BTW have you tried with TCS off? sometimes it cuts throttle in 1st/2nd before long before the slip indicator comes on.

VDC was off, logging was done via uprev which most definitely uses canbus (my pm was about something else entirely). the delay is not only very clear in logging, but its extremely noticeable when driving, which is why I started logging to begin with. it seems that the behavior is not consistent from car to car, so your logs may not show anything near what my car does. further, when the car is cold the pedal and throttle lag are almost entirely gone, but i use the term "cold" loosely here as the water and oil were already warmed up since its summer, so I have no idea as of yet what is causing the lag to occur after a bit of driving.
my next step is going to be disabling ETC entirely and seeing if the lag is gone, which would mean the issue could be solved with the throttle maps.
