Reverse Engineering ECU
For anyone who would like to help out and knows C and SH2A-FPU asm. Im working on a project and im asking for whatever help I can get.
If your interested the project is over on github all the tools are included all you need is a windows computer https://github.com/reverseslayer/FRS-ECU |
Don't know squat about this, but subbed.
|
@ztan did revolutionary works after analyzing disassembled ROM.
|
subbed
|
best chancexwill be contacting guys at romraider.com
http://romraider.com/index.php/RomRaider/RomRaiderTeam specificly td-d and dshultz |
td-d developed Romraider.. that explains a lot, doesnt it. lol
|
td-d, ill get in touch maybe he would be interested.
|
I can barely program the tv remote. LOL
Help if I can. I have 4 PWMs outputs I'm not using so it would be great to use those. Would love to delete these Exhaust cam sensors also. K24 ran with brz ecu. |
Here is the disassemble guide from RomRaider forum.

I would use IDA except for the fact the the free version doesn't support this cpu architecture. So I would have to buy pro and that is a bill that is around $1000. I have found a 3rd party open source software called ghidra that can also decompile sh2a-fpu. It is defiantly not on the same level but the fact that it is free makes it very compelling.
That tool might help me map to memory locations easier because my plan was to just zero them out so i could focus on the code but if I could keep the tables and just label them it would make more since so thank you |

..I don’t know why I want to do all of this even though there are currently xml files with all the identifiers for tables |
You only lose your time in something that was already done

Well only because this tool is amazing, especially since its free.https://i.ibb.co/x7Db5j6/Untitled.png |
For science! I know how to adjust the tables and numbers but I have no idea how they got to where I can make these adjustment. Wouldn't mind learning. For science.
