No part numbers or any markings on the decoder. It plugs into the like OBDII port of a car on the sled. So where I would plug in my scan tool. There is only one xdf file for this application. What I have concluded is that the ECU is able to read both chips and the 8k was apparently done useing a different program and so I can only copy and burn it but unable to read it correctly and modify it. I wish there was a way to read it, but it seems to be what it is. Seems to have been done in a way to protect the fuel map on the chip so others could't copy it. Is there an easy way for a non-tech savy person like me to take the 512 chip and make it like this so it is protected?
