for both, but at the same time it is pointless to rev that high especially on stock turbos since they run out of breath up top.

Thanks. Do you know what the 6AT shifts at during WOT?

If you look at COBB's dynos (in the map notes section of each tune), HP peaks around 5,000 RPMS and last until 6,000. Reving past 6500 is only good for noise as the powerband falls off substantially at that point.

Dumb question: are you sure its boost oscillation or are you leaking? Possible that at Stage 2+ that you've got a leak somewhere. You don't list any of your mods in your sig, but if you have any OEM bits left outside of the map requirements (upgraded intake, DPs & FMIC), that either the OEM DVs or CP is the source of your leak.

If you do not manually shift, at 6800 RPM.
