Well seems today is a good day to update with Inferno running amuck
This is the "Brain of the PCM" it is a Freescale MPC5554MZP80 processor.
This is my best guess where your B&G Flash goes.
It does not hold the really important info we need to modify to tune
it just runs the PCM and orders commands.
Unlike this Monolithic IC which is a Freescale 95320WQ EEPROM 32
bit w/ SPI bus this
is where all the "real tuning" tables are stored.
Yes the board is about 25 percent identified.
In several weeks I may have enough Nodes and have power to the bench setup.
Then a real conversation with me and it can begin.
