You can't flash anything over this hardware crypt panel.
If you want to change something you must delete this hardware addenium, place pure flash chip on the board and recover ECU in bootmode to original state.
Then you can start tune and flashing as usualy. 

 

any clue why i was able to flash a file from here also a stg 3- file and have the rear o2's and egt's coded out?

Some "encryption" boards simply swap around a few address/data lines.

In theory, there are several address/data lines you could swap around without affecting CFI (or flash vendor specific) eeprom flashing commands.

They may have intentionally selected lines such that is the case to continue to allow flashing through OBD.

Or maybe, just happenstance.

If that is the case, there is no reason why Galletto flashing wouldn't work as is. The contents of the flash is "encrypted" but the ECU sees unencrypted data, whether it is running a working car, or the in the middle of boot mode read/write.

That type of "encryption" btw is only intended to make reading the flash after desoldering it a bit more difficult.

Just a wild ass guess, though.
