Dag, interesting reading mate!
You really are into your tuning, If ESS was closer i would prob use them for the 335d Yours is still dropping off power after 4kishtho isnt it. Carlos

What correction percentage did you use to get crank numbers? Last edited by dagjohnsen; 01-14-2008 at 01:49 PM.. |

I guess most turbo cars including petrols loose some power in the last 1000 rpm or so. Even the twinturbos, 335i and 335d included. Even a Boxter S loose power in the last 500 rpms, but the 911 Carreras doesnt. Think Porsche did it on purpose to keep the Boxter/Cayman below the 911s. By the way I would really like to have a 335i with a sports exhaust Last edited by dagjohnsen; 01-14-2008 at 01:51 PM.. |

My 335d made 310bhp at 4800
I would love to see a real 350-360bhp at the flywheel and 290-300 at the wheels. Carlos

Carlos, why dont you just ship your ECU to ESS and let them have a go at it?

Im I wrong??? Dont want to be silly here, just what I could read from the dyno. Anyway, that twinturbo is really revhappy! From 4450 to 5000 is just a blink of the eye really. Does the revlimiter go past 5000 rpm or does it stop at 4800? |

I do think the reason for keeping the hp low is some kind of limitation such as the fuel pump etc.

Dag, with those performance figures you need to invest in a new badge, like I had on mine.
This will really confuse the 330i drivers and Boxster owners. Last edited by mikem; 03-04-2008 at 01:00 PM.. |

But the four exhausts confuses me! Did you mod it or is it photoshop? Did the sound change? Price??? Looks nice! By the way I have no badge, the E92 doesnt come in 318d, the smallest one is the 120i..... Could be fun! |

Exhaust was custom made by Powerflow and sounded strange. Quieter than stock (if thats possible ) on a light throttle but at full throttle sounded like a Jet whoosing past at low level.
Theres a short sound clip here. |

Or somewhere in between... I just asked for a map with good performance but still good reliability since its my every day car. The down time on your end is up to the shipping you choose, you could do overnight and have it all done in a single work week, the reprograming it self takes about one hour. At least give them a ring and tell them what you're looking for and if they can help you achieve that www.esstuning.com

yes, seems like 310ish between 4000-4500, thats why BMW put one small and one large turbo! If you chiptune, that wont be the same anymore, even if its a good one. You will have the largest increase around 3-4000 I guess, and still a good increase all the way up to the limiter, but my guess is a slightly falling powercurve above 4000 rpm. By the way, the 335i powercurve starts to fall at 5600 rpm, thats 1200 rpm before the limiter. The 335d at 4400 rpm from the dyno done in Sweden, so my 4450 wasnt far off. Its easier to read those ones, here is a link: 335i: http://www.rri.se/popup/performanceg...p?ChartsID=647 335d:http://www.rri.se/popup/performanceg...p?ChartsID=688 |
