    Default Power cut out

    Ok so the last few days when ive been giving it some out of long corners in 2nd gear, the traction light comes on much more frequently thanks to my trusty new DP. But then all of a sudden the power pretty much gets cut in half for a second. Its a pain in the ass! Is this due to the DSC or steering angle sensors that are steeling my fun??? Or am i coming across something else here? Fuel cut, Boost cut???
    I havent tried with the DSC off as yet.

    Thanks guys!

    Sounds like you're overboosting (byproduct of the DP) which is leading to a fuel cut. Got a Dashhawk so you can see what's happening to the fuel pressure vs. boost?

    Any other mods like an intake?

    Ahh OK, hadn't heard of the Dashhawk not working with the Gen 2, wasn't aware of that.

    With all those mods I do think it's overboosting leading to fuel cut. Have you had it on a dyno to check that all is running OK, mainly looking at AFR's and boost.

    Also, after DP install did you putt around for 50km or so to give the car the opportunity to relearn/reset the LTFT's?

    I have a DH if you want to come and take some logs.

    Under what circumstances does it happen? Only when turning or when in a strait line?

    Not sure i gave it quite 50ks to relearn. I can just disconnect the battery to let it relearn again to be safe right?
    It hasnt happened in a dead straight run which made me think it was the dsc or steering angle sensors.
    might have to get it on a dyno to be safe.

    Default Power cut

    Hey cotn, try to repeat circumstance. Watch revs,turbo gauge,speed. possible speed/torque limitation in 2nd, Remembering this car has restriction in 1st &2nd. WOT will induce slight power drop in either gear at pre set limitation. Possible cause???????

    Hope this helps, at least isolation of poss cause.
