I've searched all the threads I could. People have claimed that the MH8202F is in fact a hitachi H8/5xx processor. I then procured all the datasheets I could on those processors and couldn't find any in the 240 pin package found in my ECU. I have obtained a map file from alternate means but have been unable to disassemble it using ida pro. I'm wondering if in fact the H8/5xx idea is not correct.

maybe it is not, maybe it belong to SH7052 or some other CPU.

MH7202, MH7203 are H8/500 cpu.

I checked and none of the stock SH series have that pin config either.
