The video was a little hard to watch like most of youtube. I was amazed to see the use of a heat gun ON the chip. Never realized they could withstand the heat in order to melt the solder. I see he replaced the capacitors. Back in the 80s many failures were due to the dielectric drying out in them. Someone mentioned using a ZIF socket to easily remove and replace the eprom. I still suspect the solution could be to get around the skreem altogether by making the ecu think it has perpetually verified the security but I'm way out of my league. Sometimes the answer starts out of the mouth of babes..
I have a lost co-worker that took at least one of his crossfires out of state and had the security removed. I'm going to try and locate him to ask just what it took to do that. Hope it isn't a dead end..
