Going to swap coils by next week since my spark plugs are brand new. If misfire follows then I'm going in for warranty replacement. If not coils - its injectors. If not injectors..umm fuel pump. So far my limp is due to misfire on 6th at 6k near redline. Otherwise, safe ds gear shifts occur mainly under 10 psi. After trial and error I am convinced it is hardware.

So in cooler weather, your psi will be a little lower.....therefore less likely to blow out the spark plug |

Like shiv said, this is a beta map. He may need to make adjustments on it! |

The question is, do you limp on the 9-9 Stage 1 map? We have 1 confirmed person running stage 1 9-9 and not having issues. My car's getting an alignment right now but i'm trying this tonight to see if it limps out or not.

Help clarify this for me. So if I don't limp on Stage 1 on 9-9..what does that mean? Because I already limp on Stage 3 (7-29) AND (9-9)beta which leads me to believe a hardware can't handle that much boost. Wouldn't that just add to saying I can only run on low boost maps or valet - making beta irrelevant?
I have misfire 6 near redline and 2E9F code. Are you able to run stage 3 yet? Curious if you get the same results on higher stage. I'll run Stage 1 9-9 tonight with default settings except 02 sim 80% and will keep you updated. |

Like I said guys, the 9-9 maps were specifically designed for 6MTs. They have worked fine on the vast majority of 6ATs that have run them. But they are more aggressive at the shift point in terms of boost pressure. Which is why everyone likes them.
However, if your car doesn't like the beta maps, go back to the nonbeta maps and enjoy driving. If, for some reason, the older maps cause misfire up top, go through and check your hardware (spark plugs&coils) because there are hundreds of 6ATs using those maps without any issues whatsoever. Shiv |

I had the same symptoms as you, and for me, it was the HPFP.

I am an auto, and I have no probs since installing the 9-9-9 maps. My mods in my sig, running 80% UT 100% ign.
I triggered limp mode once last night on a 1/4 mile run at Infineon using 96oct 85% UT 100% ign. It was the same auto-kickdown issue on WOT, DS limp mode mentioned at the beginning of this thread. My error code was: P1121 Pedal Position 1 Range/Performance Problem I cleared it, lowered UT to 80% 100% ign, and made sure I never hit kick-down again. I ran fine the rest of the night going WOT using both DS and manual shifting. So no issues here. I had a brief issue on the 7-29 maps in this thread: http://www.e90post.com/forums/showthread.php?t=295953 Consulting w/ Shiv and Dustin, we chalked it up to a random occurence of 100F temps and maybe a bad tank of gas. I had no FMIC back then, so my guess is the 100F temps. No problems since then. I was just paranoid back then because I just replaced my HPFP. Sorry, I never had the same probs as you guys, but hope my AT input helps. Quote:

I just came back from testing. 9-9 Stage 1 defaults, (70% UT 100%ign) not problems on my car tonight. Temps are cooler though I was a bit annoyed though... I was testing (logging) the stage 2 map and a 996 turbo showed up so my driver decided to take him on. We did great (though the 996 driver needed a lesson on how to launch) but we were infront by a car and stayed there but we couldn't go higher speeds. The issue was that my driver didn't look down fast enough and just past 6000rpm, WHAM..... limp mode... I read about all this MT records being broken and kicking ass and being faster than the auto's but my auto doesnt seem to run.... I think i may have to see what else is available until this is all sorted out... I want fast and i want fast right now |

This would explain why stage 1 works fine for most of us! Actually talked to a buddy right now and he has a 335 with JB3 on it. He's willing to swap tunes with me to see if the problem follows. Shiv says the maps were designed for a manual but auto's are running it fine without issues but before he said it must be the car, (plugs and or coil) I went out and bought a set of plugs and up here in Canada (we have the up the a_s tax) so plugs cost $25 each plus 12% tax so costly. I also ended up picking up another coil as a just in case thing and that ran me another $75 plus tax... So for the price of a set of plugs and a coil, i could almost have another tune While i do agree that most times, it's the user, in my case it would have been nice to know that the map was geared more for the manuals....I read through the entire 9-9 map thread and no where did it mention it was tuned for a MT but may work on an auto. I did all this testing, and i can honestly say, i really doubt its my car.. I kept thinking it was more an auto map as there was a MT Bog fix coming out right after for the manuals... oh well... rant over... |

I'm running Stg 2 defaults now UT 80% Ign 100%, but set my overboost limit to 18psi.
Prior to FMIC, Stg 1 75% UT Ign ??% was the best I can do. It bogged down at 80% UT 100% Ign (very noticeable reduction....acceleration feeling became smooth instead of aggressive). On the street, I also run fine at Stg 2 UT 85% Ign 100%, but I keep that on my map switcher. It's always cool to run a little less than max potential so you can feel a little more kick when your by-the-butt dyno gets used to the new power. Once I validate that 85% UT is reliable, I will dial back and run every day at 75% w/ a 'power' mode of 85% UT. I think it's cool to mimic a 'power' button feature that's present in many cars and you really need a 10% UT change to feel a noticeable difference by-the-butt (5% change just feels like it's running a bit stronger. Lastly, I'm glad I can run at least 80% UT cuz I'm so not an exhaust person, and was afraid I'd be too 'restricted' w/o aftermarket exhaust. My car is an excellent sleeper.

True that Shiv. Ever since you retuned that night (which btw Shiv is flippin awesome, to look at my car for free and clear out my codes and just go on some test runs and just man idk what to say other than definitely best 1st time experience with tuning a car for my first time 'btw I think I might know somebody for that thing you are looking for ') my chip I haven't had any misfires...like you said the issue probably is the spark plugs...I'm making sure I stay under 5500 to 6000 rpm when changing gears...but last night I down shifted a lil quick and almost tapped 7000rpm lol...I quickly up-shifted and the car was okay.
I've been looking for OEM Bosch spark plugs, best price is $14 for each @ local bay area shop (if it works out I will post that info or PM me- if you know someplace cheaper let me know)...but I am going to need to buy the tool for the spark plugs which is the remaining issue before I replace my current ones, I'm still searching for that one. So far only saw one on Tischer bmw's website for $60. FYI...I'm currently at like 24,500 miles with original Spark plugs. Quote:

Found out the plastic boost line to my turbos was causing leak in addition to my limp. Still going to dealership for misfire but I was shifting fine today at 12psi.

Limp is fixed. I went to change suspension on vehicle. When it was lifted with heatshield off noticed light oil pouring out of the boost pipe(plastic) near turbo and dp entry. So pretty much a boost leak - pipe was stressed at connection. Tech pushed it back in and I have been limp free and hitting 16lbs. Fix might be temporary so I don't want to expect too much but...hitting 16..its been a long time since I've seen that number. Still going to dealership to make sure all is good. I will probably do a log run in the next couple days to confirm this. Hope this helps.
