I have now pulled the binary from a 63B72 ECU using my Romreader PCB:

http://www.rhinopower.org/ECUs/63B72/docs/63b72.bin

The code makes full use of the 76C40 processor's capabilities, so a 6801 disassembler can't be used. I will publish the source code in due course when I have run it through my own disassembler.

I don't have a datasheet for this processor, I can't find any reference to it at all. I saw your comment on your website about the similarity of your processor to a 6801 and checked this one against the 6801 datasheet. This one has the same pin out too so I thought I'd see if it would run 6801 code and it did. I will publish details of the PCB I used, running the processor in mode 0 (Test Mode) I was able to pull the binary.

Thank you for valuable information.
My project is dormant now but it should wake up when we approach summer.
Do you have data sheet for TMP76C40 ?

This looks to use the same processor as the TCM here:

It would be possible to modify this ECU using a daughterboard.

Hi Juha
I have been looking at your schematic again, pins 8,9 and 10 on the processor should be the mode select pins if this is a 6801 derivative so I would expect some resistors on these pins. Pin 8 is pulled to 5V but I think that pins 9 and 10 should be too to select single chip mode.
Cheers
James

While gathering parts for SJ413 EFI conversion I have drawn schematics of Denso D3 ECU used at least in older 8V 1.3 Swifts.
