    throttle jerk off idle help

    ive been working on a tune for the 3.5 ecoboost and for the life of me i cant figure out where the idle blip is coming from.

    when idleing in drive and applying light throttle i get a tps of 20~ for a split second and cannot figure out where its coming from.

    does anyone have anything or look at it for me?


    ive attached the tune and the log showing it.idle jerk tune.hptidle jerk tune.hpl

    1st, you need to add all type of sources channels into your log. So others can help u. We can't get any idea from your current log.
    Try adding throttle sources, torque source, fuel source, VCT schedule mode.
