I assume you mean for dealer service? I try to drive around a bit after removing the flash to see if any adaptations take place, but TBH I've taken my car in within 20 miles of taking Cobb off, and it was fine. No warranty issues no questions.

Just started pulling logs from my car, flashed it about 2 weeks ago.. Had some misfires from overdue plugs.. just did them this weekend.. and there was still a slight hesitation in boost, i figured it might be more than just plugs.
Anyone want to take a look at this log for me? It seems the car is pulling timing? Suggestions? |

+1 to all of this. You're turbos are hitting targets just fine, your corrections are fairly severe and that's what's causing the lack of performance. |

I would recommend running maybe half a tank of 91 once a month just as a preventative measure. In all honesty, you can probably run e30 all the time and it not hurt anything. I just like a little peace of mind, especially when it's so easy.

I'm not getting any codes or anything. The car was fine before. I had a misfire on #5, so I replaced all the plugs with bosch plugs and I swapped #5 coil with #1 coil. I'm going to maybe try stage 0 and see if it does anything weird. I'm running FBO. |

Continue to try less aggressive mapping, and/or add a bit of E85 to see if that smooths out your timing issues. Also log more of the pull, ideally you want to be looking at 2.5k-6.5k with zero throttle closures.

sounds good thanks! If I were to upgrade the LPFP, then I wouldn't have to run 91 once in a while?

However, what I'm talking about with running 91 is CLEANING the fuel system. E85 has a reputation for leaving deposits on injectors and gasoline has been a used as cleaner to help clear this deposit up. However, this has always been on port injection setups and I haven't seen anyone mention this buildup yet on our DI setup. Check this discussion out. It's talking about the 2.4 SRT-4 engines, but I've seen similar discussions on STi and DSM forums. http://www.srtforums.com/forums/f187/e85-black-goo-formation-injectors-634529/ |

Ordered Cobb n54 AP today. Can't wait to receive it. Making the switch from procede.
What's the difference between linear and stock throttle? I'm FBO (dp, fmic, cai, cbe) but no meth. Safe to run stage 2 aggressive?

LT attempts to replicate a more naturally aspirated type response, just try the two and see which one you prefer. And if you're FBO stg2+ are the maps you'll want to run, or E30/race maps if that's what you're looking for.

Linear 1) single throttle position. Rpm engine speed increasing or decreasing. Load requested stays constant even as revs rise. Will feel as constant acceleration as revs rise (excluding frictional and aerodynamics and .5 m v square effects) 2) throttle position increased or decreased for a given rpm. Load requested change matches change in throttle in linear fashion for all speeds. Wool probably feel like your foot is more connected to throttle valves (know they don't exist) Stock 1) single throttle position. Rpm speed increasing or decreasing Load requested high at low rpm, tails off as rpm raises. Gives impression of immediate boost to almost obtain a requested rpm. torque then tails off as requested rpm reached. More throttle needed to maintain load as speed rises. 2) throttle position increasing or decreasing for a given rpm. Load requested slow to respond initially, peaks rapidly, then flattens out again. Feels that low request artificially surpressed to aid smooth driving. mid throttle is boosted, last throttle position fine tunes somewhere around maximum. Flame suit on. Lol |

and um..... Safe to Run S2+ AGG. Based on NYC having 93 octane. I am sure you will like ST. Also try the E30 MAPs, you will never go back. Do you have access to E85 pump? ( http://www.e90post.com/forums/showthread.php?t=738596 ) always log to be sure, log after a few WOT to ensure the car has adapted all the way. a good read on how to data log with COBB. http://www.e90post.com/forums/showthread.php?t=696472 be safe!

Do I have a problem with 1st and 4th Cylinder since timing is being pulled at WOT, other cylinders pull timing but in certain instances and under normal driving conditions. I'm Running Stage1_ST_Sport map on my 335i e92 Stick just with K&N Drop In filter on 93 Octane. Just installed it 2nd day 2nd drive about 10miles long. I didn't notice any hesitation in acceleration and I also had DTC ON and TCS ON don't know if it matters or not. Car year 2008 and has 26K miles on it.
