    N55: SSP Clutches installed

    2010 N55 135i, Wagner IC, Wagner downpipe, AFE intake, Cobb AP. 90k miles.

    Recently, my DCT clutches started slipping, at first only when shifting 5>6, then in all gears from 3rd upwards.

    So I...

    today i tried upping the WGDC spool table by 10% but didn't like the result, car became very jerky after stepping on it, just didn't feel right.
    the car also showed some misfires in 2nd gear...
  3. N55: IIRC, before i got rid of my misfires, they were...

    IIRC, before i got rid of my misfires, they were not obvious in the log; the only hint was a kink in the rpm graph. id have to look at my older logs, but i am pretty sure requested load will not...
  4. N55: that is the classic misfire when the load limit...

    that is the classic misfire when the load limit is set too high. you are right that raising the load limit will help you get rid of TCs , but then you will run into the misfires again. so you will...

    that is a very clean log indeed, especially the relation between req. and act. load is very constant and smooth.
    i have the post shifting timing drop too, not sure if it is something to worry about.
  6. N55: i had misfires like crazy, all of a sudden, when...

    i had misfires like crazy, all of a sudden, when the weather got warmer this spring. started changing EVERYTHING described in various threads (plugs, coils, HPFP, whatnot...), to no avail.
    then i...

    i think you are right about the car using timing to achieve target load.

    id like to be able to establish the throttle plate not closing as much as in the log. i have since decreased WGDC a...
  8. N55: there is more than one table that can taper out...

    there is more than one table that can taper out power in the upper range (i don't have my laptop with me, so i can't exactly recall which ones). to up the power, i reworked the "load tables", but i...
  9. N55: a wheel hop seems plausible as the rpm jump up...

    a wheel hop seems plausible as the rpm jump up almost 100rpm at this point.

    if you are sure your hardware is ok, misfires come from a map that is too aggressive (the car requesting too much...
  10. N55: i think the timing corrections from TCs come when...

    i think the timing corrections from TCs come when the DME slams the throttle plate shut. a smoother and more "modulating" behaviour of the TP might not cause that severe timing corrections.

    if...
  11. N55: in my experience, immediately after a flash or...

    in my experience, immediately after a flash or when you have reset adaptations, the car runs just great, lots of power, smooth power band. after a while, TCs reappear and drivability suffers.

    the...
  12. N55: do you log immediately or shortly after flashing...

    do you log immediately or shortly after flashing a new map or do you make a few pulls before? i often thought i had things sorted only to find out that if i log another run later or the next day...

    Josh@Cobb

    Josh, in any table in ATR, is it possible to change the value of the column or line header and will it do anything (for example, the last column in the ignition table is valued at an...

    uninstall... ;-)

    i have no more TCs whatsoever, partly by reducing WGDC but also by raising the load/torque limit tables

    but now i have misfires i can't get rid of (only when tuned).

    we lost...

    thanks for the reply
    went out yesterday and again had massive TCs (sometimes not just a spike but over a range of 1000rpm). and i will definitely contact PTF, but like you, i like to mess...

    going through Cobbs OTS maps database, i chose a stage 2+ sport map because it matched my mods list best.

    all logs show TPS act., load req. and load act.
