Don't made it on Denso diesel ECUs, but done on some Mazda Denso benzin and Nissan GT-R ECUs with 7058 mcu inside.
Rewrite full SH MCU dump using free Renesas FDT tool (maybe piasini also can do it) and separate serial eepom - works OK.

Yes, this is a 7058 based ECU.

I have a full flash read, and was planning in reading e2p with a programmer.

OK,i understood the part with eprom programmer,just wondering about flash,I assumed that you read the flash by programmer too....

I may be wrong but I thought immobiliser data is in flash and E2P was for adaptions.
Either way I think you'll be fine
.....post results when uouve had a play.
