I concur with Harold's recommendations. I brought up the same question a while ago and Harold recommended the door/key/pedal sequence to me and it did help. For a while at least. 
I am planning to do the transmission valve pressure mod this spring/summer and I have been trying hard to study what I can to figure out if it is possible to just turn off this silly learning feature. It saves on gas, definitely, but it is a bit embarrassing when you try to go and the car just lags.

If you could find a way to put that de-acceleration beast beast to rest, you'd be enshrined in the SC430 Hall of Fame just on that one accomplishment! The first time I experienced it, I realized that it is not only annoying but dangerous. If I have to accelerate out of a bad situation on the highway or street and the ECU decides otherwise, it could easily become crunch time, if you know what I mean.

Yes, unfortunately, after the reset the ECU starts over its granny adjustments.

EDIT: Considering, if you could find a suitable replacement.

The new ECU would do the same thing. The ECU learns how you drive the optimizes shift points, downshift points. It just seems as though the sc430 takes this to a bit more of an extreme. Like I had said, I have seen and heard this on other cars. I wouldn't have explained it as bogging down. More as lazy, not down shifting till wide open throttle. Shifting early, so as causing slower acceleration. A new ECU will just do the same leaning process. The only answer is yo reset it if it becomes this way, or drive it harder sometimes to change the learning process. Hence my half joking comment about needing to drive it like you stole it more often.
