Just installed my V3 running Stage 1 aggressive. Car runs so smooth nice power delivery. Happy so far and looking to install charge pipe upgrade soon.

Tried to do some data logging for first time. Wanted to do more but with work and weather no go.

I love my PTF tune. Jake dialed it in for me without a problem using Cobb AP v3 purchased from them. The custom tune cut nearly 1/2 second off my 0-60 time compared to Cobb OTS Stage 1 Sport map. My car is a 2011 N55 E90 w/ 6AT and stock engine running on crappy California 91 octane pump gas. Need to do another round of tuning with my new FMIC as soon as the roads dry out here. Thanks, Jake!

CONs:
- Oil temp shows always the wrong values (told COBB about 4 month ago)

Browsing through the COBB website and it looks like they just made an update addressing the oil temp monitor.

Yep. Oil temp is fixed. Work perfect now.

Had these issues couple months ago and it was a sensor that BMW replaced, now I'm getting these issues again. I was driving on the freeway coasting at about 80.

Also I have been in contact with Cobb, and they let me know that they are longer doing development on the it's maps for BMW at lease for the E90. Kinda sucks as it definitely needs revisions.

[Jacblack]

I still get the code as well, I hate it! Really is my only complaint with Cobb. Reading this thread again it seems to be a DCT issue, the only problem is that I have a 6AT with the alpina flash and still get the code.

[jayzF30]

That's just an underboost code. Talk to PTF they can fix that unless its an actual boost leak. Have you boost leak tested it?

[Jacblack]

Yeah I'm leak free, its a random occurrence, not a constant. I could launch my car and go through all the gears and have no issue. But then I could be just coasting on the highway and just floor it and it will throw the code.

[CantCatchMe]

Anyone have any issues running Stage 1 FMIC aggressive? I'm noticing some days my car when coming to a complete stop my rpms dip instead of at 600, to about 500 like it wants to die. It did one time but hasn't since. No codes or anything. I'm thinking it might be the battery or boost leak, I'll check it out tomorrow evening. Anyone else have this issue?

[e90Nate]

can anyone help me, i currently have no maps on my cobb, i have no mods currently, about to install burger tuning intake, which ots map should i download? in the AP manager i have no maps listed

PROs:
- Easy-to-use
- Many Maps
- ProTune available (recommended)
- Code-Reading included
- Good Display
- Fast device

CONs:
- problems with power loss post shift on DCTs [fixed by Dzenno@PTF]
- 2C57 - Error Codes! [fixed by Dzenno@PTF]
- Oil temp shows always the wrong values (told COBB about 4 month ago)
- OTS Maps are just crap. Unusable. Sorry to say that
- Bad support

NEUTRAL:
- No control over VANOS-System
- No control over ValveTronic-System
- No control over VMAX. which makes me sick.
-> Neutral because not advertised. Still annoying, though.


More into Detail:
Problem with power loss post shift on DCTs
What do AFR problems post shift mean you might think. It's quite easy. The ECU enrichens the fuel mixture while we shift - we run too rich [EDITED: SPOOL-MODE WAS NOT THE ISSUE]. Therefore we loose power for more than 2 (TWO!!) seconds. So we shift, boost is building and for a total of 2 seconds there's just a huge drop in power. If we shift every 6 seconds we only have 4 seconds of full power (if we assume that full power is gained instantly after the 2 seconds). I was told that the issue is related to COBB and they have to fix it. Seems like they are working on it. Let's hope they fix it this year. There's no sense in upgrading the turbo if we aren't able to get full power with an ProTune. Same issue applies to all OTS Maps btw. Here's a screenshot. White line shows AFR, red line is RPM. Big thanks to PTF for their help btw.

For comparison here is an N54 Log. Same car, same tranny, same setup, also protuned - just N54 instead of N55:

LINK TO LOG: http://datazap.me/u/stanko89/log-3-4...9&zoom=188-379

EDIT:
Seems like Dzenno found a partial fix for this. The drop is still there but it doesn't occur as long and as much as before. We still need more research on this though.

LINK TO LOG: http://datazap.me/u/335iffm/cobb-n55...-15&zoom=4-496

2C57 - Error Codes:
Caused by a huge difference between the requested load and the actual load Users of the COBB AP get an 2C57 Error Code and the ECU will put itself into ERROR-MODE. As seen in the first screenshot in fifth gear the PSI start to rise for a short time and then drop completely. Then you'll see an 2C57 Error-Code on your APs Display. After you shift into next gear the requested and the actual load are nearly perfectly aligned. The ECU fixed it by itself but we won't be able to get full power after this. It just won't recover.

