3) If I have catless downpipes will it clear the o2 sensor codes (like JB4 auto clear?)
4) Is Accessport now available for my tuner?
5) Do they have the ability to add multiple maps? How many? Switch on the go? (it just says it takes minutes)
6) What is the best map for DCI, DPs, Charge Pipe/FOrge DV's, and FMIC?
7) Is there a special map I need to use or any extra things I will need to use E85? Or can I just fill up with E85 and set it to my FBO map?
8) Does this work with MAC OSX? or If anything will it work fine in Parallels?

Thanks guys.
You don't need to go through all 380 pages

Just go to the Cobb website. If you can't figure all this out from there, then maybe you shouldn't be doing anything

29E1 fuel mixture control 2, and P2AAF fuel pumpe, plausibility. The car did kick a SES light at one point but no limp mode. I was running low on fuel so I cleared the codes and filled up with a quarter tank left with shell 91 and switched maps back to Stage 2 +. The P2AAAF code never came back but the 29E0 and 29E1 keep returning even after the 2nd full tank of 91. I do have UR catted downpipes which never threw a code after I installed them on the car stock before I got a tune. A buddy of mine said the E85 could have killed the cats which is why I'm getting the codes now. Ive read these are the codes you get when you go with cat-less downpipes. The car runs and pulls great LPFP is in range not sure what else to check. If this is a cat-less down pipe code I'm gonna ditch these UR catted down pipes and just go cat-less.
I am running cP-e downpipes with highflow catts. I have ran E50 on the OTS E30 map and never gotten a fuel mixture fault

Btw you will never be on target when fuel mixing cause E85 is never exactly E85. Mixing a bit over E30 ie E34 as your did is ideal.

I am not saying to run E40-E50 running an E30 map. However you can run between E30-E40 on an E30 OTS map. Why your car spit that fault is weird, you might want to raise your Fuel Scalar to E35 calculation

The catts have nothing to do with that fault code, it could be also your O2 sensor going bad. I have been running E85 for almost 1.5+ years, and now stock and no codes

Thank you. I will defiantly look at the fuel scalars as well next time I run the E30 maps. I was also thinking maybe I strained the lpfp? I will try doing some hard pulls and logging the fuel pressure. I will also look at finding a way to test the o2 sensors. Thanks for the pointers

Had another question. You mentioned it could be the o2 sensors going bad? Im thinking you're talking about the pre cat sensors? I Thinking that could be the issue i changed the post cat o2 sensors a year ago and the pre cat are factory originals my car is an 07.

SERVICE ENGINE SOON light

Sorry in advance for the rookie Cobb questions.....

Just got an aftermarket battery installed in my 2007 335i after getting advice from the forums here.

http://shop.advanceautoparts.com/web...___#fragment-2

All seems fine, but the tech must have touched something as my cluster fuse was blown post-battery install and had to be replaced. And now my 'SERVICE ENGINE SOON' light is on.

1. Any insight/advice on how a new aftermarket battery (or blown fuse) would cause this?

2. Can I use my Cobb AP to check to see what code is causing the light to be on?

3. And can I clear it with my Cobb?

4. Finally, should I 'register' the battery with the car? I heard advice both yea and nay....

That answer referred to 2-4. Plug in Cobb ap, click troubleshoot menu, read codes or clear codes. It's really simple.

kewl, I'll give it a try.

you feel strongly about 'registering' an aftermarket battery? It comes with a 3yr warranty anyways..... What am I really in danger of?

Seems silly to pay 85 bucks to register it at dealer (wish I could do the registering with the Cobb).

Once you become facile with the Cobb, the next level is INPA and a K+DCAN cable, which I believe will do the battery registration (somebody please check this).

Hi,

been on stage 1 + for quite a time now. I am thinking of doing an exhuast mod and while i am at it, i am thinking if getting the secondary cat delete. It will be cut and weld a new pipe on. Would you recommend to run stage 2 map since i got 2 of 4 cats off? or it's a nono since the restriction is still applied too close to the turbo?

Stg2 maps with OE downpipes in place is



Oh no no list.


Don't do it, egts will get too hot and things will go south from there. Anyways, the Stg1+ maps you're running right now are stronger. So there's no point.

This is a response to track this issue.

All Fuel Injectors were replaced by BMW once I noted that at cold start the car sounded rough. I had no miss-fire codes either, but that diagnoses was there. The car had Mixture Control Code also, this lead them to believe all injectors had to be replaced.

As part of the service they also replaced the spark plugs during warranty procedure.

