Loaded the stock chip to the autoprom buffer using the 27C512 as you suggested and it formatted the file as needed for the XDF. I just had to make the addressing start and stop values match in the "chip addressing" and "buffer addressing" boxes. I think im now moving in the right direction because the values are matching up on my compare screens, between the bin from the tprt website and the one i sucked out of my ecus stock prom.
Thanks for the help.....
