Apologies, Back from the Dead!

I searched for several hours, but can seem to get a concrete answer.

My question is if the ECU is flashed to Stage 1 or 2 via Cobb AP does it make the ECU dumb? Meaning the ECU will not adjust Timing when it detects knock, it will only read the MAP(stage 1 or stage 2) that is flashed into the ECU no matter what.
Will flashing eliminate "stored learned memory"? as the ECU learns as you drive and adjusts air/fuel, timing, etc based on sensor readings

I'm hoping COBB can chime in this...
sorry if this has been covered on a previous thread

This is my first Subaru Sti
I used to own an Acura RSX type-S supercharged tuned with Hondata Kpro.
Hondata Kpro made the ECU dumb it only follows what ever is on the map.
There are parameters though that you can set like Temperature compensation, Timing retard each gear and fuel cut-off when the AFR is too lean and many more.
