Chris I think it is the ignition curve that is in the engine now and an electronic distributor that are calming this beast.
The fuel curve is just going to keep the a/f ration optimized.
I remember the days of just two parameters for FI. Oxygen sensor and throttle position.
I personally would not presume that someone did not tweak the program for that cam and compression ratio on pump gas...although I would NOT argue vehemently against that comment that it is the current standard default.
It's true that the "default" settings on everything have become more sophisticated and you can always pick up last years ECU on ebay as soon as the new models are available.
I wouldn't be good enough to write the ignition curve anyway. I would be trying to fix points in the curve that are not fixable necessarily.
