I have an auto and I also prefer the older maps from last Febuary. 2.03 feels so much more powerful on the unreliable butt Dyno. I never had any problems with 2.03. I hope the stage 2 maps will come with a similar throttle feel because I am getting downpipes this weekend and intercooler next week.

We are currently aware of a problem some users are having when updating their AccessPORT to Beta firmware. We are working hard to find a fix and we will update you with our progress!
At this time, I would recommend not updating your AccessPORT. Currently, there are no new releases that would affect the performance or safety of your vehicle of your vehicle, so beta updates are not needed. As always, if you have any questions, please send us a PM, email (tech@cobbtuning.com), or call (866-922-3059). Ian |

535i dyno
I'm a new (CPO'd) e60 535i owner. My question is, based on the dyno graphs shown on the COBB Tuning website, why are hp and tq #s between the 135i, 335i, and 535i all so different in stock form and as well AP tuned. To best of my knowledge, they are all running N54s, is that correct?
I did a pretty through search on this froum and read thru 50+ pages and didnt find an answer. did i miss something? |

That had crossed my mind...but i was always under the impression weight and size would have a more direct affect on the ultimate performance of the vehicle (say 0-60 or 1/4mi) and not necesarily direct engine output. Am I wrong? |

Short answer is there is very little difference, and the major reason was that car had hardware issues (wastegates IIRC) that caused it to do badly, and they've not had time to do another dyno with another 535. |

There are some differences in the car. The engine itself may very well be the same but the 535i has different DP's, different exhaust and a different FMIC then the 1 and 3 series. The first Cobb dyno with a 535 did indeed have an issue but even when it was rectified, it is a slightly lower number (10-15 hp) then the 335's.

Found my thread also: http://www.e90post.com/forums/showthread.php?t=483122 The exhaust isn't an issue at stage 1, at least they didn't indicate it. On the 335, the exhaust isn't a requirement even for stage 2 or 2+, so I can't see the one for the 535 causing issues in stage 1. From the main coding dude himself: Quote:

The low run is bone stock (cobb completely removed). The high run is stg1 v301 aggressive. I can confirm (finding parts) that the 335 FMIC, DP's and exhaust systems are all different then the 335's. While I cannot say if it makes a difference, I have heard from a few different sources (manufacturers) that at least the FMIC for the 5 is smaller then the 3.

what u said makes sense. altho no one has confirmed that the 335s have diff exhaust, etc. they just sound different from 535s. xclone, i see that you have a 535 as well. can i ask your first impression (and 2nd and 3rd) of the AP when your car was stock (assuming it was). i dont plan on doing much else but maybe springs and strut bar, nothing in terms of CAI or exhaust. |

My first impression of the cobb? Trying be honest here - it almost made me pee my pants a little. You wont really notice anything at low throttle, but when you go WOT, and you hit the boost, it will probably scare you just a bit (in a good way) if you arent used to something with that amount of HP. For my parameters (not wanting to be under the hood wiring things up) and ease of logging, install - it was the perfect choice!

I get the same P30FF code on 3rd at 6300-6500 RPM, I've checked just about all connections I can think of as well. This is on Stg2+FMCI Aggressive, I hit target just fine, no issues building boos, it only happens on 3rd (haven't really maxed out 4th) around that Rev range. Cobb is looking at it though and they haven't ruled out a tune issue yet.
