The dreaded 4K RPM power dip - 5 minute fix?

[ELCID86]

Has anyone else tried this? Outcome?

I forgot to post my outcome. lol
I cleared the adaptations entirely a month or so ago. It helped some, but the dip is still ever so slightly there. It doesn't bother me much as I'm used to it; it's not as bad as it once was. I've done the DISA rebuild as well and the issue was almost entirely resolved after doing the DISA. The reason I ended up doing the adaptations was due to very jerky throttle actuation at low RPM and low speed and throttle input. Clearing the adaptations helped quite a bit with that, but I still have issues with it. The dip is still slightly present.


I can't iterate this enough: I hate drive by wire.

would this cable and disc work in order to get to this clear adaptations task?

Has anybody else tried this method? Results?
Thanks

If it's ALMOST gone why not try tuning it out?

Yeah, clearing adaptations get's really close to getting rid of the dip. It comes back, though.

kinda like you.

If the DISA is the source of the false knock detection, then it would seem logical that you would need to replace the DISA with the newer version (if there is a newer version) and THEN clear the knock adaptations.

Otherwise I would expect it just to come back.