The reason why many non-German people won't ever get this code is that you most probably won't shift into 6th gear @ 5.600rpm because that's more than 200kph which is not allowed in your country. That's something COBB also has to fix. It occurs in OTS Maps as well as in ProTuned-Maps

Oil temp shows always the wrong values:
That's something many people told COBB month ago. They've just stated they'll fix it "sometime in a next release". NICE!. Still nothing. Seems like only 98F0B-Users are affected, though.

This short writeup contains a few things I thought you people should know. I've switched from JB4 to COBB for peace of mind. JB4 was without issues but I just don't like Piggybacks. Now that I've switched to the AP I've gotten a huge shitload of issues. Seems like that was a bad decision. I currently cannot recommend the COBB AP. I hope they'll fix it soon. And no, I won't sell my AP. It's a nice device the software just has to be fixed.


COBB! MOVE!


Best,
Manuel

It's funny but I'm running a jb4 G5 and have the same problem post shift. As soon as I shift I get a loss of power for about a second or 2, the car even jerks as if I'm letting off the throttle, meanwhile my foot is down the whole time. I'm starting to believe it's an issue with the jb4. Might go for a custom euro charged flash tune to see if it fixes the problem because they are local to me.. Looks like I'm not the only one suffering from this.

I have been using an APv2 for about a month now working on my tune. I am FBO on a 2011 xdrive 6mt e92. I based my work on the stage 2 aggressive + FMIC but I am far from that now. For starters, this OTS map was way too rich up top (which caused misfires) and occasionally made 20+ psi boost. I'm now sitting at about 17-18psi, with no rich misfires, and more timing. The car is pulling pretty good and the logs look relatively clean. It's really time to put it on a dyno so that I can refine the map more based on a known reference point (max hp/afr).

I guess my point is...the OTS maps need work before you run them and you will be logging...lots of logging. If you aren't prepared to to log and analyze/change in Access Tuner Race (or pay for a pro tune), don't buy a Cobb.

That said, I freakin love mine and the control it gives me over my own stuff.

[proTUNING Freaks]

We have sold these issues for many N55 cars at this point and should have no issues sorting this out for anyone else as long as you've got a Cobb AP on the car.

[CantCatchMe]

Okay so if I'm reading this right, P2C57 is caused by high revs(WOT) on OTS maps? I had it pop up when I was WOT from 3rd gear trying to data log.

Also, P387F popped up. What is that? No one seems to know.

387F= Power management, closed-circuit current violation.
The fault is recognized when the discharge from excessively high standby currents is higher than 1 Ah.Potential problem source(s):- Closed-circuit current too high.

Not sure if that helps.

I'm trying to understand what it means. Does it mean I need to charge my battery? I got my battery checked it said GOOD-Recharge, the battery needs to be at 720cca but mine was at 874cca. I'm hoping someone else will chime in on it.

[Rob_BMW_PNW]

Torn between wedge and ptf for my n55 dct for tuning via Cobb...
Any other suggestions reviews concerns 2 cents?

[stari335]

Try both and report back. I know PTF has done the most by far N55 wise just looking at this forum and others. Did you see their big turbo N55? Thing is running a massive Borg Warner EFR 9174 at 30psi without issues. Others struggle even on the OEM turbo.

Yeah might be leaning towards ptf for the same reason
Wedge is local to me but he said he's only done a few

Hard to find ones with a lot of experience

Ess is another option but that's a bench flash though they have a obd2 connector they say it 'might' work
Not really wanting to mail off the ecu

PTF's tune was very torquey when I rode in my friends E90. When I used my Wedge/BQ tuning maps(E50), it was very aggressive per request by me. Car ran very solid. You can't go wrong with either one.

[Rob_BMW_PNW]

Wedge is local to me, he said he did a few N55s to feel comfortable tuning them, I guess in person/dyno tunes we can address anything that comes up.

Car is hardly driven, wife drives to campus which is like 2 miles away and I am slowly turning it into a track car

[EB89]

Hey guys, I can see this is an old thread but there are some recent posts.

I have a JB4, I want to go flash only instead of a piggy back.

Is COBB usable with their OTS maps? I just want something I can flash and forget, dont care about high end features and logging or any other stuff, i just want to flash my FBO car and drive it, done.

Will COBB work? or do I need a pro tune? have COBB stopped N55 map updates?
