Good thread as usual LBGT.

But if there is such a thing as DA, FBKC, and all the rest of Subaru's knock handling ability, for which it is much praised, then why the concern? There are even special maps for when knock gets so bad all the normal maps don't work anymore. Given the variability in fuels these days, added to all the environmental variables, it would seem impossible for any car to be det free all the time.

Back when I got my AP the Cobb maps almost always had some pulled timing. Later, on TDC eTunes the same pattern was there. No one ever said a couple of degrees of DA being pulled was terrible. The only warning was to make sure it never went into MINUS DA.

Is the point of this thread to assist in the development of a well rounded tune? Or is it pointing out that having anything other than perfect DA is a motor killer.

If this motor is that sensitive and that fragile then a) Subaru's knock control is a joke, and b) abandon all hope for a long lasting turbo motor because perfect DA all the time ain't gonna happen.
