quick question- may someone explain to me how to use the cobb ap as a boost gauge?
I dont usually keep it plugged in while driving- but I gave it a try and I dont know if I used the right setting- as theres a lot of boost options under live logging. whatever one I choose- it seemed to start at 14.7 and go up to 21 PSI- so I dont think im doing it right. |

I assume you tried changing coil packs?

More aggresive = more of a chance to misfire. Change plugs around and see if misfire follows...

Hey guys, I just got my AP today for my '07 335i. I am running stg 1 aggressive, linear throttle w/ injen intake as my only mod. I drove around for probably 25 miles and realized I am getting some kind of stuttering while accelerating in the higher RMP range. It feels like the car is turning back the gas because of traction loss but I was not having traction issues and dtc was partially off. Overall, acceleration is not very smooth; I am getting variations in acceleration with a steady increase in throttle, almost like the car is choking or something.
Any ideas? |

From what i've read you're right about the P2AAF code, but i've never got that code. I've been running the Cobb tune for months(and thousands of miles) with zero issues; except for having to change the plugs to run stage 2+ but thats the plugs fault, not the tune's. |

Yep, i don't know if it's "adapting" per say, but it definitely gets better after having some time to learn what's going on. I've seen several people have the same experience with flashes. I assume it's doing the same thing the stock DME does when it learns it's adaptions, but since there is so much more power it's more obvious when it's learning.

The ECU needs always adaptation.

hey guys...i recently installed my downpipes and changed maps to stg2 not +fmic. i thought this would make more power than the oct93 aggressive, but it seems like im creating less power.
i dont know if this is all due to linear throttle vs whatever throttle they have, but seriously the difference is huge where oct93 would wheel spin its ass and stg doesnt not. also you guys think it would be ok if i strap exhaust pipe fix tape and pull the dps and mid pipes together so they dont clank against each other...the dps are now so close together that they clank when under load or stopped at a light.

The difference between stage 1 and stage 2+ was very significant for me on my first pull (second pull not so much as it blew off my chargepipe). I dont know how you couldnt noticed it.
Also, what type of dps did you get and who installed? I have never heard of them making noise hitting eachother. |
