Do you have any logs?

Logging WGDC after PID and WGDC Bank1 would show if there are any boost oscillations (or rule them out).

I'm going to try to log that for you. If there is no oscillations power surging (and bogging on agressive) happen and power delivery is not always smooth. Just have to find out if bogging continue to happen as there is no check engine or nothing.

I posted my logs here #5708, I am on Stage 1 agressive with 93 oct, bone stock expect for Cobb. I really don't know what oscillations should look like and on what parameter, some veterans here said they look OK though.

Definitely don't see boost oscillations in those logs. If you look at the WGDC after PID and WGDC Bank1 during WOT, your log looks very smooth for those parameters. If you were having boost oscillations, you would see those parameters fluctuating above and below their targets.

If you could capture a log of 3rd gear only from about 2000 to 6500 we can look for any other issues. Obviously we recommend doing this on a closed course since the top of 3rd gear will put you at a speed above highway limits.

I am looking at my logs as well, but I am not sure what PID really means. I looked it up but don't quite understand, can you describe please?.

A PID is a type of control system. It's basically just the type of control system that the DME uses for the WGDC. If boost oscillations are present, you will see large fluctuations when logging this parameter at WOT (when boost should be staying more or less constant). Some fluctuations are normal... large overshooting and undershooting are not.

Does the P2096 and P2098 have anything to do with me running stage 2+ sport and using the bms downpipe fix?

Yes -- IF you aren't getting an emission test done anytime soon, take it off. It'll through off your AFRs, make the car run funny (rich or lean) and give you emissions related codes (like what you're getting)

yea but it happens even at partial throttle. it feels like the probs we used to have with earlier version 2s. linear version felt lot better though. im going to try out the 4.02 stock throttle tomorrow.

ATR - Pressure drop over IC

In ATR software. Does anyone know the relationship that "Pressure drop over IC"
has to do with the system. It is very cosertive for my IC so hoping to get some gains from a table modification.

Since the downpipe fix has a dialer could i turn it off instead do you recomend removing

It appears that they reduce the boost target by that much since the turbo is having to generate the boost target PLUS the drop across the IC. The good news is that while the code caps the boost target (18psi at sea level? About 15psi at a mile high) you can get some of it back by zeroing out that table. All other tables seem to have no affect on raising the boost once you're up against the cap. So anyway, that's one way to get a little more if you want it.

Thanks for the help. Lucky I got the flow vs pressure drop of sperco IC so will give it try. Most of the gains are at higher flow rates

IIRC, the DP fix has a "strength" dial, but there is no "Off" setting. SO it's gonna have to go to make sure your car's DME isn't calibrating AFRs incorrectly

I need HELP!

Hi Cobb team...
I have updated my ap to lattest update version.
I have tried installing each one of the files for a regular 335i w/o any upgrades.
Everytime I floor it to WOT my car spudders and goes in to limp mode...why?
No matter which MAP i use...my car still spudders...
I dont know what it could be...can you help?
I have an '08 335i sedan
can you tell me which ECU map to get..may be i'm using the wrong one.
also, map stage that is right for my car.
Thanks

You can only use STAGE 1 either Drive (shitty gas) , sport (91 octane) or Aggressive (93 octane).
The AP knows which ECU you have just connect it to your pc and check "Info"... pretty freaken easy.
Also read the codes for the issue you are having.... connect AP to OBD port and go to troubleshooting. Also take some time and read/learn about how AP works. There are lots of videos and docs on cobb site about it and tons of info here.

When I first bought the AP out the box and installed it to my car it felt like
a champ! It never spuddered. Then, after all the changes to the maps and version updates...I havent been able to get what I paid for.
I even have un-installed it and taken the car in to the dealer a couple of times
thinking there was something wrong with the car. But All that they did was regular
sceduled maintenance and a couple of changes like new spark plugs, coil packs, but
according to The Dealer...the car is in great shape.
So, I don't know what to do...may be I should take to car to Cobb now that they are
in SoCal...

Be sure that you are running the Stage 1 Sport map since you do not have DP's, intercooler, intake or exhaust. Cali gas requires that you run the sport map as the octane rating is lower than the aggressive map.

It sounds like you are having misfires which the usual suspects are plugs, coils, and injectors.

Plug your AP into your OBD II port and drive around. Go under troubleshooting, read codes and let us know what you find.

As everyone else said, make sure you are running the correct map for your car (sounds like stage 1). Let us know if you have any DTC's and we'll go from there.
