Cobb: Any chance of disabling the underboost codes so that we can simply bypass the stock boost control system? Set it @ 18 or 20 psi or whatever in the DME and then use an EBC to control boost? The DME would still respond to the actual boost (just like it does if you underboost currently) but if it just didn't code/limp then it would enable the EBC usage with external wastegates etc.

There's more to it than just the 30FF code. The DME will also probably throw a 30FC code for "wastegate control." However, i have no idea how much coding and logic reworking is required to that so that actually might be a possible workaround.

Yea I'm thinking more along the lines of "disable/bypass the entire boost control system" and then see what codes pop up, and go from there.

Of course, it may also be possible to just use an EWG and spend a lot of time working backwards dialing in the requested load to the actual boost. Unfortunately, in that situation you still have the DME complaining about the WGs not reacting to it's requests.

The other thing I was thinking about is the DME requests different boost based on throttle position so trying to go say 50% throttle (depending on your map, of course) and it requests half boost, which is totally possible with full DME control of the wastegates, would crap out if an ordinary EBC let the turbos spool up fully like they would. Hmmm... |

Ordered the COBB AP for my 2010 335XI yesterday. Good news it will be here tomorrow. Bad news is I paid 130.00 for priority shipping. (I'm very impatient).
I'm sure Stage 2 will be right around the corner. Quick question. Did I completely waste my money buying the aFe Cold Air intake system (Stage-2, Magnum FORCE PRO 5R 54-11472)? Seems from everything that I read it's a complete waste of money. |

When you install/uninstall Cobb, does this also reset engine adaptations at the same time, or do you have to do this manually?
Conversely, when you re-install Cobb after a dealer visit, do you have to wait for re-adaptation to take place? |

Create a .zip folder and then copy the log into the folder and attach that.

Thank you. Everything I've read so far about the Helix is extremely positive. Gonna buy one ASAP. Will installing a FMIC void my warranty? not only do I have a CPO car, but they also through in a 5 year 100K full BMW warranty for free. and its nice to know I will have brakes, rotors, services etc covered. I received my Cobb AP yesterday and flashed my car with the stage 1+ aggressive map. No issues, no error codes. All I have to say is WOW! So far it has exceeded every expectation I had. The gains are VERY noticable. The car is a beast and I really like the aggressive map. And trust me, I dont get impressed easily. I driven or been in some of the fastest cars or boats there are. My brother owned a ruf twin turbo and recently sold his Heffner lambo gallardo that dyno'd at 1135HP. (That car was disturbing) If anyone is on the fence deciding if they should spend the money on the Cobb AP I'd say absolutely positively YES. I was so close to going with Dinan again, but I'm SO glad I didn't. It's been a long time since I owned my 2002 M3 that I Dinan badged. I know this is gonna sound crazy, But this car seems faster and I didn't have to spend close to 10K on parts! The only draw back is I keep looking at my speedometer and saying "damn it! I'm doing over 100 again?" The car just wants to keep going. This simple little mod is going to get me in serious trouble. Can't wait for stage 2. :-) Gonna install the intake today for the hell of it. (Though something tells me i should return it and put the money towards a fmic. ) Thanks everyone for all your insite and knowledge. It's paid off immensely Christian

Please check my logs
Please check my logs. Stage 1+ Aggressive w/ 93 octane Shell. New plugs and injectors. 49xxx mi. Seeing timing correction of -4 on cylinder 4 and -3 on cylinder 6 when I shift into 3rd gear. On a prior pull I saw correction on cylinder 5, so it's not consistently the same cylinder.
If I am seeing sporadic corrections of -3 to -4 on one or two cylinders, and usually different cylinders, am I ok to stay at stage 1+ aggressive? Thanks |
