DP with AP
Slops' video clip shows really nice smoothness in the acceleration with the AP. I did notice the SES light on, resulting from his DP.
I have a couple of questions for Cobb regarding DPs and upcoming Stage 2 maps on the N55 -- since I'll definitely want to be able to run Stage 2. First, is a DP definitely required to run the Stage 2 maps? Is the answer the same for RWD and XI cars? The XI has secondary cats in back of the DP, whereas my RWD car has cats only in the DP, and I am reluctant to get an aftermarket DP. (Note: I already have FMIC, chargepipe and drop-in filter on my car). If better exhaust flow is essential, could an aftermarket exhaust be an alternative to a DP, would that help much for a RWD car? Second, are there any future plans for the AP to eliminate the SES light when running a DP? Thanks.

Secondary cats on the XI has no affect on your O2 sensors since your sensors are way upstream... those additional two does nothing for the car other than added restriction in the exhausts. So your answer will be the same for xi and rwd cars.

Does it have effect on the loudness of the car with catless dps?

They updated it at Cobb while I was there. I'm assuming the guys checked the beta box? But I'll try it anyways

Really hoping that Rob sees this because Neil said he could submit my ROM info to him, but he was pretty sure that they are on vacation until after the new year.

You know what? I didnt even realize, i thought the cobb stage 1 was on top and stock on bottom. oups. if you could flash to stock and do a run, and do a stage 1 run, I can put together the video for comparison. I also think the stock n55 video i pulled was from a rwd not xi. all things said with rain etc, the stage 1 looks promising... |

I have PPK and took a video.. Compared it to a Cobb stage 1 N54 video on YouTube and to 100km/hr they are similar if not identical. This is where it Cobb takes over, by the time my speedo was at 180km(approx 1/4 mole) Cobb was hitting 195km.
When comparing tunes the real difference is 100+ speeds. When comparing speed differences they should be upto 180km/hr and not just past 100 as its difficult to judge.. The difference will be seen past these speeds!! Last edited by Tricki; 12-24-2012 at 08:09 AM.. |

1) What are your thoughts on running the Aggressive mapping with California (and NV/AZ) 91 octane while doing data logging? For those of us living in CA, this will be our first question. 2) Do you believe that the Sport mapping is similar to PPK? Thank you! |

If you can use an ATM you can do the install. It's that easy. It takes about 20min, but that is just waiting to download and save your original map and upload the Cobb replacements. Super easy

Using the forums are more complicated. There's a video on COBB's website on how to install the AP on a BMW (it's for the N54, but the process is the same). |

If people are that desperate to run Aggressive Maps, I will say that even here in NJ (running 93 octane), I would see the occasional, concerning timing correction. To eliminate that concern, I'd mix in a gallon or 2 of E85 to bump up the octane & let the tune rune happy |
