I was going to take a look at the sensor that is running on my 1996 Aspire. Anyone have a data sheet on the O2 sensor for a 96 aspire?

It's a narrowband sensor, just like every other narrowband on pretty much every other car.

Either way, there has to be a way to fool the engine ECU to a certain level to make it run clean. The other option is to get a $550 dollar SW hardware package for a laptop to make it run leaner, but I don't want to spend that kinda money.

There is. You have to buy a wideband sensor. A laptop cannot make it run leaner because your engine still doesn't have the proper sensors to maintain a lean mixture.

This isn't impossible, but all you are saying is do it on the O2 sensors instead of the intake as long as you do the mod correct for your sensor. I still see a benifit of being able to run leaner at any given air temp so that you can take it one step further than a HAI, isn't this what the sport is all about?

I'm saying adding any amount of electronics to a narrowband O2 is ineffective not because leaning isn't effective, but because it won't accomplish leaning. The IAT is flat-out ignored in closed loop mode. Your scangauge will show improvement because IAT is part of the formula it uses to compute fuel usage, but when you go to fill up, you'll realize that you've burned more fuel than it thinks you did and that there was no improvement.

People are putting pizza pie pans instead of hubcaps to maybe get .5 mpg change... this is obviously has a better potential for improvement than that.

Of course it is. I found a 10% improvement, but I leaned my car out properly, with a wideband. Trust me, I've screwed around with narrowbands, and you have no way of knowing what mixture you're running at. To run at your most efficient AFR you need:
1. A wideband O2 sensor
2. A signal converter circuit
3. Good injector-based instrumentation or fillup method (NOT ScanGauge!)
