OMEX200 to OMEX600 conversion

[galiza]

Hi, i have two Omex ECU?s

OmeX200->8 ignition channels (only ignition)
Omex600->4 ignition channels+2 inyection channels

Inside,ECU are both equal.
Microprocessor Motorolla 9S12??512
Eprom 27C256

But in Omex200, eprom has a sticker that says OMEX200, and Omex600 says OMEX600.

Reading and changing eprom you can convert your OMEX ECU.http://www.digital-kaos.co.uk/forums/attachment.php?attachmentid=307749&stc=1307750http://www.digital-kaos.co.uk/forums/attachment.php?attachmentid=307751&stc=1

M8,
Probably if you change the content of processor and flash will get better results

hi friends. Can you share the dumps from both models? FLASH+EEP from 912MCU and external flash.

I think that the program is in the Eprom for three reasons:

1? The Eprom is not programmable (OTP EPROM), then maps may not be there.
2? Both PCBs have written "OMEX 600" (YES, the PCB of the Omex200 has written Omex 600)
3rd I tried it and it works.
