PCM setup for V6 Camaro 1997

Hello, I have a 1997 V6 Camaro Rally Sport, I've seen the connector underneath the wheel by the pedals.

Is there some software out there that will let me edit the parameters of my engine's computer? I want it to also be able to display all the system stats in real time, if that's possible.

I ask this because I've seen lots of software for the 5.7 engine but haven't seen anything for the 3.8 that I have. I'm assuming I should be able to since the whole computer system is still there.

I have a laptop and the ability to create any type of cable I need, as well as program serial EEPROMs and Atmel, Microchip (PIC), and Scenix MCUs. I don't know what else might be require, but please, let me know.

Thanks,
Kyle Curre
