96 LT1 PCM Programmer

[Programmer]

Names not Mike--but that's ok...thanks for the response. The dealer unit I'm
using stores the OE file and reprograms with a new one (as far as I know at
this point). I'm a little reluctant to do any hacking with this thing--if I
lose the OE file, I'm kinda stuck when the customer comes back for some
changes <g>. I don't want an added expense of a new PCM for a fella. I guess
I could get around this if I purchase the SIS system through
Vetronix/GM...but that's a $1500 a year subscription fee...keep me posted on
the software !!