It took an additional 6k miles for the problem to be noticeable enough in Stage 0 from code coming up in Stage 2+ for reference.

I just got the Cobb V3 about a week ago, and flashed Stage 1 Sport maps to the car.

Could some one take a look at my log and let me know how it looks? I'm pretty new at this but I'm learning it slowly. The log was taken in 3rd gear with a little bit of 4th gear as well, 91 octane. Link: http://datazap.me/u/mycarhasredwheel...little-bit-4th

If I'm correct, It looks like it is overshooting the boost targets in some places pretty badly, which is causing throttle closures. The car has brand new turbos on it, with about 2,000 miles on them, so that I'm assuming thats why.

I am not sure about the rest of the log though. If someone could take a look at it and let me know I would appreciate it!

I have seen cars blow up on dyno lately and after that I changed my mind and went with P and L. I let you know after 11th of Nov.

Anyway I really need to learn how to do this tuning my self but not on my car LOL.
OK Got my tune at P and L, they flew in a guy that goes by "Junior" and he spent a good amount of time tuning my car. I didn't want anything that would blow my engine anytime soon and wanted a good map for the track, constant abuse of the turbos and engine, and also good for daily driving. Reliability / Consistency and no timing pull was #1 for me so thats what he tuned my car for. The result for my 93 Octane map is 380 HP to the wheels and 423 Torque. He did about a dozen pulls and constant power results. All the torque kicks in at around 2300 RPM all the way up to 6500 RPM as I wanted . So when i shift i'm always in max power band. You can't beat that. I have reached my goal and some. My main goal was to get more out of this then Stock e92 M3 + some and thats exactly what I got. e92 M3 stock is about 345 HP to the wheels and a lot less torque + add 200 lbs extra on car weight. In addition to the tune, my throttle sensitivity was programmed to be between ST and LT throttle and it is perfect. You can now modulate the throttle better which = better control. Highly recommend Junior he really knows his stuff and P and L Motorsports they are really cool people go and you won't be disappointed. Oh ya price was $650 but I think it's well worth it considering that your engine is the most pricy part of the car.

PEACE! Now off to my e46 M3 project .........

help with codes

Hello , so im ripping it on the road yesterday racing the new 640 4door,
and all of a sudden my car service engine soon light came on just blinking ,
pulled over and checked the codes
im running the e30 map

P30BB ( injector, power level 2 )
P29D1 ( misfire, cylinder 5 )
P29D2 ( misfire, cylinder 6 )
P29D2 ( misfire, cylinder 4 )
P29CC ( misfire, MORE cylinders )

yesterday i also got a few more .. .i dont recall what they were
i know it was lambda something, about catalytic converter
and i also got one about a boost leak ,

i freaked out and reset the codes and changed the map back to stock to see if it would remedy things, .. now the codes above is all im getting

engine sakes really bad, and exhaust is giving a baffling sound

anyone can help me as to where to start with this ?
im running the NGKs 1step colder for over 3 months with 0 issues the car runs amazing with them, and changed one of the coils , thus far
ive checked the charge pipe, vacuum hoses , didn't see anything with the naked eye, but was just a quick scan ,
also there's no black smoke, grey, white or blue smoke coming out the exhaust,
im hoping its somethign simple like the HPFP or an injector or 2...but
would 1 or 2 bad injectors really cause misfire in all cylinders, ?
and if it was the HPFP ..wouldn't i get a code about it ? ..the car starts
so its getting fuel, but what im assuming is perhaps its not getting enough fuel ?

What is the age of your ignition components?

Log it and post that and the accompanying codes. Well don't log if you think it is truly dangerous to do so, misfires feel like the world is going to end but they're not a BIG deal in and of themselves.

plugs are brand new, there have been a few coils changed when it was under warranty dont recall any injectors being chagned, but everything is pretty much life of the car so far, its 07 and has 68k miles,
lol im honestly scared to mess up anything else, does it need to be a WOT log? i took it out for a little drive this AM to see if it will throw any more codes, but i didnt get on it .. prob about 15mph at most


i found this http://www.n54tech.com/forums/showth...d=1#post289028

which is pretty much the same predicament im in , however.. changing DME for something liek this i sure hope was a bit excessive,

i have the BMS o2 sensor fix piggybacking on the DME, when i just had downpipes installed ... now that i have the COBB, i know its not needed, but i havnt taken it out anyone know if that will throw codes on the COBB
?

Wait you have DPfix in? Take it out now. Duh. It causes some strange adaptations and biasing if you DD with it. Your trims are likely wacky.
