Every four-banger w/ automatic transmission I have ever owned has been SLOW AS SHIT (unlike more powerful cars: TransAm, Supra, 300ZX).
Your "quick shift" ECU is probably just an add-on that will provide constant line pressure, like the HKS ALC does. While it will help, do not expect any monumental changes. If you insist on keeping it automatic, you will need to put an actual shift kit in the valve body and adjust the shift points. It made a world of difference on my Z; feels like a whole different car.
But if it is just for show, I wouldn't bother. Just get a shiny shift knob and call it a day.
