3.4 PCM reprogram

[V6DROPTOP]

1994 Firebird 3.4 conversion.
I put this into an 83 S10 Blazer 4x4 about 7 yrs ago and its worked fine.
its time to go to the next level and fix a couple of things.
I want to eliminate the codes for the transmission and tweak the PCM for alittle more performance.
It now stalls when decelerating and at times wont idle.
Does anyone know of an ALDL cable and software to use laptop on this?
Ive seen software for 94 LT-1s but none for a 3.4.

Im not aware of anything for the 94 3.4, nor a definition file for the chip itself to make tweaking it easier.
