Flashed v401 stage2+ Sport ST, ran out and did 2 quick logs... probably not 100% accurate since my ecu hasn't completely had time to adjust. Cyl 4 is pulling a little timing for a split second, had that before but that went away after a day. For some reason, I couldn't get it to log properly, it would either drop off the front end or the back end of the pull. Both pulls were in 4th gear.

On a side note, the HPF FMIC is keeping the air temp at a decent temp... it was 80 out today and temps stayed nice and even, car felt good. I'll also record my cold start with v401 tomorrow... when I started it after sitting for a few hours, I didn't hear the WG rattle... hoping for the same success in the morning |

Before I changed the spark plugs 2 and 5 were the noisiest. Now timing is perfect on all cylinders.

I gave aggressive some more time to adapt and got another pull in last night and compared the two runs. i started out higher in the revs on aggressive than i did on sport so the beginning of the graph is misleading. It's raining now so i won't get to log again until tomorrow(hopefully.)
Aggresive and sport seem to make similar HP but aggressive has noticeably more torque. |

Just went for a ride in a car with a Cobb unit installed. I was pretty impressed. They were running the 4.01 maps w/ stock like throttle. The car moves pretty good. Full bolt ons.
We only have 92 octane so they were running the street maps, not the aggressive maps. The aggressive called for 93. The customer wanted to be safe, so he used the street names. Anyone running aggressive on 92? Michael |

yesterday with my AT Stage2+fmic v401 Sport LT map.
did wot with AT at Drive -mode ->no errors,acceleration very nice BUT when AT at Sport-mode,no errors,but think something happened just before shifting to bigger gear ,at around 7000rpm.will take logs today and sent those to cobb. maybe shiftpoint is too high for tranny ...or cant handle torque at around 7000rpm, or something else...well ...have to find out what.i am using 98 octane . |

I have heard that 98 octane in other countries is only comparable to 91 or 93 in the US...maybe you just don't meet the requirements for Sport?

yes, that shoudnt be the problem.98RON i use should be more than enough for Sport map.Aggressive needs 98RON,but i dont use aggressive map.
And quality here in Finland, shouldnt be a problem,would be another story if i would go to Russia have: ETS 5" FMIC BMS Dual Cones 4x86mm back exhaust Cp-e Cattless dp´s there is no way that it doesnt meet the requirements for Stg2+FMIC Sport map. Skinrock...so you have Stafe2+FMIC and AT too? did you investigate further why it did so when AT at Sport-driving mode and not with Drive-mode? sent logs to cobb?

Yes, I'm 2+. No, I haven't really had time to debug it and send them logs. I don't really push it that much to be honest, I just want something stable that makes me smile when I ask for power. Drive has been good to me in that regards, and I am planning on just getting a custom tune when a local shop gets ATP support. I assumed it was because Sport is not designed for my "91", but it sounds like there is something with AT in general.

now I'm FBO, but haven't tried the stage 2+ agg yet. As rader mentioned, logs should tell us whether it's OK or not. Once I break in my clutch, I will try some stage 2+ agg pulls

great! i think with Cobb AP tuning i broke my 335i AT
Car shakes and rumbles in normal driving.this happened first time ever, after did the logging :/ = fast accelerations. didnt rumble at all after the accelerations,even when cruising at slow speed to home...only after started car next time...then its like rumbling... just terrified ---- continues: i cleared the DTC codes..car ran 100m ok then shaking again and barely 100m back to home.now with codes: P29DC Cylinder Injection Shutdown (this was only error after first time car started to shake) P29F2 High-Pressure fuel system,fuel pressure P2FBF Fuel pressure after release of the injection seems that car starts hardly like in youtube video: http://www.youtube.com/watch?v=ieIe3pkXa4M just hope it is just the HPFP and hope its in BMW´s Warranty in europe too like in USA 200 000km / 10y. ---- UPDATE 26.3.: car dealer said first they will update the ecu, said that it propably wont fix the hpfp issue, but is mandatory update,related to hpfp Last edited by paapaa; 03-26-2012 at 06:54 AM..
