Just continue reading, nothing to worry about.
You can always use 29F800BB layout for reading, worst case is the 512kb flash is duplicated in a 1024kb file.
You can also open up the ECU and see the model yourself.
I'd recommend studying this forum further as all your questions were answered before
I am sorry, I am genuinely trying to search for the answers I need and I am not finding some of them. I will not post any further questions. My apologies.
