Hey Larry,
I know with the 1G cars (not sure about 2G cars) the ECU learned over time if you had a knock problem and would put in a long term knock correction factor into the timing curve. One of the things Todd Day did with his ECU mods was to make this factor "re-set" to the highest value on every startup instead of keeping a more conservative knock curve if some family memeber put 87 octane in your tank.... it had to re-learn every time, but it also gave you max power on every startup, as long as you were running good gas all the time it was a great modification. As far as the instantanious knock correction on the EVO's, it decays away over a short period of time even if you don't go to zero throttle if I remember correctly. Don't quote me on that though
