Ive started work with the OBD-II PCMs and have a basic set of tools so far (assembler, disassembler, various reference manuals, etc.). But, Im trying to figure out how to best get the calibration off of the flashROMs. I saw on DIY-EFI that this had done this earlier by using the BDM to get the 68332 to offload the ROMs. It shows how to add the provisions in for the BDM, and some basic shots of the connector and hardware, but the software and most of the schematics are long gone.

Any of you guys have experience with BDM, and maybe where I could get a controller board and drivers? Seems like this has been done before, but was lost when diy-efi's server went down.

 

Is it a 2x5 pin .100 pitch header?

 

I believe so...

 

Somewhere I've got some that are for 68k and some that are for PPC (or CPU32 and CPU32+ actually). You'd need a parallel port and software (which I may or may not have).

 

Let me see if I can get 68332 development demo board. It usually comes with software development tools and schematics. No promises, I'll see what may surface...
