What kind of chip is it? I know the older ones use a 27c256. But what do theflash ones use? I ask because I have a chip burner now that I use for slot machines and pinballs and such. I have orginal .bin files. I just don't want to take my ecm apart right now. I am wondering too because I *think* i can use a 27c256 in the place of the flash rom.
