This is a summary of the steps and tools required to disassemble, reassemble, link, trim and re-flash Evo code into your ROM. It was pulled together from many threads on the www.evolutionm.net site, to make it easier to figure out how to do this for anyone who wants to get into coding their own mods to the Mitsubishi ECUs. It is an open work in progress, so feel free to make any corrections or additions as needed.

 

Wow. Good stuff. I want to learn more about this so I can change software in all kinds of modules (Not just for tuning type work)

 

Thats awesome, thanks for uploading! is it compatible with older h8 ecu? im sure its same but different.. time to dive in and start reading!

 

Yep - same process with minor changes for the Hitachi/Renesas H8 processors. IDAPro 6.1 even has processor options to disassemble the SH8 family code. I have no direct experience with the H8 but there are plenty out there that do.

 

Does anyone have the SH7052.idc script which is now dead-linked in the PDF?

 

It's all freely available...improve your search skills grasshopper!

Thanks, CDrinkH2O

Yes, I found this earlier when searching around, but I wanted to use the exact idc mentioned at least for the initial attempts.

Based on your recommendation, I'll assume these are the same things and I'll thank you once again.
Also, thank you for this initial work and post.
