95 RM wagon LT1. I noticed the program for the transmission has a seoerate table for "performance setting" I don't believe this is being used on this car as both tables seem the same. Where is the signal input to use performance mode? I noticed some cars have a switch near the shifter for this, can I add a switch and use it to choose between the 2 tables?

I installed a lighted pushbutton in my 95 to switch between normal and performance mode.
Pin 13 on the gray connector is the mode switch. Install a momentary pushbutton that grounds this pin.
Pin 15 on red connector is the lamp. The PCM provides a ground on this pin when the performance mode is selected. I don't know how much current this pin is designed to sink. The pushbutton I picked has an LED built into it and I added a 1k ohm current limiting resistor to keep from blowing the LED.
I can't find the switch on Radio Shack's site, they seem to have really cut back on their selection...

I have a program from an Impala SS, I wonder if i could cut and paste the performance mode settings into my Roadmaster program.

The Impala SS didn't use it in the PCM either...the only car that did from the factory as far as I know, was the trans-am. Basically, you can up the shift points a bit and I think you can also change line pressure in some other places...so if you copy stock tables into the "performance" ones, then mess around with it all just a bit...you can see what changes you like and what you don't and go from there.
