Theres not much difference between S1 and S2 (no fmic) other than .5 to 1 degree in advance = around 5-10whp more. S2 sport is weaker than S1 aggressive.
S2+FMIC is a different story and only for FBO guys.

Hopefully the new maps are released before the end of the week. Seems like a lot of us are having these misfires and hopefully the maps take care of it. If not, it may be time to take care of the carbon build up now that I'm at 45k miles.

I dunno, those seem like pretty large timing corrections for just rising IATs. On stage 1 I've done pulls hitting 160F and it never dropped timing that many degrees. I'm assuming it happens at that point in 4th and not 3rd because engine load is higher (especially air resistance) at that point and peak power is there. Going uphill increases load further. Maybe you should call Cobb or PM Rob and ask what they think timing pulls could be caused by?

I e-mailed Rob with the raw datalog file and he got back to me very quickly. He said that the timing is likely caused by bad gas and he recommended I try a different gas station and use the Sport map in the mean time (says the ECU is protecting the engine well, but he likes to be cautious).

And since I'm already past 50k miles, he is recommending I get my intake valves cleaned because I probably have a lot of carbon build-up at this point... I'm going to look for a place to get it done... just a funny story, I called Bloomfield BMW last week about intake cleaning and the SA didn't know what I was talking about... he kept thinking I was talking about "Injection cleaning" and said that BMW recommends against it on our cars because of high pressure something something. Guess I'll have to call a different dealership lol...

Revised stage 1 mapping should be out sometime next week with a bit of a power bump. Purchasing a FMIC to run out stage 1+FMIC mapping will certainly get you a good bit of added power.

For anyone with misfirest please do contact us so we may help you fix them.

Misfires are usually a mechanical issue that needs to be taken care of via a sprucing of the ignition system. Otherwise power must be reduced to a level the ailing ignition system can handle. This can be completed by running the drive or sport mapping. We would rather help everyone fix the ignition system than run a less powerful map.

Check out the second episode of "Ask COBB":
http://www.cobbtuning.com/Ask-COBB-s/70714.htm
[u2b]http://youtu.be/FsNK1ySAlSo[/u2b]


Our revised mapping and new stage 1+FMIC will add power.

Cheers,
Rob

I think there's a TSB about intake cleaning, maybe you can point your SA to it. Let me know what happens with that and the gas though!

Stage 1 and Stage 2 will be revise to be smoother while adding more power. Stage 2+FMIC will be revised to be smoother. Stage 1+FMIC will be all new.

Race mapping is something I am targeting to be out by the end of March in BETA form. This will be for use with "pump" race fuel and/or those with meth. We will not have a safety mechanism built in for flow failures, however the timing being run is not as aggressive as other tunes out there.

Rob

not squeezing any more power out of the stg 2+FMIC agressive maps? not much more to be had there i guess...

Been enjoying my cobb for a couple months now and i was wondering if cobb could make a N/A(naturally assperated) map to be added alongside valet and stage 0 maps. i only wonder because I (I'm sure im not alone) make long distance trips on the highway and am not always looking to get the max performance out of the car. A N/A map will help increase milage during a long tedious drive. just some food for thought otherwise Cobb u have a VERY VERY satisfied customer.

Plenty of people are doing that to good results. 33% E85, 67% pump.

I just purchased my 335i with an aftermarket FMIC in December, pulled the trigger on the Cobb AccessPort last month, now a new stage 1 FMIC map! Life is good!

Boo to Arizona crappy gas though.

I'd dig into what changes they made for the E85 on other platforms and when ATR comes out, tweak the OTS maps on a dyno little by little until the car tells you to back it off... IF they don't come out with an OTS E85 map.

-edit I personally know someone running the 2:1 mix and made some impressive power on the stage 1 aggressive map.

I was under the assumption that the stage 2+ maps would be smoother and have more power. I am a little upset that they will not. I was hoping to get the XI into the 11's
